Strange, the connection seems to be established correctly even when the authentication fails.

Enable debugging also for the ssh binary:

$Net::OpenSSH::debug = -1; $ssh = Net::OpenSSH->new( $device, user => $sshuser, passwd => $sshpwd, ctl_dir => "/tmp/ssh.$$", master_opts => [-o => "StrictHostKeyChecking=no", '-vvv'], timeout => 90, kill_ssh_on_timeout => 1, strict_mode => 0 ); print STDERR "ssh error: " . $ssh->error . "\n";

      The remote server is accepting your user/password pair as valid!

      You are probably talking to a miss-implemented or miss-configured SSH server. Try asking your administrator or the provider of the box.

      Try also, connecting from the command line adding the -vvv flags to the ssh command. What do you get?

        hi - thanks!!

        cmd line with debug results in:
        debug1: Authentication succeeded (password).
        debug1: Entering interactive session.

        and hangs 'till I kill it...

        mean while I tried to reduce ssh timeout to 15 seconds
        => I can trap almost all of the cases now, but (grrrrr) sometimes the boxes don't wait for the minute and I'm back to the beginning.

        no chance to work on the boxes for me...

        Any idea how I can catch that issue within my program??

        please...
        :-)

        and what's the meaning of that "-x2MN"?

        thanks a lot for your help
