I think I know this one... Make sure that the sockaddr struct that
you feed to bind() is fully zero'd out (using memset() or bzero())
before you assign the needed fields. Otherwise, bind() complains
because it sees garbage in the other fields.
This is a problem common to code which was originally written for
BSD on VAXen, a platform that was extremely forgiving of bad coding
practices (assuming memory was automagically initialized to all zeroes,
dereferencing NULL pointers, using malloc(0), etc. etc.). I've been
bitten by just about all of them at one point or another... and the
Kerberos V4 code does them all... :-(
