[0:49] <Smeef> The fuel gauge isn't an option because I'm already using the Powerboost 1000C to charger the patter, power the pi, and start and safely shutdown the pi on low battery. There's an LBO pin on the Powerboost that connects to GPIO 15 and tells the Pi when the battery is low and triggers the safe shutdown script. Is there a way to read the voltage on GPIO 15 so I can monitor the voltage and come up with an algorithm to display a percentage of power

[0:55] <Smeef> Thanks
[0:55] <stiv> you should get an ADC!

[2:12] <jetole> Hi guys. I have a few pi's here and I'd like to get more but I am having a hard time doing a headless install I can SSH into. It seems if I create the empty ssh on the pi, I get a prompt about only being able to log w/ kb interactive or with a key but there is no key on the pi yet. I'd prefer to put a pub key on the raspbian image but don't know how and can't find a doc. I've tried some different pi image builder kits with little success and was
[2:12] <jetole> about to start looking at the noobs docs but I am reaching the point where I am starting to get fed up just being able to get a headless install. Of I did get the wpa_supllicant working but anyways, once I get a headless basic system I can Ansible the hell out of it but can someone help me just getting a headless system? Right now I have a few pi zero w's and 6 pi 3b's

[2:15] <kerio> you're flashing the image
[2:16] <kerio> mounting it is like a quarter of a step further
[2:16] <jetole> OK... yes I tried that on the stretch image. After it booted the files I put in home (auth keys, etc) weren't there. It's like it redeployed /home

[2:51] <MrBusiness> Has anyone ever experimented with integrating a TPM with a Raspberry Pi? I've seen some vague hints that people may have done some interesting things with this.

[2:56] <MrBusiness> Okay, I'll relay any links that I find.
[2:56] <MrBusiness> At the moment I'm trying to find a good case for a Threadripper X399 motherboard that isn't cursed with tons of tempered glass
[2:56] <MrBusiness> I can't see how it offers any kind of improvement over lightweight acrylic.
[2:57] <MrBusiness> I mean, with acrylic you can take a drill and hole saw and cut out some frankenbox fan ports.

[2:58] <MrBusiness> Wonder if somebody will make some ridiculous RGB modded Pi with a custom-blown tempered-glass case. T'would be absurd.
[2:58] <MrBusiness> I'm also looking into using Pis as an interface to a larger desktop to act as a sort of TPM-alike.
[2:58] <Kryczek> MrBusiness: this summer I bought a CoolerMaster Cosmos II (the original one, not the Anniversary edition or the other one) exactly for that reason
[2:58] <MrBusiness> Yeah
[2:58] <Kryczek> no window whatsoever
[2:58] <MrBusiness> That's what I'm thinking of now
[2:58] <Kryczek> and it looks so beautiful
[2:58] <Kryczek> brushed aluminum
[2:59] <MrBusiness> I was thinking about the CM Storm Trooper
[2:59] <MrBusiness> but then I learned that XL-ATX and E-ATX are not the same dimensions
[2:59] <Kryczek> I didn't know of that one... looks pretty nice too!
[3:00] <Kryczek> yeah and iirc at least one of those two is not standardized
[3:00] <MrBusiness> Yeah, I really like the handle and the hidden toolkit.
[3:00] <Kryczek> so there might be more than one "XL-ATX" or "E-ATX"
[3:00] <MrBusiness> They seem to be standard form factors
[3:00] <MrBusiness> I've also seen EE-ATX, but I can't tell if that was a type or what
[3:00] <Kryczek> I bought an ASUS Z270-WS which is simply ATX but I wish they had gone bigger, it could have used more room
[3:01] <MrBusiness> and then there's the EVGA Classified SR-2 motherboard, which is a dual-CPU mobo that apparently has a form factor far larger than anything that came before. Probably requires a desk enclosure or a 1U rack.

