Huh?? Are you referring to my e-mail address? Believe it or not, it's a
real working one, its whole point is to have spammers remove it from their
lists thinking it's bogus ;-p Oh, and I'm a Monty Python fan, those who
know the viking spam sketch have probably already figured :-D

This doesn't work for me. The ctc kernel module doesn't even get loaded
automatically, and when I modprobe it, I only get a single line :

CTC driver Version: 1.61  initialized

It doesn't say anything about ctc0... nor does "ifconfig -a" report any, as
if the device wasn't emulated properly, but running the network install
with the same nercules.cnf works fine. Maybe I could try the LCS network
interface instead? Has anyone had any luck with it using hercules?
