| 01:18 | <Stefn> Hello, I have set up an LTSP network which works. Most of my computers are running, but when I log in to one computer I only get my background image, and my nfs-folders
| |
| 01:18 | but the application, system, clock don't appear
| |
| 01:19 | does anyone know what the problem could be?

| |
| 03:24 | =D
| |
| 03:25 | <alkisg> Hehe
| |
| 03:26 | * alkisg tries to minimize his irc-online hours actually due to his phd | |
| 03:28 | <Hyperbyte> You're trying to get your PhD? :)
| |
| 03:29 | <alkisg> Yup, in the 2nd year currently
| |
| 03:29 | <Hyperbyte> Cool. :) PhD in what?
| |
| 03:29 | <alkisg> Teaching of informatics
| |
| 03:29 | <Hyperbyte> :D
| |
| 03:30 | How many years does it take?
| |
| 03:30 | <alkisg> I hope 3 (I had already done some work before)
| |
| 03:32 | <Trixboxer> which university alkisg ?
| |
| 03:32 | <alkisg> Here in Greece
| |
| 03:32 | (Patras)
| |
| 03:32 | <Hyperbyte> Dr. A. Georgopoulos. Suits you. :)
| |
| 03:32 | <alkisg> Haha nope won't use that, ever
| |
| 03:33 | <Hyperbyte> Hah, are you kidding me?!
| |
| 03:33 | <Trixboxer> hmm no idea abou greece.. hows research going there ?
| |
| 03:33 | <Hyperbyte> I'd make all my students call me dr.!
| |
| 03:37 | <Stefn> alkisg, edubuntu 10.04
| |
| 03:37 | <alkisg> Stefn: how are you using nfs?
| |
| 03:38 | <Stefn> I mount my folders on boot on my ltsp server
| |
| 03:39 | but it makes no sense, when I attach that computer on another network cable it runs fine, but any other pc will boot on that other place too, and I need the components from the pc that ain't working on that place
| |
| 03:43 | <alkisg> Ah, so it sounds like a cabling problem then?
| |
| 03:45 | <Stefn> thought about that too, but another computer can boot, and shows everything from that cable... so it's really weird
| |
| 03:51 | <Hyperbyte> Stefn, what does "another network cable" mean? Does it mean another cable, plugged into a different endpoint, possibly ending up at another routing, another DHCP server, etc...?
| |
| 03:52 | Or does it mean you just exchanged one network cable for another?
| |
| 03:53 | <Stefn> Another cable from the same switch
| |
| 03:54 | <Hyperbyte> Okay, so debug further.
| |
| 03:55 | Problem lies in either cable, switch or switch settings if one works and the other doesn't...
| |
| 03:56 | <Stefn> I now booted with only the basic devices and now it works... so I'll guess I'll find it soon now
| |
| 03:56 | thanks for the help :)
| |
| 03:56 | <alkisg> Stefn: some nics are better than the others
| |
| 03:56 | shawnp0wers (~spowers@linuxjournal/staff/shawnp0wers) joined #ltsp. | |
| 03:56 | <alkisg> So e.g. an intel NIC might work OK with a specific cable while a realtek might have problems with it
| |
| 03:56 | If your client works OK with another cable, then it's a cabling problem
| |
| 03:57 | shawnp0wers (~spowers@linuxjournal/staff/shawnp0wers) left irc: Client Quit | |
| 03:57 | <alkisg> *unless* it's random, and you've been hit by the nbd-proxy problem
| |
| 03:57 | (in case it randomly "happened" to work when you switched the cable)

| 06:27 | <gothaggis> i'm having some trouble with printing. I've installed cups on teh server and cups cups-client cups-bsd in the chroot for the thin clients. i'm running firefox as localapp - i run firefox-svr on the server and have added the printers. if i try to print from firefox using the server version, the printers show up..but the printers don't show up in the clients. did i miss a step?

