| 13:00 | <bennabiy_again> !seen alkisg
| |
| 13:00 | <ltsp`> alkisg was last seen in #ltsp 5 hours, 30 minutes, and 1 second ago: <alkisg> Hehe!!
| |
| 13:00 | <bennabiy_again> alkisg: you here?
| |
| 13:04 | <elias_a> bennabiy_again: alkisg lives in Greece. You might think about that when thinking when would be a good time to reach him.
| |
| 13:04 | <bennabiy_again> elias_a: I am aware of that, but also, I have found him in here at what appeared to be strange times :)
| |
| 13:05 | <elias_a> bennabiy_again: OK. Just thought I'd make sure that you know.
| |
| 13:05 | <bennabiy_again> Thank you.
| |
| 13:05 | elias_a: Do you have much experience with epoptes?
| |
| 13:06 | <elias_a> And LTSP is so strange that nothing is really strange after that.
| |
| 13:06 | <bennabiy_again> exactly
| |
| 13:06 | elias_a where are you from?
| |
| 13:07 | <elias_a> bennabiy_again: You mean the spying sw? Nope. I would never use it in school.
| |
| 13:07 | bennabiy_again: Finland
| |
| 13:07 | <bennabiy_again> spying sw?
| |
| 13:08 | <elias_a> bennabiy_again: Viewing a student's desktop without a written consent is a crime in Finland and AFAIK all EU countries.
| |
| 13:09 | bennabiy_again: Problem is - no one gets the written consents.
| |
| 13:09 | Thus using Epoptes is generally speaking a crime.
| |
| 13:10 | Next question, please! :D
| |
| 13:10 | <bennabiy_again> elias_a: students and teachers is not the only reason to use epoptes :)
| |
| 13:10 | What does 0x0 =?
| |
| 13:11 | by that I mean that it is not just for the school environment
| |
| 13:16 | <elias_a> bennabiy_again: Give me an example of legitimate use of Epoptes where the "must have written consent" -problem is not present.
| |
| 13:19 | <bennabiy_again> Well, since you asked. I maintain a computer lab for our group, which is not related to school at all, and there are times where I need to be able to remotely log someone onto a computer, or to help with an issue, help troubleshoot, etc.
| |
| 13:21 | The software is run on the lab that I maintain, on thin clients, and there is a mutual trust that the abilities of Epoptes would not be abused, but really, none of us are worried about it
| |
| 13:22 | Some people on the lab have dedicated user accounts, others use a general account based on the purpose that they need computer access.
| |
| 13:22 | And to sum it all up, none of us own "personal" computers, even if we have a computer dedicated to our personal use
| |
| 13:23 | So the issue is moot with us
| |
| 13:23 | Does that answer your question
| |
| 13:23 | ?
| |
| 13:24 | PhoenixSTF has left IRC (PhoenixSTF!~rudi@78.29.159.239, Quit: Leaving) | |
| 13:25 | <elias_a> bennabiy_again: Yes, but you are wrong.
| |
| 13:26 | bennabiy_again: As computers are typically used for personal communications as well you should have guidelines for the usage.
| |
| 13:28 | bennabiy_again: Or you might solve the problem by prohibiting all personal communication, including organizational or business communication that is not meant to be public.
| |
| 13:30 | <bennabiy_again> elias_a: Does not apply to us :)
| |
| 13:32 | We live a life of faith, and actually trust one another. I know it is a strange concept these days, but actually, it is possible to not have to be afraid of those around you being out to get you, or something
| |
| 13:33 | elias_a: and that is a strong statement to tell me that I am wrong.
| |
| 13:38 | <elias_a> bennabiy_again: Please tell me 1) what your activities are all about and 2) which country are we talking about?
| |
| 13:40 | <bennabiy_again> elias_a: what do you mean, what my activities are all about? I am in the US, but it would not matter what country I was in, in regards to our use of Epoptes
| |
| 13:45 | elias_a: I think I can truly say that you could not understand where I am coming from, so I know it probably fries your circuits to think that someone actually would not mind that there was the possibility that "someone" could be watching what I am typing right now... when that someone is someone who shares a common life with them, living together, working together, etc.
| |
| 13:46 | I will be back in a little bit, time to swap out a router
| |
| 13:52 | <elias_a> bennabiy_again: Just a brief comment: I do not want say anything about the legislative framework in US as the whole country is a moral and legislative disaster.

