Under FreeBSD, IP aliasing is a snap. Simply type something like: "ifconfig <interface_name> alias <ip_address>" It works pretty darn well, and has saved my butt in a couple cases. The only possible snag is if you have an entire subnet you need to alias (rare, I know), in which case you need to create an alias on that interface for *every* host in that subnet separately. Hope this helps. --Anindya |-------------------------------------------------------------| | Anindya Chakraberti | | Business Services Network Engineer | | Mindspring Enterprises Inc. | | Atlanta, GA | | anindya@mindspring.net | |-------------------------------------------------------------|
