[5:11] <raulp> hey guys, if GPIO.setup(PIN, GPIO.OUT) is always high ... means that my GPIO is ... good bye?
[5:14] * semeion (~semeion@unaffiliated/semeion) has joined #raspberrypi
[5:15] <retrosenator> ?
[5:15] <retrosenator> what if you set it to input
[5:15] <raulp> then it turns off
[5:16] <raulp> it's weird, cause i have a 16channel relay plugged in, nothing on it
[5:16] <raulp> just PI + relay. and i played with some scripts ... and somehow... it broke
[5:16] * mnemonic (~semeion@unaffiliated/semeion) Quit (Ping timeout: 240 seconds)
[5:16] <retrosenator> you should use optical isolation
[5:16] <retrosenator> because relay coil have inductive kick
[5:16] <retrosenator> at least use zener protection
[5:17] <raulp> ok, i should have: 1) read about it more 2) watched more videos, not 1 ....
[5:17] <raulp> god damn it
[5:17] <retrosenator> maybe another io port works?
[5:17] <raulp> after i burned 16th .......
[5:17] <retrosenator> there are more than that
[5:17] <raulp> after i burned 16...
[5:17] <retrosenator> you burned all 16?
[5:17] <retrosenator> wow
[5:17] <raulp> yeah man
[5:17] <retrosenator> I never burned even one
[5:18] <raulp> that's what i'm saying, not sure how is that even possible
[5:18] <retrosenator> but I use optical isolation
[5:18] <raulp> i used a python script to just TEST
[5:18] <retrosenator> if I didn't i would have fried more than one pi completely
[5:18] <raulp> setmode bla bla, and of course, did some mistakes
[5:18] <retrosenator> I blew up the optical isolator twice
[5:18] <raulp> my PI is good, just my GPIO's are dead
[5:18] <retrosenator> try the gpio command
[5:19] <retrosenator> it may be possible to fry all the gpio at once

[5:19] * orti (~orti@p54A627EF.dip0.t-ipconnect.de) has joined #raspberrypi
[5:19] <raulp> what about the gpio command? i tried some test command gpiotest
[5:19] <raulp> that is the one that told me all is messed up
[5:20] <retrosenator> run "gpio" at shel

[5:24] <raulp> gpio readall
[5:24] <retrosenator> yeah
[5:24] <raulp> gpio readall ?
[5:24] <raulp> sec
[5:24] <retrosenator> then try shorting one of the ones set to input to ground
[5:24] <retrosenator> or 3.3
[5:24] <retrosenator> and make sure it works
[5:24] <retrosenator> but don't do it to one set to output
[5:24] <retrosenator> unless you use like a 500 ohm resistor
[5:24] <retrosenator> maybe should do that anyway to be safe
[5:24] <raulp> htpps://pastebin.com/s5dqEbxS
[5:24] <raulp> https://pastebin.com/s5dqEbxS
[5:25] <retrosenator> so try connecting one of them to gnd
[5:25] <raulp> =let me get back to you - shit, i have a call from work :( basically that's what i have - and i wanted to show you a pic, but the pic will be straightfoward
[5:25] <raulp> PI => 20 cables => 16 channel relay
[5:25] <raulp> 2x 5v, 2x grouonds, all others 1-1
[5:26] <retrosenator> disconnect all that
[5:26] <retrosenator> and just wire one gpio pin to gnd that is reading 1
[5:26] <retrosenator> from gpio readall
[5:27] <retrosenator> and see if it changes to zero
[5:27] <raulp> right you are
[5:29] <raulp> give me a sec
[5:29] <raulp> in call for work, cause why not, it's only fri night

[5:31] <immibis> 16-channel relay boards often have the driving circuitry built in, but you should check for your board probably
[5:32] <immibis> i'll also point out that if the output is stuck high, but input works as input, you can still use it by switching it between output and input :P
[5:35] <raulp> @immibis true, but ... i want to learn WHY the hell that happened.
[5:37] <raulp> @retrosenator https://pastebin.com/xnCQGP96
[5:37] <raulp> let me take a picture of what i have
[5:38] <raulp> https://drive.google.com/open?id=1lxiZ-VOgK0r6fm6v3bicVm52-6F6VzD8
[5:40] <raulp> basically i followed https://www.youtube.com/watch?v=TFt480sxNWg for the setup. not for the script. and my PINs were just a bit different (i did not use 2 3, and used 0)
[5:40] <raulp> but setup is almost like that one
[5:41] * sigsts (~sigsts@unaffiliated/skyroverr) Quit (Remote host closed the connection)
[5:46] <raulp> i should probl go back to the LED example ... lol
[5:46] <raulp> and start from scratch
[5:46] <raulp> and see if i can get these pins to reset ... not even sure what is broken now.
[5:46] <raulp> and if i don't figure out what the hell i did to break it ... then it's bad.
[5:46] <raulp> cause i'll do it again...

[7:42] <ShapeShifter499> I was poking around, my Raspberry Pi 3B+ was crashing with memory issues and kernel panics Most recent one was: https://gist.github.com/ShapeShifter499/8c43fca9b6404126c6971564d695be4b I found some suggestions online from https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=208821 So I ended up adding sdram_freq=500 to my /boot/config.txt and the issues SO FAR have gone away. Does
[7:42] <ShapeShifter499> this mean that the RPi 3B+ RAM was actually too slow for my use case?
[7:43] <ShapeShifter499> at least whatever the default was
[7:44] <ShapeShifter499> Use case was running rsync on two encrypted USB drives, moving multi-GBs from one to the other

[8:21] <ShapeShifter499> genr8_: do you know what that means exactly?
[8:21] <ShapeShifter499> or any ideas?
[8:21] <ShapeShifter499> genr8_: I did just get another crash
[8:22] <ShapeShifter499> https://gist.github.com/ShapeShifter499/3af51b6c3d87c07e300110f81e162df8
[8:23] <genr8_> that ones more serious
[8:24] <ShapeShifter499> I don't know what is causing it
[8:24] <genr8_> check the SD card for damage in some kind of flash scanning program
[8:25] <ShapeShifter499> genr8_: the SD card is fully encrypted. I make use of a initramfs hook to decrypt it over dropbear ssh
[8:26] <genr8_> thats fine, just check the flash, cause this time the error occured in the dm_crypt module which aligns to what you just said
[8:26] <genr8_> doesnt matter if it can read the files or not, it checks the cells

[8:27] <AfonsoHenriques> Hi everyone. I'm looking for a system that we can manage (create/edit) data (credentials, etc) using RPi as a server; to access ( = login) into such system I'd use the LAN IP connected to the RPi
[8:27] <ShapeShifter499> genr8_: I'll check the card right now, but all attached storage is fully encrypted. Three hard drives and the rootfs sd card
[8:28] * cave (~various@h081217094244.dyn.cm.kabsi.at) has joined #raspberrypi
[8:28] <ShapeShifter499> genr8_: that message popped up during a file copy using rsync between the attached encrypted drives
[8:29] <genr8_> maybe its just from too much IO or something again but it faulted in a diff place ?
[8:29] <ShapeShifter499> I have no idea
[8:29] <genr8_> this is what i use https://www.makeuseof.com/tag/chkflsh-checks-your-flash-drives-on-windows/
[8:30] <AfonsoHenriques> I tried to install the "seeddms", but, sorry in advance... The developer is a goddamn moron. Spent almost 10 hours figuring the fuck out the myriad of errors shown, then I find (yes, find) a "non official" tutorial - that I also followed, and guess... The final result was another alien error.
[8:30] <ShapeShifter499> genr8_: I'm trying to move data and I 'ctrl-c' to stop rsync when I see a crash show up
[8:30] <ShapeShifter499> both logs were from different rsync sessions
[8:30] <AfonsoHenriques> I'm looking for a thing like keeppass, but, you know, "made for Raspberry Pi". Any ideas? Thanks in advance.

[8:52] <genr8_> nope
[8:52] <genr8_> the vendor
[8:52] <ShapeShifter499> CanaKit?
[8:53] <ShapeShifter499> I brought from their Amazon listing
[8:53] <genr8_> amazon could possibly help
[8:54] <raulp> amazon is good, if it's in your first month
[8:54] <raulp> they'll take anything back :) tell them it stopped working )
[8:55] * mnemonic (~semeion@unaffiliated/semeion) Quit (Quit: WeeChat 2.1)
[8:56] <genr8_> never claimed an RMA but it should work even after the month
[8:56] <ShapeShifter499> it's been a few months
[8:56] <raulp> just try
[8:56] <raulp> i know i'll do the same if i burned mine by mistake
[8:57] <raulp> i'll just say ... a few pins and wireless stopped working ...
[8:57] <ShapeShifter499> so I guess I have to return the whole kit, it included a adapter
[8:57] <raulp> :)
[8:57] <genr8_> speaking of adapter
[8:57] <raulp> depends, sometimes they'll let you only exchange the broken part
[8:57] <genr8_> is it adequate for powering all the hard drives and stuff
[8:57] <ShapeShifter499> the plug was 2.5A
[8:57] * BenGrimm (~yearight@ has joined #raspberrypi
[8:58] <ShapeShifter499> I had a powered 4 port USB hub for the two drives that didn't have their own power, the third drive was a desktop drive with power
[8:58] <genr8_> how soon does rsync cause the fault/crash ? can you repeatedly test stuff ?
[8:58] * r0Oter is now known as r00ter
[8:59] <genr8_> hm. i guess that means the power's taken care of
[8:59] <ShapeShifter499> genr8_: it seems to hit 5 minutes in but I'm afraid I'm causing data corruption to the data on the drives
[9:00] <genr8_> you can do dry run simulations and output to /dev/null or something
[9:00] <ShapeShifter499> genr8_: it's also plugged into a UPS which I had set up and tested with my Raspberry Pi to provide graceful shutdown and a way to power back up when I'm not at home during a power outage event
[9:01] <genr8_> well the power's probably fine. that doesnt eliminate the hub as a point of failure, data wise tho
[9:01] <ShapeShifter499> well I'm lead to believe something is up with encryption dm_crypt since it's mentioned at least once
[9:01] <genr8_> im trying hard to think of ways it WOULDNT be the pi...
[9:02] <genr8_> yeah, that would be more of a memory operation than disk IO, is that what you're thinking, right?
[9:02] <genr8_> unless the dm_crypt module also handles the disk IO (don't know)
[9:02] <ShapeShifter499> maybe... I honestly don't know much about kernel messages
[9:03] <ShapeShifter499> I have mergerfs between rsync and the drives
[9:03] <genr8_> oh. it _IS_ part of the disk device infrastructure
[9:03] <ShapeShifter499> mergerfs is just a JBOD software tool that lumps all the hard drives into one folder
[9:05] <ShapeShifter499> I run linux everywhere so I'm testing the sd card on a different linux machine
[9:05] <genr8_> there may be a conflict between mergerfs and this stuff then
[9:05] <ShapeShifter499> so far FSCK thinks the file systems on the card is fine
[9:07] <ShapeShifter499> the SD card is a PNY 128GB I had laying around from a older Android phone.
[9:08] <genr8_> is the LAN connection heavily active during the rsync?
[9:10] <genr8_> cause the first error said somethin about the LAN, and when googled it returns just what i expected: "Kernel Panic with heavy network traffic"
[9:11] <genr8_> it might even be a well-known issue: https://github.com/raspberrypi/linux/issues/2538
[9:11] <ShapeShifter499> genr8_: I have rclone running a backup to google drive. I purposely set it to 60Kb/s since I don't want to blow through my ISP data cap
[9:11] <ShapeShifter499> it should total out to 150GB a month
[9:12] <genr8_> do you have a heatsink on the pi
[9:12] <ShapeShifter499> I do
[9:12] <genr8_> even the 2 tiny ones ?
[9:13] <ShapeShifter499> I checked temps during all of this, I top out at 72C
[9:13] <genr8_> idk... 60KB/s is hardly heavy use of the lan. and 72c is hardly overheating
[9:14] <ShapeShifter499> I didn't cover the metal piece with the raspberry pi logo in the upper left (usb facing right)
[9:15] <ShapeShifter499> is that the WIFI?
[9:16] <genr8_> yea must be. i dont have that one
[9:16] <genr8_> i wonder why i didnt get the B+
[9:17] <ShapeShifter499> I'm using a aarch64 kernel with Arch Linux ARM
[9:18] <ShapeShifter499> https://aur.archlinux.org/packages/linux-aarch64-raspberrypi-bin/ which just fetches the already compiled kernel from https://github.com/sakaki-/bcmrpi3-kernel
[9:19] <ShapeShifter499> I brought mine this year 2018 but my board has a copyright stamp of 2017. I wonder how early in production mine is
[9:19] <genr8_> now i'm mad. not because of the lack of wifi, because I thought i had the 3B+ this whole time until i just now go and look at it
[9:20] <ShapeShifter499> uh
[9:20] <ShapeShifter499> the stamp on the board mentions the model

