Actually I think I set it up at one point to admin more than one server. Just make sure server 2 allows connections from #1. (typically they'll only be setup to allow access from localhost)
Look in config.inc.php where it has something like:
Code:
$i++;
$cfg['Servers'][$i]['host'] = '';
$cfg['Servers'][$i]['port'] = '';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['controluser'] = '';
$cfg['Servers'][$i]['controlpass'] = '';
$cfg['Servers'][$i]['auth_type'] = 'config';
After the $i++ just plug in server 2's info. Then do the same for all your other servers as well.