| 08:01 | <veloutin> are you using ps3's as ltsp clients? :P
| |
| 08:01 | with their whopping 256MB ram?
| |
| 08:01 | <muppis> veloutin, nope, that's why it's offtopic.
| |
| 08:01 | <mgariepy> hello, anybody have a problem if i push a rewrite of nbd-proxy in ltsp-trunk ?
| |
| 08:02 | <veloutin> mgariepy: I don't
| |
| 08:02 | but I'm biaised
| |
| 08:02 | <mgariepy> veloutin, ok thanks :P
| |
| 08:02 | <veloutin> biased*
| |
| 08:06 | <muppis> veloutin, and 256 is enough. I have one client wiwth that amount of memory and CPU is Celeron 800MHz.
| |
| 08:07 | <robehend11> I've got a few with that much as well.
| |
| 08:07 | but all they do now is digital signage, so its nothing special
| |
| 08:07 | <veloutin> as long as you don't run any localapps like firefox ^^
| |
| 08:08 | <muppis> veloutin, well, that's true.
| |
| 08:08 | Firefox itself runs fine, but Flash is the killer.
| |
| 08:08 | <veloutin> but yeah it's a question of having the hardware that corresponds to the needs anyways, 256MB is enough for some needs
| |
| 08:12 | <abeehc> the possible refund make a lot of sense to me
| |
| 08:16 | <veloutin> some sense...
| |
| 08:17 | you can still install OtherOS with old firmware, you just don't get to play along in PSN too
| |
| 08:17 | IIRC
| |
| 08:17 | <abeehc> yeah that's what i understand sorta to... though I don't think the downgrade is trivial if possible (and, i guess it's illegal on my continent)
| |
| 08:22 | <muppis> Whole point was there that you can't use PSN and watch newest BD -movies with downgraded fw.
| |
| 08:22 | <abeehc> i was gonna say, skipping the upgrades impacts bd playing from what i heard too
| |
| 08:23 | <muppis> Which makes it impossible to keep Other OS support and use it for playing/watching.
| |
| 08:24 | Shame CDB publishes their decisions only in finnish.

| |
| 09:40 | <abeehc> HI
| |
| 09:41 | brunolambert (~brunolamb@2001:470:8829:1000:221:6aff:fe94:21d8) left irc: Ping timeout: 264 seconds | |
| 09:42 | <Mip5> What's the preferred way to set auto shutdown on thin clients? I've edited my lts.conf file to include (no quotes): SHUTDOWN_TIME = "14:00:00" and another line: TIMESERVER = IP address of my server.
| |
| 09:42 | It looks like not all of my machines shutdown, though I wasn't in the lab, so don't know whether some were still logged in or not. Is there a better way to make this happen?
| |
| 09:43 | <abeehc> I can't say i've tried that directive
| |
| 09:43 | <alkisg> I think the machines get a prompt on shutdown, which is canceable by the users
| |
| 09:44 | So maybe on those terminals the users did press cancel
| |
| 09:44 | <Roasted_> If the user is logged in, they won't get a prompt. They simply won't shut down.
| |
| 09:44 | Once they log out, they shut down within 10 seconds via prompt.
| |
| 09:45 | mistik1 (mistik1@unaffiliated/mistik1) left irc: Read error: Connection reset by peer | |
| 09:45 | <Mip5> Roasted: If they log out, but don't answer the prompt, does that mean they won't shutdown?
| |
| 09:45 | <Roasted_> If they log out, it'll say system will halt in 10 seconds.
| |
| 09:45 | If they do not hit cancel, it'll power off.
| |
| 09:46 | mistik1 (mistik1@unaffiliated/mistik1) joined #ltsp. | |
| 09:46 | <Roasted_> Make sure your time stamps match up at the login screen. I had severe issues with my time meshing up, which resulted in completely wacked out shutdown times.
| |
| 09:46 | In fact, the following day I would boot up 2 systems in particular and they would auto halt right away, even though ti was the next morning.
| |
| 09:46 | <Mip5> Okay - I'll check that.
| |
| 09:46 | BrechtM (c1beb337@gateway/web/freenode/ip.193.190.179.55) joined #ltsp. | |
| 09:46 | <Roasted_> I ended up not utilizing this feature as there are still issues I am having in the time department. But that's something to be aware of.
| |
| 09:46 | Also note, I had different time stamps when logged in vs at login screen.
| |
| 09:46 | Logged in yields the server time, which is likely to be correct. The time stamp at the login screens are different.
| |
| 09:47 | I would advise you work with the lab after hours when nobody is there. Boot all systems up and see what the time stamps are. See if they all match 100% or if they are all over the place.
| |
| 09:47 | Then edit your lts.conf to shut the systems down 10-15 minutes from the current time. Go get a cup of coffee and when you come back see if they powered off on their own.
| |
| 09:47 | <alkisg> Roasted_: you're still having time sync problems?!
| |
| 09:47 | <Roasted_> alkisg, Not after you helped me.
| |
| 09:47 | <alkisg> ok
| |
| 09:47 | <Mip5> Okay - I'll do that.
| |
| 09:48 | <Roasted_> alkisg, but you made it sound like that was just a quick patch and it was a work in progress to get fixed.
| |
| 09:48 | <alkisg> Nope
| |
| 09:48 | <Roasted_> alkisg, "fixed" as in an official "included in the entire package" type thing.
| |
| 09:48 | BrechtM_ (c1beb337@gateway/web/freenode/ip.193.190.179.55) joined #ltsp. | |
| 09:48 | <Roasted_> Will what you suggested be included in, say, the next version of ltsp?
| |
| 09:48 | <alkisg> The fix was just fine, I was just trying to see if that problem could possibly affect other LTSP areas
| |
| 09:48 | <Mip5> I think that many of my students just leave, and don't log out. Is there way to auto logout, and then autoshutdown?
| |
| 09:48 | <alkisg> Roasted_: the bug report I filed *wasn't* in LTSP, but in upstart
| |
| 09:49 | Totally different package
| |
| 09:49 | <BrechtM_> I'm having trouble with the resolution stuck at 800x600 when my ltsp client is connected to a monitor over a vga switch
| |
| 09:49 | <Roasted_> Mip5, I have not tinkered with any logout features, nor do I recall seeing it as an available entry.
| |
| 09:49 | <BrechtM_> any ideas?
| |
| 09:49 | <Roasted_> alkisg, so the problem I was experiencing wasn't LTSP related?
| |
| 09:49 | <alkisg> Roasted_: yes. Vagrantc put a workaround in ltsp, which works fine, but the problem didn't originate from ltsp.
| |
| 09:50 | BrechtM_: does it work OK without the switch?
| |
| 09:50 | <Roasted_> alkisg, I see. So your bug was with a different package which caused the issue. But vagrantc posted the fix to work around the issue.
| |
| 09:50 | <alkisg> Roasted_: yes
| |
| 09:50 | <Roasted_> alkisg, my question is if some other user out there in the world installs edubuntu and ltsp just like I did, will they automatically have vagrantc's fix included in it?

