Another SSH failure

Hi,

Mark Berryman reported that ...
The Multinet SSH2 client is unable to talk to any Cisco router. It is
able to successfully connect. It is even able to run non-interactive
commands. However, upon entering the first keystroke, it aborts with
Disconnected; protocol error (Received data for non-existent channel 0.).
Just this week I've seen the same thing here, trying to log in to a new
Cisco 877.
We have many SSH clients in use here and all others talk to the Cisco
routers just fine, including the TCPIP Services SSH client. This
problem only exists with the Multinet SSH2 client. The problem exists
SSH1 works, only SSH2 fails. However, by corporate fiat, I am limited
to SSH2.)
In my case I'm trying to use the MultiNet V5.1 SSH2 client. Here's a
sample:

Given the log I'd suggest adding /no_x11_forwaring to the command line.

Hi,
Post by Richard Whalen
Given the log I'd suggest adding /no_x11_forwaring to the command line.
I thought of that as soon as I sent my message ... but it made no difference.
