I never wandered into the world of Unix sockets programming. But redirection should not be too difficult. A daemon listening on udp port 20000, which sends the received UPD datagrams out again to user.domain.org:20000. Several weeks ago Richard Stevens' books on Unix network programming were mentioned as an excellent resource for this type of thing. ===Janko van Roosmalen - Vught - Netherlands=== On Sat, 30 Sep 2000, Louis Valentine wrote: > > Here's the scenario: > > I have a box running FreeBSD 4.1-RELEASE with a single interface (ethernet > card).