| 14:48 | <alkisg> elias_a: just wondering, why isn't LTSP (and all shared user systems) illegal then? The sysadmin can watch/do anything with the user accounts, epoptes doesn't have to be installed to do that...
| |
| 14:50 | <bennabiy_again> Hello alkisg!
| |
| 14:51 | <alkisg> Hi bennabiy_again
| |
| 14:52 | <bennabiy_again> alkisg: Is it possible to have a server also be a client in epoptes?
| |
| 14:52 | <alkisg> bennabiy_again: sure, you could, but I think if you describe your use case exactly, we'll find a better solution...
| |
| 14:54 | <bennabiy_again> I have different various computer labs, which would use it with a local administrator of the lab, and then a couple of us who would be overseers of the labs as a whole
| |
| 14:54 | <alkisg> What are you 2 using? ltsp fat clients? standalone PCs?
| |
| 14:54 | <bennabiy_again> Well, it is a mixed case
| |
| 14:54 | * alkisg is thinking of proposing x2go... | |
| 14:56 | <bennabiy_again> The labs are all thin clients, the controlling computer of the labs on a per lab basis would be the server, or one of the workstations on the lab (each lab is a 2 nic situation) and then the general overseer of all the labs would possibly be on a lab or standalone
| |
| 14:56 | And I would just be interested in the servers of each of the lab from that server
| |
| 14:57 | Also, one of my labs (the one I am currently setting up) the person maintaining the lab is not actually on the lab. Currently, he can see the clients, but not the server.
| |
| 14:58 | and since he is not on the thinclient subnet, he only sees the clients when a user is actually logged into the ltsp server
| |
| 15:02 | hmm, x2go might work for controlling the servers, and then epoptes from those servers to the local labs
| |

| 15:05 | <bennabiy_again> alkisg: Were you able to recreate your fix suggestion for mint?
| |
| 15:08 | alkisg: Even if you could sum up the thoughts you had on it, it would help me to know which direction to take it, as I have had a couple different thoughts on it.
| |
| 15:10 | <alkisg> bennabiy_again: yeah, the idea was to login with x2go on the servers, and then to be able to run epoptes from there
| |
| 15:10 | <bennabiy_again> That is basically what I was thinking. Thank you!
| |
| 15:10 | <alkisg> About the mint suggestion, sorry, I didn't have the time for it...
| |
| 15:11 | <bennabiy_again> I figured. I was stupid to not make the change right away
| |
| 15:11 | <alkisg> We (the schools support team) are very busy on the first few months of each school year...
| |
| 15:11 | Too many ltsp installations etc etgc
| |
| 15:11 | <bennabiy_again> Did school just start again?
| |
| 15:11 | we homeschool year round, so I lose track of time
| |
| 15:12 | alkisg: Do you ever get over to the states?
| |
| 15:14 | * alkisg went to an LTSP BTS and an Ubuntu UDS once, it was very nice... | |
| 15:17 | <bennabiy_again> For what it is worth, you have my personal invitation to any of our communities, if you are anywhere near them, and we will take care of you :)
| |
| 15:17 | You must come to one of our delis as well
| |
| 15:17 | my treat

| 15:41 | <other_other_joe> can someone give me some kiosk mode tips?
