| 15:01 | <teknkik_> has anybody got any experience with running LTSP over an VPN
| |
| 15:01 | w/ separate computer for VPN connectivity; obviously it can technically work
| |
| 15:01 | <alkisg> Are you having any specific issues?
| |
| 15:01 | <teknkik_> nope
| |
| 15:01 | pondering about our setup in the future
| |
| 15:03 | anyway, the vpn would be over 100 megabit fiber optic connection and both ends in the same operators network
| |
| 15:04 | <alkisg> I'm not sure if DHCP can work over VPN, but other than that, you shouldn't have any issues...
| |
| 15:04 | gigabit is recommented for ltsp though
| |
| 15:04 | You could use fat clients with some local caching to speed it up
| |
| 15:05 | Or a proxy nbd server, to intercept the bulk of the traffic
| |
| 15:05 | (xnbd-server could do that part easily)
| |
| 15:07 | <teknkik_> well we use fat clients anyway; ltsp mostly provides an easy way of generating the disk images and hosting them
| |
| 15:08 | teknkik_ is now known as teknkik | |
| 15:08 | <alkisg> Are you using the default sshfs for home?
| |
| 15:08 | <teknkik> yep
| |
| 15:09 | sorry no, we use NFS directly from our file server
| |
| 15:09 | sshfs only for guest users
| |
| 15:09 | <alkisg> Which is over the vpn?
| |
| 15:09 | (the file server)
| |
| 15:09 | <teknkik> not yet
| |
| 15:09 | but in the future probably
| |
| 15:09 | <alkisg> And are you caching the squashfs image somewhere, or you only have that in the ltsp server?
| |
| 15:09 | (the one served via nbd)
| |
| 15:10 | <teknkik> on the server
| |
| 15:11 | we could actually just switch the guest users over to tempfs... it's not like the files are needed
| |
| 15:11 | would need to make an script to copy skel over to the new session every time a guest logs in
| |
| 15:11 | <alkisg> The file server will be in one location, right? So some of the users will be local, and the others remote?
| |
| 15:13 | <teknkik> yep, and the file server would be over the VPN after migrating
| |
| 15:14 | <alkisg> Instead of caching the nbd image, you could also mirror it in a second server
| |
| 15:16 | That server would have (proxy)dhcp, tftp and nbd services only
| |
| 15:19 | vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc) | |
| 15:19 | <teknkik> actually hm
| |
| 15:20 | we could just run the LTSP server locally although the home folders are on the external server
| |
| 15:20 | <alkisg> Sure
| |
| 16:07 | alkisg is now known as work_alkisg | |