[9:24] * mlankhorst (~kvirc@ubuntu/member/mlankhorst) has left #raspberrypi
[9:25] <ShapeShifter499> all of my data is haphazardly stored on my drives, I was hoping with the help of some software and the Pi to organize, share, and backup to google drive
[9:25] <ShapeShifter499> these errors are really throwing a wrench into my plans
[9:25] <genr8_> data is too important to lose it to an experimental kernel on a $35 computer
[9:26] <raulp> can you sync with lower speeds, and lower chunks? just to get it out?
[9:26] <genr8_> i run a full powered server that pulls a couple hundred watts
[9:26] <raulp> also, does it always crap out at over a specific file size? or it's just random?
[9:26] <raulp> Do you have a top output when this happens?
[9:27] <raulp> iostat as well
[9:27] <ShapeShifter499> I don't know, it was running through a folder of hundreds of differently sized files and subfolders
[9:27] <genr8_> hes worried his tests will endanger the disk, have any tips for making sure its non-destructive ?
[9:27] <raulp> i wonder if he can take an image, but shit, that could overkill it too :(
[9:28] <ShapeShifter499> I can move the drives to my desk and attach to my laptop but I don't have space for imaging a whole drive right now
[9:32] <genr8_> i thought of something. Using the bandwidth limiter would cause more IRQ interrupts and might be what lead to that error in the first place. What if you sync'ed at full speed, then instead of crapping out after 5minutes, you could see if it craps out after 5 seconds
[9:33] <genr8_> i really dont think rsync can break source files unless you tell it to

[9:35] <genr8_> you're reading from your 3 disks and sending to the cloud right? It would be more dangerous in reverse.
[9:35] <ShapeShifter499> genr8_: your mixing two different things, I was using RSYNC to move files between drives (--remove-source-files) and RCLONE in the background to sync changes done locally to the Google Drive
[9:36] <raulp> that's a lot of write and move and stuff
[9:36] <genr8_> oh. not good
[9:36] <raulp> i would suggest to 1) copy all out - have a backup
[9:36] <raulp> 2) see what you can do after
[9:36] <ShapeShifter499> RCLONE was rate limited to 60KB/s RSYNC was not limited and local copy only
[9:37] <raulp> if the sdcard is a bit "tired" + encryption ... god knows. but i would def just try a straight upload somewhere to see if it crashes
[9:37] <raulp> reading, as genr8_ said, should not affect anything
[9:37] <ShapeShifter499> raulp: I wasn't writing or reading to the SD
[9:37] <ShapeShifter499> unless logs
[9:37] <genr8_> maybe dont remove the source files. then it wouldnt corrupt ?
[9:38] <raulp> yeah, try that. lower the load ... see if it can go thru
[9:38] <raulp> i think the most important thing now for you is to have the files
[9:38] <ShapeShifter499> I had similar crashes with cp -a
[9:38] <genr8_> split the issue into two halves. the rsync local and the rclone cloud upload

[9:41] <ShapeShifter499> I didn't think the SD card mattered much in this case
[9:41] <raulp> he's using other disks ... sdcard is just the OS
[9:41] <shbrngdo> if you have a large capacity SD card with a lot of free space you're less likely to hit this limit
[9:42] <ShapeShifter499> shbrngdo: my IO is mostly through USB
[9:42] <ShapeShifter499> I also have a 128GB SD card
[9:42] <genr8_> hes only using the SD to boot. he has 3 external disks hooked up . merged together with mergerFS and then encrypted with DM_crypt and a filesystem on top (which FS btw)
[9:42] <shbrngdo> in that case I'd also be concerned about temporary files on the SD card and swap [if enabled] and things like that
[9:42] <genr8_> ah swap, on the SD card.
[9:43] <genr8_> maybe it wanted to swap and got bogged down thinking the card could keep up with memory accesses
[9:43] <ShapeShifter499> I have swap but I was monitoring that, I didn't see any swap happening. I was at 400MB of RAM
[9:43] <shbrngdo> you should be able to create swap files on external USB drives. pretty sure.
[9:43] <ShapeShifter499> I could have missed it
[9:43] * p71 (~chatzilla@68-187-65-81.dhcp.ftwo.tx.charter.com) has joined #raspberrypi
[9:43] <shbrngdo> you should disable swap, see what happens. you might not even need it
[9:43] <ShapeShifter499> my system crashed outright when SWAP was on my hard drive
[9:45] <genr8_> are the drives OK? weak sectors with high latency ?
[9:45] <ShapeShifter499> SSH would hang then my syncthing connection died which is how I could tell the Pi just failed
[9:45] <shbrngdo> in my opinion, using swap with SD is somewhat pointless because of relatively slow write times and whatnot
[9:45] <ShapeShifter499> I'm not 100% sure, I know FSCK reported the drives were ok
[9:45] <shbrngdo> well USB is shared with the network
[9:46] <genr8_> he said he was only using 60KB/'s would that little usage affect sharing?
[9:46] <shbrngdo> you create a network I/O and swap and disk I/O bottleneck, and reveal an instability maybe?
[9:46] <genr8_> it does tend to sound like that

[9:48] <shbrngdo> overheating "just that part" of the CPU chip might be affecting things too. if the rest of the CPU is ok, but the part that does the USB and ethernet and whatnot is overheating, maybe you get a glitch that causes a hang [or similar]
[9:48] <shbrngdo> so could still need a fan, or a heat sink, etc.

[9:53] <shbrngdo> the RPi3B (not +) is known to have overheating problems anyway. reminds me of 486's back in the day "you don't need a heatsink" - yes, you did.
[9:54] <shbrngdo> until the internals of the ARM core go to a lower voltage, increases in speed are likely to require heat sink + fan or some other elaborate cooling mechanism, like heat pipes, peltier, etc.

[10:00] <shbrngdo> if you can just reduce it by a few degrees, it's probably all you need.
[10:00] <ground> 3b = it just drops to 600mhz and there's no problem. 3b plus other issues EG sdram_freq ethernet checksum offload.

[10:01] <shbrngdo> it drops to 600mhz but only when the chip reports temperature is too high. if the USB stuff is causing a 'hot spot' it may not show up as overtemp
[10:01] <shbrngdo> as I understand it, that's all done with the power management stuff
[10:02] <shbrngdo> at least, that's how it would work in FreeBSD, so it doesn't appear to be a built-in CPU feature
[10:02] <shbrngdo> "some driver" reads the temperature, "anothe driver" modulates CPU freq.

[10:40] <raulp> @BurtyB first i need to read what exactly do they do ... but i think i tried them and still my light was on
[10:43] <shbrngdo> raulp - when an IO pin is set as an output, it'll be "definitely 0" and "definitely 1" (no in betweens). I also suggest a resistor between any IO pin and an LED. you don't want to fry either one
[10:43] <shbrngdo> 200 ohms is a good ballpark series resistor value for an LED. YMMV
[10:43] <raulp> let me show you guys what i mean
[10:44] <shbrngdo> if the pin is still an input pin, only the pullup resistor will be supplying current to an LED
[10:44] <raulp> i tried all modes, still i see the light :(
[10:45] <shbrngdo> if you set that pin as an output pin, you can assign 1 or 0 to it. FYI - check the wiring diagram link I sent to you, to make sure you're using the correct GPIO number
[10:45] <shbrngdo> GPIO number is not the same as pin number.
[10:45] <shbrngdo> https://elinux.org/Rpi_Low-level_peripherals
[10:45] <raulp> right, that i know
[10:45] <raulp> let me record a video
[10:45] <raulp> can i PM you so you can see it?
[10:46] <shbrngdo> eh, I probably won't download it. I think you're just making a simple mistake someplace. try reading over the IO pin docs to make sure you're doing it right
[10:46] <raulp> you don't need to download it :) google, yt :)
[10:46] * shbrngdo observes: video = "something recording in uber-high-def video on a phone" --> me taking an hour to download it at <1Mbit
[10:46] <BurtyB> "gpio mode X down" turns an LED off for me on a pin set as an input
[10:47] <raulp> BurtyB not for me :(
[10:47] <BurtyB> (as does tri)
[10:47] <raulp> gpio read 8 = 1
[10:47] <BurtyB> which pin are you using as some (i2c pins) have pullup resistors too
[10:47] <ShapeShifter499> raulp: sorry I clicked out, yes it's the 3B+.
[10:47] <shbrngdo> yeah the gpio utility should set modes and stuff for you, also if you dump ALL pins you might see what's happening. make sure it's a pin that you CAN change mode on
[10:48] <raulp> ok, so the ones i have "issues" are: 8 9 7 30 21 22 for ex (wPi)
[10:48] <shbrngdo> gpio 8 is also used by the SPI interface, and if it's enabled, it's fighting you
[10:48] <BurtyB> raulp, if you're using wiringpi pin 8 then it has a resistor so you're not going to be able to turn that off
[10:48] <shbrngdo> see the web page I mentioned a couple of times already. it explains a few things

[10:49] <raulp> seems to me i'm confusing something here
[10:49] <raulp> and my brain can't understand why this LED is "partialy" on ... when the code says OFF :)
[10:51] <raulp> GPIO02, 03, 05 and 27 are available on S5 (the CSI interface) when a camera peripheral is not connected to that socket, and are configured by default to provide the functions SDA1, SCL1, CAM_CLK and CAM_GPIO respectively. SDA1 and SCL1 have 1K6 pull-up resistors to 3.3 V.

