perl: Subroutine question
Hi everyone,
I have given up finally trying to find a way to do this.
I have a subroutine called LoginFirst where I am starting a new SSH session.
I have bunch of subroutines, each one of them uses a (or I have to create
a new SSH constructor everytime) ssh connection to get some value so
what I did is use LoginFirst to first start a ssh and then re-use the handle
in all other subroutines but does not seem to be working, can someone please help.

Code:
sub LoginFirst {
    my $ssh = Net::SSH::Expect->new (
           host => $self->{ipaddr},
           password=> $self->{Password},
           user => $self->{UserName},
           raw_pty => 1,
           timeout => 10
    );
  return $ssh;
}

sub DeviceVersion {
      my $newssh = LoginFirst();
      my @commands = ("enable","show version");
      my $commands = join "\n", @commands;
      my $prout = $newssh->exec($commands);
      print " $prout\n";
}

ssh-argv0

SSH-ARGV0(1)                                                BSD General Commands Manual                                               SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.  If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).