| 16:46 | <Phantomas> vagrantc: work_alkisg told me that you found a bug when trying to broadcast with epoptes. Can you confirm that it's because a .config/epoptes directory wasn't created on the first run and that it worked the second time you tried after closing epoptes?
| |
| 16:52 | <vagrantc> Phantomas: i can try booting again...
| |
| 16:52 | Phantomas: or i could manually remove .config/epoptes and try again
| |
| 16:53 | Phantomas: i don't know if it matters ... i was also logging in from the console and running "startx" rather than using a display manager
| |
| 16:53 | <Phantomas> vagrantc: Sure, please run it from a terminal so we can see a traceback if something crashes.
| |
| 16:54 | I don't think that it matters.
| |
| 16:54 | khildin has left IRC (khildin!~khildin@ip-62-235-40-110.dial.scarlet.be, Ping timeout: 260 seconds) | |
| 16:56 | <vagrantc> Phantomas: it doesn't create ~/.config/epoptes at all
| |
| 16:57 | Phantomas: maybe some XDG_* variable isn't set, due to running without a display manager?
| |
| 16:59 | hrm. and now it created it on the third try...
| |
| 17:09 | !epoptes
| |
| 17:09 | <ltsp`> epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
| |
| 17:09 | * vagrantc forgets how to install the client certificates with ltsp | |
| 17:10 | <vagrantc> i guess i'll just do ltsp-pnp style instead.
| |
| 17:23 | Phantomas: ok, it appears to work once .config/epoptes gets created
| |
| 17:24 | although it didn't create .config/epoptes until the third launch
| |
| 17:24 | unless i'm confused
| |
| 17:25 | <Phantomas> back
| |
| 17:25 | vagrantc: It's a bug (epoptes bug). It creates the .config/epoptes dir whenever the config module wants to write a config file
| |
| 17:25 | and that, currently, happens when epoptes closes (clean close)
| |
| 17:26 | <vagrantc> after stopping epoptes, manually removing .config/epoptes, starting epoptes, broadcasts fail. stopping and then starting epoptes again makes it work
| |
| 17:26 | Phantomas: yup, you've got it.
| |
| 17:26 | i don't know if i was just confused about the third time issue
| |
| 17:26 | <Phantomas> yep. Thanks for the confirmation testing! Will fix it ASAP
| |
| 17:27 | <vagrantc> epoptes is stuck in jessie-backports NEW queue ... hopefully it'll get approved soon
| |
| 17:27 | <Phantomas> probably. Or you control-c'd it maybe?
| |
| 17:27 | <vagrantc> ah, that could be
| |
| 17:29 | <Phantomas> I'm not really familiar with the debian release processes (I feel a bit guilty :P). So didn't get much from what you said except that we'll get approved soon :D
| |
| 17:30 | <vagrantc> Phantomas: ah, current stable release is jessie, but i've uploaded the newer epoptes to jessie-backports, but it's still waiting on being approved to get into the archive
| |
| 17:31 | normally new upstream versions don't go into a debian stable release
| |
| 17:32 | <Phantomas> Oh, that's great, hope we get approved, we had quite a few fixes in 0.5.8
| |
| 17:32 | btw we are on 0.5 since 2012.... It's really time to move to 0.6
| |
| 17:33 | gvy has left IRC (gvy!~mike@altlinux/developer/mike, Quit: $HOME) | |
| 17:34 | <Phantomas> I think that 0.5 became a habit :p
| |
| 17:39 | <vagrantc> sure
| |
| 17:39 | in general, i'd increment at least once a year
| |
| 17:52 | <Phantomas> We do have time to do another epoptes release in testing before it becomes stable, right?
| |
| 17:52 | <vagrantc> plenty of time
| |
| 17:55 | Phantomas: roughly a year :)
| |
| 17:55 | <Phantomas> cool!
| |
| 17:57 | <vagrantc> or, at least till June

| 19:53 | <m3741> hey everyone, i'm running a headless ubuntu 14.04 x64 server to host ltsp, if that matters. why when i run ltsp-update-kernels does it set the permissions to not be world readable? my tftp server can't read vmlinuz etc then of course

| |
| 22:31 | <vagrantc> wheee
| |

| 22:36 | <sbalneav> heh
| |
| 22:39 | <maldridge> sbalneav: pushed to ubuntu?
| |
| 22:41 | Freejack has joined IRC (Freejack!~Freejack@unaffiliated/freejack) | |
| 22:46 | <sbalneav> maldridge: I doubt it.
| |
| 22:46 | Someone will have to package it.
| |
| 22:47 | <maldridge> I may be confusing things here, this is the thing that handles logins correct? I thought that was packaged
| |
| 22:48 | <sbalneav> There are two phases to software being available in a particular distro.
| |
| 22:48 | 1) is actually the "upstream" writing the software, fixing bugs, etc.
| |
| 22:48 | <maldridge> yes, but my understanding was the whole point of launchpad is that it does automatic package building
| |
| 22:49 | <sbalneav> No.
| |
| 22:49 | <maldridge> ah, that clears up my confusion
| |
| 22:49 | <sbalneav> They may automatically check it when it comes time to make another release.
| |
| 22:50 | But it won't get updated between releases.
| |
| 22:50 | In the meantime, you can just download the tarball, compile and install that way.
| |
| 22:50 | * maldridge is on another distro and shall package it there | |
| 22:51 | <maldridge> sbalneav: for a feature request, is there a place to route that to?
| |
