I have a big problem... can I ask here something?

<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

See these links for more info:

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

<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

15:49telex 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

<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

<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. :-)
17:24work_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...

<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>
:-)

<maldridge>
how is mate vs cinnamon?

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
18:04uXus has left IRC (uXus!~uXus@217.77.222.72, Quit: ail bi bek)
18:05
<alkisg>
Yes half the thick clients have issues with 3d

<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
