[3:15] <michelp> hello, i have an rpi 3 B, it works great in this little touch display I have. Today I received my new 3 B+ and I figured it would be an exact swap, sd card, display, everything, but when i turn it on, it's stuck on the "rainbow" color field and never boots
[3:15] <michelp> was my assumption wrong? or maybe I got a bad 3B+?
[3:16] <michelp> when i swap back in the 3B, it all works great

[3:36] <leftyfb> s1car1us: can we help you with something?
[3:36] <s1car1us> maybe... what are you offering?
[3:38] <leftyfb> s1car1us: why did you post a link to what looks like a nefarious android file?
[3:39] <s1car1us> thats kinda presumptuous
[3:40] <leftyfb> s1car1us: it most certainly is. You haven't posted anything in here since October and out of the blue you randomly post a link to "DefSec.apk". Got another explanation?
[3:40] <michelp> leftyfb: that worked great thank you!!
[3:40] <michelp> booted right up
[3:40] <s1car1us> why do I need one?
[3:41] <leftyfb> s1car1us: what is that file for exactly?
[3:41] <s1car1us> I dont know... I was trying to forward it to a private chat...
[3:41] <s1car1us> cant hurt you if you dont donwload it and install it though
[3:42] <s1car1us> you can try though and let me know what happens
[3:43] * Zardoz (~Zardoz@cpe-70-124-157-79.austin.res.rr.com) has joined #raspberrypi
[3:44] <s1car1us> im not phishing tho if thats what you are implying... Im more of a spear kind of guy...
[3:44] <ali1234> it deploys a payload with metasploit and then pings a CnC server on time warner cable
[3:45] <ali1234> do not download this

[3:48] <dogbert_2> LOL...world's best low-tech car chase scene in a Bond movie: https://www.youtube.com/watch?v=4zBbLFevW1s
[3:49] <leftyfb> s1car1us: if you're going to "accidentally" post a link to such a file in a public channel such as this, the least you could have done was immediately tell people not to download and run it. Some people don't know better and they do not not deserve whatever it is you plan on doing with their device on you have exploited it.
[3:50] <s1car1us> I am not trying to hack anyone from the raspberrypi channel... calm down
[3:50] <leftyfb> please read what I just typed
[3:50] * Zardoz (~Zardoz@cpe-70-124-157-79.austin.res.rr.com) has joined #raspberrypi
[3:50] <leftyfb> a quick warning and even an apology would have been nice
[3:50] <Xark> leftyfb: FYI, he also "accidentally" posted it in #arduino...
[3:51] <s1car1us> I posted it everywhere...

[3:52] <leftyfb> again, warnings and apologies would make it less of a bad move
[3:53] <s1car1us> look at the channels I am a member of... you think I am going to be trying to pass off a trojan in that type of rookie way... My apologies... I was using my phone and wasnt getting the result I intended
[3:53] <s1car1us> Like I said, even if someone had downloaded it and installed it, there is nothing that would of come of it.
[3:54] <leftyfb> except the fact that it's got a payload that pings a CnC server .... yup, sounds harmless

