I've got a friend who's having trouble dialling up. They connection
dials ok, makes handshaking noises and then disconnects with "bad
authentication".

We've checked, double checked, everything is fine on the ISP side,
they gave us a test account, tested with another ISP (still using
Telstra's MegaPOP VISP stuff), changed V34, removed echo packets...

ISP can't see any connection attempts at all.

Any ideas?
