alkisg: hello again, I have a question when you use virtualbox for ltsp, do you get a message saying a new image is available each time you logout ?
03:23
alkisg: sorry to bug you again, I have done some reseach and can't find an answer for this: how can I get the keypad to work. I have numlock on and it does not type numbers unfortunately...

<alkisg>

05:55
onixx: X_NUMLOCK=True
06:06
<onixx>
alkisg: I have tried this and same result
06:06
alkisg: problem on both the vm and the laptop
06:06
<alkisg>
onixx: does keypad work if you turn it on manually by pressing numlock?
06:07
<onixx>
alkisg: no.
06:07
<alkisg>
Well then it's not related to ltsp
06:07
Ask in #ubuntu or something
06:07
Or in #hardware
06:08
<onixx>
alkisg: maybe xfce4
06:08
<alkisg>
Try in ldm
06:08
While typing the username
06:08
This is not related to any desktop environment

06:35
probably vnc acting up
06:35
<alkisg>
yes, vnc often breaks keys

<onixx>
Hello again. I was wondering if I can run epoptes on one of my fat clients vs directly on the server screen ?
15:54
<alkisg>
Yes, read the docs on its site
15:54
epoptes.org/documentation
15:58
<onixx>
alkisg: thanks. I will give it a shot
16:16
<ian_j>
does ltsp use aufs or overlayfs currently?
16:17
<alkisg>
ian_j: overlayfs, because aufs isn't very available nowadays
16:17
<ian_j>
ok thanks
16:17
<alkisg>
It also supports aufs
16:17
You just need to install aufs manually, and ltsp uses it
16:18
Which distro are you interested in?\
16:19
<ian_j>
I was using Centos last time.
16:19
I wasn't really using ltsp for its intended purpose. I was attempting to launch diskless webserver instances
16:21
<alkisg>
I'm not sure about centos, it might e.g. be using unionfs or something else
16:21
I was talking about debian/ubuntu
16:21
<ian_j>
If I was to do it again I would probably use debian as my starting point
16:25
I never quite understood how ltsp was able to keep the node information for multiple clients
16:27
I'm guessing there is some clever way of using the union fs and storing the node data by mac address or something
16:27
<alkisg>
I don't know what "node information" means for you\
16:27
LTSP root file system is not writeable
16:27
<ian_j>
desktop state for a particular login/computer
16:27
or logs etc
16:27
<alkisg>
/home/username is saved via nfs/sshfs
16:28
Logs etc aren't saved
16:28
No machine state
16:29
<ian_j>
that's a bit of an issue for a webserver
16:29
I guess it would be possible to use syslogd to write them to another server for monitoring
16:32
<alkisg>
ltsp supports forwarding syslog from the clients to the ltsp server
16:32
<ian_j>
ah, is that an option or on by default?
16:33
<alkisg>
Option in lts.conf
16:33
lts.conf is the configuration file for all clients
16:33
<ian_j>
I didn't know of that option or I'd certainly have tried it
16:33
<alkisg>
You can also forward more dirs except for /home/username, via nfs/sshfs
16:34
<ian_j>
what happens if you forward something like /var?
16:34
would each ltsp client attempt to use the same dir?

16:59
<alkisg>
yes, and it would fail because locks that go in var don't work reliably over the network\
17:00
If you want such things, you could export an nbd state image per client
17:00
writeable
17:00
E.g. an nbd for /var and /srv
17:10
<ian_j>
that sounds like what I needed, and yes, I ran into all kinds of issues with file locks when experimenting.
17:11
certain files needed to be writable for the mail system etc and weren't with what I had at the time
