Piece o' cake. What you want to do is use a local script to telnet to host1, then from that host telnet to host2, and capture command output, right?

Simply create a telnet object, establishing a connection to host1, print a telnet command to host2 via that object, then tell the object to login again, this time with host2's settings.

I tested this with Net::Telnet, but I suspect it would work with ::Cisco as well. You might also add code to logout gracefully.

#!/perl -w

use strict;
use Net::Telnet;

# Cavaets:
#
# 1. This simple example assumes that the login, password, and command
# prompts are all able to be matched by the Net::Telnet defaults - if
# not, you'll need to add the appropriate parameters to the login()
# command when logging in to host2.
#
# 2. I'm not sure $! is going to be meaningful in my die() statements,
# but what the heck - insert your own debugging if it's not working.
# :-)

# First host
my $host1 = 'hostname1';
my $user1 = 'user1';
my $pass1 = 'password1';
# Second host
my $host2 = 'hostname2';
my $user2 = 'user2';
my $pass2 = 'password2';

my $session = new Net::Telnet (host => $host1)
    or die "Couldn't create: $!";

$session->login($user1, $pass1) or die "Couldn't login to $host1: $!";

$session->print("telnet $host2") or die "Couldn't telnet to $host2: $!
+";

$session->login($user2, $pass2) or die "Couldn't login to $host2: $!";

# Obviously, put your own commands in here - $session is now talking
# to host2 via host1.
my @output = $session->cmd('uptime') or die "Couldn't run command: $!"
+;

print "@output";

exit;
