That won't be a good solution in practice. When passive mode doesn't work, it's almost always because a firewall on the server side is blocking the incoming data connection. The client doesn't see a refusal; its connect() call just times out. The trouble is, the timeout takes a long time (on the order of a minute or more). John -- John Polstra jdp@polstra.com John D.
