[SLL] telnet localhost

[Bill Boulton]

Has anyone got any bright ideas about a computer's ability to telnet or
ftp localhost. I have two boxes, each with Slackware, connected as an
intranet.  Box A can successfully ping Box B but cannot telnet or ftp Box
B. Box B can ping, telnet or ftp Box A, but cannot telnet or ftp itself
(localhost). The /etc/hosts file in Box B contains the IP address of
localhost (127.0.0.1)  as well as the IP addresses of Box A and Box B.
I believe that if Box B could telnet localhost, Box A could telnet Box
B.  I'm stuck, can anyone help?
