 - Check the actual numerical address,
   instead of assuming that undefined is written down "".
 - Resolve remote peer before messing with sockets, and do it only once.
 - Do not try to connect to remote peer when SSM join succeeded
   (I do not feel like guessing which OSes besides FreeBSD didn't like this).
 - Do not assume that address are in numerical notation for SSM.

- it doesn't work neither on FreeBSD 5.4 nor on FreeBSD 4.11:
      cannot connect socket (Can't assign requested address)

Retain connect() as fallback in any case.