| |
| 09:51 | <Roasted_> was it too late for 11.04?
| |
| 09:51 | <alkisg> Maybe in natty, maybe later on
| |
| 09:51 | <Roasted_> ah good deal
| |
| 09:51 | <alkisg> http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/changes
| |
| 09:51 | <Roasted_> is there a ltsp 6 on the horizon?
| |
| 09:51 | <BrechtM_> I tried using DISABLE_XRANDR in lts.conf
| |
| 09:51 | <Roasted_> 1816 - nice
| |
| 09:51 | <BrechtM_> but that didn't seem to make any difference
| |
| 09:51 | <alkisg> Commit 1816 => I think it will be there in Natty
| |
| 09:51 | <Roasted_> alkisg, you and your buddies here really need to stop being so awesome.
| |
| 09:51 | <alkisg> | |
| 09:52 | <BrechtM_> yes in that case it detects the monitor just fine
| |
| 09:52 | I see it in the Xorg log
| |
| 09:53 | with the switcher, the xorg log reads "VESA VBE DCC read failed"
| |
| 09:53 | and it defaults to 800x600
| |
| 09:53 | with seemingly no way to force it higher
| |
| 09:54 | <alkisg> BrechtM_: when it works OK, what resolution does it get? 1024x768@85Hz?
| |
| 09:54 | <BrechtM_> it gets the resolution I set in lts.conf, which is in most cases 1280x1024
| |
| 09:54 | don't know the refresh rate
| |
| 09:54 | <alkisg> BrechtM_: ok, reboot it without the switch, write "xrandr" and post the results to pastebin
| |
| 09:54 | <BrechtM_> I set the resolution using X_MODE_0
| |
| 09:55 | <alkisg> Don't set the resolution with X_MODE_0 when you do that
| |
| 09:55 | If you have to, set it with XRANDR_MODE_0
| |
| 09:56 | <BrechtM_> I'm using ltsp to run a citrix ica client on display 2
| |
| 09:56 | so I have to use xrandr -display :2 -q to get any output
| |
| 09:56 | is that the output you expect?
| |
| 09:56 | <alkisg> Yes, that will do
| |
| 09:56 | But don't set X_MODE_0 when you do that
| |
| 09:56 | Because that forces the display to only have 1 specific resolution
| |
| 09:59 | <BrechtM_> http://pastebin.com/nyj7jx8K
| |
| 09:59 | there you go
| |
| 09:59 | <alkisg> OK, now try these in your lts.conf:

| 10:00 | X_HORZSYNC=33-99
| |
| 10:00 | X_VERTREFRESH=50-76
| |
| 10:00 | XRANDR_MODE_0=1280x1024
| |
| 10:00 | XRANDR_RATE_0=60
| |
| 10:00 | Reboot and see if it works with and without the switch
| |
| 10:04 | <BrechtM_> works fine with the switch, xrandr -q output is the same
| |
| 10:04 | now testing with the switch
| |
| 10:06 | <abeehc> woo got the nx web applet goin
| |
| 10:10 | <BrechtM_> with the vga switch the effect is the same
| |
| 10:11 | xrandr output the same as well
| |
| 10:11 | <alkisg> Nice
| |
| 10:11 | Your monitor says that it also supports 75 Hz, you might want to try that too
| |
| 10:11 | <BrechtM_> I mean the effect is the same as it was, which is resolution 800x600 :)
| |
| 10:12 | <alkisg> Ah, then you either did something wrong, or you have a very broken driver
| |
| 10:12 | <Mip5> who
| |
| 10:12 | <BrechtM_> driver might be a factor indeed
| |
| 10:12 | <alkisg> On the client, try: ltsp-localapps xterm
| |
| 10:12 | <BrechtM_> it's a rather old machine
| |
| 10:12 | <alkisg> Ah sorry
| |
| 10:12 | <BrechtM_> dell gx150 of 7-8 years old
| |
| 10:12 | <alkisg> From the shell. You don't have an xterm :)
| |
| 10:13 | So, on the shell: lspci -nn -k | grep -A 2 VGA
| |
| 10:13 | That tells us your driver
| |
| 10:13 | And: getltscfg -a
| |
| 10:13 | That tells us that your lts.conf settings did reach the client (or not)
| |
| 10:14 | <BrechtM_> driver is VGA Compatible controller: Intel corporation 82815 chipset
| |
| 10:15 | getltscfg mentions the lts.conf settings I made
| |
| 10:15 | like Xrandr_rate etc
| |
| 10:15 | <alkisg> Sounds good. Can you pastebin your /var/log/Xorg.0.log ?
| |
| 10:16 | And also the result of `getltscfg -a`, if you can...
| |
| 10:16 | <BrechtM_> http://pastebin.com/26B0HyDV
| |
| 10:17 | xorg log
| |
| 10:17 | but before I made those xrand settings in the lts.conf
| |
| 10:17 | xorg.log of the client connected to the switch, that is. the one with the problems
| |
| 10:19 | <alkisg> Btw one easy way to paste: apt-get install pastebinit; getltscfg -a | pastebinit
| |
| 10:19 | <BrechtM_> that will be quicker, thanks

| 10:25 | <alkisg> That xorg.0.log was an old one, right? Can you pastebin your current one, that would show the new refresh rates?
| |
| 10:27 | I.e. we're looking to override this line, which has extremely low hsync range:
| |
| 10:27 | (II) intel(0): <default monitor>: Using default hsync range of 31.50-37.90 kHz
| |
| 10:28 | <Mip5> Okay - so I just checked my clients, and they show a different time before logging in (05:14), they have the correct time in the panel once they *are* logged in. So - I'll need to fix this in order for auto shutdown to work? Also - the clients don't even all have the same *wrong* time! What's the next step for me?
| |
| 10:28 | <BrechtM_> that xorg log is one of the client connected to the switch, before I added the xrandr settings to my lts.conf. I'll get a new one, now booted with the xrandr settings you told me. Just a sec.
| |
| 10:29 | <alkisg> Mip5: yes, you need to correct the time problem. The fix is here: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/1816
| |
| 10:30 | <Mip5> askisg: Thanks - I'll dive into it.

