Thanks, John. This makes a lot of sense -- I'll have to give it a try. I ended up taking an uglier approach. First I set up keys pairs with my forwarding server so I don't have to log in. So no more need for pexpect at this point. I then set up an ssh connection with a "-f sleep 10" option. This backgrounds the connection to the forwarding server and runs "sleep 10" on the forwarding server, which gives me 10 seconds to log in to my forwarded port (localhost 2022). 10 seconds is actually probably excessive, since logging in is the next command in the script. The connection then stays open so long as I'm logged in. It works, but it seems rather kludgey. So I'll definitely give your approach a try.