[3:02] <Kryczek> oh wow
[3:02] <Kryczek> yeah that's special :D
[3:02] <MrBusiness> Yeah. It's a dinosaur by now, but I imagine that there must be SuperMicro or JetWay boards that come close to this size
[3:02] * TReK (~UnFaQ@unaffiliated/trek) Quit (Ping timeout: 248 seconds)
[3:03] <Kryczek> well that's a whole new category, hard to compare
[3:03] <MrBusiness> I've been scouring for a good SuperMicro with a Xeon SoC and TPM 2.0 on an mITX platform, but thus far I've come up dry.
[3:03] * WARlrus (~freenode@home.mattdyson.org) Quit (Ping timeout: 260 seconds)
[3:03] <MrBusiness> then, in the opposite direction, ASRock apparently invented the mini-STX
[3:03] <MrBusiness> which uses laptop MxM slot laptop GPUs
[3:03] <Kryczek> ~10 years ago I procured NVIDIA Tesla racks (which didn't have any CPU in it, just GPUs with external PCIe connectors) and for them I chose SuperMicro racks, of which you could fit two side by side in 1U
[3:04] * mutex86 (~Mutex@aftr-109-91-35-158.unity-media.net) has joined #raspberrypi
[3:04] <Kryczek> MrBusiness: be careful that TPM2.0 is completely different from TPM1.x
[3:04] <MrBusiness> nice
[3:04] * WARlrus (~freenode@home.mattdyson.org) has joined #raspberrypi
[3:04] <MrBusiness> Yeah, but it offers better hashing
[3:05] <MrBusiness> Almost tempted to see what Gigabyte is offering in the way of X399 TR4s
[3:05] <Kryczek> MrBusiness: I actually bought a TPM2.0 module for that ASUS Z270-WS and shortly thereafter also bought a TPM1.2 module because it was just too much of a PITA to get TPM2.0 working
[3:05] <MrBusiness> since Gigabyte apparently engineered something they call the "Ultra TPM" which can do 2048-bit crypto, and includes some (probably Windows-only) software that lets one destroy the key on a TPM to make data forever inaccessible without having to physically smash SSDs or wipe HDDs
[3:06] <MrBusiness> Was it made for TPM 2.0?
[3:06] <Kryczek> TPM1.2 already has RSA 2048
[3:06] <MrBusiness> ah, hm
[3:06] <Kryczek> the hashing difference is SHA1 in TPM1.2 and SHA256 plus maybe others in TPM2.0
[3:06] * TReK (~UnFaQ@unaffiliated/trek) has joined #raspberrypi
[3:06] <MrBusiness> One article I wish I could dredge back up was someone discussing building a custom cryptoprocessor out of a PCIe FPGA, it had an absurd bitdepth, assuming it was true and actually worked.
[3:07] <MrBusiness> Yeah, that much I know
[3:07] <MrBusiness> and I like that quality.
[3:07] <Kryczek> tpm_getpubek on my 7 year old Dell laptop right now for examples gives me: Key Size: 2048 bits
[3:07] <MrBusiness> I mean, I'm not gonna use just one cryptoprocessor
[3:07] <MrBusiness> I'm also gonna use a YubiHSM2
[3:07] <MrBusiness> from Yubico, the makers of Yubikeys.
[3:07] <Kryczek> I know them :)
[3:07] <MrBusiness> Which I think is an offshoot of the hakshop, run by the Hak5 people
[3:08] <MrBusiness> who came out with two new tools I need to get while they're on sale.
[3:08] <Kryczek> I don't have a yubisomething (yet?) but I have a Nitrokey Pro which is sort of the same, and I use it one machines that don't have a TPM
[3:09] <Kryczek> MrBusiness: key size is not everything
[3:09] <Kryczek> let's say that FPGA was doing RSA 8192 for example
[3:09] <MrBusiness> yeah, I mean, if the key is too big for practical everyday use then it's nuts
[3:09] * Dojka_ (~Dojka@dhcp-108-168-85-234.cable.user.start.ca) has joined #raspberrypi
[3:09] <Kryczek> I would bet it would be easy to circumvent when the OS has to load the "firmware" into the FPGA etc
[3:10] <MrBusiness> I mean, from what I gather, it would already take a lifetime with extant hardware to break a 4096-bit PGP key
[3:10] <MrBusiness> Yeah, having the FPGA tied to the PCIe BUS probably weakens it to a degree.
[3:10] <Kryczek> whereas a proper factory-made Hardware Security Module (HSM) like in the Nitrokey, some (?) Yubikeys and all TPMs (except for the recent ROCA embarrassment...) keeps the private key in hardware forever
[3:11] * Dojka_ is now known as Dojka
[3:11] <Kryczek> MrBusiness: it's not the bus itself that's the problem, I mean: Yubikeys and Nitrokeys use USB for example which is arguably more exposed than PCIe
[3:12] <Kryczek> I was referring to the fact that the FPGA's firmware is most likely not protected
[3:12] <MrBusiness> Nitrokeys, eh?
[3:12] <MrBusiness> I gotta look those up
[3:13] <Kryczek> I have this one https://www.nitrokey.com/products/nitrokey-pro
[3:13] <Kryczek> there are newer models now, maybe they are better for your particular use case
[3:13] <MrBusiness> I could also probably make some sort of custom verification stick out of one of my keypad-locked Aegis 8GB AES256 USB sticks
[3:13] <Kryczek> the one called Nitrokey HSM has a confusing name though: it's not the only HSM (e.g. the Pro is an HSM too)
[3:13] <MrBusiness> interesting
[3:13] <MrBusiness> so it's a key and an HSM
[3:13] <MrBusiness> very intriguing
[3:13] <Kryczek> no no
[3:14] <Kryczek> some of the newer ones have storage like a USB thumbdrive
[3:14] <MrBusiness> The crypto activation dongle for the forthcoming ORWL mini s@\(C\)\(ubes\)@Q\2@<esc>:AOS<esc> machine looks interesting as well.
[3:14] <Kryczek> the Pro is 100% a hardware security module, no storage
[3:14] <MrBusiness> I suspect it's based mainly on NFC
[3:14] <MrBusiness> Interesting
[3:14] <Kryczek> ah yeah I heard of it
[3:15] <MrBusiness> My original goal was to use a USB Rubber Ducky with a specific payload and firmware, as well as maybe some kind of small VeraCrypt installation to make an automatic, encrypted password manager, but two such devices have already hit the sales floor of CrowdSupply.
[3:16] <Kryczek> to have it type decrypted passwords directly as if it were a keyboard?
[3:18] <Kryczek> I wish HTTPS Client Certificate Authentication hadn't been ruined
[3:18] <MrBusiness> yeah
[3:18] <Kryczek> it would have been perfect with HSMs
[3:18] <MrBusiness> There are two of them
[3:18] <MrBusiness> one made in the USA, the other in Russia
[3:19] <Kryczek> so... you have to buy both and give half of each password to NSA and the other half to KGB? :P
[3:19] <MrBusiness> I'm gonna try both, but I have severe misgivings with the notion of using something built in Russia given all the FUD in the news about Russia owning things like the US Government Employee Database.
[3:19] <MrBusiness> Pretty much
[3:19] <MrBusiness> but I mean
[3:19] <MrBusiness> consider this
[3:19] <MrBusiness> does the Pi have some kind of GCHQ backdoor?
[3:19] <MrBusiness> MI-5?
[3:20] <Kryczek> haha
[3:20] <MrBusiness> I mean, I've observed some strange behaviors in my old Pi B+-es
[3:20] <Kryczek> I pity whatever GCHQ staff who might now be frustratingly waiting for me to plug in all the RPi's that I have gathering dusts
[3:20] <MrBusiness> Like, the man pages and help dialogs seem to differ, or differed at the time, depending on whether or not I had an ethernet cable connected.
[3:21] <MrBusiness> Yeah. But now that they have onboard BT and Wifi, who knows what they might be capable of.
[3:21] <Kryczek> I'm not saying it was aliens, but...
[3:21] <Kryczek> :P
[3:22] <MrBusiness> Either way, my next applications of Pis will be to make some that do RetroPi, complete with classic game console cases
[3:22] <MrBusiness> oh god, don't mention aliens, please
[3:22] <MrBusiness> I got hacked hard in Dec 2014
[3:22] <Kryczek> by aliens?
[3:22] <MrBusiness> like, the fuckers were watching me through my phone, and then due to bad password policy they owned roughly 5 computers.
[3:22] <MrBusiness> No, some company or group of people from companies in CA
[3:23] <MrBusiness> I apparently called down the lightning on myself.
[3:23] <Kryczek> so... illegal aliens?
[3:23] <MrBusiness> no, they were typical white, 20-40-something californians.