[10:54] <BurtyB> raulp, any reason you've got it set to input (rather than output) if you're trying to turn an led off anyway?
[10:55] <raulp> well, no, IN is default, so i thought that just connecting ... will be off
[10:55] <shbrngdo> yes you must tell the GPIO interface to change a pin into an output
[10:55] <raulp> but you are right
[10:56] <raulp> Once i say: setup OUT ... and then toggle HIGH LOW ... works as expected
[10:56] <shbrngdo> you can dump all of the pin states using the 'gpio' utility - I forget what command it is, though.

[14:44] <localhorse> I_Died_Once_: but would it work?
[14:44] <localhorse> i need something that works

[14:45] <localhorse> i was using it with ssh but i forgot my pi user password
[14:45] <localhorse> which i'm trying to reset
[14:45] <I_Died_Once_> unless its been changed, try user: pi // password: raspberry
[14:45] <localhorse> for that i need to edit cmdline.txt
[14:45] <localhorse> I_Died_Once_: ofc i tried that
[14:45] <localhorse> i tried all the passwords that it could be..
[14:46] <I_Died_Once_> have you spoke with the owner of the pi?
[14:46] <localhorse> I_Died_Once_: i am the owner
[14:46] <I_Died_Once_> why you doing jackassy stuff like losing the password
[14:46] <localhorse> I_Died_Once_: dunno, shit happens

[14:47] <localhorse> anyway, i need to edit cmdline.txt to reset the pw
[14:47] <localhorse> would it work from virtualbox with manjaro?
[14:47] <I_Died_Once_> your solution is to seek a way to change the root password for linux as a whole and not so much he rpi
[14:48] <localhorse> why?

[14:54] * markopasha (~cc@ has joined #raspberrypi
[14:54] <pksato> I think so.
[14:54] <localhorse> Shift or Shift+Up arrow ?

[15:01] <pksato> the password recover procedure works on any linux system.
[15:01] <localhorse> pksato: yes but how to also reset the root password?
[15:01] <pksato> yes.
[15:01] <localhorse> not just for user "pi"
[15:02] <pksato> passwd root and passwd pi
[15:02] <I_Died_Once_> sudo passwd root
[15:02] <localhorse> pksato: `passwd root`?
[15:02] <localhorse> ok
[15:02] <localhorse> thanks

[15:02] <I_Died_Once_> sudo passwd pi
[15:02] <pksato> not need sudo.
[15:02] <localhorse> I_Died_Once_: isnt it a root shell already?
[15:02] <pksato> or su
[15:02] <I_Died_Once_> sudo passwd yomamma

[15:30] <localhorse> CoJaBo: why?
[15:30] <immibis> i've missed this conversation - but since you can't mount it in your linux virtualbox, is it possible to copy the image off the card, edit that in your linux virtualbox, then put the modified image back on the card?

[15:31] <immibis> whatever tool you used to get the image there previously, i guess

[16:43] <TheNik> Screen or similar, that is

[16:43] <danielboston26> which is to say seperate from the pi
[16:43] <danielboston26> i did buy the rasp pi screen but haven't connected it yet
[16:43] <danielboston26> could i have a faulty board?
[16:43] <TheNik> I'm afraid that's beyond my qualification, then :/
[16:44] <danielboston26> bought it from rs components
[16:44] <Blubberbub> did you update the firmware on the sd card?
[16:44] <danielboston26> through amazon
[16:44] <Encrypt> ShorTie | each model pi requires more power // That's the reason why I like my Pi 2B :D
[16:45] <danielboston26> Blubberbub haven't done that for awhile but its up to date as of the 3 being released so it should have what it needs
[16:45] <danielboston26> Blubberbub i would say i last updated it a few weeks ago
[16:45] <Blubberbub> 3b+ needs new, i think
[16:45] <Blubberbub> new firmware files, that is
[16:45] <danielboston26> Blubberbub so should i use the 2 to download an update or make a new image?
[16:46] <Blubberbub> either way works
[16:46] <Blubberbub> i'd use the 23

[16:47] <danielboston26> i do have other usb power supplies i can try
[16:47] <danielboston26> i can plug in an apple one that should give it more then it needs
[16:48] <danielboston26> i do have another sd card i could try but its not giving me that type of error
[16:50] <danielboston26> hmmm so it does seem this might be firmware releated
[16:51] <danielboston26> although as its the same spec im not sure why older firmware wouldn't tell the pi to use more power
[16:51] <danielboston26> and why it worked on a 2 and not a 3
[16:51] <mfa298> danielboston26: the 3B+ needs an image from at least March this year - Earlier images won't have all the required bits to start it up. If you had a stretch image without using NOOBs then apt-get upgrade would get the right firmware.
[16:51] <danielboston26> mfa298 what if i used noobs?
[16:51] <mfa298> but if it's Jessie and/or you used noobs apt-get won't get all the bits you need (so starting with a clean image might be easier)
[16:52] <danielboston26> mfa298 ah that might be the issue
[16:52] <danielboston26> mfa298 i can create a new image
[16:52] <danielboston26> mfa298 i just used noobs because it was faster
[16:52] <mfa298> there might be a way to update noobs, but I don't know what it is (as I don't use noobs)
[16:53] <danielboston26> mfa298 i believe there is a update firmware command
[16:53] <danielboston26> but its not reccomended
[16:53] <danielboston26> but i shall try making a new image
[16:54] <danielboston26> perhaps the devs should make an error saying update firmware not showing an irrelevant error about power

[17:04] <danielboston26> the only time you need to edit the config file is if your using the cli
[17:04] <danielboston26> TheNik then you should be able to enable if

[17:04] <danielboston26> have you go into raspberry pi config and enabled wifi?

[17:05] <danielboston26> i believe its under preferances if im not mistaken
[17:05] <TheNik> I don't think I have this option there in the GUI. In what tab should it be?

[17:07] <danielboston26> im trying to find screenshots so i can walk you through it
[17:07] <danielboston26> as i can't boot my pi
[17:08] <TheNik> I did just do that. I have Network Options there, but when I select the "Wi-Fi" setting, it says "No wireless interface found"
[17:08] <localhorse> when i do `mount -o remount, rw /` i get "mount: /: mount failed: Unknown error -1", why? following this guide https://howtoraspberrypi.com/recover-password-raspberry-pi/
[17:08] <TheNik> I'm pretty sure the issue lies deeper, because ifconfig -a does not return the wlan0 interface at all
[17:09] <Blubberbub> localhorse, the space before rw is wrong
[17:09] <danielboston26> hmmm
[17:09] <danielboston26> TheNik do you have a pi 3?

[17:09] <localhorse> Blubberbub: thanks so much!
[17:09] <Blubberbub> TheNik, if it is not enabled in /boot/config it might not show up as an interface
[17:10] <Blubberbub> i think
[17:10] <localhorse> now it works, i could reset the pi's password
[17:10] <localhorse> Blubberbub: btw, what's the default pw for root user?
[17:10] <danielboston26> raspberry i believe
[17:10] <localhorse> that's for user "pi"
[17:10] <localhorse> also for user root?
[17:11] <danielboston26> there is no root password by default
[17:12] <danielboston26> root should be disabled
[17:12] <danielboston26> when you enable it it will ask you to enter a password
[17:12] <danielboston26> you can change it with the pw command
[17:12] <danielboston26> that is if you remember what you make it in the first place
[17:12] <danielboston26> im assuming you want to change it because you forgot it
[17:13] <danielboston26> TheNik sounds like either a hardware fault or your missing a driver that may be a noob issue
[17:13] <danielboston26> burning a new image with etcher or rufus should fix that
[17:13] <TheNik> I may try re-installing Raspbian with NOOBS, if that could help
[17:14] <danielboston26> TheNik noobs might not have the wifi driver

[17:15] <localhorse> Blubberbub: i'm booted into the pi, how can i edit cmdline.txt from there?

[17:21] <TheNik> Ah, because I only used apt-get so far.
[17:21] <danielboston26> eh it shouldn't matter
[17:21] <TheNik> Is the difference long/difficult to explain?
[17:21] <danielboston26> apt is the newer version
[17:21] <danielboston26> the wikipedia article gives a nice explination of the differences
[17:21] <TheNik> Ah, I see. Thanks, I'll read that up
[17:22] <danielboston26> but one of the nice things apt does is it gives you a progress bar
[17:22] <danielboston26> instead of you just staring at a blank screen and wondering whats happening
[17:22] * indy (~indy@dsl-static-104.213-160-167.telecom.sk) has joined #raspberrypi

[17:22] <danielboston26> TheNik
[17:23] <danielboston26> but both apt and apt-get do foundamentally the same thing while doing it differently if that makes sense
[17:23] <danielboston26> apt is what will be used going forward
[17:23] <TheNik> I only ran apt upgrade, it's not done yet
[17:23] <danielboston26> ok
[17:24] <danielboston26> do apt upgrade dist after it runs but it should tell you if there was something that couldn't be upgraded without running dist
[17:24] <TheNik> It might be useless if they do the same, but it's worth a try
[17:25] <danielboston26> apt upgrade and apt upgrade dist do not do the same thing
[17:25] <TheNik> I mean running the apt command rather than apt-get
[17:25] * sigsts (~sigsts@unaffiliated/skyroverr) has joined #raspberrypi
[17:25] <danielboston26> ah ok
[17:25] <danielboston26> ya theres no difference in what they do
[17:26] <danielboston26> but the fact that upgrade is still running tells me its doing something
[17:26] <TheNik> I am, unfortunately, not knowledgeable at all in the Linux system, so I might be ignorant of important things
[17:26] <danielboston26> so im gussing your horribly out of date
[17:26] <TheNik> I just hope the chip is not broken ;-)
[17:26] <danielboston26> im gussing you have an out of date driver
[17:27] <TheNik> Hopefully
[17:27] <danielboston26> just keep running apt till it says theres no more updates
[17:27] <danielboston26> apt should download everything you need at once
[17:27] <danielboston26> thats another advantage over apt-get
[17:28] <TheNik> After apt upgrade, I should try apt upgrade dist?
[17:28] <danielboston26> if will handle dependances
[17:28] <danielboston26> it won't hurt anything
[17:28] <TheNik> Oh, hey, I see an ASCII progress bar. That's cool! :D
[17:28] <danielboston26> does it say anything wasn't upgraded that should of been?
[17:29] <TheNik> It's not done yet. I'm not sure how long it needs, either, because that's not the first progress percent number I see, and it might not be the last
[17:29] <danielboston26> let it run till its done
[17:29] <danielboston26> in your case you needed apt
[17:29] <TheNik> Yeah, I have time
[17:30] * sigsts (~sigsts@unaffiliated/skyroverr) Quit (Remote host closed the connection)
[17:30] <danielboston26> apt-get was leaving packages unupgraded because of dependancies