[4:11] <shugshug> I had build-essential, will try devscripts.
[4:12] <ali1234> you need the linux-headers package (but it might have a different name... not sure)
[4:13] * sucks_ (~sucks@2804:7f1:2080:4573:5e72:e45:bf70:7584) has joined #raspberrypi
[4:13] <ali1234> it sounds like you are trying to build an "out of tree" kernel module
[4:13] <ali1234> for that you need kernel headers that match your running kernel
[4:14] <ali1234> so you need to get the exact one
[4:14] <ali1234> or... not the running kernel, bt whatever kernel you want to build the module for
[4:15] * wgas (~wgas@unaffiliated/wgas) has left #raspberrypi
[4:16] <shugshug> yes. I pulled raspberrypi-kernel-headers
[4:16] <shugshug> and then did a symlink from where they were installed to the build folder
[4:17] <s1car1us> you need to cross compile
[4:17] <shugshug> when I apt-get for exact version, is not there
[4:17] <shugshug> *pull
[4:17] <ali1234> did you run rpi-update?
[4:17] <shugshug> yes
[4:17] <ali1234> that's the problem then
[4:17] <shugshug> please elaborate
[4:18] <ali1234> rpi-update gives you a pre-release kernel.. there are no headers for it in raspbian repositories, so raspberrypi-kernel-headers will not work
[4:18] <ali1234> you will not be able to get the right versions that way
[4:18] <shugshug> and the fix, then?
[4:18] <ali1234> don't run rpi-update, or build the whole kernel yourself
[4:18] <s1car1us> you are trying to compile a driver kernel on the rpi itself?
[4:18] <shugshug> I'm pretty sure this is not the issue, though, cus I pulled the kernel headers BEFORE running rpi-update
[4:19] <ali1234> which also means not using rpi-update
[4:19] <shugshug> can rpi-update be rolled back?
[4:19] <ali1234> it can be, yes, you just reinstall the raspbian kernel packages
[4:19] <s1car1us> * a kernel with new driver....
[4:19] <shugshug> I have the "noobian" image
[4:20] <ali1234> no idea what that is
[4:20] * Lerch (~lerch@cust-76-72-150-36.static.razzolink.com) has joined #raspberrypi
[4:20] <shugshug> what packages would I reinstall
[4:20] <ali1234> i don't know, i've never had to do this
[4:20] <s1car1us> Just build it on debian
[4:20] <shugshug> (it is a raspbian image already ready to go, downloaded from rpi.org
[4:20] <ali1234> out of tree is always a pain
[4:21] <s1car1us> look up cross compiling... its not that bad...
[4:21] <shugshug> ali1234: please elaborate
[4:21] <shugshug> err. sicariua
[4:21] <shugshug> I meant
[4:21] <ali1234> cross compiling actually is fairly easy if you have a linux build system
[4:21] <ali1234> however it won't make your out-of-tree problems go away
[4:21] <s1car1us> Thats what I just said... hehe
[4:22] <s1car1us> you have the source for noobian?
[4:22] <shugshug> no
[4:22] <shugshug> was an image
[4:22] <ali1234> there is a guide on how to do it from the official source: https://www.raspberrypi.org/documentation/linux/kernel/building.md
[4:22] <s1car1us> oh i c
[4:22] <s1car1us> find the source... should be available
[4:23] <ali1234> what you say noobian you mean NOOBS right?
[4:23] <s1car1us> IDK what image he is using, I just said he called it noobian
[4:23] <s1car1us> *saw
[4:23] <shugshug> yes NOOBS
[4:24] <s1car1us> So find the source for that image.... then pull out the kernel, run the config and build it...
[4:24] <ali1234> the source is here https://github.com/raspberrypi/linux
[4:24] <ali1234> this is covered in the official guide
[4:25] <s1car1us> and ya, check the link ali1234 is posting
[4:25] <s1car1us> what driver are you trying to add to it?
[4:26] <ali1234> NOOBS is just a bootloader really
[4:27] <ali1234> you are running raspbian as the distribution
[4:27] <ali1234> unless you installed something else on top of it
[4:33] <shugshug> ok. That link was not what I needed.
[4:33] <shugshug> sicarius: I am writing my own driver for a breadboard connected to a couple of GPIO
[4:33] <ali1234> no, not really. cos even after you have built your own kernel, it still wont have the driver you want
[4:34] <shugshug> the functionality of hte breadboard all good
[4:35] <shugshug> the problem is I am trying to now compile it as a module, and it is failing on includes of basic header files
[4:35] <ali1234> well "basic" headers aren't available inside the kernel
[4:35] <shugshug> yes! which is why I tried to download kernel-headers
[4:36] <shugshug> and came to the problem I mentioned when I first entered the chat room
[4:36] <ali1234> this is a different problem
[4:36] <ali1234> the kernel does not have stdlib functions available
[4:36] <shugshug> what?
[4:37] <ali1234> stdio.h is not available in kernel code for example
[4:37] <shugshug> yes. that is one of the headers that is not being found by compiler
[4:37] <shugshug> that and sys/stat.h
[4:38] <ali1234> for example if you use printf in your code
[4:38] <ali1234> in a kernel module you have to use printk instead
[4:38] <shugshug> you mean the functionality offered by stdio i not available?
[4:38] <ali1234> right
[4:38] <shugshug> yes. I am using printk
[4:40] <shugshug> what about sys/*.h?
[4:40] <ali1234> then don't include stdio.h
[4:40] <shugshug> and fcntl.h?
[4:40] <ali1234> i don't know, i haven;t done kernel dev for years :)
[4:41] <ali1234> i can't remember it
[4:41] <ali1234> why do you need those includes?
[4:41] <ali1234> what functions?

[5:28] <NowhereMan> do you mean paypal credit card?
[5:29] <ShapeShifter499> I mean credit card
[5:29] <NowhereMan> cant you pay with paypal using the card as a funds source?

[5:30] <NowhereMan> but you can use any credit card to pay thru paypal

[9:03] <Zardoz> what do you mean?
[9:03] <Hercules`> The WiFi
[9:03] <Zardoz> ????
[9:03] <Hercules`> I live my school campus, we just have wifi not the ethernets..
[9:04] <Hercules`> I already bought TP-Link TL-WN823N

[9:04] <Zardoz> ok, so retuen it and get one that does not need a driver donloaded and installed.
[9:05] <Hercules> I already opened box, they wouldn't return it
[9:05] <Hercules> unless there is a flaw in manufacturing
[9:06] <Hercules> Even if there is a flaw, they'll just replace it.
[9:06] <Zardoz> sounds bad. who is this pplace so i dont buy from them.
[9:07] <Hercules> its amazon :x
[9:07] <Zardoz> RETURN IT
[9:07] <Hercules> so you want me to buy those cheap, non-branded wifi?
[9:08] <Hercules> I wouldn't be able to find support on them either
[9:08] <Hercules> if they asked for drivers aswell
[9:08] <Zardoz> no, I would want you to by one that works what the device you are buying it for.
[9:08] <Hercules> which is the device that works? :X
[9:08] <Hercules> with this device
[9:08] <Zardoz> compatibility wised
[9:09] <Hercules> it must be having name?
[9:09] <Hercules> I bought this one looking in reviews aswell
[9:09] <Hercules> people work like "Hey!! Works perfect with my RPi2"
[9:09] <Hercules> work like -> were like*
[9:09] <Zardoz> sure after they downloaded drivers
[9:10] <Hercules> pfff
[9:10] <Hercules> Looks like I'll have to help myself..
[9:10] <Zardoz> sorry, but good luck. I am sure there might be some work around but most like will not be EZ

[11:36] <mlelstv> no idea if OpenWRT does this.
[11:36] <ShapeShifter499> would it be possible to enable DHCP in this method?
[11:37] <mlelstv> you could check what happens. Do a tcpdump on the host uplink and look for icmp, and then ping on the pizero an outside address
[11:38] <mlelstv> you should be able to use DHCP, but if you cannot fix the IP addresses, you need a hook to regenerate the PPP configuration

