Hi Everyone,
I am trying to write a perl code to access and run few commands on a
Secure CLI-Box using SSH module in Perl.After installing the Perl
module with a lot of difficulty I am facing the following issue. I am
able to log-into the box but I don't get any results back for the
commands I am trying to run on the box.
If I use the same perl code to log-into another linux machine and do
an"ls" I get the result back with no problems at all. Here is the debug
message while trying to access the CLI-box and running the commands.
Any Help will be really appreciated. I have been struck at the same
issue for about a month and my code is due soon and I have no clue how
to fix it.