[17:30] <TheNik> That might be the difference, yes
[17:30] <TheNik> Though, the image was downloaded and burned today
[17:31] <danielboston26> you may also need to run dist
[17:31] <danielboston26> but it will tell you if you need to
[17:31] <danielboston26> also it doesn't hurt anything to run it
[17:31] <danielboston26> and always make sure you run apt update before apt upgrade
[17:32] <TheNik> Well, that's too late now, because I only ran apt upgrade

[17:34] <jancoow> so; when using a pi as bluetooth audio player it works fine
[17:35] <TheNik> Okay, I'll do that
[17:35] <jancoow> But can I also send seria lcommando's to the device?
[17:35] <jancoow> so both audio and serial commands?
[17:35] <danielboston26> upgrade will tell you if anything couldn't be updated
[17:35] <danielboston26> if there are packages that could not be updated that is when you use dist but it doesn't hurt anything to run it anyway
[17:36] <TheNik> What does apt upgrade dist do that apt upgrade does not?
[17:36] <danielboston26> sometimes there are packages that upgrade can't or won't upgrade
[17:36] <TheNik> Okay
[17:37] <TheNik> Okay, so apt upgrade finished, I ran apt update, re-ran apt upgrade, nothing happened. I'll now try apt upgrade dist
[17:37] <danielboston26> dist-upgrade
[17:37] <danielboston26> dist-upgrade in addition to performing the function of upgrade,
[17:37] <danielboston26> also intelligently handles changing dependencies with new versions
[17:37] <danielboston26> of packages; apt-get has a "smart" conflict resolution system, and
[17:37] <danielboston26> it will attempt to upgrade the most important packages at the
[17:37] <danielboston26> expense of less important ones if necessary. So, dist-upgrade
[17:37] <danielboston26> command may remove some packages. The /etc/apt/sources.list file
[17:37] <danielboston26> contains a list of locations from which to retrieve desired package
[17:37] <danielboston26> files. See also apt_preferences(5) for a mechanism for overriding
[17:37] <danielboston26> the general settings for individual packages.
[17:38] <danielboston26> apt handles a lot of what dist is suppose to do
[17:38] <danielboston26> but ive seen times where dist will upgrade stuff that apt won't
[17:39] <TheNik> Okay, apt upgrade dist did a bit of stuff and finished too. Let me try rebooting and connecting to WLAN anew.

[17:39] <danielboston26> if it doesn't work try running apt update again and see if it finds anything
[17:40] <danielboston26> also it will tell you what it is updating so you can look and see if it says anything about wifi
[17:40] <danielboston26> there is a command that will tell you all of the updates if finds but i can't remember it off the top of my head
[17:40] <localhorse> Blubberbub: wtf: i reset my pi passwd to "raspberry" but now when i try to log in via ssh, it says "wrong password", how can that be?
[17:40] <danielboston26> if you run man apt it will give you the man page
[17:41] <danielboston26> localhorse check ssh config and make sure you didn't hardcode your old password
[17:41] <danielboston26> also make sure it isn't hardcoded on your client
[17:41] <danielboston26> that happened to me
[17:41] <localhorse> danielboston26: which client? i typed it in
[17:42] <danielboston26> what are you using to ssh into your pi
[17:42] <localhorse> danielboston26: and which config? .ssh/whatfile?
[17:42] <danielboston26> that is the client
[17:42] <localhorse> danielboston26: ssh on the cmd line
[17:42] <danielboston26> on another pi? or linux machine?
[17:42] * Frank (~FrankGoul@ has joined #raspberrypi
[17:42] <localhorse> danielboston26: windows
[17:42] <danielboston26> you have ssh installed on windows?
[17:42] <localhorse> yes
[17:43] <localhorse> from git
[17:43] <danielboston26> ok
[17:43] <localhorse> it used to work to connect to the pi via ssh
[17:43] <TheNik> It did not immediately work, but I'll have another look at what I can do
[17:43] <danielboston26> run apt update again
[17:44] <danielboston26> localhorse im not sure where git puts ssh on windows
[17:44] <localhorse> danielboston26: it doesn't matter
[17:44] <localhorse> i typed in the pw
[17:44] <danielboston26> it does matter because thats where your config file lives
[17:44] <danielboston26> so it may say this is your password
[17:45] <localhorse> danielboston26: http://pastebin.centos.org/807826/27954299/
[17:45] <danielboston26> and when you type in the new password ssh looks at the file and says no thats not right
[17:45] <localhorse> danielboston26: does the error say anything?
[17:45] <danielboston26> ok that error is different from an inncorect password
[17:45] <danielboston26> you setup a keypaid?
[17:46] <TheNik> apt update first returns two "hits" and then reports that all packages are up to date. I can re-run it indefinitely, it still gets two hits
[17:46] <localhorse> danielboston26: it stores stuff in C:\Users\me\.ssh but there is no config file. what should its name be?
[17:46] <localhorse> danielboston26: keypaid?
[17:46] <danielboston26> TheNik what does it say?
[17:46] <danielboston26> keypair*
[17:46] <TheNik> Where?
[17:47] <TheNik> The two hits, you mean?
[17:47] <danielboston26> yes
[17:47] <localhorse> danielboston26: yes but it asked for my pw for user "pi"

[17:48] <TheNik> "http://raspbian.raspberrypi.org/raspbian stretch InRelease" and "http://archive.raspberrypi.org/debian stretch inRelease"
[17:48] <danielboston26> you also need to have your private key otherwise the password won't work
[17:48] <localhorse> haven't used the pi in like 8 months
[17:48] <localhorse> danielboston26: i have my priv key
[17:48] <localhorse> danielboston26: but why is the pw not working?
[17:48] <localhorse> for user "pi"
[17:48] <danielboston26> because it cannot file your private key
[17:49] * Gathis (~TheBlack@unaffiliated/gathis) has joined #raspberrypi

[17:49] <danielboston26> if you setup a keypair you need your password PLUS your private key your password may be correct but it cannot find your private key
[17:49] <danielboston26> also your private key might be using your old password
[17:49] <danielboston26> i would generate a new one
[17:49] <localhorse> danielboston26: why does it need my private key to allow me to login with username+password?
[17:49] <localhorse> my priv key has no pw
[17:49] <localhorse> it asked for pw for user "pi"
[17:50] <danielboston26> localhorse because you set it up that way
[17:50] <localhorse> i only have these files, no file named "config" https://prnt.sc/jpy9l3

[17:50] <danielboston26> the config file will be on the server
[17:50] <localhorse> it asked for pw for user "pi"
[17:50] <danielboston26> right but you also need the private key to login if you created a key pair
[17:51] <localhorse> danielboston26: isnt it always still possible to login with only username and pw?
[17:51] <danielboston26> TheNik can you take a screenshot of whats being displayed and send it to me?
[17:51] <danielboston26> localhorse not if you tell it to use a keypair
[17:51] <localhorse> danielboston26: so on the pi i have to check /home/pi/.ssh/config ?
[17:51] <danielboston26> yes
[17:52] <danielboston26> see how you have it setup
[17:52] <danielboston26> you can also disable and reenable ssh
[17:52] <danielboston26> that should clear any changes you made
[17:52] <localhorse> danielboston26: " not if you tell it to use a keypair" is this setting for any ssh connection attempts for user "pi"? or only from a specific ip?
[17:53] <localhorse> danielboston26: how should i disable/reenable ssh?

[17:56] <danielboston26> that will reload all the defaults
[17:56] <localhorse> danielboston26: there is also no config file in /home/pi/.ssh
[17:56] <TheNik> danielboston26: https://i.imgur.com/MNN76Lx.png
[17:57] <localhorse> danielboston26: i cant reformat, i need to keep the data as it is!!!!
[17:57] <danielboston26> TheNik ah ok i see what your saying
[17:57] <danielboston26> thats just telling you what its checking
[17:57] <TheNik> Ah, okay
[17:57] <danielboston26> you can add different sources for packages
[17:58] <danielboston26> so your all up to date
[17:58] <danielboston26> if wifi is still not working it maybe a hardware issue
[17:58] <danielboston26> is this a new board?
[17:59] <TheNik> It's not very new, but I have not used it much. And last time I used it, WLAN connection was working
[17:59] <danielboston26> ok thats another indicator of hardware failure
[17:59] <danielboston26> you can get a external wifi adapter
[17:59] <TheNik> Aww :-(
[18:00] <danielboston26> that will work fine
[18:00] <danielboston26> who did you buy this from?
[18:00] <TheNik> As a last resort, Raspberry Pi boards are open source IIRC? How dangerous would it be to try and physically replace the WiFi chip?
[18:00] <danielboston26> theres very few authorized dealers for the raspberry pi
[18:01] <danielboston26> TheNik as i said an external wifi adapter will work

[18:03] <danielboston26> and those have issues
[18:03] <danielboston26> did you pay anything less then 35 dollars for it?
[18:04] <danielboston26> like you didn't get a raspberry pi 3 for 10 bucks?
[18:04] <SpeedEvil> There are no knockoff PIs.
[18:04] <SpeedEvil> AIUI
[18:04] <TheNik> I don't think it was suspiciously cheap, no
[18:04] <SpeedEvil> Pretty much because they can't get the broadcomm parts
[18:05] <danielboston26> SpeedEvil correct but ive seen pi's being sold for under 35 bucks
[18:05] <danielboston26> so that seems to indicate they are either knock off or someone got a really good deal
[18:05] <danielboston26> SpeedEvil do you really think thats going to stop a chinese counterfieter?
[18:07] <danielboston26> TheNik you shouldn't of paid anything less then 35 dollars for a pi
[18:07] <mfa298> danielboston26: if it's got a broadcom chip and it's cheap it's either 2nd hand or a good deal. or it's using a different chip so won't boot a normal raspberry Pi image.
[18:07] <TheNik> As I said, I don't remember how much it was
[18:08] <danielboston26> TheNik to answer your other question if your good at soldering you can desolder the smt wifi chip and resolder a new one
[18:08] <mfa298> the Broadcom SoCs (used by the Pi) and Alwinner SoCs (used by most of the cheap Chinese firms) are very differnt in how they boot.
[18:08] <danielboston26> mfa298 i see
[18:08] <danielboston26> i never investigated them but i do know they exist
[18:08] <TheNik> The WiFi chip is not tied to this specific device or anything? It will work with a different chip, provided I manage to solder it?
[18:09] <danielboston26> TheNik i believe the wifi chip is open source
[18:09] <TheNik> No, I mean a different similar chip. Same model, but not this exact chip, but a replacement
[18:10] <danielboston26> well you would have to use the same chip the rasp pi foundation uses or write your own driver for it
[18:10] <danielboston26> or somehow get a driver
[18:10] * borkr (~borkr@static130-244.mimer.net) has joined #raspberrypi
[18:10] <danielboston26> but it uses a broadcom chip which are not open source
[18:10] <TheNik> I'd order the chip with my next bunch of parts
[18:11] <mfa298> TheNik: I've not read all the scroll back (there's way to much) but if you don't know if the issue is hardware or something else get a spare SD card and try putting the latest image on it. If it works the hardware is good, if it fails then the hardware is suspect
[18:11] <danielboston26> mfa298 we have tried running updates and he tried burning a new image

[18:12] <danielboston26> mfa298 wifi did work at one point
[18:12] <danielboston26> which is why i was suspecting a cheap knockoff that failed
[18:12] <TheNik> mfa298: I burned a news Raspbian stretch without NOOBS, and ran updates as instructed by danielboston26. WiFi used to work indeed, and stopped, which led me to reinstall the system.
[18:13] <danielboston26> mfa298 if you have more detailed knowledge of how the pi uses wifi be my guest to take over
[18:13] <danielboston26> but at this point im suspecting hardware
[18:14] <danielboston26> TheNik did you overclock your pi or was it running very hot?