[13:01] <ShapeShifter499> pksato: ^^
[13:02] <pksato> ok, lets me think...
[13:04] <ShapeShifter499> the all the usb connected ethernet gadget Pis get internet
[13:04] <ShapeShifter499> I can update and install packages fine. I can also ping just fine
[13:06] <pksato> on ppp server, just for cheking, sysctl net.ipv4.ip_forward
[13:06] <pksato> return 1 ?
[13:09] <ShapeShifter499> pksato: yes
[13:10] <pksato> next, the ppp ip pair, is local:remote
[13:12] <pksato> on server side, local is ip of the ethernet connected to main router.
[13:14] <mlelstv> where does the 06:3d:63:e8:46:97 come from?
[13:14] <mlelstv> is there a /etc/modprobe.d/g_ether.conf ?
[13:15] <pksato> I not remember if local ip is other that ethernet ip, proxyarp works.
[13:15] <ShapeShifter499> pksato: the guide I used told me to make the IP different from the IP that the host uses for internet
[13:15] <pksato> ShapeShifter499: yes.
[13:15] <ShapeShifter499> but one that isn't used on the LAN
[13:16] <pksato> Yes, I flowing the guide and try to remember how to use ppp.
[13:16] <ShapeShifter499> mlelstv: I don't know where that MAC comes from, I just set the MAC via the cmdline options
[13:17] <ShapeShifter499> /etc/modprobe.d/g_ether.conf does not exist
[13:17] <mlelstv> every description I read says that the cmdline options should work. So either there is a typo or something is overriding it.

[14:21] <shbrngdo> right, you're trying to make sure the bridge knows about the mac addresses in quetion
[14:22] <mlelstv> it should just broadcast arp queries and forward the results. Something there doesn't work.

[14:23] <shbrngdo> any USB network interface maker that distributes mutliple devices with the same MAC address needs to be whipped with a cat-5-o-nine-tails
[14:24] <mlelstv> now the guest rpi should be able to ping the linux host and vice versa.
[14:24] <shbrngdo> might wanna run 'traceroute' to verify
[14:25] <mlelstv> no routing used :)
[14:25] <shbrngdo> from the 'guest pi' to a computer on the network? that's what I'm thinking
[14:25] * Trieste (~T@unaffiliated/trieste) Quit (Ping timeout: 268 seconds)
[14:25] <shbrngdo> should see at least 2 hops
[14:26] <mlelstv> it's guest pi <-ppp-> host pi <-g_ether-> linux host
[14:26] <mlelstv> and it's all the same network and the host pi does proxy arp for the guest pi.
[14:26] <shbrngdo> right - so you should see that in traceroute
[14:26] <mlelstv> no routing, just layer 2
[14:26] <shbrngdo> you're tunneling to the linux host?
[14:26] <mlelstv> no tunnel :)

[14:27] <shbrngdo> something doesn't add up here.
[14:27] <mlelstv> yes, but what :)
[14:27] <mlelstv> hmm
[14:28] <mlelstv> how did you setup the bridge and ethernet on the host?
[14:28] <shbrngdo> if your host pi is a ppp server, you still have to route packets to the linux host
[14:28] * Trieste (~T@unaffiliated/trieste) has joined #raspberrypi
[14:29] <mlelstv> not sure if you can see that
[14:29] <shbrngdo> I've been doing networking for 20+ years. FYI.

[14:30] <shbrngdo> right and the point is that if there's no route from 'guest pi' to 'linux host' that involves 'host pi' as a gateway, it's not gonna work
[14:30] <mlelstv> the guest rpi has a default route to the host rpi
[14:30] <shbrngdo> unless the ppp interface is bridged with the ethernet, in which case it may be misconfigured
[14:31] <mlelstv> the host rpi has an interface route to the linux host
[14:31] <mlelstv> ppp cannot be bridged
[14:31] <mlelstv> ppp is L3
[14:31] <shbrngdo> it creates a 'tun' adaptor though, right?
[14:32] <shbrngdo> or maybe it's not set up to do that [and thus begins the problem]
[14:32] <mlelstv> should be a ppp interface, not tun.

[14:38] <shbrngdo> here's a question: what IP subnet is the ppp using, and what IP subnet is the network using?
[14:38] * nighty- (~nighty@s229123.ppp.asahi-net.or.jp) has joined #raspberrypi
[14:38] <shbrngdo> because I'm already seeing a routing issue here. your primary gateway probably doesn't know what gateway to send packets to for the guest pi

[14:39] <mlelstv> it's all the same ip net 192.168.1.0/24
[14:39] <shbrngdo> so one of the first things you might want to do is run wireshark, on 'linux host'
[14:39] <shbrngdo> then send the ping packets. then observe "did it or not" on 'linux host'
[14:39] <mlelstv> there is a point-to-point link from 192.168.1.100->192.168.1.101 which is a more specific route
[14:40] * MacGeek (~BSD@host188-77-dynamic.180-80-r.retail.telecomitalia.it) has joined #raspberrypi

[14:40] <shbrngdo> ok tcpdump is fine. you can see packets there, and that's my point
[14:40] <shbrngdo> so does the ppp link work at all?
[14:40] <mlelstv> we can see packets going from guest pi to linux host. But no answer.
[14:41] <mlelstv> ppp works fine
[14:41] * s8548a (~s8548a@unaffiliated/s8548a) has joined #raspberrypi
[14:41] <shbrngdo> that's because linux host doesn't know how to route them back. been there, done that. try a manual routing entry on 'linux host' see if that fixes it. use 'pi host' as the gateway
[14:41] <mlelstv> we see the arp query on the bridge

[14:41] <shbrngdo> humor me.
[14:42] <mlelstv> that's the linux host asking for the mac address
[14:42] <mlelstv> but no answer to that
[14:42] <shbrngdo> and guess what? it can't get an answer from pi host right?
[14:42] <mlelstv> it is probably sent to the ethernet
[14:42] <mlelstv> not to the usb interface
[14:42] <shbrngdo> probably is, yes. routers would handle that by the way
[14:42] <ShapeShifter499> from the Host pi to the linux box, pings work fine https://gist.github.com/ShapeShifter499/73e076b1fab24e829e2d577a1e5c7f52
[14:42] <mlelstv> the host pi does proxyarp. It answers arp requests for the other side of the ppp link.

[14:43] <shbrngdo> you sure that works? can you do 'arp -a' on linux host and see the mac address for the guest pi ?
[14:44] <shbrngdo> keep in mind that if there's no bridge between adaptors on a multi-homed system, the primary adaptor will get the request but others probably won't
[14:44] <shbrngdo> so maybe 'linux host' also needs to bridge its usb adaptor with the ethernet
[14:44] <shbrngdo> normally when I do something crazy like this I put 2nd adaptor on its own subnet and configure routing
[14:45] <mlelstv> hmm
[14:45] * shbrngdo says - surprise, it's a routing problem!

[14:46] * Keanu73 (~Keanu73@2ProIntl/User/Geek/Keanu73) has joined #raspberrypi

[14:46] <shbrngdo> yes, RIP
[14:46] <shbrngdo> or you can manually configure them [test networks for example]
[14:47] <mlelstv> but probably not the router to the cable modem.
[14:47] <shbrngdo> you could set up an alternate subnet on an existing ethernet using manual routing entries on both ends
[14:47] <mlelstv> that's why people use things like proxyarp.
[14:47] <shbrngdo> as long as "something along the way" knows to forward packets to and from the cable modem's gateway, all should be fine

[14:50] <mlelstv> hmm.
[14:50] <mlelstv> maybe it's reverse path filtering.
[14:51] <mlelstv> shapeshifter, please try sysctl -w net.ipv4.conf.all.rp_filter=0 first on the linux host, then on the rpi host
[14:51] * djk (~Thunderbi@pool-96-242-161-125.nwrknj.fios.verizon.net) has joined #raspberrypi
[14:51] <shbrngdo> here's what I think is happening: guest pi knows how to route packets to linux host, but linux host is confused about how to route packets back to guest pi. the cause appears to be the use of a USB ethernet AND a regular ethernet on linux host. linux host uses the primary adaptor because they're on the same subnet
[14:52] <shbrngdo> now, if linux host were a router, AND the host pi and guest pi were on a separate subnet, linux host woudl become the primary gateway for the 2nd subnet, and all would be fine. or you can bridge its two adaptors
[14:52] <mlelstv> the linux host uses the bridge which should broadcast arp queries to all interfaces and send answers to the port where the destination is.
[14:53] <shbrngdo> so are the two adaptors correctly bridged on linux host? that's somethign to check
[14:53] <mlelstv> the bridging on the linux host is fine.
[14:53] <shbrngdo> you can ping 'host pi' from linux host ?
[14:53] <mlelstv> sure.
[14:54] <shbrngdo> ok - then can you add a manual route for 'guest pi' that uses 'host pi' as its gateway on 'linux host', and try the ping again?
[14:55] <shbrngdo> I guess that would be directed to ShapeShifter499
[14:56] <shbrngdo> by the way this isn't "the fix" it just reveals the source of the problem
[14:57] <ShapeShifter499> shbrngdo: the host pi and the linux box can ping each other
[14:59] <ShapeShifter499> shbrngdo: how do I add that?/
[15:00] <shbrngdo> 'man route' but it should be something like [if I remember correctly] route add 192.168.1.102 gateway 192.168.1.101 <-- not sure if that is right where 192.168.1.101 would be the host pi, and 192.168.1.102 would be the guest pi. I think it's route del 192.168.1.101 to remove it after you test
[15:00] <mlelstv> please no
[15:00] <shbrngdo> or you can keep going this way, whichever
[15:01] <shbrngdo> this would be temporary only, to test that routing is the problem, by manually configuring a route to see if the packets get through
[15:02] <shbrngdo> again, I've done this to set up private LAN spaces over a common ethernet

[15:06] <shbrngdo> in any case, if you did that and you still cannot reach guest pi from linux host, then the problem most likely isn't routing. If it _DOES_ work, then the problem is routing.
[15:06] <shbrngdo> you'v then ruled out a gigantic subsystem with a single test. Thank you, 6 step troubleshooting method from U.S. Navy electronics school
[15:07] <shbrngdo> the principle is to rule in or out an entire subsystem with a single test, whenever you can. this helps narrow down the focus very rapidly.

[15:08] <shbrngdo> OR, you can do somethign that takes 1 minute and rule out AN ENTIRE SUBSYSTEM. your choice.

[15:19] <ShapeShifter499> shbrngdo: I thought ppp was supposed to do that?
[15:19] <shbrngdo> ppp is a serial protocol that behaves like an ethernet adaptor
[15:20] <shbrngdo> if you do an ifconfig on 'host pi' you should see two adaptors. You could try bridging them. but if you do that it might break the network connection so hopefully you're not runnign headless
[15:20] <mlelstv> you cannot bridge ppp
[15:21] <shbrngdo> as ppp0? you sure?
[15:21] <mlelstv> yes
[15:21] <shbrngdo> ok - then you'll have to live with routing. I suggest a different subnet for the ppp stuff
[15:21] <mlelstv> ppp is IP layer, not MAC layer.
[15:21] <mlelstv> and to avoid routing you use proxyarp :)
[15:22] <shbrngdo> saw this old resource earlier, not sure if it helps - http://linux-sxs.org/networking/pppservr.html
[15:22] <shbrngdo> according to that page, proxyarp is not needed
[15:22] <mlelstv> shapeshifter, my next suggestion would be to clear rp_filter
[15:23] <mlelstv> you either need routing or can work around using proxyarp
[15:23] <shbrngdo> one way or another yeah

[15:40] <ShapeShifter499> if it works without 'proxyarp' then why was it even required. Why did the guide even bother having that option
[15:40] <mlelstv> whatever works now works, because you have configured explicit routes everywhere.
[15:41] <mlelstv> did you try the rp_filter ?
[15:41] <pksato> proxyarp on wrong interface?
[15:41] <ShapeShifter499> that route command shbrngdo was temporary right?
[15:41] <ShapeShifter499> pksato: look at my config for ppp https://gist.github.com/ShapeShifter499/c4434a1733785f38f46dbb8c22975922
[15:41] <ShapeShifter499> was I suppose to specify a interface after the 'proxyarp' entry?
[15:42] <mlelstv> no
[15:42] <shbrngdo> SpaheShifter499 - yes - if you do 'route print' it should show only 2 or 3 entries (the normal ones) after booting
[15:42] <mlelstv> linux default is rp_filter enabled. That blocks packets that have no specific route.
[15:44] <shbrngdo> I guess that's route without the 'print' - different systems...
[15:44] <shbrngdo> I tested on linux VM, had 2 lines in it
[15:44] <ShapeShifter499> power cycle, now everything is borked again
[15:45] <ShapeShifter499> might have been the route command then
[15:45] <ShapeShifter499> I can still ssh between the Pis though

[15:47] <shbrngdo> that makes sense. so in short if 'proxyarp' was set up correctly, then the problem is that for some reason your linux host machine can't determine the guest pi's mac address. But that doesn't soudn likely. what sounds likely is that the 'proxy arp' thing isn't doing its job.
[15:48] <ShapeShifter499> oh ok, so once everything is running and fully up I can restart the ppp service on the Guest Pi which makes everything work
[15:48] <mlelstv> the proxyarp couldn't do anything because the linux host didn't send arp queries.
[15:48] <mlelstv> and we need to find out why that happens.
[15:48] <ShapeShifter499> I need to delay the ppp service it seems
[15:48] <mlelstv> my first thought was the common mac addresses
[15:48] <shbrngdo> now, let's say the USB ethernet is eth1. you could try (from linux host) 'ping -I eth1 ipaddress' where 'ipaddress' is the pi guest, see if that works
[15:48] <mlelstv> but I now believe its rp_filter :)
[15:48] <shbrngdo> and then monitor all communications on eth1 while you do it

[15:49] <ShapeShifter499> mlelstv: restarting ppp after everything else is connected gets the Guest Pi on the network
[15:49] <shbrngdo> wait - 'once everything is running you can restart the ppp service on guest pi which makes everything work' - that's a bit different
[15:50] <ShapeShifter499> shbrngdo: yes, I just did that as a test
[15:50] <shbrngdo> I was re-stating it for confirmation
[15:50] <ShapeShifter499> proxyarp is still commented out in the config
[15:50] <shbrngdo> so this suggests the problem goes a bit deeper, either the ppp daemon on the 'host pi' isn't fully set up when you connect 'guest pi', or something is screwy that gets fixed by re-connecting.
[15:51] <shbrngdo> can you manually insert a delay, so that you know 'host pi' is fully up and running (after a boot) before connecting 'guest pi' ? then you'll know for sure whether or not it's timing.
[15:51] <ShapeShifter499> I could have a start script that pings google then restarts PPP over and over till ping google works
[15:51] <ShapeShifter499> both Pis start up way before the Linux box does
[15:52] <shbrngdo> I actually do something "not unlike that" to restart my DNS server if the pppoe doesn't connect properly
[15:52] <ShapeShifter499> that might be the issue

[15:53] <shbrngdo> from the guest pi - if the network's primary gateway is 192.168.1.1 [a wifi router let's say] then pinging that would be sufficient

[15:54] <ShapeShifter499> the Pi couldn't connect to ANYTHING but the host pi
[15:54] <shbrngdo> but you can ssh to it... ?
[15:55] <shbrngdo> I have to wonder if your 'resolv.conf' file needs to be manually messed with when you do a ppp connection like that
[15:56] <shbrngdo> if guest pi can't connect out, then resolv.conf may not be set up for the DNS
[15:56] <shbrngdo> you could try connecting to specific IP addresses to confirm that
[15:56] * Tfid (~Tfid@unaffiliated/tfid) has joined #raspberrypi
[15:57] <ShapeShifter499> shbrngdo: ssh only worked between the guest and the host... I had to ssh into the host then I could ssh from there to the guest
[15:57] <shbrngdo> oh so re-connecting the ppp didn't fix it this time?
[15:57] <ShapeShifter499> mlelstv: do you think rp_filter is still the issue?
[15:58] <ShapeShifter499> shbrngdo: no I mean before I screwed around with restarting ppp and removing proxyarp
[15:58] <shbrngdo> yeah at this point if you've done other thigns to your config based on other people's recommendations then i don't know what state it's in
[15:58] <shbrngdo> oh well restarting the ppp probably has to do with how ppp is starting up on 'host pi' - maybe you just get there too early, or might have to "kick it" because of a bug someplace
[15:58] <ShapeShifter499> shbrngdo: I posted my current config a few posts back

[16:23] <mlelstv> when you pinged the guest, does it show up in arp or route ?

[16:24] <ShapeShifter499> mlelstv: arp -a shows all the IPs now https://gist.github.com/ShapeShifter499/c251c2621b2c15f45e40ba32f97ed0a2
[16:24] <mlelstv> if the linux host can ping the guest rpi, it either needs an arp entry or a route

[16:25] <mlelstv> hmm
[16:25] <ShapeShifter499> route does not show the IPs but arp -a does

[16:31] <ShapeShifter499> I suspected the ms-dns was the issue
[16:31] <mlelstv> unlikely
[16:32] <mlelstv> that would prevent you from using hostnames, but not ip addresses
[16:32] <ShapeShifter499> mlelstv: I just power cycled the Pis with the config changed
[16:32] <arha> also
[16:32] <ShapeShifter499> what changed?
[16:33] <arha> is there some way where the /sys/firmware/devicetree/base/model are available? (model strings)
[16:33] <ShapeShifter499> mlelstv: what do you think was the issue?
[16:33] <arha> or some other way of reliabily identifying boards across OSes? I found some bash script that processes the "revision" number in /proc/cpuinfo but that seems mostly undocumented
[16:33] <mlelstv> no idea. if it works now with the original configuration.
[16:34] <mlelstv> arha, the revision number is mostly documented.
[16:34] <ShapeShifter499> mlelstv: I changed the ms-dns to my router, I had it set to google's dns ip
[16:34] <mlelstv> you could wait 10 minutes and see if it still works :)
[16:34] <arha> ah, whoops, now i found it

[16:34] * Tenkawa (~Tenkawa@unaffiliated/tenkawa) has joined #raspberrypi
[16:35] <mlelstv> it's either magic numbers (old) or bits with specific meaning (new).
[16:35] <arha> so revision codes in cpuinfo are more portable than reading the /sys fs?
[16:35] <ShapeShifter499> I'm going to power cycle everything and my router just to be sure

[17:16] <mfa298> Owner: if you're using raspbian then the fat partition is mounted by default in /boot and apt handles the kernel updates for you.
[17:16] <Owner> ah
[17:17] <Owner> yikes....writing to a fat filesystem scares me
[17:17] <Owner> what a 'pos'
[17:17] <BCMM> which is as it should be, really. /boot/ contains platform-specific boot stuff on any normal linux distro.
[17:18] <mfa298> similar to how it works on most other linux distros, (except raspbian only keeps a single kernel version around as there's no bootloader like lilo or grub involved to let you choose a kernel)

[17:19] <Owner> you guys are experts
[17:19] <mfa298> Owner: FAT's been around for decades and well documented so is fairly safe to use (also keep it family friendly - even with the abreviations)

[17:21] <mfa298> this probably isn't the place to ask about u-boot, putting that in the middle is a non standard setup so very few will know about what it can do. But FDE isn't a common setup and doesn't fix the problem most people seem to want it for.
[17:21] <ShapeShifter499> I don't know of anything up in the 200s of my IP address