| |
| 15:42 | <bennabiy_again> !kiosk
| |
| 15:42 | <ltsp`> I do not know about 'kiosk', but I do know about these similar topics: 'kiosk-lucid'
| |
| 15:42 | <bennabiy_again> bah
| |
| 15:42 | <other_other_joe> I got a kiosk-esk situation going by enabling auto-login and auto-starting chromium in kiosk mode but I believe there is a more eligant way
| |
| 15:43 | yea, tried that already bennabiy :)
| |
| 15:43 | <bennabiy_again> what distro?
| |
| 15:43 | <other_other_joe> debian
| |
| 15:43 | <bennabiy_again> How are you auto starting chromium in kiosk mode?
| |
| 15:43 | do you have the users login shell set to chromium?
| |
| 15:44 | <other_other_joe> exec=chromium --kiosk $URL
| |
| 15:44 | nah
| |
| 15:44 | <bennabiy_again> why not?
| |
| 15:44 | Do you want the user doing other things?
| |
| 15:44 | <other_other_joe> I don't, no
| |
| 15:45 | I do want to be able to control it from epoptes and whatnot still though
| |
| 15:46 | Phantomas has joined IRC (Phantomas!~Phantomas@ubuntu/member/phantomas) | |
| 15:46 | <bennabiy_again> You probably could. Epoptes from what I understand operates on two levels, the user, and the system
| |
| 15:46 | <other_other_joe> I'm pretty sure there is a LDM_SESSION=kiosk type sitation
| |
| 15:46 | wherein you pass executables to the kiosk script
| |
| 15:46 | <bennabiy_again> probably
| |
| 15:47 | <other_other_joe> $CHROOT/usr/share/ltsp/screens.d/kiosk does exist
| |
| 15:47 | <bennabiy_again> that is a little too common sense for me...
| |
| 15:47 | I like making things hard
| |
| 15:47 | <other_other_joe> haha
| |
| 15:47 | yea
| |
| 15:47 | * bennabiy_again is a glutton for punishment! | |
| 15:47 | <other_other_joe> I've got it working the hard way now :D
| |
| 15:47 | very clumsy
| |
| 15:49 | --kiosk mode does remove the decoration from the browser and more or less makes it un-closeable
| |
| 16:06 | <bennabiy_again> that works, I guess
| |
| 16:07 | alkisg: x2go/epoptes is a good fit so far
| |
| 16:07 | thank you for the suggestion
| |
| 16:08 | for future reference, mate is not officially supported in the x2g0 sessions, so you just need to set /usr/bin/mate-session as the custom desktop session, and it works fine
| |
| 16:08 | x2go I mean
| |
| 16:09 | !LDM_SESSION
| |
| 16:09 | <ltsp`> Error: "LDM_SESSION" is not a valid command.
| |
| 16:09 | <bennabiy_again> !ldm
| |
| 16:09 | <ltsp`> ldm: LDM is the LTSP Display Manager, required for LTSP thin/fat clients, because it authenticates the users to the server via SSH.
| |
| 16:09 | <bennabiy_again> !x2go
| |
| 16:09 | <ltsp`> x2go: x2go is an NX-based suite of applications that allow logging in to a remote X server from any OS. It's much more efficient than VNC over slow network. More info: http://www.x2go.org/

| |
| 18:10 | <vagrantc> does it work fine when using it not as a thin client?
| |
| 18:11 | if so, then it's most likely just a bug in the driver for ubuntu

| 18:11 | <christophe_y2k> yes the server work fine, only whent i connect my fat client
| |
| 18:11 | <vagrantc> the server gets the error?
| |
| 18:12 | <christophe_y2k> oerror on server in #dmesg

| 18:13 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 18:13 | <vagrantc> christophe_y2k: test a different cable or switch, but most likely sounds like a bug in the driver...
| |
| 18:13 | christophe_y2k: i'd report it to ubuntu
| |
| 18:13 | <bennabiy_again> alkisg: was there something special to get 12.04 to work with x2go?