| |
| 10:35 | xorg log of the client with the switch booted with the xrandr lts.conf options
| |
| 10:35 | seems to be no difference
| |
| 10:35 | I suppose it defaults to those settings because it cannot detect the display?
| |
| 10:36 | <alkisg> Yes
| |
| 10:37 | Ah, maybe your ica script doesn't use the generated xorg.conf then?
| |
| 10:37 | ps aux => check the Xorg command line
| |
| 10:38 | <BrechtM_> I don't seem to find a line mentioning xorg
| |
| 10:38 | <pem725> I went through the entire troubleshooting page and confirmed tftpd was running and listening to the proper port, could retrieve a file on a booted client using a tftp client, and yet I still cannot boot other clients. This is on a LTSP network that was running rock solid for over 2 years without a hitch. I upgraded and had not problems with ltsp...until now. Any other hints?
| |
| 10:38 | <BrechtM_> it's an environment I inherited from my predecessor, I don't understand everything of it yet
| |
| 10:38 | <pem725> ltsp just times out.
| |
| 10:38 | <BrechtM_> would you have a look at the ica script?
| |
| 10:39 | it's one located in ltsp/screen.d
| |
| 10:39 | <pem725> oh, and dhcpd is definitely running because I get ip addresses and can see them sent out via /var/log/syslog.
| |
| 10:39 | <alkisg> BrechtM_: I don't see that file as part of ltsp-upstream, can you pastebin it?
| |
| 10:40 | <pem725> any help would be greatly appreciated.
| |
| 10:40 | <BrechtM_> it's a script my predecessor wrote to launch the ica client. It's based on the rdesktop script. Pastebin coming.
| |
| 10:41 | http://pastebin.com/PHyMLEvZ
| |
| 10:41 | the script launches a script called xinitrc.ica, I'm posting that too
| |
| 10:41 | thanks for your time, btw
| |
| 10:42 | <alkisg> It might be based on a very old rdesktop script. The current one has ${X_ARGS} in the xinitrc command line
| |
| 10:43 | <pem725> whoa! I fixed it by restarting networking...bizarre. Persistence pays off!
| |
| 10:43 | <alkisg> I think the xorg.conf location (in /var/run/ltsp/somewhere) is specified in X_ARGS
| |
| 10:45 | <BrechtM_> I see, it does
| |
| 10:45 | it is indeed based on a very old version of that script
| |
| 10:46 | <Mip5> alkisg: I followed the link, and edited the file. Should I rebuild the client image and reboot the clients to see if it works now?
| |
| 10:47 | <alkisg> Mip5: yes
| |
| 10:48 | BrechtM_: as a test, if you copy the generated xorg.conf from /var/run/ to /etc/X11, and restart X without restarting the client, it should then get a proper resolution
| |
| 10:49 | Or just put $XARGS right next to xinitrc and update your chroot...
| |
| 10:49 | <BrechtM_> I don't seem to have an xorg.conf
| |
| 10:49 | vagrantc (~vagrant@75.150.46.245) joined #ltsp. | |
| 10:49 | <alkisg> In /var/run/... something?
| |
| 10:49 | <BrechtM_> nope
| |
| 10:49 | <alkisg> Either /var/run/ldm, or /var/run/ltsp?
| |
| 10:50 | Hmm...
| |
| 10:50 | Let me check where that goes
| |
| 10:50 | <BrechtM_> I think it's somehow not generated
| |
| 10:50 | <alkisg> BrechtM_: which distro/version again?
| |
| 10:50 | <Gadi> alkisg: /usr/share/ltsp/xinitrc has to be called for xrandr params to work
| |
| 10:50 | <BrechtM_> is that possible, because of the strange/old way the wfica client is started?
| |
| 10:50 | ubuntu 10.4
| |
| 10:51 | <alkisg> Gadi: ah, ldm calls that?
| |
| 10:51 | <Gadi> yup
| |
| 10:51 | <alkisg> Hm. Maybe the easiest way is with XCONF then, for this case
| |
| 10:52 | <BrechtM_> ii ltsp-client 5.2.1-0ubuntu9 ii ltsp-client-core 5.2.1-0ubuntu9
| |
| 10:52 | <Gadi> just change the xinit line in the ica script
| |
| 10:52 | to be like the one in the current rdesktop script
| |
| 10:52 | <BrechtM_> ok I'll try that
| |
| 11:07 | ok the script starts fine with the added options
| |
| 11:07 | but there is no difference on the client connected to the switch
| |
| 11:08 | pem725 (~pem@129.174.97.34) left irc: Quit: Leaving | |
| 11:09 | <BrechtM_> I'll have to go now, though
| |
| 11:09 | thank you a lot alkisg and Gadi
| |
| 11:09 | I'll look into what the XARGS can do for me
| |
| 11:09 | and what other things might have to be changed to our ica script
| |
| 11:10 | I'll try an other client as well, might be that the detection is better there
| |
| 11:11 | <Mip5> alkisg: Well, I'm not sure it worked. My clients' hwclocks are still off, and not by the same amount. Is the patch supposed to sync them to the system clock?
| |
| 11:13 | <Gadi> BrechtM_: I came late to the game - is this a KVM switch that is causing problems?
| |
| 11:16 | <BrechtM_> not really a kvm switch but kind of: a switch which can switch between two inputs: the client and an other device. It's used in our classroom to switch between the ltsp client and a laptop
| |
| 11:18 | would the xrandr_disable option in lts.conf work now, when I add the X_ARGS to the xinit command?
| |
| 11:18 | I'll try that tomorrow :)
| |
| 11:18 | basically all I want to do is force the client to ignore it's autoconfigured monitor settings
| |
| 11:18 | but it doesn't want to listen
| |
| 11:19 | anyway thank you guys
| |
| 11:19 | we might meet again :)
| |
| 11:19 | <Gadi> right: well, the xorg log should also tell you what xorg.conf file it is using
| |
| 11:19 | <BrechtM_> keep up the good work
| |
| 11:19 | <Gadi> good luck
| |
| 11:20 | <BrechtM_> cya