[20:02] <mijk> hey, so I have an old Cisco 7941 and the LCD screen ribbon cable appears to be wide enough to fit the connector on the Pi Zero W. It's only 4 bit grayscale at 320x222 though. Will it still be able to display the command shell?
[20:03] <leftyfb> mijk: if it's not using DSI, then it will not work
[20:04] <leftyfb> mijk: just because the connector fits, doesn't mean it's the correct wiring or protocols. You can do damage assuming so and plugging things in
[20:04] <mijk> if I fits, I sits
[20:04] <mijk> no, not assuming which is why I ask
[20:05] <mijk> ew50680fr is the model of this LCD
[20:06] <IT_Sean> I can pretty much guarantee it is highly unlikely to work.
[20:07] * energizer (~energizer@unaffiliated/energizer) Quit (Ping timeout: 260 seconds)
[20:07] <mijk> well that sucks
[20:08] <IT_Sean> Sorry. But the factory ran out of magical unicorn and pixie dust, so, for now. The operating parameters of all Raspi devices are rooted in reality.
[20:08] * Singmyr (~singmyr@80.216.49.44) has joined #raspberrypi
[20:08] <mijk> well, you don't have to be sarcastic about it. it's a simple question...
[20:08] * mijk (~quassel@67-204-252-161.eastlink.ca) has left #raspberrypi
[20:09] <shbrngdo> I wonder what kind of damage would be done to the RPi if the wrong connecter were plugged in for LCD
[20:09] <ShorTie> only the smoke knows
[20:10] <shbrngdo> would it render the RPi unusable? or would it JUST be unusable for the right kind of LCD
[20:10] <IT_Sean> shbrngdo: depends. I would imagine that some of the connectors getting bridged would probably be ungood.
[20:10] <IT_Sean> I wouldn't try it with ha Pi or a display I cared about.
[20:10] <IT_Sean> s/connectors/contacts
[20:10] <shbrngdo> it would depend on a lot of things for sure. I just wonder if the RPi would be completely useless afterwards
[20:11] <IT_Sean> Again, it depends. Unlikely, but, you might kill e dsi port, or the display.
[20:11] <shbrngdo> I was working on something work-related over a decade ago, that required GPIOs be brought out to control an antenna. The eng tech accidentally wired one wrong, and it fried that pin. I was still able to use it for development, though [with a known bad GPIO pin]
[20:11] <shbrngdo> but yeah it was completely useless as a functioning unit
[20:12] <shbrngdo> but yeah I'd hate to think that "make one mistake and you fry it" is something to be overly concerned about with RPi
[20:12] <IT_Sean> I once fried a very expensive (in terms of R&D) prototype board when I accidentally dropped a paper clip on it, and bridge a 48vDC supply pin with a 3.3vDC signal pin.
[20:12] <IT_Sean> Released quite a lot of magic smoke.
[20:12] <Tenkawa> IT_Sean: ouch
[20:13] <IT_Sean> There were only two copies of that board in existence at the time, too.
[20:13] <shbrngdo> yeah I had that happen the other day, when I went to test something with a 5v LCD on it. I had the wires plugged into + and - on the bench power supply instead of + and ground, so the voltage was actually 10v, not 5v. oops.
[20:13] <Tenkawa> i was about to ask how much smoke and sparking that made.. I've seen that happen to a board
[20:13] <Tenkawa> it is not a good sight
[20:13] <IT_Sean> Tenkawa: my office smelled weird for several weeks.
[20:14] <Tenkawa> a melted cap is bad enoough
[20:14] <Tenkawa> er enough
[20:14] <shbrngdo> the LCD didn't smell but it behaved oddly when it was powered up. I have a few things that I can plug those into, and so I swapped it for a known good one and observed the oddness. $10 into the trash
[20:14] <Tenkawa> and I've been through many of those (capacitors)
[20:14] <IT_Sean> I also once had a new (new to us, read: used) Cisco switch blow up upon power up once. Main filter caps on the power supply went ballistic.
[20:14] <Tenkawa> ouchie
[20:15] <IT_Sean> My ears were ringing for a while.
[20:15] <Tenkawa> now transformers truly scare me if they are big enojgh
[20:15] <Tenkawa> er enough
[20:15] <shbrngdo> yeah they're like mini-bombs depending (like the first one I ever blew up had shredded paper going everywhere)
[20:15] <IT_Sean> Apparently the seller failed to mention it had a non-global power supply in it,cans it was intended for 240v service.
[20:15] <IT_Sean> *and
[20:16] <IT_Sean> I didn't like being fed 120vAC
[20:16] <shbrngdo> I've never had a transformer blow up. smoke and short out (then open) internally, several times
[20:16] <Tenkawa> I always preferred working with 240v... dont know why
[20:16] <IT_Sean> Most residential and office service here is 120v
[20:16] <IT_Sean> 240v is reserved for large appliances.
[20:17] <shbrngdo> USA is all 120v except for split-phase and 3 phase systems
[20:17] <IT_Sean> Hat ^
[20:17] <IT_Sean> *that
[20:17] <Tenkawa> shbrngdo: I've been around at least a few that made a good acoustic impression
[20:17] <shbrngdo> split-phase 210/220 typically powers large equipment, ovens, and clothes dryers
[20:17] <Tenkawa> IT_Sean: not completely....
[20:17] <Tenkawa> yeah
[20:18] <IT_Sean> No, there are exceptions, but... Most service here is 120v, unless otherwise noted or socketed.

[20:19] <shbrngdo> you can't plug the wrong thing into it
[20:20] <ShorTie> they are configured by amperage rating
[20:20] <IT_Sean> Now, there are exceptions. I've been in plenty of data enters where they are running 240 on 120 -style outlets. But it's usually labeled. ...usually

[20:21] <IT_Sean> HA!
[20:22] <ShorTie> no, the blades are the opposite direction
[20:22] <shbrngdo> I've seen them try to plug vacuum cleaners into power strips that have computers on them. I gently suggested PLEASE do NOT plug a motorized piece of equipment into a power strip with a line filter on it

[20:22] <ShorTie> got them every where around here

[20:23] <shbrngdo> yes but a line filter designed for motors is fine. a line filter in the averag power strip can't handle the continuous spiking
[20:23] <IT_Sean> We had a maid service at $job.old that started unplugging PCs to plug in e vacuum.
[20:23] <shbrngdo> ew. worse.
[20:23] <IT_Sean> I cut off the end of the vacuum plug every time I caught them doing it.
[20:23] <IT_Sean> They fairly quickly learned
[20:24] <shbrngdo> I'm just concerned about a) the vacuum motor ruining the filter, and b) the computers being exposed to the spiking because they're all on the same bus as the vacuum, now [not filterd]
[20:25] <shbrngdo> the filter is really designed to filter power from the wall socket to the computer, NOT things on the popwer strip to one another
[20:25] <shbrngdo> and of course every one of the vacuum cleaners [necessarily] has an AC/DC motor with brushes in it [arc, spark, surge]

[21:12] <darsie> Charge a mosfet gate with a resistor?
[21:12] <shbrngdo> MOSFET gate capacitance is so tiny it's like a non-issue. but a series resistor is an ok idea for noise abatement
[21:13] <shbrngdo> one way to mitigate unintentionally radiated RF noise is to put small series resistors on GPIO pins, like 47 ohms

