I have a very straight forward script using Net::SSH::Perl that connects to multiple hosts and pulls data from them. The powers that be have added some new servers, and for some reason, the module will not connect to these new servers.

Here is a short version of what is failing: 
#!/usr/bin/perl -w

use strict;
use Net::SSH::Perl;
my $user = "username";
my $pass = "password";
my $domain = ".mydomain.com";
my $ssh;
my $host;
my @hosts = qw(host1 host2);

my $lscmd = "ls -ltr";

foreach $host (@hosts){
 print "$host\n";
        $ssh = Net::SSH::Perl->new("$host$domain", protocol => 2, inte
+ractive => 0, options => [ "Password Authentication yes" ], (debug=>'
+true'));

        $ssh->login($user, $pass);
        my ($lsout, $lserr, $lsexit) = $ssh->cmd($lscmd);
 print "lsout = $lsout\n";
 print "lserr = $lserr\n";
 print "lsexit = $lsexit\n";
}

host1 connects and displays lscmd fine. It is a linux server running OpenSSH_3.6.1p2

host2 is a linux server running OpenSSH_4.2. SSH debug info from the script shows:

I have tried with and without options =>, and both protocol 1 and 2.

I have added the following to ~/.ssh/config PreferredAuthentications password,keyboard-interactive,publickey,hostbased

The error stays the same using the script no matter which of the above I have tried

A manual ssh to host2 works, and using interactive => 1 works (although I have to type pw, which defeats the purpose since I have 200+ systems the real script queries)

I mention SSH versions above because that is the one difference I can think of that would affect this.

Does anyone know why this would fail, and what I can do to fix this?

Thank you in advance for your time
