[plug] Debian: no telnet access after stable -> testing upgrade

[Denis Brown]

Thanks to Michael and Andrew...

Michael's point about open-ssh is a good one and I will in fact travel that 
pathway shortly.  I was attempting to get it to work in a plain-ish vanilla 
environment first.

Andrew... I have done the apt-get and inetd reload as you suggested, 
thanks, but the telnet session aborts before any signon messages appear in 
the telnet client screen.  I have seen that sort of behaviour before, when 
the forward and reverse dns info is incorrect so I will follow up on that 
aspect.  During the apt-get installation it removed the heimdal-servers, 
presumably because of a conflict with login.  Oh, "login" was the claimed 
latest version.

It may not be dns-related however, since attempting to telnet to itself 
from within an xterm window is also unsuccessful.  Telnetting to the dns 
name, the actual IP address or localhost in this manner simply returns 
"Escape character is blahblah" followed shortly thereafter by "Connection 
closed by foreign host".

Thankfully this is not a mission critical machine or situation so I can 
treat it as a good learning exercise :-)  A pointer to a good "read" would 
be appreciated.  I'll try the telnet-HOWTO if there is such a thing.

Cheers and thanks again.  Further suggestions gratefully accepted.
