Nope, they can't. The rule is one IP address per IP interface. The only exceptions of this rules are: . ``pointopoint'' interfaces (SLIP, PPP), where the kernel considers the *remote* IP address for routing purposes, so this one must be unique for all connections of the local system (while the local address is largely irrelevant), and . IP aliasing, i.e. multiple IP addresses on a single ethernet interface. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
