I have had little sleep so this sounds like a riddle. Anyways ...

Use "netstat -an" to verify what ports and IPs these two services are 
listening on the local system.

Verify that you don't have any packet filter stopping this. (Look at 
"iptables --list -n" as one example.)

(I hope you are using secure telnet.)