[3:24] <MrBusiness> "My Unbelievable Experience"
[3:25] <MrBusiness> so I'll just offer you a copy of the text file when I'm done writing the tale.
[3:25] <Kryczek> no thanks
[3:25] <MrBusiness> I think I've figured out most of what happened and why, but they were careful to orchestrate the whole thing such that I ended up looking insane as a result.
[3:25] <Kryczek> I already have enough aliens with Fox Mulder
[3:25] <MrBusiness> The aliens bit came about

[3:26] <nolsen> How do I get my port back.
[3:27] <nolsen> I need it for dnsmasq

[3:27] * Ilyas (uid43013@gateway/web/irccloud.com/x-jcgsyghbqqkoraup) Quit (Quit: Connection closed for inactivity)
[3:27] <MrBusiness> But you'll never know fear until you watch an htop listing of a /dev/3g:<random socket number> appear, and then, as a result, lock down your BIOS with a 1-50 character password while still in Ubuntu.
[3:27] <MrBusiness> Never buying another Toshiba ultrabook with a cellular connection, that's for sure.
[3:28] <Kryczek> nolsen: hopefully it is only bound to 127.0.0.1, so maybe an easy workaround is to make dnsmasq listen to a specific external IP (like 192.168 something) at the same time
[3:28] <MrBusiness> Do need to make a router with a 4GLTE antenna though, for phones to connect to a mitM-ed wifi access point that'll wireshark all incoming connections.
[3:28] <Kryczek> wireshark has too many memory leaks
[3:28] <nolsen> Kryczek: I don't even have it installed.
[3:29] <nolsen> resolved is not istalled
[3:29] <nolsen> installed
[3:29] <nolsen> So why would it take 53
[3:29] <Kryczek> not resolved
[3:29] <Kryczek> systemd-resolvd
[3:29] <Kryczek> see `sudo netstat -nltup`
[3:29] <nolsen> unrecognized service
[3:29] <Kryczek> eh?
[3:29] <Kryczek> what does netstat say
[3:29] <nolsen> udp 0 0 localhost:domain 0.0.0.0:* 1/systemd
[3:29] <MrBusiness> yeah, since I was thinking that I'd make my packet analysis machine a 7" touchscreen Pi, I might just use pcap and logrotate to store pcap files for later review in Wireshark, as I imagine that would be easier than trying to automate Wireshark.

[3:42] <Kryczek> nolsen: it's part of the systemd package
[3:42] <MrBusiness> Rather build some kind of controller based on a Pi Zero W that works similarly to the GoPro 3 Remote. A little 3.5" LCD, some basic buttons, and exposed USB for the auth factor keys, whatever they may be.

[5:53] <[Saint]> ZorroT: doesn't Rotate take an integer?
[5:53] * mossman93 (~mossman93@unaffiliated/mossman93) has joined #raspberrypi
[5:54] <[Saint]> ie. 0, 90, 180, etc
[5:54] <ZorroT> i'll give it a try :-)
[5:54] <[Saint]> perhaps I'm misremembering.
[5:55] <ZorroT> maybe or not -- this is the first instance where the command has caused the framebuffer to do anything other than work :-)
[5:56] <[Saint]> yay, I guess? Ha.
[5:56] * taza (~taza@unaffiliated/taza) Quit ()
[5:56] <ZorroT> i've got a green framebuffer, but no display
[5:57] <ZorroT> but, for what it's worth, it's the first change that's actually had any effect, so... maybe good.
[5:58] * jdawgaz (~Jerry@ip70-176-27-239.ph.ph.cox.net) has joined #raspberrypi
[5:59] <ZorroT> this is maddening. xrandr doesn't want to help, x server doesn't seem to want to help. nothing fails, just... nothing works. :-)
[5:59] <[Saint]> if x/y res is hardcoded, it may be out of bounds w/ rotation set?
[6:00] <ZorroT> it's possible. the rotation option is a value, not a matrix.
[6:00] <ZorroT> so maybe it's rotated correctly and offscreen
[6:00] <[Saint]> xrandr can go screw itself.
[6:00] <ZorroT> i'm friendly to any software that will fix this problem :-)
[6:00] <[Saint]> multi-hotseat is unreasonably difficult with it.
[6:00] <ZorroT> "yes, this would be better in portrait mode. how hard can it be?"
[6:01] <ZorroT> in my case, i have an external usb monitor that i want to rotate the output on 90 degrees.
[6:01] <ZorroT> i've not had this much resistance to doing things my way since I had a mac :-)