| |
| 18:13 | * alkisg waves | |
| 18:13 | <alkisg> bennabiy_again: no, just to connect with x2go before connecting via ssh to the server (old keys vs new keys)
| |
| 18:14 | <bennabiy_again> I am getting a message saying "The host key for this server was not found but an othertype of key exists.An attacker might change the default server key toconfuse your client into thinking the key does not exist"
| |
| 18:14 | <alkisg> Yeah, that's the one
| |
| 18:15 | You need to delete that key, ssh-keygen -R host etc etc
| |
| 18:15 | <christophe_y2k> another, my fat client are connected to an another ltsp server gentoo server (for users folder and router) --> ubuntu server (for dhcp pxe) -> fat client
| |
| 18:15 | <bennabiy_again> ahh, great
| |
| 18:16 | <other_other_joe> still hoping for some kiosk love
| |
| 18:16 | alkisg/vagrantc ?
| |
| 18:16 | <alkisg> other_other_joe: about kiosk? personally I've never used it...
| |
| 18:16 | <other_other_joe> ah, damn
| |
| 18:17 | well, there appears to be the workings of a kiosk solution
| |
| 18:17 | <vagrantc> SCREEN_07=kiosk
| |
| 18:17 | dunno if there's anything else you need
| |
| 18:17 | <other_other_joe> yea, I tried that
| |
| 18:17 | <vagrantc> needs to have a web browser and window manager installed locally
| |
| 18:17 | <other_other_joe> no go
| |
| 18:17 | oh yea?
| |
| 18:17 | hmm
| |
| 18:17 | imox has left IRC (imox!~imox@91-64-148-46-dynip.superkabel.de, Quit: imox) | |
| 18:18 | <vagrantc> there are also variables in /opt/ltsp/i386/usr/share/ltsp/screen.d/kiosk
| |
| 18:18 | KIOSK_*
| |
| 18:18 | <other_other_joe> from what I can infer based on the $CHROOT/usr/share/ltsp/screens.d/kiosk script, you can pass it exec's
| |
| 18:18 | yea
| |
| 18:18 | I couldn't seem to pass it anything it liked though
| |
| 18:18 | <vagrantc> did you install a browser in your chroot?
| |
| 18:18 | <other_other_joe> was hoping one of your guys were familiar with it
| |
| 18:19 | yep
| |
| 18:19 | <vagrantc> i rewrote it a bit to support debian a while back
| |
| 18:19 | <other_other_joe> I'm attempting to use the same chroot as my greater environment
| |
| 18:19 | * vagrantc should consider kiosks locally | |
| 18:19 | <vagrantc> hmmm...
| |
| 18:20 | <other_other_joe> I mean, I've got it working now sorta
| |
| 18:20 | just by starting chromium in kiosk mode
| |
| 18:20 | in .config/autostart/chromium.default
| |
| 18:20 | in .config/autostart/chromium.desktop rather
| |
| 18:20 | but it seems there is a more elagant solution
| |
| 18:22 | <vagrantc> don't have the time to test it now...
| |
| 18:22 | <alkisg> What would be fun:
| |
| 18:22 | mount an nbd swap space from the server,
| |
| 18:22 | format it as ext4 and mount it as /home/username
| |
| 18:23 | log in there, do all kiosk* customizations,
| |
| 18:23 | copy it to the server as a template,
| |
| 18:23 | and then the kiosk mode is just a local autologin, with that space remounted before login, so as to have it cleared on logout
| |
| 18:23 | <vagrantc> recent versions should autocreate the homedir on login
| |
| 18:23 | <bennabiy_again> I thought it would work if you just set a users login shell to chromium --kiosk
| |
| 18:25 | <other_other_joe> ah, I can futs with it later I suppose. It's more or less working the way I want
| |
| 18:26 | I do have a video weirdness I'd like to bounce off of someone though. Most of my boxes are nvidia but I've got a couple that are intel. Those I seem to need to force 1920x1080
| |
| 18:26 | [00:01:2E:4C:80:49] XRANDR_OUTPUT_01=VGA1 XRANDR_MODE_01=1920x1080
| |
| 18:26 | should work, no?
