Comment (by Jaywalker):

 Replying to [comment:7 khc]:
 > it seems better to reverse the 2 ifs, so one of the duplicate check can
 be eliminated.

 I looked at that already and I ran into the problem of... if i is 8 (the
 last port) and the last port is the port we started with, it will
 increment that... Then the new incremented value becomes 9 which is out of
 range and must be caught. The "duplicate check" is only so we don't check
 if (altports[9] == deadport) and get an out of range exception. That's the
 only way my mind could think to do it... sketchy as it may be :-/
