I thought I had uninstalled telnetd (although it's possible I forgot to remove it).Having telnetd listening on port 1037 is definitely not normal. telnet listens for unencrypted connection on port 23 (as you mentioned) and can listen on port 992 if you're running a secure SSL enabled version. But not 1037.I'm thinking that somehow I've been broken into.Quite possibly.

Having telnetd listening on port 1037, if in fact it is, is probably not a good thing. Have you actually tried telnetting to that port ('telnet localhost 1037')?
Yes, and I'm able to login via that port.
Does 'netstat -tlnp' indicate that the process using that port is actually in "LISTEN" state?