| |
| 13:14 | <vagrantc> Gadi: is it run as the user? i.e. a user can't normally remove their own homedir

| |

| |
| 13:33 | TIMESERVER is not a variable, so yeah that's ok
| |
| 13:34 | If you use eval $(getltscfg -a), then you could do ntpdate $TIMESERVER. But it doesn't matter, just see if `getltscfg -a` returns the correct setting for TIMESERVER.
| |

| |
| 13:36 | <Mip> If I enter it w/out the ticks, I get TIMESERVER = "10.105.0.40"
| |
| 13:36 | <alkisg> OK, and below that, you see export TIMESERVER ?
| |
| 13:36 | <Mip> should ip address of TIMESERVER be in quotes? Mine is?
| |
| 13:36 | Yes - below that I see export TIMESERVER
| |
| 13:36 | <alkisg> Yes, it's ok that it is quoted
| |
| 13:37 | Now do: grep ntpdate /usr/share/ltsp/ltsp-init-common
| |
| 13:37 | | |
| 13:37 | Does it return exactly this? ^
| |
| 13:38 | <Mip> No! It looks like it returns the previous line (that I thought I deleted)!
| |
| 13:38 | <alkisg> OK, then that's why it's not working
| |
| 13:39 | <Mip> Right - but I double checked the file. Let me look at it again....
| |
| 13:42 | <Zarrku_> This is a new setup of ltsp installed from the edubuntu 10.10 iso.
| |
| 13:45 | <alkisg> Mip: you did reboot your client after running ltsp-update-image, right?
| |
| 13:47 | <Mip> alkisg: yes I did. I wonder if I somehow botched the edit or something. I just checked the file, and my change was *not* there. I just put it back in, and will rebuild the image and reboot the clients
| |
| 13:49 | <alkisg> vagrantc, Gadi, stgraber, btw LTSP clients, I think both in Ubuntu and Debian, don't get an "if-up" event, so scripts like /etc/network/if-up.d/ntpdate don't get to run (and also some upstart services). Should we fake an if-up event as part of the ltsp boot process?
| |
| 13:50 | <vagrantc> curious idea
| |
| 13:51 | <stgraber> we can't "fake it" when it should happen as that'd be in the initrd
| |
| 13:51 | but we can have ltsp's init script do a runparts on /etc/network/if-up.d/ or something
| |
| 13:51 | <alkisg> stgraber: not necessarily, e.g. for upstart we can emit a network-ready message (don't remember the exact wording)
| |
| 13:52 | And what you said about the if-up.d dir, and the respective network manager dir
| |
| 13:52 | <vagrantc> could just create a fake device and then ifup that...
| |
| 13:53 | then we don't have to second-guess the logic of how the ifup scripts rn
| |
| 13:53 | run
| |
| 13:53 | <stgraber> except that AFAIK it works the other way around on a regular system
| |
| 13:53 | as in, if-up.d triggers the net-device-up event in upstart
| |
| 13:53 | it's no upstart triggering if-up.d
| |
| 13:53 | <alkisg> Network manager triggers if-up.d on normal ubuntu systems
| |
| 13:54 | But we can look about "how" later,
| |
| 13:54 | first, would it be ok to do that? To somehow fake an if-up event?
| |
| 13:54 | Or should we better file bug reports somewhere else?
| |
| 13:55 | E.g. "network manager doesn't emit if-up events on netbooted systems" etc
| |
| 13:55 | <vagrantc> alkisg, stgraber: is there a more minimalist package to install on an LTSP server other than ubuntu-desktop that pulls in most everything?
| |
| 13:55 | i.e. i don't want xserver-xorg-* or gdm or any of that
| |
| 13:55 | <Mip> alkisg: Thanks man. I don't how I goofed that, but it's all working now.
| |
| 13:55 | <alkisg> Mip: you're welcome
| |
| 13:56 | <stgraber> vagrantc: not that I'm aware of. You could start with ubuntu-desktop --no-install-recommends but you'll still be missing a huge part of the desktop as pretty much everything is a recommend
| |
| 13:56 | <vagrantc> still pulls in gdm and xserver-xorg*
| |
| 13:57 | *sigh*
| |
| 13:57 | <stgraber> argh, yeah, gdm is a hard depend :(

