| 05:06 | <alkisg> (10:13:57 PM) ***vagrantc suspects in other distros /usr/libexec might be more appropriate than /usr/share ==> heya, isn't "/usr/share" for platform independent data that can in theory be shared by multiple installations, such us our shell scripts?

| 07:55 | <vagrantc> alkisg: i don't recall the details, but i've had some people from other distros insist that code doesn't belong in /usr/share ...
| |
| 07:56 | <alkisg> vagrantc: np, it'll be flexible, but it does sound against what the fhs says
| |
| 07:56 | <vagrantc> gotta head, though

| 13:19 | <nikoh77> hi guys, with epoptes i can shutdown my fat clients, what is the command that ia can execute with cron for shutdown all clients?
| |
| 13:22 | I would like to set an automatic server restart every night...
| |
| 13:25 | spaced0ut has joined IRC (spaced0ut!~spaced0ut@unaffiliated/spaced0ut) | |
| 13:35 | <quinox> <alkisg> RCFILE_SHUTDOWN="shutdown -h 14:00" ==> shuts down the clients even if they have logged in
| |
| 13:35 | that goes in the lts.conf
| |
| 13:37 | <nikoh77> quinox: this command shutdown all active fat clients?
| |
| 13:38 | <quinox> after they booted
| |
| 13:38 | the RCFILE_* puts your lines into /etc/rc.local
| |
| 13:39 | so what this does is on startup when /etc/rc.local is executed schedule a shutdown at a certain time
| |
| 13:41 | you can run 'shutdown -h 15:42' on a fat client as root to test it
| |
| 13:41 | after putting it in lts.conf and booting a client you should be able to see the command inside /etc/rc.local
| |
| 13:44 | <nikoh77> quinox: in my lts.conf i see SHUTDOWN_TIME 2:00:00, this work?
| |
| 13:45 | <quinox> that shuts them down when they are at LDM at that time
| |
| 13:45 | so stations that are not logged in at 02:00:00 gets shut down
| |
| 13:46 | if you are rebooting your server you want to shutdown all clients, not just the idle ones
| |
| 13:46 | <nikoh77> ok, understood
| |
| 13:46 | thanks
| |
| 13:48 | quinox: so, to shutdown all clients (logged and not) i must two commands: shutdown_time and rcfile_shutdown...
| |
| 13:48 | right?
| |
| 13:48 | <quinox> the RCFILE_SHUTDOWN is enough, it shuts down all clients
| |
| 13:49 | <nikoh77> thhhanks

| 16:09 | <nikoh77> quinox, can i export extra folder per user? Like user a extra folder a and user b extra folder b?
| |
| 16:10 | <quinox> besides the home folder?
| |
| 16:11 | <nikoh77> no
| |
| 16:11 | yes
| |
| 16:11 | sorry, yes, in home root
| |
| 16:11 | <quinox> there are some tricks
| |
| 16:11 | <nikoh77> in /home, not in /home/usera
| |
| 16:12 | <quinox> fe. you can run specific commands based on MAC address using lts.conf
| |
| 16:12 | <nikoh77> now i use export extra folder but all can see these dirs...
| |
| 16:13 | yes, i know but is it possible for user not mac based?
| |
| 16:13 | <quinox> bind-mounts inside /home/user might or might not work, depending on how the home folder is accessed on the client
| |
| 16:14 | there are no user-based extra commands / mounts that I know of
| |
| 16:14 | there is a lot I don't know about LTSP though :)
| |
| 16:14 | <nikoh77> ok thanks
| |
| 16:15 | <quinox> every user has ~/.xsession that you can use, but it's controllable by the user so it's not safe at all
| |
| 16:15 | you can use sudo commands limited to specific users, that might be safe
| |
| 16:17 | this might be overengineering things, but you can write a small /usr/local/dostuff script that users can sudo execute, which checks who the user is to determine what to do
| |
| 16:18 | then call that from inside /etc/X11/Xsession.d/ maybe?
| |
| 16:18 | Linux usually allows you to do pretty much whatever you want, as long as you put some effort into it :)
| |
| 16:19 | <nikoh77> mmmm is too hard for me ;-)
| |
| 16:19 | i set right permission on folders...
| |
| 16:23 | <alkisg> nikoh77: you can have symlinks from the user desktop to /home/shared/user
| |
| 16:23 | That way, each user can have his own shared dir
| |
| 16:23 | !extra
| |
| 16:23 | <ltsp> Error: "extra" is not a valid command.
| |
| 16:23 | <alkisg> !EXTRA
| |
| 16:23 | <ltsp> Error: "EXTRA" is not a valid command.
| |
| 16:24 | <alkisg> !lts.conf
| |
| 16:24 | <ltsp> lts.conf: (#1) http://manpages.ubuntu.com/lts.conf, or (#2) lts.conf manpage is available in the ltsp-docs package
| |
| 16:24 | <alkisg> LOCAL_APPS_EXTRAMOUNTS there
| |
| 16:24 | You share /home/shared with that, and you symlink to /home/shared/user
| |
| 16:25 | <nikoh77> yes, this is my configuration but all user can see the folder in /home
| |
| 16:26 | <alkisg> nikoh77: you can set up permissions so that they don't see it
| |
| 16:26 | Note that users can still ssh to the server and see whatever you have there if you don't set up permissions
| |
| 16:26 | So if you don't want them to see other folders, you need to set proper permissions anyway
| |
| 16:27 | <nikoh77> now /home/shared is 770, so all users can see but not access
| |
| 16:28 | <alkisg> And where's the problem with that, with ltsp?
| |
| 16:28 | woernie has left IRC (woernie!~werner@pD9E8BADB.dip0.t-ipconnect.de, Remote host closed the connection) | |
| 16:36 | <alkisg> I think maybe you need to describe both the goal and the problem better... I'm not sure I understood it
| |
| 16:37 | <nikoh77> alkisg, ok, before i try some tricks ;-)
| |
| 16:37 | thanks