[18:14] <danielboston26> i know the 3s can run hot
[18:14] <danielboston26> heat will cause parts to fail
[18:14] <mfa298> if it doesn't work with a clean and recent raspbian release then that's probably hardware, wlan ought to be there by default with a recent raspbian image.
[18:15] <TheNik> I didn't overclock it, and to the touch it feels pretty hot on occasion. The temperature the Raspberry Pi returns never went above 50 degrees, though. Usually just 43 - 44, once it was 47.
[18:15] <danielboston26> however i see from your screenshot that bluetooth is working and that is on the same chip so that puzzels me
[18:15] <TheNik> I have a bluetooth keyboard for it and it's fine
[18:15] <TheNik> But it seems to fail to find the wlan0 interface
[18:15] <danielboston26> that is very odd
[18:16] <danielboston26> that makes it sound like a software issue
[18:16] <danielboston26> but what would cause wlan to suddenly stop working

[18:17] <danielboston26> are you able to use wifi on other devices?

[18:19] <danielboston26> ok
[18:19] <danielboston26> so your wifi is working

[18:20] <danielboston26> run ifconfig
[18:20] <danielboston26> what does it say under wlan0
[18:20] <TheNik> ifconfig -a finds no wlan0
[18:21] <danielboston26> that is odd
[18:21] <danielboston26> when you made a new image did you totally reformat the card?

[18:22] <TheNik> I relied on etcher bruning the image. I think it should reformat the card
[18:22] <danielboston26> i wouldn't assume that
[18:22] <danielboston26> i would reformat it via windows first
[18:22] <TheNik> Downloaded Raspbian from https://downloads.raspberrypi.org/raspbian_latest

[18:30] <localhorse> i have ethernet plugged in
[18:30] <localhorse> wlan0 is part of the pi
[18:30] <danielboston26> no i mean is there a cable plugged into the ethernet port?
[18:30] <localhorse> when i plug in ethernet, it cant get internet access

[18:35] <AppAraat> anyone here knows how long on average the first boot takes on a RPi ZW with a 16GB SD card (c10)?
[18:35] <AppAraat> (Volumio)
[18:35] <danielboston26> on ubuntu theres a check mark to say only use ethernet for lan devices
[18:35] * orti (~orti@p54A62149.dip0.t-ipconnect.de) has joined #raspberrypi
[18:35] <localhorse> checkmark?
[18:35] <danielboston26> so you can use ubuntu on your pi if you need that setting
[18:35] <TheNik> danielboston26: Do you advise re-downloading the Raspbian image or can I reuse the same file? It's not hard to do, but it takes 10 - 20 minutes extra
[18:36] <localhorse> danielboston26: no, i need to preserve the current install
[18:36] <danielboston26> it shouldn't matter
[18:36] <danielboston26> ok
[18:36] <TheNik> Okay, I'll use the same

[18:37] <danielboston26> localhorse this might be a question for the raspbian channel
[18:37] <localhorse> danielboston26: which network settings?
[18:37] <danielboston26> they will know what settings are avaliable
[18:37] <localhorse> i use ssh, no screen
[18:38] <danielboston26> oh
[18:38] <danielboston26> thats right
[18:38] * vikaton (uid59278@gateway/web/irccloud.com/x-ckflveyfexkonvbj) has joined #raspberrypi
[18:38] <danielboston26> can you access the pi directly?
[18:38] <localhorse> yes
[18:38] * pavlushka (~pavlushka@ubuntu/member/pavlushka) has joined #raspberrypi
[18:38] <danielboston26> i would do that
[18:38] <TheNik> After fromatting the SD card, it only has 49 MB of memory. The formatting does not fully remove the burned partitions and whatnot
[18:38] <BurtyB> sounds like you've either got them both in the same subnet or you have an extra default route you don't want
[18:39] <danielboston26> check both rasp-config and the gui
[18:39] <localhorse> Blubberbub: me?
[18:39] <danielboston26> BurtyB he uses ethernet for lan
[18:39] <localhorse> BurtyB: me?
[18:39] <danielboston26> BurtyB we are looking for a setting to set ethernet for lan devices only
[18:39] <danielboston26> there is such a setting in ubuntu
[18:40] <danielboston26> im not sure if thats something they added or if its a debian setting
[18:40] <BurtyB> localhorse, yes
[18:40] <danielboston26> if its a debian setting then raspbian should have it

[18:41] * sigsts (~sigsts@unaffiliated/skyroverr) Quit (Remote host closed the connection)
[18:41] <BurtyB> localhorse, "ifconfig -a" should show if you ahve the same subnet on both devices and "ip route" will show you the routes
[18:41] <localhorse> BurtyB: thx, and how to edit the routes?
[18:42] <danielboston26> BurtyB it sounds like its prioritizing ethernet over wifi
[18:42] <BurtyB> danielboston26, that would be expected
[18:42] <danielboston26> i was trying to see if theres a setting to tell it not to do that or only use ethernet on the lan
[18:42] <danielboston26> BurtyB correct
[18:42] <danielboston26> ubuntu has such a setting
[18:43] <localhorse> BurtyB: is danielboston26 right that it should be able to figure out that ethernet has no internet access and then use wifi for internet?
[18:43] <localhorse> or is it not smart enough?
[18:43] * danielboston26 (~markbosto@unaffiliated/danielboston26) Quit ()
[18:43] <mfa298> localhorse: don't set a default route (default gateway) on eth0 (of if you're getting that address via DHCP set the dhcp server not to offer a default gateway
[18:44] <localhorse> mfa298: i have to do it independently of the dhcp server

[18:44] <danielboston26> that was odd
[18:44] <danielboston26> i removed my sd card from my computer and irc went dead
[18:44] <danielboston26> :P
[18:45] <BurtyB> localhorse, you could try altering the metric but it really depends how you have everything setup as to if that would work
[18:45] <localhorse> BurtyB: ok, how can i change the metric? it worked for my windows laptop
[18:45] <mfa298> the default router/gateway setting (whether via dhcp or manually configured) is what tells the pi to use that interface for internet traffic (it's the default gateway if it doesn't know how else to get to a network)
[18:46] <I_Died_Once_> localhorse... how did your issue go from.. need to edit the cmdline.txt because you forgot your password.... to needing to install a dhcp server...?
[18:46] <TheNik> Okay, I formatted and re-partitioned the SD card to regular Windows compatible standard. There is definitely no Raspbian left on it anymore
[18:46] <localhorse> mfa298: but i want the pi to ignore what the router tells it and just use wlan0 for internet
[18:46] <localhorse> I_Died_Once_: no
[18:47] <I_Died_Once_> what kind of left handed nonsense are you involved in?
[18:47] <BurtyB> localhorse, iirc you can set the metric in dhcpcd.conf but again it depends how you have everything else setup
[18:47] <localhorse> I_Died_Once_: i need to tell the pi to use wlan0 for internet, not ethernet
[18:47] <mfa298> localhorse: if it's getting the address via DHCP then there might be an option on the DHCP client to tell it not to use the gateway.
[18:47] <localhorse> BurtyB: thx
[18:47] <localhorse> btw, now i put another pi on my network instead, and when trying to ssh into it, i get " WARNING: POSSIBLE DNS SPOOFING DETECTED!" how can i force it?
[18:47] <danielboston26> I_Died_Once_ i helped him with his password
[18:47] <danielboston26> his ssh server got messed up so disabling and reenabling it fixed that problem
[18:48] <I_Died_Once_> ...disconnect the ethernet?

[18:52] <localhorse> would you recommend cross compiling in vbox?

[18:53] <Fulgen> localhorse: https://archlinuxarm.org/wiki/Distcc_Cross-Compiling
[18:53] <mfa298> depends what your building. Cross compiling might be faster to do the compile but might take a long time to get setup.

[21:21] <jonaslund> hmmm
[21:21] <jonaslund> no wlan definetly
[21:22] <shbrngdo> does that ip utility display inactive interfaces? I know ifconfig will - "ifconfig wlan0" to see if the device is being detected
[21:22] <TheNik> I am currently tethering my Android phone and the Raspberry Pi to provide it internet access, but that's a short term solution. As was established previously, it might be a hardware failure because the wlan stopped working after a period of not using it, however, Bluetooth still works
[21:23] * cave (~various@h081217094244.dyn.cm.kabsi.at) Quit (Remote host closed the connection)
[21:23] <shbrngdo> TheNik - does a reboot bring it back, or is it just dead?
[21:23] <TheNik> "ifconfig wlan0" returns "Device not found"
[21:23] <TheNik> shbrngdo: It's just dead :-(
[21:23] <jonaslund> shbrngdo: it should i think, i'm pretty sure i used that a few hours ago before setting the wlan up
[21:23] <shbrngdo> I have to wonder if 'lsmod' or 'lsusb' might also help, to see what's being detected and what modules loaded
[21:23] * jonaslund is running the debian arm64 preview
[21:24] <jonaslund> (no ifconfig command there)
[21:24] <shbrngdo> that's just BOGUS
[21:24] <BurtyB> shbrngdo, you'll need "ifconfig -a wlan0" to show down interfaces too
[21:24] <BurtyB> iirc?
[21:25] <TheNik> lsusb lists my phone, an ethernet adapter, an SMC9514 Hub (?) and a root hub.
[21:25] <TheNik> lsmod lists more than I could even fit in a single screenshot.

