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;

package mship;

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