[7:37] <eklavyaa> sorry I mean, I have windows desktop and got a raspberry pi 2
[7:37] <GeekOfflineNL> yes...
[7:37] <eklavyaa> how can I start programming raspi
[7:37] <eklavyaa> which toolchain set I need
[7:37] <GeekOfflineNL> just hook an keyboard, mouse, power and a monitor to the raspberry pi
[7:37] <eklavyaa> but it doesnt have any software loaded onto it
[7:38] <GeekOfflineNL> use windows to flash an microSD card
[7:38] <eklavyaa> ok
[7:38] <eklavyaa> which OS to load?
[7:38] <GeekOfflineNL> let me look for a link eexplaining it
[7:38] <GeekOfflineNL> step by step
[7:39] <eklavyaa> ok thank you
[7:39] <GeekOfflineNL> https://www.cnet.com/how-to/how-to-get-started-with-the-raspberry-pi/
[7:39] <GeekOfflineNL> start with the raspbian image

[7:44] <GeekOfflineNL> goodluck
[7:44] <eklavyaa> can I use raspberrypi as a lean system to run cyber cafe?
[7:44] <GeekOfflineNL> eklavyaa, probably, only browser performance is a little bit slow

[7:45] <GeekOfflineNL> eklavyaa, that would work
[7:45] <GeekOfflineNL> but why a pi2? pi3 has wifi build in
[7:46] <aib> hmm, maybe it was NOOBS with Raspbian installed https://www.raspberrypi.org/documentation/installation/noobs.md
[7:46] <eklavyaa> I had purchased pi2 couple of years ago and could not use it much
[7:47] <aib> ah "As of NOOBS v1.3.10 (September 2014), only Raspbian is installed by default in NOOBS'

[12:48] <Encrypt> I have a question for you regarding the SWAP on the Pi
[12:49] <Encrypt> According to you, is it better to add a SWAP partition or to use a text file as SWAP space?
[12:49] <ShorTie> raspbian comes with swap as a file
[12:50] <Encrypt> ShorTie, Yeah

[12:57] <mfa298> on spinning rust swap partition was potentially wise as you could tune the drive for speed (most used partitions at the faster end) although I'm not sure how many people bothered with that.
[12:58] <mfa298> but that doesn't really apply for the flash based storage these days.

[13:31] <aliasunknown> We have been using this design for a few years now without issues like this

[13:32] * SopaXorzTaker (~SopaXorzT@unaffiliated/sopaxorztaker) has joined #raspberrypi
[13:32] <aliasunknown> We thinking about adding a fuse so then maybe it wont burn the pi
[13:32] <aliasunknown> my "feeling" is that the USB and devices are drawing to much power
[13:33] <aliasunknown> our PCB has a serial GPRS modem and the pi + usb powered by a 5A DC-DC converter
[13:33] <aliasunknown> i think the converter doesnt have enough power and/or devices are drawing from the pi
[13:33] <aliasunknown> ive been working for months using a benchtop power supply and never burned anything
[13:34] <aliasunknown> only recently with this DC-DC converter and usb hub have I been burning pies up
[13:34] <ShorTie> self powered hub ??
[13:35] <aliasunknown> Ive worked with out the DC converter and with the hub with some odd behavior, like reboots but never any smoke
[13:35] <aliasunknown> it "IS" but I know it still draws from the pi from some tests I made a few years ago
[13:35] <aliasunknown> I ordered a "valid PI USB hub" but it came DOA so im waiting for another one
[13:37] <ShorTie> ebay has some cheap relay boards for the pi with opto couplers built in
[13:37] <aliasunknown> *it is a self powered hub but it is not being externally powered
[13:37] <ShorTie> what good does that do ??
[13:38] <aliasunknown> Not much but we figured we are just using a small nano bluetooth and serial converter
[13:38] <aliasunknown> so it wont draw too much

[13:38] <aliasunknown> im starting to get the feeling that was a bad idea?
[13:39] <aliasunknown> But then again, if the problem is the hub not being powered then why did it work fine when I was using the benchtop PSU?
[13:39] <ShorTie> i'd power the hub, then power the pi from the hub
[13:40] <aliasunknown> Is it safe to connect the pi on 2 ports?
[13:40] <aliasunknown> one for power and the other for comms?

[13:43] <ShorTie> sure the 5v output is being held steady ??
[13:43] <ShorTie> those convertor output can very with battery voltage input
[13:44] <aliasunknown> I can't say im 100% sure but I have measured with and without load

[13:47] <aliasunknown> but we dont need it for the current short term project
[13:48] <aliasunknown> i dont have any 5V power supplies laying around

