| 11:23 | <ltspbot> 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

| 11:37 | <danboid> 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 :)
| |
| 11:38 | <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

| 19:31 | <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.

| 19:37 | <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)

| 19:56 | <alkisg> 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

| 20:37 | <dan_> Thats pretty much how I'm doing this installation except auth is handled by a Windows domain controller

| 20:38 | <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

| 20:57 | <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 / ...
