Or use L2 connections and DHCP. They don't get a chance to screw it up then.
Or see my other suggestion: separate GLAN/VSWITCH segments. At least the
student can only screw themselves that way.

Thanks to all of you that provided your input. Looks like there is no
very simple way to avoid this. We did use one tactic that was suggested,

I was thinking about it yesterday, and come with this: what if you assign
the guests to a vswitch with isolation mode turned on and put the FTP
server in another interface? The guest with incorrect IP would not "poison"
the ARP cache of everybody, and you could configure your gateway to drop

Just write in the wall:
"People using incorrect IP address will be shot in the head."
That's what I do, and not even one duplicated IP occurred since then...

Yep. If you have all the students on the same segment, and somebody ARPs for
the VM address and gets it, you lose until you can get the VM stack to ARP for
it again.

Don't you think the Linux guests finally used all allocated memory and one

Hi List,
Just attempting to do my first SLES11 install and the install process keeps on
prompting for all sorts of information even though a PARMFILE is provided. It
almost looks like the PARMFILE is being ignored.
