| 09:21 | <Guest76152> I have a big problem... can I ask here something?
| |
| 09:27 | ...about ltsp on raspberry...
| |
| 09:35 | <Hyperbyte> !ask
| |
| 09:35 | <ltsp> ask: Don't ask to ask a question, simply ask it, and if someone knows the answer, they'll respond. Please hang around for at least a full hour after asking a question, as not everybody constantly monitors the channel.

| 09:39 | <Guest76152> how can I create a LTSP between a Ubuntu server and three Raspberry Pi 2, that seems not to have pxe or etherboot possibilities?
| |
| 10:11 | <Hyperbyte> See these links for more info:
| |
| 10:11 | !raspberrypi
| |
| 10:11 | <ltsp> raspberrypi: (#1) LTSP with raspberry pi: http://cascadia.debian.net/trenza/Documentation/raspberrypi-ltsp-howto/, or (#2) To use a similar environment to LTSP on the raspberry pi http://berryterminal.com/, or (#3) https://github.com/gbaman/RaspberryPi-LTSP, or (#4) https://pi-ltsp.net
| |
| 10:11 | <ogra_> you could set up an SD card with uboot
| |
| 10:35 | <Guest76152> thanks! I'll try them

| 15:31 | <championofcyrodi> how do i use a separate server for sshfs home folder?
| |
| 15:31 | e.g. nbd running on the tftp server, but when users log in, home folder is mounted elsewhere

| 15:49 | telex has left IRC (telex!teletype@freeshell.de, Remote host closed the connection) | |
| 15:49 | <work_alkisg> the sshfs server is the ldm server
| |
| 15:49 | LDM_SERVER=xxx in lts.conf
| |
| 15:49 | I.e. authentication for both login and /home is one and the same
| |
| 15:50 | telex has joined IRC (telex!teletype@freeshell.de) | |
| 15:50 | <work_alkisg> championofcyrodi: ^
| |
| 15:59 | <championofcyrodi> hmmm
| |
| 16:00 | is authentication provided via 'sshfs' ? the device i want to use is a 'synology' which has 20Gbps and supports sshfs
| |
| 16:00 | but if i just 'ssh' it does not work
| |
| 16:01 | work_alkisg: one of these: https://www.synology.com/en-us/products/DS1815+
| |
| 16:03 | oh wait... its this one: https://www.synology.com/en-us/products/DS2015xs
| |
| 16:03 | with the dual SFP+ ports for the dual 10GBps
| |
| 16:03 | Gbps*
| |
| 16:30 | <vagrantc> it uses ssh for authentication
| |
| 16:30 | sshfs is mounted through the ssh master socket

| 17:08 | <work_alkisg> 10 Gbps?! Wow...
| |
| 17:14 | <Hyperbyte> work_alkisg, welcome in 2015! :-)
| |
| 17:14 | I found myself recently reminiscing back to the time when floppies were 320 kilobit and you needed to keep your programming small enough so it'd fit.
| |
| 17:15 | Now you send 32768 floppy disks per second. :-)
| |
| 17:24 | work_alkisg is now known as alkisg | |
| 17:25 | * alkisg used to write programs like tetris in assembly just to save size... under 1Kb, i.e. just 2 floppy disk sectors :) | |
| 17:26 | <alkisg> 10 gbps is really good, but e.g. 15 fat clients with local SSD disks get 10 times more than that...
| |
| 17:27 | Hyperbyte: did you try that mate 15.xx?
| |
| 17:27 | I think I'll work on that overlayfs issue...

| 17:42 | <championofcyrodi> security requirements disallow usage of anything with persistent storage in our environment.
| |
| 17:43 | let me rephrase. in the room with the clients.
| |
| 17:43 | <alkisg> Sure
| |
| 17:43 | <championofcyrodi> the servers of course have persistent disks. but are not in the same space.
| |
| 17:43 | <alkisg> It's good to support various options, people will always need different things
| |
| 17:43 | <Hyperbyte> alkisg, I haven't done it yet.
| |
| 17:43 | <championofcyrodi> so no USB, SSD, Magnetic, etc.
| |
| 17:43 | <alkisg> But the defaults can utilize whatever's there...
| |
| 17:44 | <championofcyrodi> so we stuff the fat clients w/ 16GB RAM and Core i3
| |
| 17:44 | <alkisg> Hyperbyte: np, I've just installed 15.10 and saw the issue
| |
| 17:44 | <Hyperbyte> alkisg, we're getting fibre at work, which is awesome. To make it extra awesome from a user experience standpoint, I thought I'd upgrade my terminal server with 12.04 gnome fallback to 15.04 mate.
| |
| 17:44 | <alkisg> Hyperbyte: I'd suggest 14.04 mate
| |
| 17:44 | <Hyperbyte> alkisg, but... turns out the server was already running 14.04.. I completely forgot I upgraded it.
| |
| 17:44 | <alkisg> They update it via their ppa
| |
| 17:44 | So it's quite recent
| |
| 17:44 | Ah, just install mate then :)
| |
| 17:45 | <Hyperbyte> Since going from 14.04 to 15.04 isn't really good idea... and Gnome fallback is already very close to mate....
| |
| 17:45 | <alkisg> Or leave it to flashback :D
| |
| 17:45 | <Hyperbyte> I figured I'd leave it for now.
| |
| 17:45 | <alkisg> Cool
| |
| 17:45 | <Hyperbyte> :-)
| |
| 17:52 | <maldridge> how is mate vs cinnamon?

| 17:57 | <alkisg> maldridge: mate works in clients that don't have 3d acceleration, that's its main importance
| |
| 17:58 | unity, gnome-shell, cinnamon require 3d, so they don't work in half the clients...
| |
| 17:59 | <maldridge> hm, I'm running thick installs, so that isn't as much of a concern. Cinnamon does this foolish preloading where it tries to su over to literally every user while at the greeter, I've heard Mate is similar but lighter

| 18:25 | <alkisg> Haha a friend of mine was on vacations, tried to upgrade to windows 10 and got left with a "grub rescue>" prompt
| |
| 18:25 | And he didn't have a usb stick or live cd with him
| |
| 18:25 | ...after a lot of searching... he used drivedroid to emulate a cdrom with his phone,
| |
| 18:25 | then he connected to me with reverse vnc,
| |
| 18:26 | i fixed his boot manager with dd mbr etc, and then I tested it if it was working with kvm
| |
| 18:26 | ...so from now on we'll only be taking our phones with us, no usb sticks or anything else :D
| |
| 18:26 | <Hyperbyte> :-D
| |
| 18:29 | That is actually quite awesome!
| |
| 18:29 | <alkisg> And we was talking to me through the phone that was emulating the live cd... pretty funny