[14:29] <SirLagz> Habbie: https://i.imgur.com/SHPOJo0l.png it's a bit small
[14:29] <Habbie> what's this, sudo for ants
[14:29] <SirLagz> heh
[14:29] <Habbie> so those '' quotes
[14:29] <Habbie> the shell removes those for you
[14:29] <Habbie> your logs will tell you what sudo actually saw
[14:29] <SirLagz> http://i.imgur.com/SHPOJo0.png <-- there's a bigger one
[14:30] <SirLagz> Habbie: I have no idea where sudo logs to...
[14:30] <Habbie> on a sidenote, logging to /tmp is a great way to help users elevate themselves to root
[14:30] <SirLagz> Habbie: ah found it
[14:31] <Habbie> auth.log on my box
[14:31] <SirLagz> Habbie: how does logging to /tmp help users elevate themselves to root?
[14:31] <SirLagz> Habbie: also, just a temporary measure for now.
[14:31] <Habbie> because if a user knows you are going to do this
[14:31] <Habbie> and the file does not exist yet
[14:31] <Habbie> a user can symlink it to somewhere else
[14:32] <Habbie> and you will start logging to that 'somewhere else'
[14:32] <Habbie> overwriting what was there or appending to it
[14:32] <SirLagz> hmm
[14:32] <Habbie> then if they can convince your hostapd to log something useful, say, a newline followed by an extra root account for /etc/passwd
[14:32] <Habbie> they're in
[14:32] <Habbie> and even if they can't do that, they can do damage
[14:33] <SirLagz> well, yeah I can see htem doing damage...I wonder if hostapd runs as root...
[14:33] <Habbie> let me check
[14:33] <Habbie> i have one
[14:33] <Habbie> yes
[14:33] <Habbie> mine runs as root
[14:33] <SirLagz> ah
[14:33] <SirLagz> yes. that will definitely be changed before I push this out then
[14:34] <Habbie> the good news is that as root you can just go into /var/log
[14:34] <SirLagz> Habbie: that is true.
[14:34] <SirLagz> Habbie: I'll fix that up later
[14:34] <Habbie> why not let it syslog though?

[14:34] <Habbie> yes, let's go back to your problem
[14:34] <SirLagz> using /tmp was useful so I could empty it without root or sudo :P
[14:34] <redrabbit> so its privilege escalation, but you need to have a shell as a user already right

[14:40] <Habbie> then i do want to go back to my other question
[14:40] <Habbie> why not syslog?

[14:42] <SirLagz> Habbie: slightly messier
[14:42] <Habbie> are you sure?
[14:42] <Habbie> you could configure syslog to make a separate hostapd log file even
[14:42] <SirLagz> Habbie: that's also true...but then to enable/disable logging for hostapd, I'd need to mess with syslog
[14:42] <SirLagz> Habbie: more things to go wrong there...I'd rather just mess with hostapd
[14:42] <Habbie> isn't it enabled already?

[14:46] <Habbie> can confirm it's just that one
[14:46] <Habbie> oh it died
[14:46] <Habbie> this is fun
[14:47] <SirLagz> Habbie: just adding the -f switch makes hostapd log more to a file so that's why I was going that way
[14:47] <Habbie> oh it logs -more-, ok
[14:47] <Habbie> any reason to not just do that all the time?

[14:51] <Habbie> make sure you let sudo limit env vars as it does by default
[14:52] <SirLagz> only thing I'm changing in sudoers is the commands
[14:52] <SirLagz> which really should go in its own file...which it will eventually
[14:52] <Habbie> well, yes, but now you're giving your webapp permission to run a script
[14:52] <Habbie> which means a shell is involved
[14:52] <Habbie> which means environment variables may affect behaviour
[14:52] <Habbie> if an attacker gains control over your webapp
[14:54] <SirLagz> well. theoretically, the user won't know where this script is or how to run it
[14:54] <SirLagz> so there's some security by obscurity there
[14:54] <Habbie> if he compromises the webapp, he'll find out :)
[14:54] <SirLagz> that's also true
[14:54] <Habbie> when considering security, always assume there are no secrets other than your passwords

[15:33] <gordonDrogon> the current limiter on the b+ onwards will stop you at 1.2 amps too.
[15:34] <shiftplusone> aye. So to get to 3 amps, you'd have to try to draw it from the 5V gpio pin, but that wouldn't work anyway.
[15:34] <leftyfb> filadome: what exactly are you trying to accomplish?
[15:34] <filadome> i found a 5v 3A power supply with a 2.1x5.5 jack
[15:34] <filadome> i was able to use a few adapters to connect it to USB micro
[15:35] <filadome> the question is, would the cable overheat
[15:35] <filadome> if you say it's only 1.2A, then possibly not
[15:35] <leftyfb> it will be fine
[15:35] <filadome> 3A from a tiny usb micro jack seems either the maximum or more than maximum
[15:35] <leftyfb> just don't try to draw 3A from the pi itself

[15:38] <gordonDrogon> you can plug them in, but 1.2A is all you'll get.
[15:38] <filadome> how much current does the Pi by itself?
[15:38] <filadome> can it run from a regular USB port?
[15:39] <gordonDrogon> it might run - it will depend on the port and the device.

[15:39] <gordonDrogon> it needs a bit more to boot than to run though, so startup is key.

[15:40] <shiftplusone> 0.5A
[15:41] <shiftplusone> So if you take spikes into account, I'd expect some hardware to disable the port or start to brown out
[15:41] <shiftplusone> but the pi itself seems to be using about 0.2-0.3A while idle in X

[17:45] <ApatheticsAnonym> that seems like OTG to me
[17:45] <Habbie> it's not
[17:45] <Habbie> there is no uart in otg
[17:45] <Habbie> not a real one anyway
[17:46] <ApatheticsAnonym> hmm ok
[17:46] <Habbie> better find a howto tailored to pi zero

[17:46] <redrabbit> GrandPa-G: make yourself an iot coffee machine
[17:46] <ApatheticsAnonym> Would it be easier to host a wifi AP on the pi and connect via ssh?
[17:46] <Habbie> not easier, just different
[17:46] <GrandPa-G> redrabbit, i hate coffee
[17:46] <Habbie> connecting the pi yo your existing wifi is eaier
[17:46] <Habbie> easier
[17:46] <redrabbit> ok
[17:47] <ApatheticsAnonym> Im in a time crunch so anythign that requires special cables would be less than ideal
[17:47] * redrabbit hates bad coffee
[17:47] <ApatheticsAnonym> I wont have wifi as I'll be moving around
[17:47] <Habbie> then find a howto for otg serial with pi zero and mac
[17:47] <ApatheticsAnonym> hence my interest in OTG solutions
[17:47] <Habbie> and follow that
[17:47] <Habbie> note that your mac can also be an AP
[17:47] <Habbie> but either direction works, of course
[17:47] <Habbie> otg ethernet may be even better
[17:48] <Habbie> you can share your mac's internet to the pi over usb
[17:48] <redrabbit> anyone has used the rpi3 or 0W as a PAN gateway ?
[17:48] <Habbie> redrabbit, bluetooth?
[17:48] <gordonDrogon> distracted. brb.

