[Ssh-sftp-perl-users] ssh session blocked after "cmd" with Net::SSH::W32Perl

[Philippe L. <phi...@as...>]

Hi,

I am much frustrated because near the success.. :)
I am trying to run ssh commands from a win 2k host to an Unix ssh 
server, using Net::SSH::W32Perl (0.06) from active PERL.
The connection and the authentication are speed, but after the command 
ssh->cmd, the ssh seems frozen, and the PC's CPU is growing up to 100%.
Then, nothing happens (during hours...).

My (simple) script is below :
#================ SCRIPT BEGINNING ==========
use Net::SSH::W32Perl;
use strict;
my $host="supervision";
my $user = "netadmin";
my $pass="XXXXX";

my %ssh_arguments = (debug=>1);
my $ssh = new Net::SSH::W32Perl($host, %ssh_arguments );
print "Step 1 \n\n";
$ssh->login($user,$pass);
print "Step 2 \n\n";
my ($out, $err, $exit) = $ssh->cmd('hostname ; exit ');
print "Step 3 \n\n";
print "Output = $out \n","Error = $err \n","Exit = $exit \n";
#================ SCRIPT END ==========


My output log is :


#================ LOG BEGINNING ==========

#================ LOG END ==========

Each time, the ssh is blocked at the same step : " 
input_channel_request: rtype exit-status reply 0".
I have tried with an other ssh server, but the behavior is the same.
I think I have installed all the modules required.

Many thanks & kind regards
