Ahh.. now this I can believe, I vaguely recall seeing something like this.
I've also seen the mouse play up. Of course the usual recourse is to apply
all the errata. Seems like there's been heaps of updates since RedHat 9
was released. Umm I can't remember if you said it was a RedHat system now.

Still worth testing but it would have to be pretty poor, or faulty nic to

Yeah... this contradicts the MTU theory above too. The symptoms with SCP
are usually more like "small files are fine, but when it goes more than
about 20K it slows to a crawl or stops"

My condolances. Just leave the girlfriend's PC running Linux and do all
those downloads on her ADSL, then you've got an excuse to visit every day
to burn a CD <grin>.
