Check out http://aggregate.org/FNN/ They have stuff about multi-NIC per box, each box connected to every other box through at least one 1-switch path. -- #define X(x,y) x##y Peter Cordes ; e-mail: X([EMAIL PROTECTED] , ns.ca) "The gods confound the man who first found out how to distinguish the hours!
