Hi again
10:08
quick quesiton, if I add a new script file inside /usr/share/ldm/rc.d/
10:08
do I need to do anything in particular for this script to get picked up by ldm ?
10:08
and do I need to rebuild the image for that to get included in the clients ?
10:10
I actually got the answer to question 2 and it’s yes but what about question 1 (do I need to do anything specific for it to be executed ?)
10:10
also how to debug a script that is placed there ?
10:13
well ok got my answer to question 1 (it’s been executed automatically :-)
10:13
and I didn’t need to debug, the code worked directly

alkisg: is it possible to have epoptes minimize to an icon in the tray, rather than a full window space?

<julienfayad>
hey again, so I’ve implemented my solution (copying the ccache file to the /tmp folder of the client) and that works great so far
17:14
only glitch is that at logout the file isn’t being deleted…
17:14
thing is I don’t know if there is a script/rc.d folder that gets called at logout and which one it is
17:15
so I can just delete the ccache file of the user who is logging out
17:15
anyone could guide me ?
17:18
<alkisg>
julienfayad: less /usr/share/ldm/ldm-script
17:18
The various stages are there
17:18
K* is logout, but I'm not sure if it's guaranteed to run or not (e.g. on Xorg crash)
17:18
So better put it at I*
17:19
E.g. /usr/share/ldm/rc.d/I00-clean-ccache

Thanks a lot alkisg! I’ll try this out

<MeLLy>
Question. We want to run multiple ltsp desktop servers with one dhcp server. I see where you can put the directive SERVER=IPADDRESS in the lts.conf. Is that all you have to do? We try it and the thin client doesn't boot into the desktop
18:12
<alkisg>
MeLLy: how do you plan to divide the clients to servers? Randomly? Via mac address?
18:12
<MeLLy>
via mac
18:12
I tried doing that with [00:00:00:00:00:00] and then the SERVER=IPADDRESS underneath
18:13
It didn't like that at all
18:13
<alkisg>
Then you can specify the server in the "next-server" field of your dhcp server
18:13
You can also specify it in pxelinux.cfg/default, in nbdroot=ip:/opt/ltsp/i386
18:13
Then you can specify it in lts.conf, in [mac] SERVER=ip
18:14
And finally, in [mac] LDM_SERVER=ip, if you only want one nbd server and multiple application servers
18:14
<MeLLy>
Ok let me give that a shot real quick
18:14
<alkisg>
But in general, it's best to use better CPUs on the clients, i.e. boot them as diskless ltsp fat clients, so that one server is enough for lots and lots of clients
18:16
<MeLLy>
Do I put the next-server in the global directive of the dhcpd.conf? Or is that added on to each host you want to send to another server?
18:16
<alkisg>
I'm not using dhcpd.conf, but dnsmasq. You should put it on groups (one group per server), and then assign the clients to gropus
18:17
So that each host is assigned to a group which represents a server
18:26
<MeLLy>
Okay, so now I've gotten a little further but it says: nfsmount: need a path
18:31
<alkisg>
MeLLy: which distro/version is that? E.g. Ubuntu uses nbd by default, not nfs
18:32
...newest debian too
18:32
<julienfayad>
actually alkisg after reading the ldm-script I the command for I scrips is LDM has just started, X is running, the greeter isn't
18:32
<MeLLy>
Well the dhcp server is running centos 6 while the desktop servers are going to be debian 8
18:32
<julienfayad>
this is what will happen after a user logs out ?
18:34
and in that case can I know the uid of the user who logged out ?
18:34
(it might not be important but simple curiosity)
18:34
<alkisg>
julienfayad: yup, I know, I wrote those comments :) After logout, K happens, then a new cycle begins and I happens
18:35
You can probably get the uid in K* with LDM_USERNAME, but as I said, I'm not sure if K* is guaranteed to be executed
18:35
<julienfayad>
ok in I all information about the user are gone since the new cycle is starting
18:36
<alkisg>
MeLLy: do specify the root-path as well, e.g. root-path=/opt/ltsp/i386
18:36
<julienfayad>
so basically this will get executed also at the very first time LDM shows
18:36
<alkisg>
MeLLy: keep in mind that I don't know the dhcpd.conf syntax, so you may need to google for the exact name of root-path
18:41
<MeLLy>
Okay, you hit the nail on the head. I had to add "option root path" to the ltsp client in dhcpd.conf
18:41
Now it boots! You are awesome. Thank you!
18:46
<alkisg>
You're welcome
18:51
<julienfayad>
and things work well by my side too :-)
18:51
Thanks Alkisg
18:51

18:52
<alkisg>
:)
18:53
<julienfayad>
well it’s a bit hacky as a solution but that works, I’ll post an issue on launchpad
18:56* alkisg will ignore the issue until he gets an answer to the question he asked about kerberos :D

yup you are right, well I’ll open the issue and point it out to Kerberos people so the discussion could happen on the issue queue directly
19:42
might be more productive there
