I scarfed the Tk code Im presenting here from Re: Tk perl much thanks to Jouke.

My question is though, how to make the nodes appear in realtime as they are processing instead of all at once when they are done. This particular code is being run on a w2k workstation, if that matters.

the code

use strict;
use mship;
use Tk;

my $host;
$|++;

#First create a new mainwindow
my $mainwindow = new Tk::MainWindow();

#Then create a textwidget (called 'Scrolled', with subtype 'Text")
my $text = $mainwindow->Scrolled("Text", -scrollbars => 'se')->pack(-e
+xpand => 1, -fill => 'both');

for ( 0 .. 54 )
{ 
    get($_);
    last if ($_ == 53 )
}


# create a closebutton
my $button = $mainwindow->Button(-text => "close", -command => sub {$m
+ainwindow->destroy()})->pack();

# start the main loop!
MainLoop;
sub get
{
    my $node = shift;
    $host = sprintf ("%02d", $node) ;
    my %status = mship::connection("192.9.210.1$host", "13");
    my $stats=($status{status} == 0) ? "Up" : "Down";
    $text->insert('end', "$status{remote_name} is $stats\n");
}

the code for mship.pm is here

use strict;
use warnings;

package mship;

use IO::Socket::INET;
use Socket;
use Carp;
=head1 NAME

mship - The mothership connection or 
        how I learned to stop worrying 
        and trust the script.

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
