Yeah, unless you set the REUSEADDR socket option i think, then it can reuse the socket.

I wasn't aware that it could take over a socket that was actually in use, I had thought it just reused ones that were in the process of closing, but it sounds like my thinking is wrong.

So I think, using that socket option could be a bad thing most likely with SSH as synchronet could clobber sshd if it's running. It's unlikely that your setup is running a telnetd server, so in that instance it's unlikely to be a problem - but from what i understand in this thread, it's better to be safe than sorry.
