SSH2 Connection issue with Net::SSH:Perl

sparkyichi has asked for the wisdom of the Perl Monks concerning the following question:

For the Life of me I can not figure out why I can't get the following code to work. I know the destination is running ssh 2 and I can SSH to it.

#!/usr/bin/perl -w use Net::SSH::Perl; use strict; my (%params, $ssherr, $sshexit); $params{'protocol'} = '2'; $params{'port'} = '22'; $params{'debug'} = 'true'; $params{'interactive'} = 'true'; $params{'compression'} = 'false'; $params{'identity_files'} = [$ENV{HOME}."/.ssh/id_rsa"]; $params{'options'} = ["RSAAuthentication yes", "PasswordAuthentication no", "ConnectTimeout 10", "BatchMode no", "FallBackToRsh no", "RhostsAuthentication no", "RhostsRSAAuthentication no", "KeepAlive yes"]; my $sshconn = Net::SSH::Perl->new("secsscsr01", %params); $sshconn->login('user', 'password'); my ($out1, $err1, $exit2) = $sshconn->cmd("ls -l"); if ($out1){print "Output:\n$_\n\n";} if ($err1){print "Error:\n$_\n\n";} print "Exit Code:\n$exit2\n\n";

I get the following when it is executed:
comops:~/tkl # perl -w ./ comops: Reading configuration data /root/.ssh/config comops: Reading configuration data /etc/ssh_config comops: Allocated local port 1023. comops: Connecting to secsscsr01, port 22. comops: Remote protocol version 2.0, remote software version OpenSSH_3 +.6.1p2 comops: Net::SSH::Perl Version 1.25, protocol version 2.0. comops: No compat match: OpenSSH_3.6.1p2. comops: Connection established. comops: Sent key-exchange init (KEXINIT), wait response. comops: Algorithms, c->s: 3des-cbc hmac-sha1 zlib comops: Algorithms, s->c: 3des-cbc hmac-sha1 zlib comops: Entering Diffie-Hellman Group 1 key exchange. comops: Sent DH public key, waiting for reply.

    What is the machine you are trying to login to? I ran into this problem several months ago trying to use version 2 to login to a windows/cygwin host. I found dozens of references to people having similar problems with Net::SSH::perl and Windows together, but never did find a solution, I ended up solving it by using something other than ssh, which worked for my needs at the time...

    We're not surrounded, we're in a target-rich environment!
      I am trying to get it to work from Linux Suse9.1 (My Workstation) to AIX 5.1.

    Sparky did you ever make any advances on this problem? I am also stuck on this, regardless of what the host/client OS's are, it always ends up the same way....really really frustrating. Scott Hoover
      No, I decided to work on this later. I will probably find another method.

    Should cpanminus be part of the standard Perl release?
