Ahhhhhhh. That wasn't quite the cause -- I'd already tried quite a few cat 5e cables -- but it was related to the switch. After messing around for very nearly 24 hours I've learn an important rule. Don't put a gigabit switch near, or on top of, a 1200VA UPS. Judging by the effect they have on a monitor they produce some pretty hefty electro-magnetic fields. Thanks a lot for the help all, apologies for the noise :( -- Cheers, Chris Howells -- howells@kde.org Web: http://www.kde.org.uk, PGP ID: 0x33795A2C KDE/Qt Developer: http://www.kde.org