[21:27] <shbrngdo> BurtyB - yeah that's right - on freebsd, '-a' means something else
[21:27] <TheNik> Here is the lsmod output: https://pastebin.com/N8cZXSJK
[21:28] <TheNik> I suppose rndis_wlan is not related to what I am looking for?

[21:29] <shbrngdo> as far as I can tell the rndis_wlan driver is the one you want loaded [I don't have an RPi 3 to compare with, someone else might]
[21:29] <jonaslund> checking on mine, can't really see what driver is used
[21:29] <shbrngdo> what does 'lsusb' tell you? [I think wlan uses USB]

[21:31] <TheNik> As I said, only my phone, ethernet adapter, SMC9514 hub, whatever that is, and a root hub. Interestingly, it has device numbers 1, 2, 3 and 5, 4 is missing
[21:32] * borkr (~borkr@static130-244.mimer.net) Quit (Ping timeout: 240 seconds)
[21:32] <TheNik> Ah, at this point it's 1, 2, 3 and 8 even. 8 / 5 being my phone.
[21:32] <JessicaRN> shbrngdo: it cant locate mplayer when I do "sudo apt-get install mplayer"
[21:32] <shbrngdo> ok that's significant then. check dmesg output and /var/log/messages and things like that for USB errors. it might tell you something
[21:33] <TheNik> What, approximately, should I be looking for?
[21:33] <shbrngdo> JessicaRN - you probably need to enable 'non-free' and 'contrib' in your repo list for apt
[21:33] <JessicaRN> shbrngdo: how do I do that?
[21:34] <jonaslund> bcm2708_fb.fbwidth=656 bcm2708_fb.fbheight=416 bcm2708_fb.fbswap=1 dma.dmachans=0x7f35 bcm2709.boardrev=0xa02082 bcm2709.serial=0x6f3dd72 bcm2709.uart_clock=48000000 smsc95xx.macaddr=B8:27:EB
[21:34] <shbrngdo> in "/etc/apt/sources.list" add the words "contrib" and "non-free" (no quotes) to the end of the lines where you see things like 'main' and 'security'
[21:34] <jonaslund> <- that should be the wifi device ?
[21:36] <shbrngdo> the mac addr has something to do with mac address randomization, which I think is the *WORST* thing ever thought up [it screws up my dhcp daemon and the hook with DNS]
[21:36] <shbrngdo> probably
[21:36] <JessicaRN> shbrngdo: should this work? "sudo apt-add-repository contrib"
[21:36] <shbrngdo> dunno - that's a feature I'm not familiar with. I just hand edit 'sources.list'
[21:37] <jonaslund> sorry.. that was the eth0
[21:37] <shbrngdo> but you want 'non-free' as well
[21:37] <jonaslund> hmmm
[21:37] <jonaslund> syslog mostly shows eth0
[21:37] <shbrngdo> you want to look for USB errors if they're showing up
[21:38] * yohnnyjoe (~yohnnyjoe@c-73-129-2-10.hsd1.dc.comcast.net) has joined #raspberrypi
[21:38] <jonaslund> oh mine works
[21:38] <shbrngdo> if the reason for failure is a bad wifi adaptor, then you might see USB errors [why '4' is missing in the sequence, it failed detect/startup ]
[21:38] <jonaslund> trying to find what device to look for
[21:38] <shbrngdo> I see
[21:38] <shbrngdo> lsusb should tell you the device stuff
[21:39] <jonaslund> not installed
[21:39] <shbrngdo> as I recall it even tells you the driver if you want it to [I don't have any usb's plugged into my linux box at the moment]
[21:39] <jonaslund> (running debian buster arm64 preview)
[21:40] <shbrngdo> 'buster' huh? yeah I've got devuan running on my linux box, which is a jessie fork at the moment. NO SYSTEMD!!!
[21:40] <shbrngdo> but everything else is more or less the same. I bet they don't kill off 'ifconfig' either
[21:40] <shbrngdo> but if they include 'ip' tools alongside, that's fine with me
[21:41] <shbrngdo> but in any case all of the commands [and the man pages] should be close enough to reference for raspbian
[21:41] <jonaslund> shbrngdo: was choosing between devuan and this preview but went for the debian since there was some warning about the filesystem tools being outdated
[21:41] <shbrngdo> 'outdated' = "not 'modern'" where 'modern' is the "smug" definition
[21:41] <javi404> jonaslund: lsusb -t
[21:42] <TheNik> I don't think I found anything in those log files. On the other hand, I have literally no idea what I need to look for, so I might have missed it... Am I correct not to look at log entries past 20 or so seconds after boot?

[21:43] <shbrngdo> jonaslund - that's very unusual. is it in a /*/sbin directory where it's not in the path?
[21:43] <shbrngdo> lsusb is like a VERY basic command line tool, something I'd rely on being there
[21:44] * Colti (Miramar-FL@unaffiliated/colti) has joined #raspberrypi
[21:44] <shbrngdo> default users often don't have the /*/sbin directories in the default PATH - I always modify .bashrc to include them

[21:45] <TheNik> "BCM2708FB: allocated DMA memory <hex>" -> The chip seems to be alive, right?
[21:45] <jonaslund> shbrngdo: no lsusb binary in /sbin
[21:45] <caelius> Question: I have a Pi 3 B running the latest Raspbian. On about 75% of boots, eth0 doesn't get an IP address. The interface has to be bounced with 'ip link set down/up eth0' which USUALLY makes it work. I have static configured in dhcpcd.conf. How can I fix this?
[21:45] <jonaslund> TheNik: actually that FB chip might be some other
[21:46] <shbrngdo> try /usr/sbin

[21:46] <jonaslund> nope
[21:47] <TheNik> jonaslund: Well, I mean, WLAN conncections did use to work, so it must be possible to work with it software-wise. Provided it's not dead.
[21:47] <shbrngdo> caelius - I was unaware of 'dhcpcd.conf' being needed for this. check what's set in /etc/network/interfaces
[21:48] <javi404> jonaslund: ah, that won't help then.
[21:48] <shbrngdo> unless "someone changd the rules" again and I wasn't on the notification list - my devuan box is using /etc/network/interfaces
[21:48] <caelius> This is the newest Stretch. I have read things that say that you shouldn't mess with /etc/network/interfaces any more.
[21:48] * Damni (~daniele@host169-73-dynamic.24-79-r.retail.telecomitalia.it) Quit (Quit: WeeChat 2.1)
[21:48] <caelius> I'd be more than happy to disable dhcpcd and do it all in interface.
[21:48] <shbrngdo> caelius - ugh, why am I _*NOT*_ surpised!!
[21:48] <caelius> *interfaces
[21:48] <javi404> jonaslund: very strange, I don't remember ever having a system that didn't have lsusb
[21:48] <caelius> Because less is better and this is just a static IP.
[21:49] <javi404> jonaslund: find / | grep lsusb
[21:49] <shbrngdo> normally I'd just mark it as 'static' in interfaces... that's bone-headed simple, why mess that up?
[21:49] <caelius> It just did it again. I restarted it three times (i.e. shutdown -h, unplug power, wait 10s, plug in, watch boot)
[21:49] <jonaslund> javi404: well either it's due to being a preview or maybe it's some regrouping of utils in new linux kernels
[21:49] <genr8_> lsusb isnt on FreeBSD
[21:49] <caelius> Two times it worked. The third time it didn't.
[21:49] <javi404> jonaslund: could be, beaats me.
[21:49] <javi404> genr8_: wish it was honestly
[21:49] <caelius> I bounced the interface from the console and it came up.
[21:50] <shbrngdo> caelius - well, I'd give the 'interfaces' method a try, don't even bother with the DHCP stuff
[21:50] <caelius> I do notice that IPv6 is being configured first, before the IPv4 address. Maybe something is happening there?
[21:50] <javi404> genr8_: is that what they are using, a freebsd port?
[21:50] <caelius> I have another Pi that doesn't seem to have this problem.
[21:50] <caelius> And this is a fresh install, done 2 days ago

[21:54] <shbrngdo> caelius - more changes for the sake of change. WHY am I _*NOT*_ surprised! OK what I'd do then is do an 'ifconfig' (or whatever else is available, 'ip somethign' I guess) to list all of your interface names
[21:55] <shbrngdo> then put the right one in the interfaces file, then place my thumb squarely on the end of my nose, extend my fingers, and stick out my tongue
[21:55] <caelius> Wait. Wait.....could it be? Did I make an error?
[21:55] <caelius> Let's see. I think I messed up when I edited dhcpcd.conf
[21:55] <shbrngdo> heh - that'd do itr
[21:55] <genr8_> there would be errors in the dhcpd log
[21:55] <caelius> I had set up a static IP, but I accidentally commented out the interface line
[21:56] <shbrngdo> stupid 'change the rules because some smug "developer" "felt" nonsense' backfires, screws up people who've been doing it "the classic way" forEVAR

[22:01] <genr8_> IP address conflict man ?
[22:01] <caelius> Nope
[22:01] <caelius> It actually sees carrier up, sets up the addresses, then carrier down happens and it deletes them all.
[22:02] <caelius> Then carrier up, it probes the address, then carrier goes down again
[22:02] <genr8_> you should be able to have some pings go through during this cycling.... do they ?

