Mea culpa ... A few minutes of experimentation allowed me to prove myself wrong. Even client code can call bind() to prefer a source endpoint... search through perlipc for the trivial TCP client and add the following line: bind(SOCK, sockaddr_in((0, inet_aton('192.234.345.456'))) || die "bind: $!"; between the calls to socket() and connect(). Obviously you'll need to replace that bogus IP-addr with the ip-addr of your local interface. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Lawrence Statton - [EMAIL PROTECTED] s/aba/c/g Computer software consists of only two components: ones and zeros, in roughly equal proportions.