[21:14] <Owner> i dont know why the file was missing though after a fresh setup :/
[21:14] <Owner> just a .txt
[21:14] <shbrngdo> imperfect image?
[21:14] <stiltr> Seems like some distros don't package the .txt file.
[21:14] <stiltr> Not sure if there's a reason.
[21:14] <shbrngdo> might be a licensing thing - note the 'non-free' in the URL

[21:15] <stiltr> Ya, that seems reasonable, shbrngdo.
[21:15] <Owner> just not sure why it was missing
[21:15] <shbrngdo> a lot of linux distros are like that, Debian / Raspbian being one of them. If it's not GPL, they put it into "non-free" and don't ship pre-installed

[22:56] <DexDeadly> Hey All! I have a question when it comes to the GPIO pins. This might even be a python question but thought I'd try here first. I'm working with a float switch connected to a GPIO pin. I have it set so that when the GPIO.FALLING occurs it triggers a notification
[22:56] <DexDeadly> now I set the bounceback but I'm having trouble trying to find something out.
[22:57] <DexDeadly> I know that when I set the bounceback it will not run the event listener for that many milliseconds. However, my question is, if my float switch is to deactivate I'd like to know if it was to reactivate again is the bouncetime still in effect or will it regtrigger

[23:00] <DexDeadly> Example, float switch triggers, bounceback set to not check for 5 mins. I reset float switch by filling the water backup and the switch will then be deactivated. However if within that 5mins the float switch happens to retrigger will it not reactivate due to the bounceback timer not reaching 5mins
[23:00] <stiltr> I don't know the specifics of your GPIO library, but you might try this: After your switch triggers, set a variable and change to watching for a rising edge. Then change back on the next trigger, etc.

[23:11] <DexDeadly> hey stiltr, yea more then likely i'm going to just have a check of every one min after bounceback. The float switch is going to be to check the water level in an automatic top off bucket for my fish tank

[23:22] <DexDeadly> basically yea
[23:23] <DexDeadly> It is going to be in a bucket that will fill my sump by gravity. I want to monitor that buckets water level. So it'll be normally opened and then once it hits a certain level the float switch will close and notify me
[23:23] <ShorTie> why so long of debounce if i may ask ??
[23:24] <gordonDrogon> run it via cron once a minute. forget debounce - it's if low, turn on the tap.
[23:24] <DexDeadly> the 5 mins? that was just an example
[23:24] <DexDeadly> no tap
[23:24] <DexDeadly> gravity fed ato
[23:24] <DexDeadly> im just monitoring the levl in a bucket
[23:25] <stiltr> I think there are two times that might be getting confused. Polling time and debouncing time. Polling time may be every minute or whatever. Debouncing time is likely <1second. (Depending on the switch)
[23:25] <ShorTie> think he is suggesting to add a valve in the pi can open to fill the bucket
[23:26] <DexDeadly> I'll manually be filling the bucket
[23:26] <DexDeadly> I'm just going to notify myself when it gets low
[23:26] <ShorTie> �k�� ��K��
[23:26] <DexDeadly> GPIO.add_event_detect(24, GPIO.FALLING, callback=float_switch, bouncetime=300000) my test was this
[23:27] <DexDeadly> so once triggered dont do anything for 5 mins. What my question was is if the GPIO pin was reset and then triggered again in 5mins would it actually trigger
[23:27] * pavlushka (~pavlushka@ubuntu/member/pavlushka) Quit (Read error: Connection reset by peer)
[23:27] <DexDeadly> For simplicity I think the best bet is to use a variable as stiltr suggested.
[23:28] <stiltr> So once it's triggered (and debounced) the GPIO will be reading high. So if you're only looking for a rising edge, you won't see one.

[23:29] <stiltr> I got my polarities swaped, but the idea holds.

[23:53] <programmerq> I ordered a couple raspberry pi 3 B+ units. Niether one of them will make it to the rainbow screen. There's simply nothing being output over HDMI. It acts the same whether I've got an SD card installed or not. I've also tried two different power supplies and two different monitors.
[23:53] <programmerq> it seems strange that I'm having the same problem on both so I'm guessing I've missed something simple

[23:55] <ShorTie> what image are you writing ??
[23:55] <programmerq> The red PWR light comes on, and that's it.
[23:55] <programmerq> latest raspbian as downloaded yesterday.
[23:56] <ShorTie> and you unzipped it ??
[23:56] <programmerq> yes, lol

[23:57] <ShorTie> some have been known not too, Sorry
[23:57] <programmerq> it's all good. gotta double check the basics for sure.
[23:57] <programmerq> popping the card into another computer confirms that the partition table was written out as I'd expect.
[23:58] <programmerq> it did, however, take a very long time.
[23:58] <programmerq> like 6 hours to write the 4.5gb image.
[23:58] <ShorTie> what dtb files are there
[23:58] <programmerq> which seemed wrong

[23:58] <ShorTie> ya, thats no good
[23:58] <mfa298> that might indicate a really bad sd card
[23:59] <stiltr> Could be the card is on the way out.
[23:59] <ShorTie> what are you using to write it with ??
[23:59] <programmerq> dd on mac os
[23:59] <ShorTie> no windows around ??
[23:59] <programmerq> well, yes but to what end?
[23:59] <mfa298> did you add a 'bs=' flag to dd (I normally use bs=4M)
