Hi All,

I recently encountered some strangeness with establishing a telnet session
through a Nokia/FW-1 (FW-1 v4.1 SP2 on IPSO 3.2.1).

Packet traces showed that the FW was dropping the telnet commands from the
client to the server, so ECHO and GO AHEAD settings were failing to be
negotiated.

This resulted in the telnet session apparently hanging open on the client
side, but with nothing ever being displayed. Data was passed however, and
hitting return 3 times killed the session (as is standard for 3 bad passwds
at a Cicso login).

In this instance, the client was a W2k command-line telnet session and the
server was a Cisco Local Director.

A simple fwstop;fwstart fixed the problem, but I am concerned that it
apparently happened without cause and may happen again.

Has anyone else come across this before?

Thanks and regards,

Sam.