[22:02] <shbrngdo> TheNik - I think I found the problem, here: "usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0" the device's IDs are messed up. probably broken. might need replacing.
[22:02] <genr8_> Check this : http://manpages.ubuntu.com/manpages/trusty/man8/dhcpcd-run-hooks.8.html
[22:02] * minionofgozer_ (~minionofg@ has joined #raspberrypi
[22:03] <genr8_> You may have some old hooks in that conflict or something
[22:03] <TheNik> Aww, shame
[22:03] <shbrngdo> TheNik - you could also check to see if there is anything physically wrong with the board that might indicate a short between 2 wires, especially in the area of the wifi thingy
[22:03] <genr8_> though i know nothing about DHCP hooks and first time ive heard
[22:03] <caelius> If I simply do "ip link set down eth0" then immediately "ip link set up eth0" it comes right up and is pingable
[22:03] <TheNik> I was considering to re-solder the wifi chip.
[22:03] <caelius> I even tried doing that in the rc.local, but it didn't help
[22:03] <TheNik> That is, replace it
[22:03] <shbrngdo> TheNik - otherwise, you apparently have a bad wifi
[22:04] <TheNik> What's indeed weird is the fact that bluetooth works
[22:04] <caelius> This is a completely fresh install of Stretch, recently downloaded and installed 2 days ago.
[22:04] <shbrngdo> TheNik - bluetooth is a different aminal. as I understand, it uses the serial port and not the USB bus
[22:04] <TheNik> So the USB interface of the chip might be broken somehow?
[22:05] <TheNik> The ID part? (Apologies, I have no idea how USB works)
[22:05] * BeamWatcher (~gashead76@ has joined #raspberrypi
[22:05] <shbrngdo> TheNik - when the USB queries a device, it assigns it a number (in this case appears to be 4) then queries info like the 3 strings mentioned - manufacturer, product, and serial #
[22:05] <caelius> If it's not the Ethernet interface on this Pi, maybe my router is freaking out or something. But I haven't had a problem before.
[22:05] <caelius> OK. There. It faile
[22:05] <shbrngdo> it uses this information, along with a description of the interface classes it supports, to pick a driver for it
[22:06] <caelius> No pings got through
[22:06] <genr8_> maybe you set up a MAC Address filter on your router
[22:06] <genr8_> to only allow certain clients to DHCP
[22:06] <shbrngdo> caelius - can you try the 'interfaces' method? just curious.
[22:07] <TheNik> shbrngdo: Is there no way to manually override this in the USB host? Or would this be more messy than to simply replace the WiFi chip or use an USB WiFi dongle?
[22:07] <caelius> I tried that first, days ago. You have to fully disable dhcpcd or you get multiple IPs.
[22:07] <caelius> So I did that, still got multiple IPs.
[22:07] <shbrngdo> genr8_ - yeah some "bright bulb" (read: moron) at some point made it possible to have (by default) random mac address assignments. I don't know if this was ever resolved or not. I haven't booted a newer linux image (only older ones, before that "change")
[22:07] <jonaslund> TheNik: you can always try to force the chip to be detected but considering the ID is b0rked there's a good chance there is other problems also
[22:07] <shbrngdo> it should be possible to determine whether or not the mac address is changing on every boot, though
[22:08] <caelius> I bounce it with "ip link set down/up" and boom, pings.
[22:08] <jonaslund> TheNik: my vote would go on a dongle or a new Pi3
[22:08] <caelius> What in the serious....?
[22:08] <shbrngdo> jonaslund - good point. I'm not sure where you'd do that, though. having 0 come back for MFG and device is kinda "not the standard"

[22:08] <TheNik> Nah, I'm not replacing the whole Pi just because the WiFi is broken
[22:09] <shbrngdo> TheNik - I wouldn't either. it's good for ethernet, right?
[22:09] * orti (~orti@p54A62149.dip0.t-ipconnect.de) Quit (Ping timeout: 276 seconds)
[22:09] <TheNik> I have not tried it because I have no ethernet cables laying around
[22:09] <shbrngdo> I've only been using ethernet since I only have RPI '1' and '2' at the moment
[22:09] * shbrngdo hands TheNik an ethernet cable [I've got a drawer full of old ones]
[22:10] <TheNik> But a USB dongle might be a solution. I am pretty sure I can do that. I'd closely examine if I can solder a new WiFi chip on it, though.
[22:10] <caelius> I wish I could use wifi, but I need low latency and it's too far away. This Pi is in a remote location, powered by a POE setup.
[22:10] <caelius> I can't have it "not come up sometimes".
[22:10] <shbrngdo> TheNik - if you are really good at DE-soldering, and there's nothing that requires equipment you don't have, I say 'go for it'
[22:10] * mnemonic (~semeion@unaffiliated/semeion) Quit (Ping timeout: 260 seconds)
[22:11] <shbrngdo> but yeah de-soldering will damage a circuit board REALLY FAST if you do it even slightly wrong
[22:11] <TheNik> I personally am not too good at soldering, but my father does this professionally. There is according equipment in the basement too.
[22:11] <jonaslund> depends
[22:11] <shbrngdo> TheNik - you might have HIM do it...
[22:11] <shbrngdo> don't lift a pad, or damage a trace
[22:11] <jonaslund> well... i afaik desoldering isn't that bad if you know your stuff

[22:12] <TheNik> Okay, I thank you very much for your time, guys. I'll see how I work around this.

[22:13] <caelius> Notice two things. First "Too few arguments" twice? Also, the carrier lost messages.
[22:13] <TheNik> On looking closely at the board, I have doubts if this can be soldered manually. There is a microscopic part (a capacitor, I think?) very close to the WiFi chip
[22:13] <genr8_> It looks like the IPV6 config is invalid
[22:13] <genr8_> and that stopping ipV4
[22:14] <caelius> Can I easily disable IPv6?
[22:14] <shbrngdo> caelius - the first time through it totally IGNORED your static config
[22:14] <genr8_> also... you're setting a static IP and also trying to DHCP on ipv4 it says
[22:14] <caelius> I mean, I hate that idea, but no one implements that shit right anyway and I'm not using it
[22:14] <shbrngdo> caelius - since systemd is apparently involved, I'll just blame that.
[22:14] <genr8_> yes you can
[22:14] <shbrngdo> heh
[22:14] <caelius> is the static IP I defined in /etc/dhcpcd.conf
[22:15] <genr8_> why are you using DHCP to set up static IP's ?
[22:15] <shbrngdo> caelius - the first time it said "probing address" - the 2nd time "using static address" - there's the 'reveal' of the problem right there
[22:15] <genr8_> your shits highly confused
[22:16] <shbrngdo> genr8_ - some web site told him to?
[22:16] <caelius> This is how Stretch does it now?
[22:16] <genr8_> apparently not.
[22:16] <caelius> https://raspberrypi.stackexchange.com/questions/37920/how-do-i-set-up-networking-wifi-static-ip-address/37921#37921
[22:16] <shbrngdo> I say GIVE UP on doing this with dhcpcd.conf and use /etc/network/interfaces like always before "some bright bulb" decided to change everything
[22:16] <caelius> "If you are running a recent Raspbian /etc/network/interfaces should be as below. If you have changed it PUT IT BACK. (Or on Stretch just delete it - it effectively does NOTHING.)"
[22:17] <shbrngdo> caelius - such advice is worth what you paid for it - NOTHING
[22:17] <genr8_> SEE Seperate answer: https://raspberrypi.stackexchange.com/questions/37920/how-do-i-set-up-networking-wifi-static-ip-address/74428#74428
[22:17] <genr8_> follow that one.
[22:19] <AppAraat> anyone has any experience with PiMusicBox? Is it possible to have the Pi as an AP and connect to it that way?
[22:19] <AppAraat> (Pi ZW)
[22:20] <shbrngdo> genr8_ - looks good to me. "either/or"
[22:20] <caelius> So basically say "screw dhcpcd completely"
[22:20] <caelius> Gods, documentation on the Internet is getting worse. There's too much conflicting shit.
[22:20] <shbrngdo> interestingly to use 'interfaces' with statics it said to shut off dhcpd with (cough, spit) systemd
[22:20] <caelius> And is it using systemd? Or what?
[22:20] <caelius> Or both?
[22:20] <shbrngdo> caelius - yep, if it doesn't do what you want, shut that @#$% off
[22:21] <genr8_> 59 flavors of linux don't help make it easy
[22:21] * caelius screams in administrator
[22:21] <genr8_> basics, you do realize DHCP is the exact opposite of static IP right
[22:21] <shbrngdo> "screams in administrator" - heh - how about a 'google translate' into 'administrator'
[22:21] <genr8_> keep that in mind whatever instructions you do read... don't take them verbatim, use your brain to adapt
[22:21] <shbrngdo> I think he does, he said he'd been using /etc/network/interfaces for years
[22:22] <shbrngdo> My origihal suggestion was to use it again
[22:22] <shbrngdo> genr8_ - I find B.S. suggestions online in those forums *ALL* of the time
[22:22] <genr8_> indeed. that one was just so long that it was convincing
[22:23] <shbrngdo> if you're gonna post it, you should try it yourself and paste the log
[22:23] <caelius> Yeah
[22:23] <caelius> I actually tried the interfaces stuff first, but had issues with multiple IPs.
[22:23] <caelius> Found that article and others and thought, "oh, well, it's done a different way now, so I'll do that"
[22:23] <caelius> Trying interfaces again right now
[22:23] * goiko (~goiko@unaffiliated/goiko) Quit (Quit: ﴾͡๏̯͡๏﴿ O'RLY? Bye!)
[22:24] <genr8_> I found this on the official wiki https://wiki.archlinux.org/index.php/dhcpcd#Fallback_profile
[22:24] <shbrngdo> multiple IPs ? you can set up aliases in 'interfaces' to make that happen, if you want it. also set up IPv6 statically
[22:24] <genr8_> multiple IPs is aliases and different
[22:24] <caelius> Right, but interfaces was giving one and so was dhcpcd, I think.
[22:24] <caelius> So I was getting both the static and a dynamic.
[22:24] <caelius> OK. It came up with the static. Trying a few more restarts
[22:25] <shbrngdo> I've always had to have an alias device to get a 2nd IP address. is it possible to have more than one on a single interface in Linux? [IPv6 obviously does this but it's IPv6]
[22:25] <genr8_> it probably just changed your current one
[22:25] <shbrngdo> ack - that's what I remember
[22:25] <genr8_> i doubt its possible to have multiple IPs on a single IF with no alias
[22:26] <shbrngdo> freeBSD is similar that way
[22:26] <shbrngdo> the alias names are different but it's the same concept.
[22:26] <caelius> No, it was two: a dynamic and a static.
[22:26] <caelius> It was crazy
[22:26] <shbrngdo> caelius - yeah that's a problem in and of itself

[22:28] <shbrngdo> caelius trade for a semi-broken one first, then smash THAT one
[22:28] <caelius> This Pi is in a weatherproof enclosure 100 feet from my office, outside.

