lowercase-mac: The new ltsp.conf expects mac addresses in lowercase. Here's a command to convert them: sed -E 's/([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}/\L&/' -i ltsp.conf

alkisg, Morning!
11:37
<alkisg>
Hey danboid
11:37
<quinox>
I'm still on the old LTSP, I have `"$CHROOT_DIR/usr/bin/getltscfg" --configfile "$LTS_CONF" --all` in my cron to notify me when I make break the file :)

<danboid>
Did you see my message about getting the auto ZFS home partition creation working with LDAP + PAM?
11:39
alkisg, However this is in a VM with ZFS mounted a a local disk. Do you expect the same script should work for LTSP clients with ZFS /home mounted via sshfs or might I have to use ZFS over NFS?
11:40
alkisg, https://askubuntu.com/questions/1379930/how-to-create-zfs-home-dirs-using-pam-exec
11:41
<alkisg>
I saw the message although briefly, I'm still too much time-pressed currently.
11:42
If you're modifying pam_exec on the server, then sure it should also work on ltsp
11:42
If you're modifying pam_exec on the client image, then you need to make sure it doesn't remove the password from the stack, so that sshfs can read it
11:43
<danboid>
alkisg, Removed which password?#
11:44
The pam login password?
11:44
<alkisg>
Yes
11:44
From the pam stack...
11:45
<danboid>
The pam_exec script will need to be run server side so hopefully I can run the script via ssh OK
11:48
Todays the day I'll finally be installing LTSP on our new LTSP server. I've spent weeks preparing the network, disks etc etc.
11:48
Its got a 10Gb fibre link to our our LTSP server which I'm going to re-install when the new one is up
11:48
*our old
11:49
Weeks on and off

<Hyperbyte>
danboid, you should really consider virtualizing your LTSP server(s)
19:32
I'm currently upgrading one of our clients from Ubuntu 18.04 to 20.04 and they're not even realizing it... better yet, I'm not even on location while working on the 20.04 environment. I boot a virtual PXE client to test.

<danboid>
I don't feel comfortable doing thatm performance would suffer a bit, more scope for problems
19:37
I can't justify the extra issues over potential gains
19:38
<vagrantc>
virtualization barely has any impact on performance with modern (e.g. 10 years+) hardware
19:39
and huge advantages for maintainability
19:55
<alkisg>
It's also easier to do snapshot + test upgrade + rollback on failure on VMs
19:55
But it does add a bit of maintenance overhead, so e.g. I don't use it on schools, there's no need for them to maintain 2 operating systems (host+guest)

For big installations, my ltsp servers are bare metal plain zfs /home, while authentication is in an openldap vm, and the ltsp image is in another vm

<dan_>
Thats pretty much how I'm doing this installation except auth is handled by a Windows domain controller

<dan_>
I don't want to have to use virtio or NFS to link my ZFS pool to VM or container running LTSP
20:38
It just feels yuk
20:39
I use LXD and proxmox elsewhere but I don't want it here

<alkisg>
You could bind the physical partitions, but since debian/ubuntu don't really break on upgrades, I don't see the reason to....
20:58
We also have backup servers around, so it's not a problem if we put a primary server offline for 5 mins to clone a broken / ...
