| 07:35 | <Vlad__> hello, i have a problem with OCS Inventory Agent on LTSP-clients
| |
| 07:36 | we have 2 types of clients:
| |
| 07:36 | 1) with desktop environment (XFCE-clients)
| |
| 07:36 | forum has left IRC (forum!~Icedove@194-118-45-234.adsl.highway.telekom.at, Quit: forum) | |
| 07:36 | <Vlad__> 2) without desktop (and without user profile) that boot directly into xfreerdp (xfreerdp-clients)
| |
| 07:36 | both run Debian 8 and have OCS Inventory Agent installed
| |
| 07:36 | XFCE-clients report to OCS-server each day without issues
| |
| 07:37 | but xfreerdp-clients report until they are shut down only
| |
| 07:37 | i.e. if a user powers off his PC at the end of the working day and the next morning he starts it
| |
| 07:37 | "/etc/cron.daily/ocsinventory-agent" script won't be triggered

| 08:43 | <alkisg> Vlad__: wouldn't that be an OCS issue, to ask in their channel etc? Do you think it's related to LTSP?
| |
| 08:50 | <Vlad__> i don't know, as i've said OCS on desktop clients work well so i thought the problem has something to do with LTSP running without desktop environment
| |
| 08:51 | forum has joined IRC (forum!~Icedove@62-47-176-103.adsl.highway.telekom.at) | |
| 08:51 | <alkisg> Vlad__: cron daily jobs run without any relation to the desktop environment (and to ltsp)
| |
| 08:51 | Are you using the same chroot for both tasks?
| |
| 08:53 | <Vlad__> no, there're different chroots for each client type
| |
| 08:54 | <alkisg> You don't really need different chroots there, but ok
| |
| 08:54 | Are you using some RM_SYSTEM_SERVICES directive in lts.conf?
| |
| 08:54 | That would delete cron jobs?
| |
| 08:55 | <Vlad__> nope
| |
| 08:55 | <alkisg> There is one case where ltsp clients don't run cron jobs, when the RAM is extremely low, I think <= 128 MB. Your clients don't have that low ram, do they?
| |
| 08:55 | <Vlad__> at least 512 MB
| |
| 08:56 | <alkisg> OK. Well, the next things I would do would be: (1) check the client syslog to see if cron jobs are ran or not, and (2) try to run "/etc/cron.daily/ocsinventory-agent" manually to see if it produces any errors
| |
| 09:01 | <Vlad__> i've checked logs and daily jobs indeed didn't start on freerdp-clients
| |
| 09:01 | but on xfce-clients they did start
| |
| 09:02 | <alkisg> Put the output of `getltscfg -a` to pastebin for both types
| |
| 09:02 | Btw, are XFCE clients thin or fat?
| |
| 09:02 | <Vlad__> fat
| |
| 09:03 | <alkisg> OK
| |
| 09:03 | You could also check the output of `getltscfg -a | grep cron`
| |
| 09:03 | But pasting the whole `getltscfg -a` will allow us to see more
| |
| 09:04 | (of course, put ** in case of any passwords you might have there)
| |
| 09:10 | <Vlad__> desktop client : http://pastebin.com/kBAK8AzX
| |
| 09:10 | without desktop: http://pastebin.com/UzTcMtBu
| |
| 09:12 | <alkisg> Eeeh you run xfreerdp while setting fat client (which isn't appropriate), and setting SOUND=true without having a thin client... a bit of a mess there
| |
| 09:12 | But anyway, those shouldn't matter about cron jobs
| |
| 09:13 | Does `service cron status` mention that cron is running?
| |
| 09:14 | <Vlad__> yep, it's running
| |
| 09:16 | <alkisg> If cron is running but it doesn't execute the daily jobs, it sounds like a cron misconfiguration
| |
| 09:17 | LTSP shouldn't be related to that issue
| |
| 09:19 | <vlt> Hello. I use SCREEN_XX in lts.conf for "ldm" or "rdesktop ..." logins. Now I tried another command that works perfectly in a local xterm shell but gives me "Script 'x2x' for SCREEN_07 was not found". I’m doing it wrong obviously.
| |
| 09:19 | What do I have to put as a command there to run an X server with the x2x command on SCREEN_07?
| |
| 09:20 | <alkisg> vlt, you would need to create your own screen script
| |
| 09:20 | Check /usr/share/ltsp/screen.d/
| |
| 09:20 | You would need to add one script there
| |
| 09:22 | <vlt> alkisg: Ah, ok. So "rdesktop" are "xfreerdp" not simply run as a command. These are scripts. Thanks!
| |
| 09:22 | <alkisg> Yup

| 09:27 | Vlad__ has left IRC (Vlad__!c2e28421@gateway/web/freenode/ip.194.226.132.33) | |
| 09:40 | <vlt> Great!
| |
| 09:41 | I took the xterm script as a template, replaced "xterm" with my "x2x" command. Works!
| |
| 09:41 | alkisg: Thanks!
| |
| 09:41 | <alkisg> :)
| |
| 09:42 | <vlt> Any idea if it’s possible to force a ridiculously narrow X screen size like 8 px?
| |
| 09:42 | <alkisg> Do you mean screen resolution?
| |
| 09:42 | <vlt> alkisg: Yes.
| |
| 09:42 | <alkisg> Like, instead of 1024x768, to have 8x8?
| |
| 09:43 | <vlt> Yes, or 8x768
| |
| 09:43 | The client I’m running x2x on has no own screen.
| |
| 09:43 | It just controls another one via x2x.
| |
| 09:44 | So it would be very convenient if the space of the mouse cursor "missing" on the "wrong" screen would be minimal.
| |
| 09:45 | * vlt asks in #xorg | |
| 09:47 | <alkisg> I didn't understand the setup...
| |
| 09:50 | <vlt> alkisg: I have one headless client. On that I run "x2x -to another_client:7.0 ..."
| |
| 09:50 | The other client has no keyboard or mouse and is controlled by the headless one.
| |
| 09:50 | <alkisg> If it's headless, then xorg isn't running directly there
| |
| 09:50 | There's no concept of screen resolution there
| |
| 09:51 | <vlt> Sorry, "headless" meant "no connected screen".
| |
| 09:51 | <alkisg> Ah
| |
| 09:51 | So if you actually connect a screen there, you'll see the 8x768 resolution
| |
| 09:51 | <vlt> So, X starts just fine.
| |
| 09:52 | Then I would see the 8 px wide X screen, yes.
| |
| 09:52 | x2x is configured to have the "remote" X to the right/east of the own screen.
| |
| 09:52 | forum has joined IRC (forum!~Icedove@62-47-176-103.adsl.highway.telekom.at) | |
| 09:53 | <vlt> That means that I can move the mouse far to the right and control the other (= visible) X screen.
| |
| 09:54 | The smaller I can force the "local" (no monitor connected) X screen, the less annoying situations of "my mouse is missing" do I get.
| |
| 09:54 | The mouse is "missing" when the user moved it to the left onto the invisible X screen.
| |
| 09:54 | alkisg: I hope I could clear that up a little ;)
| |
| 09:57 | <alkisg> Moment, school needs support..

| 10:59 | <vlt> Wait ... I just read x2x's man page again. Seems the "-east" option is optional and I should get exactly what I need by removing that.