| 13:58 | patrickmw (~pwright@ip68-231-4-153.ph.ph.cox.net) joined #ltsp. | |
| 13:58 | <alkisg> vagrantc: no X? Like e.g. ubuntu-standard?
| |
| 13:58 | <stgraber> alkisg: he said LTSP server, so I assumed that means including some kind of desktop environment, just without X server
| |
| 13:59 | * alkisg probably missed something there - where will the clients login to? | |
| 13:59 | <alkisg> Ah, is that possible? To install e..g gnome without X?
| |
| 13:59 | <stgraber> it should be possible to build a ubuntu-desktop-nox package using the same script that builds ubuntu-desktop
| |
| 13:59 | <vagrantc> essentially setting up an application server ... the thin clients are still running debian's LTSP ... just want an ubuntu box to log in to
| |
| 13:59 | <stgraber> alkisg: sure, you just need libX11, you don't need the X server or gdm to have a working ltsp
| |
| 14:00 | <Mip> Is there a way to have the time on the login screen show in our local time zone, rather than UTC?
| |
| 14:00 | <alkisg> OK - just thought that gnome and the other DEs would hard depend on X...

| 14:00 | <stgraber> vagrantc: if you want something easy to setup, I'd just go with a regular ubuntu desktop, install ssh, disable gdm. You'll be wasting ~150-200MB of disk space but that'll be easy to install at least
| |
| 14:00 | <Mip> excellent! Thanks gang!
| |
| 14:01 | <vagrantc> stgraber: yeah, that's probably the simplest thing to do
| |
| 14:02 | seems like it wouldn't be too hard to split the package into two packages: ubuntu-desktop-applications and ubuntu-desktop
| |
| 14:03 | would be useful for ltsp servers
| |
| 14:04 | <alkisg> !bot are you around?
| |
| 14:04 | Hmmm Scotty had progress with the pam stuff but not with the bot :)
| |
| 14:10 | <Mip> thanks again all - take care

| 14:21 | <muppis> Quick look at ubuntu-desktop depencies looks like removing xorg from list makes it what vagrantc wants as ubuntu-desktop-applications.
| |
| 14:22 | <vagrantc> removing gdm would be nice too
| |
| 14:22 | <muppis> Yes, somehow I missed that.
| |
| 14:24 | I can easily do that and put it my own repo, if you want?
| |
| 14:25 | <vagrantc> seems like at least filing a bug on ubuntu-desktop would be worth it
