Quite a few programs let you do it: telnet, bind, postfix, lyris, to name a few. Curiously, I had bind running bound to an alias interface for legacy purposes for a while. For kicks one day, I turned on log_in_vain for udp, and was getting *lots* of udp packets to the primary address. I had to tell bind to just go ahead and listen on all interfaces, yet still use only the alias for outbound messages. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