[17:49] <redrabbit> could be a neater option than hostapd to get a shell on the go
[17:50] <Habbie> redrabbit, oh yes, good one
[17:50] <redrabbit> or even get internet connection on other devices with a low power footprint
[17:50] <Habbie> redrabbit, then it doesn't interfere with anything
[17:50] <gordonDrogon> GrandPa-G, I'm having fun with PDP-8 assembler.
[17:50] <Habbie> if i ever put a pi in my car i would probably give it internet via BT from the phone
[17:50] <BurtyB> otg ethernet and ssh can also be configured using just the boot partition (rather than serial which needs login enabling)
[17:50] <Habbie> as it draws a lot less power than wifi sharing
[17:50] <Habbie> BurtyB, indeed
[17:50] <redrabbit> well its still 2.4 ghz but it should interfere less since its lower power

[17:50] <gordonDrogon> Habbie, but in your car, both the Pi & phone can be powered...
[17:50] <Habbie> redrabbit, no i mean, if you run hostapd on the pi to connect your mac to, your mac cannot also have internet via wifi
[17:51] <Habbie> gordonDrogon, this is true, but then i'd need to figure out how to automatically enable the hotspot on the phone
[17:51] <Habbie> gordonDrogon, which i'm sure is doable
[17:51] <gordonDrogon> I regularly use my phone in hotspot mode to connect Pi 0W's to.
[17:51] <redrabbit> yep it also free up the wlan interface for other use
[17:51] <redrabbit> always good
[17:51] <Habbie> gordonDrogon, but also, with hotspot on -and- using the phone for satnav, power doesn't always keep up
[17:51] <gordonDrogon> Hm. not sure about automatic, but my phone lets me enable hotspot fairly easilly - swipe-down.
[17:51] <Habbie> to be fair that experience is with an ipad streaming netflix at 1.5gigabytes an hour from it
[17:52] <Habbie> gordonDrogon, yes, absolutely
[17:52] <redrabbit> gordonDrogon: tried the other way around ?
[17:52] <Habbie> redrabbit, what other way around?
[17:52] <gordonDrogon> redrabbit, what - the Pi as the hotspot?
[17:52] <redrabbit> using the phone as AP is quite fast and easy
[17:52] <redrabbit> yep
[17:52] <Habbie> i'm behind a pi3 hotspot right now, works well
[17:52] <Habbie> i'd imagine zero w to be no different
[17:52] <gordonDrogon> redrabbit, a remote Pi would have no internet connection in the first place.
[17:52] <redrabbit> as the BT Ap
[17:53] <redrabbit> to be precise
[17:53] <Habbie> oh BT
[17:53] <Habbie> i haven't
[17:53] <gordonDrogon> I sometimes connect multiple devices together - laptop, phone, and a pi0w or 3...
[17:53] <gordonDrogon> the phone is the common denominator as it were, so easy to just use hotspot on that.
[17:54] <gordonDrogon> wish I could better control its IP address and dhcp though.
[17:54] <redrabbit> there are guys selling a rpi3 based product (its all really a rpi3 with a nice case and preloaded software) that does that : BT Ap for android phones and stuff
[17:54] <Habbie> gordonDrogon, what do you miss in the ip/dhcp department?
[17:55] <gordonDrogon> having to run fping on my laptop to find the IP of a Pi 0.
[17:55] <Habbie> no mdns?
[17:55] <gordonDrogon> never looked.
[17:55] <Habbie> i just go ssh pi@raspberrypi.local

[17:57] <Habbie> gordonDrogon, now you have a reason to keep it
[17:57] <gordonDrogon> redrabbit, today it's 192.168.43.x
[17:57] <Habbie> gordonDrogon, alternatively, enable link local v6 on all machines and put the addresses in .ssh/config
[17:57] <redrabbit> ah its wifi hotspot and not BT ?
[17:57] <gordonDrogon> one day I'll make life easier for myself.

[19:01] <gordonDrogon> I did wheezy to strwtch recently.
[19:01] <gordonDrogon> no - wheezy to jessie.
[19:02] <gordonDrogon> I've updated many debians in the past - apt-get update/upgrade - edit /etc/apt/sources.list ; apt-get update ; apt-get update apt - then the apt-get dist-upgrade
[19:02] <gordonDrogon> there were some additionals on /etc/apt/sources.list.d for the Pi though.
[19:03] <gordonDrogon> My suspicions is that it might be quicker to re-install.
[19:05] <GrandPa-G> exactly why I am asking for experiences. I don't want to go where no man has gone before.

