Thanks Jeff,
We have two network interfaces eth0 and 1,
Moreover would like to use Edubuntu 11.04 as it comes with many
educational software. When I tried installing Edubuntu 11.04 it took lot
of time without success.
Server already have Windows 2003 , Red Hat
and while installing Edubuntu, (had to use manual partitioning as earier
EDubuntu 10.04 was there) it got stuck at step where it kept saying
"removing conflicting files ...." and was at that for 40-45 mins. I had
to reboot and installed 10.04 then.
Does Ebubuntu 11.04 takes this long for installation and partitioning?
Did I miss anything?
Thanks,
Leena