| |
| 18:27 | they definitely support xrandr an' all. I can xrandr --output VGA1 --mode 1920x1080 them manually
| |
| 18:27 | they don't seem to wanna take the instruction from my lts.conf however
| |
| 18:28 | * alkisg has seen a problem appearing recently with XRANDR_MODE_0 working fine on LDM, but after login the resolution was changed, possibly by some gnome component, but not by the usual ~/.config/monitors.xml... | |
| 18:29 | <alkisg> It appeared last month or so, in 12.04.3...
| |
| 18:29 | <other_other_joe> this is definitely not working in ldm either
| |
| 18:29 | <alkisg> Try getltscfg -a locally then
| |
| 18:30 | !screen_02
| |
| 18:30 | <ltsp`> screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
| |
| 18:30 | <vagrantc> nvidia mangles all sorts of libraries, if you're using the proprietary drivers
| |
| 18:30 | in ways often incompatible with other drivers
| |
| 18:30 | <other_other_joe> yea, I am using the proprietaries for nvidia
| |
| 18:31 | doesn't seem to be mangling the intel mod's though
| |
| 18:31 | as I can tell them to work manually
| |
| 18:31 | export XRANDR_OUTPUT_01
| |
| 18:31 | export XRANDR_MODE_01
| |
| 18:32 | they're there, alkisg
| |
| 18:32 | oh, maybe not
| |
| 18:32 | they appear to be unset but exported
| |
| 18:34 | ohh, it's setting the variable with the quotes in as a string
| |
| 18:34 | echo -e $"XRANDR_OUTPUT_01"
| |
| 18:34 | XRANDR_OUTPUT_01
| |
| 18:36 | that's whacky
| |
| 18:36 | you guys want me to file a bug on that?
| |
| 18:37 | <alkisg> other_other_joe: That echo command is wrong, is that yours, or from the ltsp code?
| |
| 18:37 | <other_other_joe> thats mine
| |
| 18:37 | <alkisg> echo "$XRANDR_OUTPUT_01"
| |
| 18:38 | <other_other_joe> right, that's what I mean
| |
| 18:38 | <alkisg> But pastebin'ing the output of getltscfg -a is better...
| |
| 18:38 | <other_other_joe> echo -e "$XRANDR_OUTPUT_01"
| |
| 18:38 | this produces nothing
| |
| 18:38 | <alkisg> It's supposed to do that.
| |
| 18:38 | Because you didn't source the output of getltscfg
| |
| 18:39 | Just pastebin the output for us to see it...
| |
| 18:39 | <other_other_joe> ah, ok
| |
| 18:39 | 1 sec
| |
| 18:40 | http://pastebin.com/raw.php?i=GLN9eypj
| |
| 18:42 | <alkisg> other_other_joe: XRANDR_MODE_0, not 01, single digit
| |
| 18:43 | Also don't use LDM_XSESSION but LDM_SESSION
| |
| 18:43 | <other_other_joe> oh, ok. I pulled the 01's straight from the pdf
| |
| 18:43 | I'll change it and give it a whirl
| |
| 18:44 | <alkisg> You can file a bug on that (the docs) ;)
| |
| 18:44 | <other_other_joe> :D
| |
| 18:44 | as for the XSESSION vs SESSION
| |
| 18:45 | Is XSESSION depreciate?
| |
| 18:45 | depreciated\
| |
| 18:45 | <alkisg> phone.. :)
| |
| 18:46 | <other_other_joe> ah cool. Thank you sir. I'll go bounce this thing and see if she works
| |
| 18:50 | <vagrantc> XSESSION is something people frequently and wrongly misuse
| |
| 18:50 | it's for a different purpose
| |
| 18:51 | it can leave you with broken sessions that fail in hard to troubleshoot ways
| |
| 18:51 | we should probably just disable it entirely, there are so many people using it due to bad documentation about unity/gnome3 bugs
| |
| 18:52 | "this random workaround fixed my problems, by tthe way, i'm not having all sorts of other issues..."
