Install Epoptes on Multiple Thin Client Servers

Asked by Oliver Webb

Hi,

We have a setup where we have two thin client servers, and clients can boot from either of them depending on the load at the time.

This results in having a computer suite where the computers can be running of either server.

How you would advise setting up Epoptes in this environment, so that the all the computers in the suite can be monitored from a single server?

Many thanks,

Ollie

Modify /etc/default/epoptes-client in the second server, both in / and in the chroot, so that it points to SERVER=ip-of-server1.
That way all Epoptes clients will be connecting to server1, no matter where they've booted from.

Then either do LDM_SERVER=server1 for teachers in your load balancing logic, or do the following:
Create a /usr/local/bin/epoptes wrapper in server2, that does:
#!/bin/sh
exec ssh -X server1 epoptes "$@"
Don't forget to make it executable, by running `sudo chmod +x /usr/local/bin/epoptes`.
Finally, set up passwordless ssh authentication for each teacher from server2 to server1:
teacher@server2:~$ ssh-copy-id server1

Thanks, that sounds perfect. Have already got Epoptes running in our fat client rooms, and the teachers love it!
