Hi, I was using ckermit as the telnet client, with a symbolic link from /usr/local/bin/telnet to /usr/bin/kermit

Alternatively, simply run kermit and at the C-Kermit prompt enter:

telnet localhost 

If using telnet from package telnet-ssl, one can connect using:

telnet 127.0.0.1 

(provided you are not doing so as root). 

Hope this helps, 

Arthur.