[19:08] <shiftplusone> use apt if you know know debian very well. Start from a clean image otherwise.
[19:08] <mfa298> my guess would be jessie-> stretch might be easier than wheezy->jessie as you're at least keeping the same init system

[20:08] <filadome> i plugged in my r.pi 3 and it's not showing anything on the screen
[20:08] <filadome> does it work with hdmi to DVI adapter?
[20:08] <filadome> the red light is on, is there an on button?
[20:09] * dreamon_ (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[20:15] <ali1234> it should do, but only DVI-D
[20:15] <ali1234> which not all DVI ports can necessarily do
[20:16] <ali1234> although it is unlikely you'd meet one like that
[20:16] <ali1234> there is no "on" button. just powering it up is enough
[20:16] <ali1234> you have to supply an SD card with operating system to make it work. it won't do anything at all without one
[20:16] <ShorTie> any sdcard in it ??
[20:17] <leftyfb> hey ali1234, question about your pistem. I'm pretty sure it's the case, but we should still be able to use the data usb port for a device when powered by your stem via usb-a correct? As long as we don't put it into gadget mode?
[20:17] <ali1234> yes
[20:17] <ali1234> or gadget mode
[20:18] <leftyfb> ok, cool. Gonna get my little bitcoin miners going again. It won't be much, but powered off of a solar panel, whatever I get it free money :)
[20:18] <ali1234> as long as the stem is only connected to a power pack, then the USB data port will work exactly like it normally does
[20:18] <leftyfb> hm
[20:18] <ali1234> oh boy... bitcoin mining on a pi... you will get precisely nothing
[20:19] <leftyfb> no
[20:19] <leftyfb> I have ASICs
[20:19] <ali1234> pennies then :)
[20:20] <ali1234> i guess what you need is a stem with a B plug on it
[20:20] <leftyfb> basically I have a 9 port usb hub (powered) that will power up 7 of the ASIC's, a fan and potentially the pi0w with the stem. The trick is, can I then plug in the usb cable from the hub into the data port on the pi which is technically plugged into one of the usb ports on the hub?
[20:20] <ali1234> a couple of people requested that before
[20:20] <ali1234> no, that won't work
[20:20] <filadome> i tried a HDMI to VGA as well
[20:20] <filadome> all that happens is the red light turnso n
[20:20] <leftyfb> looping the data port huh?
[20:21] <ali1234> you'd have to disconnect the data lines
[20:21] <leftyfb> ah
[20:21] <leftyfb> maybe I can find an adapter that removes the data lines
[20:21] * krautguy (~pi@x4db3b769.dyn.telefonica.de) Quit (Quit: Leaving)
[20:21] <ali1234> that would work, and they are widely available
[20:21] <filadome> will the screen turn on from low-power mode if i plug in the Pi without a boot device?
[20:21] <ali1234> but... what you really need is a B port. then you can just plug it directly into the hub upstream port
[20:22] <ali1234> like this https://images.monoprice.com/productlargeimages/3641.jpg
[20:22] <leftyfb> the pi would get power from that?
[20:22] <ali1234> according to the spec, no
[20:23] <ali1234> in practice, almost certainly yes
[20:23] <ali1234> you would also need to force usb host mode (override the OTG pin)

[20:24] <Latrina> guys I do have a question. Does the rpi3 needs some kind of proprietary usb uart connection in order to access its uart pins?
[20:25] <Latrina> whenever I screen on it I get stuck on black page
[20:25] <Latrina> and nothing, no sort of output comes up
[20:25] <ali1234> filadome: no. with no SD card it will do absolutely nothing except maybe flash a LED
[20:25] <Latrina> I am doing screen /dev/ttyUSB0 115200
[20:25] <ApatheticsAnonym> any thoughts on getting a "Gadget Serial v2.4: family specific matching fails" when attempting to connect an rpi0w to a mac w/ OTG (g_serial) configured?
[20:25] <filadome> ali1234, i don't want to use SD card, i want to use USB
[20:26] <ShorTie> you still need a sdcard to start with
[20:26] <ali1234> Latrina: you need to turn off serial getty before you can use the serial port
[20:26] <ShorTie> to be able to burn the usb bit
[20:26] <Latrina> ali1234: serial getty?
[20:26] <Latrina> I am not sure I understood it
[20:26] <filadome> ah, i followed the steps for SD card and used the USB in it's place
[20:27] <ali1234> Latrina: serial login prompt
[20:27] <Latrina> how do I do that?
[20:27] <Latrina> I am not using raspian though
[20:27] <ali1234> it will consume any data recived on the serial port before it gets to your screen
[20:27] <ali1234> you have to edit cmdline.txt and remove the part about "tty=/dev/ttyAMA0"
[20:27] <ali1234> also on pi3 you have to disable bluetooth with some device tree magic
[20:27] <Latrina> oh I will revise it but I guess I have done it already
[20:28] <Latrina> uhm
[20:28] <Latrina> yes I have no need for the bluetooth serial

[21:11] <shiftplusone> Either there's a hardware problem with your pi or your power supply and/or cable aren't up to the task
[21:13] <johndescs> you think it could be the cable? didn't try to change it, indeed…
[21:13] <ShorTie> temperature changes can cause Condensation
[21:14] <BCMM> ShorTie: was going to suggest that, but it really shouldn't happen for a temperature *drop*
[21:14] <BCMM> condensation when bringing it in from the cold would be possible
[21:14] <ShorTie> or when the sun hits the enclosure
[21:15] <ShorTie> thus heating it up
[21:15] <johndescs> thought the same :) but my last test case was testing inside, in front of the window, then putting it outside, waiting like 10 minutes and boom ^^

[21:17] <shiftplusone> aye, a good usb cable is rare and worth its weight in copper.
[21:17] <BCMM> ShorTie: to clarify, for condensation to occur the pi basically needs to be colder than the air around it
[21:17] <ShorTie> not rare to buy, but rare they come with chargers
[21:18] <johndescs> yep same cable in both cases, but you are right it's a random cable I found in a drawer… didn't think about cable at all
[21:18] <BCMM> being heated by the sun is similar to having just been brought outside, in that it is hotter than the surroundings
[21:18] <ShorTie> look for 1 that has 22awg on it