| |
| 18:52 | er ... "now having all sorts of other issues..."
| |
| 18:53 | <other_other_joe> haha
| |
| 18:53 | ok, I'll switch
| |
| 18:54 | could you give an example of when I'd want to use one vs the other?
| |
| 18:54 | <vagrantc> it was originally implemented because Ubuntu insisted in using /etc/gdm/Xsession instead of /etc/X11/Xsession, and other distros also had the corresponding file in other locations
| |
| 18:54 | <other_other_joe> single digit totally working btw alkisg
| |
| 18:54 | you are my sunshine
| |
| 18:55 | <vagrantc> other_other_joe: you would use LDM_XSESSION if you want a broken system, and LDM_SESSION when you want to change the default session :)
| |
| 18:55 | <other_other_joe> lol
| |
| 18:55 | fair enough :)
| |
| 18:56 | <vagrantc> i should send such an email to the ltsp-discuss list
| |
| 18:56 | the only use case you needed it for should be fixed by the use of ldminfod...
| |
| 18:57 | as the server tells you where to find it.
| |
| 18:57 | <other_other_joe> so should I pass LDM_SESSION the same "/usr/bin/startlxde" I'm using now or just lxsession maybe?
| |
| 18:57 | or just startlxde for that matter
| |
| 18:58 | don't know why I pathed it in the first place actually
| |
| 18:58 | <vagrantc> other_other_joe: the name of the .desktop file in /usr/share/xsessions/
| |
| 18:59 | i.e. LDM_SESSION=LXDE
| |
| 18:59 | hopefully you're not running a buggy version of ldm that started the whole mess...
| |
| 19:00 | <other_other_joe> If I recall I had trouble getting LDM_SESSION to work initially which is why I ended up here
| |
| 19:00 | it's been a while back and lots of script parsing ago though
| |
| 19:10 | that's right, I got ye ole "unable to launch Xsession LXDE...LXDE not found"
| |
| 19:11 | then it defaults to my default session. Which is LXDE actually, and starts fine
| |
| 19:15 | <vagrantc> sounds like buggy LDM version... take it up with your distro
| |
| 19:16 | other_other_joe: if it's your default session, just leave LDM_SESSION unset entirely
| |
| 19:17 | * alkisg has verified that XRANDR_MODE_0 no longer works properly | |
| 19:17 | <alkisg> It works on LDM, but after login, the highest resolution is applied instead...
| |
| 19:20 | <other_other_joe> yea, when I set it I was trying out several
| |
| 19:21 | <alkisg> After manually running gnome-session (fallback) from xterm, I got === xinerama setup Configuration ===, /me googles about that...
| |
| 19:22 | <other_other_joe> xinerama is the old X multi-display setup
| |
| 19:26 | <alkisg> gnome-settings-daemon => ./plugins/xrandr/gsd-xrandr-manager.c
| |
| 19:27 | Probably a regression caused by https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1065979

| 20:02 | <bennabiy_again> alkisg: If I have thin clients currently defaulting to cinnamon, but want to switch them to mate, would the change just need to be on the server end, or do I need to change something in the chroot as well?
| |
| 20:06 | <other_other_joe> we were just discussing that actually
| |
| 20:07 | <bcdonadio> My thinclient seems not to be getting the LOGSVR and ROOTPATH variables from the dhcp server, but only those two. All other parameters are correctly being read. As a result of this, the thinclient isn't able to mount the NBD image. What could be going wrong?
