<alkisg>
nolaan_: all ok in your setup now?
16:09
<nolaan_>
hey alkisg yes but I havent installed anything yet because I wanted to rest a bit after this experience :D
16:09
however, what will happen if I install apache there?
16:09
I mean I wanna have a webserver on the server and accessible to the clients
16:10
But not run the apache server on the clients.
16:30
<alkisg>
nolaan_: you would just put RM_SYSTEM_SERVICES=apache2 in lts.conf
16:31
But in general, the ltsp server shouldn't be the same as the "big server" machine
16:31
It's more like the "teacher pc", if applicable
16:31
A template pc for the clients, that also happens to server their disk and home dirs
16:32
While apache/php/mysql/pfsense/whatever, belong to the other, "big server" machine
16:37
<nolaan_>
alkisg: RM_SYSTEM_SERVICES is used during ltsp-update-image, right?
16:37
<alkisg>
No, on client boot
16:38
All lts.conf variables get to the client when it boots
16:38
So while the client does have apache installed, its service is deleted on boot, and it's not runnable
16:38
<nolaan_>
there's no way to exclude this service during the image rebuilding process?
16:39
<alkisg>
Sure, you can put a cleanup.d/50-remove-apache script that apt purges apache
16:39
This would happen on ltsp-update-image
16:39
But why? To save 20 mb disk space?
17:11
<nolaan_>
just to not have apache there, It's like gcc i would prefer not to have it on the client too
17:11
all unnecessary services/tools
17:21
<alkisg>
A user can download anything from the internet anyway; it's not about disk space but about permissions
17:21
As long as you don't give them permissions to make programs executable or to run services etc, it doesn't matter if the code/files are there
17:21
They can get them from anywhere; the point is that they shouldn't be able to run them
17:21
But anyways sure you can remove whatever you want in the cleanup phase
17:22
(or from /etc/ltsp/ltsp-update-image.excludes)
17:25
It's also possible to maintain the ltsp template image in a vm, and use the "big server" to serve it and host apache and whatever else you want
