Thanks, everyone.

Like I said, I know nothing about sockets and realize now I probably
should have asked this question elsewhere. I assumed it was not a
problem with ruby, but couldn't figure out what was wrong. I thought I
had set up a process to listen on each port that I tried, but I had
not.

Yes, Bob, I meant to type 'ftp' in quotes.

I wasn't trying to do anything except send data over some sockets with
ruby. Just playing.

Thanks again,