| |
| 20:07 | <other_other_joe> LDM_SESSION=mate in your lts.conf

| 20:30 | <other_other_joe> I know there is a distro specific flag to the ltsp-build-client
| |
| 20:30 | lemme see if I can dig it up
| |
| 20:31 | <bennabiy_again> ageis: might be touch and go. You could always generate a 10.04 image by setting --dist
| |
| 20:31 | 10.04 = LTS right?
| |
| 20:32 | <ageis> indeed
| |
| 20:32 | thanks
| |
| 20:32 | <bennabiy_again> sudo ltsp-build-client --dist=lucid
| |
| 20:32 | Is there a reason you want to use a 12.04 image?
| |
| 20:33 | <ageis> the server and client image is both 10.04 right now, I'm jsut wondering what would happen if I were to chroot into the image and do a dist-upgrade.
| |
| 20:33 | <bennabiy_again> What would you gain from it?
| |
| 20:34 | <other_other_joe> ltsp-build-client --dist $CODENAME
| |
| 20:34 | <ageis> contemplating software upgrade for client with large deployment
| |
| 20:34 | otehr_other_joe: does that take a destination argument? so I could test it but keep the old one
| |
| 20:35 | <other_other_joe> sure
| |
| 20:35 | check out ltsp-build-client --extra-help
| |
| 20:35 | lots of niftyness
| |
| 20:35 | <ageis> will do, thanks
| |
| 20:35 | <other_other_joe> np
| |
| 20:39 | <ageis> what does ltsp-update-image do?
| |
| 20:40 | <other_other_joe> that creates an nbd image
| |
| 20:40 | based on your chroot
| |
| 20:40 | compresses the chroot with squashfs
| |
| 20:41 | then the clients can mount the image as a network block device rather than exporting the chroot via nfs
| |
| 20:41 | <ageis> gotcha, what's the default path for nbd images? I'm not sure whether it's using that or not
| |
| 20:42 | <other_other_joe> ubuntu defaults to nbd I believe
| |
| 20:42 | /opt/ltsp/$arch/images
| |
| 20:43 | <alkisg> ageis: don't dist-upgrade chroots, re-create them
| |
| 20:43 | Also, nbd-server configuration is incompatible between 10.04 and 12.04
| |
| 20:44 | The first is port-based, the second is name-based
| |
| 20:44 | So you'd also need some manual configuration editing to make it work
| |
| 20:45 | <ageis> understood
| |
| 20:46 | <other_other_joe> /srv/tftp/ltsp/amd64/pxelinux.cfg/default will tell you which you're using
| |
| 20:46 | if you didn't know up until now though, it's likely nbd
| |
| 20:47 | <ageis> yeah, there's an image in /opt/ltsp/images. but I was chrooting into /opt/ltsp/i386 -- I guess any changes I made would not have got included until I run update-image, huh
| |
| 20:47 | <other_other_joe> correct
| |
| 20:48 | <ageis> cool. learning this from scratch, but learning fast
| |
| 20:48 | <other_other_joe> ltsp-update-image will also backup your existing image
| |
| 20:48 | <ageis> I don't see an argument to specify output image filename
| |
| 20:48 | <other_other_joe> so ./images/ should have current and .old
| |
| 20:48 | <ageis> ah
| |
| 20:49 | brunolambert has joined IRC (brunolambert!brunolambe@nat/revolutionlinux/x-qztffmluzxcadxhp) | |
| 20:49 | <other_other_joe> but if you've got a lot riding on it, no harm in copying that image somewhere else the first time
| |
| 20:49 | just to make sure I'm right :)
| |
| 20:50 | <bennabiy_again> other_other_joe: true :) that is good advice
| |
| 20:50 | <ageis> will it be unavailable for boot to the clients while updating?
