Does ssh timeout prevention help? What happens when you use Net::SSH2 to connect to the cisco unit?

I was just looking into something similar yesterday, in trying to figure out how to allow Net::SSH2's channel to start a background process on the target machine, without it dying when the ssh connection is dropped. See Re^7: A little demo for Net::SSH2.

What I noticed is that the c version of ssh2 has the ability to automatically put itself into the background and run commands as no_tty ( or something like that).

In other words, the c version detachs itself automatically, but a perl connection may need it done manually with

nohup perlprog.pl &
[download]

then close the console

I'm just trying to point out the detachment process, as a possible reason for the difference between the c ssh and the Perl version, and that maybe it is the cause of your problem.