[21:20] <shiftplusone> rare to buy if you pick whatever is popular on ebay or amazon.
[21:20] <johndescs> didn't know about that awg unit, will check
[21:21] <shiftplusone> https://www.amazon.co.uk/gp/product/B00T0DW3M6
[21:21] <BCMM> if there is some very, very marginal power issue i suppose the reduced resistance resulting from lower temperature might trip something
[21:22] <Encrypt> Do you know guys whether a kind of "voltage stabilizer" exists for the Pi?
[21:22] * Gathis (~TheBlack@unaffiliated/gathis) has joined #raspberrypi
[21:22] <Encrypt> Something that would smooth the voltage with a kind of capacitor
[21:22] <shiftplusone> Encrypt: no, there's a fuse and a tvsd for the 5V line. And regulators for the 3v3 and lower lines.
[21:23] <BCMM> what is a "voltage stabilizer"? an external device you plug the pi in to help it work off dirty power?
[21:23] <shiftplusone> aye, there are caps of course.
[21:23] <GrandPa-G> johndescs, do you have any neighbors that have wifi? I find my pi sometimes connects via a restricted wifi and all kinds of problems ensue.
[21:23] <Encrypt> BCMM, Yeah
[21:23] <shiftplusone> oh... you mean an external device... my bad.
[21:24] <Encrypt> It seems that when I launch updates / installations of software the red light sometimes blinks
[21:24] <Encrypt> So adding like a small cap could help
[21:24] <shiftplusone> probably not
[21:24] <Encrypt> But I could simply buy another power supply
[21:24] <Encrypt> I've been using the same setup for years
[21:24] <BCMM> Encrypt: a small cap would help with, like, very transient needs for more power
[21:24] <shiftplusone> if your power supply is browning out or your cable has a high resistance, a cap can only help you so much.
[21:25] <BCMM> but when you install stuff the cpu needs more power for a period of time
[21:25] <Encrypt> Yeah

[21:25] <johndescs> GrandPa-G: I have up to like 50 APs in range… at least 50 SSIDs in iwlist :D but it's configured to connect immediately to my router only
[21:25] <Encrypt> And the writes happen on the SD Card, drawing powr
[21:25] <shiftplusone> note that the LED turns off not when the power is kind of lower than it should be, but when it's actually quite a lot lower than it should be...
[21:25] <BCMM> i thought you were talking about a power supply that generated it's own variations in voltage, like a battery pack - was gonna suggest a regulator
[21:26] <BCMM> but in this case voltage is dropping because you are drawing more current than the power supply can supply
[21:26] <Encrypt> shiftplusone, Right...
[21:26] * BOKALDO (~BOKALDO@46.109.201.17) Quit (Read error: Connection reset by peer)
[21:27] <shiftplusone> I just stick to the official power supplies from now on, since phone chargers are a gamble.
[21:27] <BCMM> it's reasonably common to have power supplies that advertise, like, 2A, 5V, but in reality, by the time you're drawing two whole amps, the voltage has dropped to like 4.5 or something

[21:27] <BCMM> and there's not a "stabiliser" to fix that - that's a genuine inability to provide the amount of power you need

[22:53] <mete> ah thanks
[22:53] <darsie> metawave: Ahh, you mean the 5 V 35 A PS? That's an ATX :).
[22:54] <darsie> mete*
[22:54] <ShorTie> you should not load a supply more then 70-80% of full capacity
[22:54] <mete> ah atx, ok then... :D

[22:54] <HrdwrBoB> ShorTie: because that's how shit works
[22:54] <mete> ah those tracos... I used one of them to power my PI, quet efficient those are ! but expensive too
[22:55] <ShorTie> you go for 100% then you get voltage drops most likely
[22:55] <darsie> Yeah, I originally suggested others, but the guy didn't order them and went to the conrad shop.
[22:55] <HrdwrBoB> and lose effeciency
[22:55] <mete> anyone here knows a step up regulator from 3V to 5V which can deliver ~20A?
[22:55] <ShorTie> lol.
[22:55] <HrdwrBoB> mete: if you need 20A you should rethink your design entirely
[22:56] <darsie> ShorTie: At 100% the voltage should be within spec.
[22:56] <darsie> mete: A boost converter should do.
[22:56] <ShorTie> it's the peaks and spikes that cause problems
[22:57] <HrdwrBoB> heh, my old server I had to change the disk startup to staggered
[22:57] <HrdwrBoB> it would RUN, but couldn't start

[23:00] <mete> HrdwrBoB: why? I don't know if I really need 20A... but, why not build something like that when you start at nearly zero? I have a battery in place which can deliver without problems 80-120A @3.2V continously...
[23:00] <HrdwrBoB> if your main load is 3.2V that makes sense
[23:01] <HrdwrBoB> but it's generally better to supply higher and regulate lower
[23:01] <ShorTie> cost alot more to build a 20a supply vs. 2a
[23:02] <mete> the battery is used mainly by a microcontroller which runs from it directly, without any step up/step down regulator. but I would also like to get a 5V supply from it..
[23:03] * ShorTie never heard of a 3.2v battery .. :/~
[23:03] <mete> i don't really have a idea for what I could use 20A or so... so I think I will then simply get a 2A step up to charge some USB devices...
[23:03] <mete> ShorTie: google for lifepo4
[23:04] <mete> long lifetime, high peak current. nice to run for example an esp8266 without any supply