[22:29] <caelius> OK. OK. HAHAHAHA
[22:29] <caelius> Get this.
[22:29] <caelius> It came up. Pings from my desktop box were failing.
[22:29] <caelius> You know what "ip addr" shows?
[22:29] <shbrngdo> not a clue
[22:29] <caelius> eth0 is down, but has an IP, and NO-CARRIER
[22:29] <shbrngdo> bad cable?
[22:30] <genr8_> could be the POE ?
[22:30] <caelius> Nope. Tested good
[22:30] * Nephilum (~Raspberry@ Quit (Quit: Leaving)

[22:31] <shbrngdo> try moving the ethernet cable to a different port on the switch, see if it's that
[22:31] <genr8_> thinking
[22:32] <caelius> I just....If I had hair (I have a shaved head), I'd pull it all out.
[22:32] <caelius> shb: Yep. Tried that, too.
[22:32] <caelius> I tried all the simple hardware stuff first.
[22:32] <shbrngdo> also is the cable very long? gigabit ethernet hates long cables
[22:32] <caelius> This cable? No. 20 feet, I think.
[22:32] <caelius> Maybe 15
[22:32] <caelius> Just across the room
[22:33] <shbrngdo> might be marginal. I suggest throttling it down to 100mbit. I dno't know the command to do it, however. ifconfig usually has something, a mode, or whatever

[22:33] <AppAraat> what have I heard, not all class compliant USB devices may work on Raspbian?
[22:33] <genr8_> good idea
[22:33] <shbrngdo> AppAraat - I've heard it's the hardware that causes that little problem
[22:33] <shbrngdo> bcm's USB implementation
[22:33] <shbrngdo> "non-cheapies" probably ok
[22:34] * minionofgozer (~minionofg@ has joined #raspberrypi
[22:34] <AppAraat> hardware of the RPi? Assuming the device works on an Ubuntu laptop, could it also work on the RPi?
[22:35] <shbrngdo> AppAraat - again, broadcom's implementation with USB is known to be 'iffy' with certain devices. Give it a try, see what happens
[22:35] <TheNik> No, replacing the WiFi chip does not seem possible. I'll go with a USB adapter, then
[22:35] <shbrngdo> Raspbian should have the same class-based drivers as ubuntu [since they're derived from Debian] and so I would expect it to work
[22:36] <shbrngdo> TheNik - you should trade RPis with caelius so he can smash YOURS with a hammer, instead
[22:36] <shbrngdo> heh
[22:36] <caelius> One difference between the non-working and working times? IPv6
[22:36] <shbrngdo> I'm not sure how to set up static IPv6 with interfaces - never tried it
[22:36] <shbrngdo> but I think it's interfering
[22:37] <caelius> Hrm. So it sometimes doesn't get a "scope global" IPv6 address
[22:37] * JessicaRN (6cd0b44b@gateway/web/freenode/ip. Quit (Ping timeout: 260 seconds)
[22:37] <caelius> And when it doesn't, the interface is in some wacky state where even IPv4 isn't working.
[22:37] <TheNik> shbrngdo, caelius: Deal
[22:37] <shbrngdo> caelius - there are 3 methods for getting IPv6 - one is a local link address [you always get], one is dhcpv6, and the other involves the routing protocol as I recall
[22:38] <shbrngdo> caelius - I don't know what happened to dhcpd to cause this on Raspbian, but as it's apparently tied in with systemd now, could be anything. could be nothing.
[22:38] <AppAraat> shbrngdo: so I've read that my DAC should work with Pi3, does the Pi ZW have the same USB chips?
[22:38] <caelius> Deal with what?
[22:38] <shbrngdo> AppAraat - most likely it's the same, as it's on the silicon of the SoC
[22:38] <caelius> Not getting a network connection because IPv6 is hanging the interface? Unacceptable
[22:39] <TheNik> caelius: We trade Raspberry Pi(e)(')(?)s for you to smash a broken one with a hammer, instead of a working one :P
[22:39] <shbrngdo> caelius - you should be able to disable ipv6 easily. not sure what command though, maybe some (profanity) systemd setting

[22:42] <shbrngdo> you'd probably have to have an entry for it in some config file. I'm not familiar with how that works in Linux, and I suspect that a match to 0,0 will fail anyway
[22:43] * jrofd (~test@gateway/tor-sasl/jrofd) has joined #raspberrypi

[22:46] <caelius> No IPv6 listed. Trying some reboots again
[22:46] <shbrngdo> caelius - I found this that describes a static entry for ipv6 in 'interfaces' - https://askubuntu.com/questions/566255/how-to-configure-etc-network-interface-to-use-static-ipv6-but-dynamic-ipv4
[22:47] <shbrngdo> basically it's like ipv4 but you use 'inet6'
[22:47] <shbrngdo> anyway, if you go "pure static" it will probably help, then shut off the interfering dhcpd with systemd's command thingy
[22:48] <caelius> That wasn't it
[22:48] <caelius> Son of a
[22:48] <shbrngdo> oh?
[22:48] <caelius> It came up on boot. My rc.local bounces the interface still...and that caused it to come back with NO-CARRIER
[22:48] <TheNik> Meanwhile, I provide my Raspberry Pi with internet access through my phone, which is kind of hack-y, but as long as it works ¯\_(ツ)_/¯
[22:48] <shbrngdo> why is rc.local bouncing your interface? can you enable things one at a time until you find it?
[22:49] <shbrngdo> also have you tried using a shorter cable? [plug ether switch between them with short cables?]

[22:50] <shbrngdo> or 100mbit?

[23:17] <shbrngdo> all should be explained there, but not necessarily 'all in one spot'

[23:18] <JessicaRN> I've attached my pir and led as shown, but I'm wondering if my gpios are in different positions
[23:19] <JessicaRN> and if python is refering to physical pins or gpio numbers
[23:19] * Alexander-47u (~Alexander@ Quit (Remote host closed the connection)
[23:19] <shbrngdo> oh ok it's using RPIGPIO python lib
[23:19] <JessicaRN> yes
[23:19] <shbrngdo> that code doesn't indent properly
[23:19] <JessicaRN> but i'm using the rpi3b+
[23:20] <JessicaRN> yeah, I've indented properly
[23:20] <shbrngdo> just making sure. yeah the 3b+ should still work as far as I know, since it's supposed to have a header identical to RPI 2
[23:20] <JessicaRN> my code seems to run ok but it's always triggering motion
[23:21] <shbrngdo> if it outputs a 5v (high) signal it needs level conversion or at least a series resistor on the input pin
[23:21] <shbrngdo> you shouldn't be applying >3.3v to any pin on the RPI
[23:21] <JessicaRN> so if I use "GPIO.setup(3,GPIO.OUT)" does this refer to the physical pin number or the GPIO number?
[23:22] <shbrngdo> gpio number (not the pin number) as far as I'm aware
[23:22] <shbrngdo> you cuold verify it by hacking up a quicky python application that slowly toggles an I/O pin, then put an LED or a meter on it
[23:24] <JessicaRN> shbrngdo: so, the two pins farthest from the USB are: 3.3vdc and 5vdc. the next row is gpio 8 and 5vdc. is that correct?
[23:25] <alex_giusi_tiri2> hi! i think i have psu issues. [pi 3b] what is the min recommended amp for safe usage, if I would use (no abuse/overvlocking) the board to its max -- if I would attach all peripherals at once (usbs (assume each port uses max std), eth, wifi, bt, gpio), max cpu usage at max std freq, etc. what amount of amps would then be safely sufficient? (think of the lowest common denominator/greatest common factor type of thing)
[23:25] <shbrngdo> actually that doesn't quite sound right. see this diagram: https://elinux.org/images/8/80/Pi-GPIO-header-26-sm.png (that's for the 23-pin header)
[23:26] <shbrngdo> for the 40-pin header it's this one: https://elinux.org/images/thumb/5/5c/Pi-GPIO-header.png/300px-Pi-GPIO-header.png

[23:30] <shbrngdo> it says "this is not the raw broadcom GPIO numbers" - that's why. i was really concerned there for a bit...
[23:31] * shbrngdo only deals in the raw broadcom GPIO numbers
[23:31] <JessicaRN> wtf? are there different gpio numbers on the same board?
[23:32] <shbrngdo> it has to do with something that wa done with 'wiringPi' - I wouldn't worry too much. I'm pretty sure that the default is to use the raw GPIO numbers

[23:32] <shbrngdo> so your python program should work if you use the ones on the diagrams I gave you. that might be all it is, actually
[23:32] <JessicaRN> which one corresponds to RPi.GPIO in python3?
[23:33] <alex_giusi_tiri2> i looked at the official faq, and 2.5A are recommended, but I have 2.4, and i am still worried even id i have only a kb attached, because of what it does
[23:33] <shbrngdo> JessicaRN - probably (by default) the raw ones. try using the diagram I gave you, pick an IO pin as an output, and slow-toggle it in a test application to verify
[23:34] <shbrngdo> I'm pretty sure wiringPi uses the broadcom numbering by default. you can use flags to tell it to use "the other ones"
[23:34] <shbrngdo> but I'm only working on a port for it at the moment, and haven't actually coded with it in python...

[23:35] <shbrngdo> by the way that p4j reference is "yet another example" of misleading stuff on "teh intarwebs". I think I'll take a cat-5-o-nine-tails to the next one
[23:35] <JessicaRN> okokok... so when I toggle "GPIO.output(3,0)" i get a led to light on and off that is tied to physical pin3 / GPIO8 as shown on this diagram: http://pi4j.com/pins/model-3b-plus-rev1.html
[23:35] <shbrngdo> now you know what the default numbering is. ok, good enough. carry on
[23:36] <shbrngdo> also - keep in mind that applying a 5V output from that detector is *VERY* *BAD* for the RPi's GPIO pin. at the very least, use a 200 ohm series resistor on it
[23:36] <shbrngdo> better still, a 220 ohm + 330 ohm resistance ladder, such that it's 5V -> 220 ohm -> GPIO pin -> 330 ohm -> ground
[23:37] <shbrngdo> where '5V' is the logic output that goes to 5V
[23:37] * sigsts (~sigsts@unaffiliated/skyroverr) Quit (Remote host closed the connection)
[23:37] <shbrngdo> that would be a simple level converter. if you find yourself doing level conversion a LOT you can get breakout boards that do this from sparkfun
[23:37] <JessicaRN> shbrngdo: that output pulls the pin down. according to the datasheet you need a pullup resistor. I'm using the internal pull up (or at least I think I am.)
[23:38] <shbrngdo> that might be the entire problem right there. OK how about a 2.2k resistor to 3.3v on that IO pin ?
[23:38] <shbrngdo> don't pull it up to 5V, pull to 3.3v
[23:38] <JessicaRN> GPIO.setup(11,GPIO.IN,pull_up_down=GPIO.PUD_UP)
[23:38] <JessicaRN> thats what I'm doing
[23:39] <shbrngdo> I would think that would work. however if it's always a zero, maye the resistor is too large? internal pullups are 50k I think
[23:39] <JessicaRN> so tie a physical 10k to the 3.3vdc?
[23:39] <shbrngdo> if you disconnect the detector at pin 11, what is the voltage on the GPIO pin? if it's ~3.3v its worknig
[23:39] <shbrngdo> JessicaRN - physical 10k is probaby good too.
[23:40] <JessicaRN> k. i'll give that a try. ty for the help
[23:40] <shbrngdo> I usually use ~2k for pullups, since it works for TTL or CMOS, more or less

[23:44] <alex_giusi_tiri2> if the power led occasionally blinks/turns off for various time lengths, would that be normal?
[23:44] <shbrngdo> good question - anything can toggle it

[23:53] <alex_giusi_tiri2> i am using gentoo arm64 with openrc, no gui. sometimes, but mostly during high cpu usage, the screen sets back to showing the initial bootup log (starting up services), and a power icon is briefly displayed on the top-right corner. it also becomes somewhat unresponsive momentarily. i am concerned that the psu is not enough. i have an anker (powwer port 10) A2133, which I thought would be enough. what do you think?

[23:58] <javi404> or better USB cable
[23:59] <javi404> or ideally both.
[23:59] <alex_giusi_tiri> the cable is new
[23:59] <alex_giusi_tiri> how much power?
[23:59] <javi404> alex_giusi_tiri2: taking a look at the anker
