OK, I got my students using ssh and scp. Then I showed them fish and all hell broke loose. They won't use the shell anymore...

One problem though, for some reason some of my students could not access their files remotely in this fashion. It looks like some sort of networking error where the "connection is refused" or "connection closed by remote host." What would cause this? I've never had any networking problems using KNOPPIX in my lab before either for printing or for using the internet. So why a problem like this over the "intranet" (ie: LAN)?

If I can't get this to work, I'll have to break down and knx-hdinstall each PC so I can use x-clients and an x-server. I was looking into PXE, but what a complication!
