FR--> Yes you can, I just had to do that for a Solaris customer who was currently on a class C and needed to start migrating to a class B on his net. I setup the solaris box with an alias /etc/hostname.iprb0 and /etc/hostname.iprb0:1 and then had to append the new network number and mask in /etc/netmasks where the first line applied to the first true interface and the second line to the aliased, I got lucky there for I didn't know how to designate what line in /etc/netmasks to what interface. I did the same on a Linux box with `ifconfig eth0:0 <ipaddr> broadcast <bcastaddr> netmask <nmaskaddr> up` And was able to communicate (ssh/telnet) on the new network. I have NOT done it with FreeBSD though. -- Bill Schoolcraft PO Box 210076 -o) San Francisco CA 94121 /\ "UNIX, A Way Of Life." _\_v http://forwardslashunix.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