| |
| 20:52 | <other_other_joe> I'm not sure actually
| |
| 20:52 | I find that it disrupts my users
| |
| 20:52 | it does move the file thats being served up so, it makes sense that it would choke them
| |
| 20:52 | I don't run NBD
| |
| 20:52 | <ageis> k
| |
| 20:52 | <other_other_joe> but when I am, I have to update that image after hours
| |
| 20:53 | <alkisg> ageis: no it doesn't disrupt them, it uses a temp file and it moves it in place when it's ready
| |
| 20:53 | <bennabiy_again> that is what I thought
| |
| 20:53 | only if you make a new image does it disrupt them
| |
| 20:53 | when it restarts nbd
| |
| 20:54 | <alkisg> ltsp-update-image doesn't restart nbd
| |
| 20:54 | <bennabiy_again> it says ...might be hard on clients... REBOOT!.. or something like that
| |
| 20:54 | no no no... ltsp-build-client
| |
| 20:54 | <ageis> oh great. where else can I look for the tftp/nbd config files?
| |
| 20:54 | <alkisg> tftp in /var/lib/tftpboot/ltsp/i386/
| |
| 20:54 | nbd in /etc/nbd-server
| |
| 20:54 | for 10.04, in /etc/inetd.conf
| |
| 20:55 | <ageis> perfect!
| |
| 20:56 | looks like kernels are in the tftp root, I can update or install those with ltsp-update-kernels?
| |
| 20:59 | so this line in inetd.conf is actually specifying the location of the nbd image to serve up 2000 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/i386.img

| |
| 20:59 | give this guy a read
| |
| 20:59 | <ageis> ty
| |
| 20:59 | <other_other_joe> it's a bit dated
| |
| 21:00 | but there is some good stuff in there as far as utils and variables to set
| |
| 21:00 | writing custom ldm scripts and what not
| |
| 21:00 | good things
| |
| 21:01 | PhoenixSTF has joined IRC (PhoenixSTF!~rudi@78.29.159.239) | |
| 21:02 | <bennabiy_again> For his version, it is not so dated
| |
| 21:03 | <other_other_joe> oh right, lol
| |
| 21:03 | <vagrantc> "apt-get install ltsp-docs" for an only slightly outdated version
| |
| 21:03 | YMMV

| 21:22 | <ageis> what's the size variable in nbdswapd.conf for?
| |
| 21:25 | <other_other_joe> more swap
| |
| 21:25 | default's pretty small
| |
| 21:27 | Network Swap section in that manual covers it pretty well
| |
| 21:27 | <ageis> great
| |
| 21:28 | ok, I'm having issues w update image command, it seems to freeze somehwere in /proc where its like Failed to read file.. creating empty file
| |
| 21:29 | <other_other_joe> ./proc should be empty
| |
| 21:30 | <ageis> aha, they got put there by the mount operations of my chroot
| |
| 21:30 | <other_other_joe> gotta unbind that stuff
| |
| 21:31 | proc dev and sys
| |
| 21:32 | <ageis> proc and sys successfully unmounted, /opt/ltsp/i386/dev device is busy and can't find the process w/ lsof =/
| |
| 21:33 | <other_other_joe> that stuff gets wonky
| |
| 21:33 | <ageis> oh I got it
| |
| 21:33 | had to umount pts first
| |
| 21:33 | <bcdonadio> Got the thinclient to boot, now it's unable to load the LDM screen if server A is being choosen by the load balancer, but does load correctly at server B. What should I look for in server A?
| |
| 21:34 | <other_other_joe> i'd point the balancer exclusively to A
| |
| 21:34 | boot and start tail'ing logs
| |
| 21:35 | seems like your files are out of sync though
| |
| 21:36 | <bcdonadio> other_other_joe, yup, I'm just not sure what log should I look at. The syslog from the thinclient is just repeating the wget'ing of the configurations from the ltsp-cluster-control.
| |
| 21:37 | <other_other_joe> /srv/tftp/ltsp/* /var/lib/tftpboot/ltsp/* all checksum the same?
| |
| 21:39 | <bcdonadio> other_other_joe, there's no /srv/tftp in any of those servers, server A is tftp+root+appserv with saucy, server B is just appserv with precise (for testing)
