Net::SSH::W32Perl - hanging

[seth]

Hi all:


I have the following environment:

Citrix session (windows 2000 I believe)
ActiveState perl 5.8.7
Remote machine (either AIX or Linux).
*the debug output included is for connection to the AIX box.

What I'm trying to do:
------------------------------------------------------
using Net::SSH::W32Perl to make a ssh connection (passwordless) and
execute a command like this: ls -l >> foo.txt


My problem:
------------------------------------------------------
The SSH session hangs.
This script works if it is not run in a citrix session. In other
words, it works fine in my
development environment which does not require me to use citrix.

The debug output shows that I connect, and the requested action is
carried out. It is closing the session, that doesn't work (my guess).



I think the problem *could* be citrix, but I'm just not sure.
I'd appreciate some feedback, as to what else I can try.
I'm wondering if anyone can give specific feedback as to what to try,
but looking at my debug output for the SSH
connection the script invokes.

thanks.

Here is the sample code that I'm running:
------------------------------------------------------

#!/usr/bin/perl

use strict;

use Net::SSH::W32Perl;
use Net::SSH:erl;

my $file = ".\\id_rsa";

my $user="mightybob";
my $host="server.company.com";

my $ssh = Net::SSH::W32Perl->new($host,
debug => 1,
protocol=>'2',
interactive=>0,
port=>'22',
identity_files=>["$file"],
use_pty=>1);



$ssh->login($user);

my ($stdout, $stderr, $exit) = $ssh->cmd('ls -l > foo.txt');

print "STDOUT: $stderr \t $exit\n";



Here is the debug output:
