First of all, i'm not the original poster but with the same problem. I'm trying to wrote a small script what does next things: Logs into router over telnet (that part works). Send command to the router and get the necessary date (also works). When i need some extra features to configure in router then a press a certain button, subroutine associated with the button does what it supposed to do and the that's basically it. What i'm trying to do is: Add a Button to the page and this button calls first subroutine. My first sub is sub telnet { logging into router only!}; When i press the button it should call sub called &telnet(); and after successful login it should call another sub what i define and all that should be working on the same page. Without sub pages on my site. Example part of the script that's working fine:

#!/usr/bin/perl -w 
print "Content-type: text/html\r\n\r\n"; 
use Net::Telnet (); 
use CGI qw (:standard);; 
my $user = 'username'; 
my $pass = 'password'; 
my $host = "192.168.1.254"; 
$t = new Net::Telnet (Timeout => 1, Prompt => '/\$ $/i'); 
$t->open($host); 
$t->waitfor('/: $/i'); 
$t->print($user); 
$t->waitfor('/ : $/i'); 
$t->print($pass); 
$t->waitfor('/>$/i'); 
@lines = $t->print ("system settime"); # it takes router uptime info 
($output) = $t->waitfor('/=>$/i'); 
print "<pre>"; #for nice output 
print $output; 
$t->print("exit"); 
print "</pre>"; #for nice output

This is all in one script to show you working part. I know how to make a sub but How to call it with the button. How to call several sub one after one just cliking the button. Second sub contains something like that:

@lines = $t->print ("turn off dhcp server"); #for example 
($output) = $t->waitfor('/=>$/i'); #waits prompt
print $output;

"turn off dhcp server" - whatever command i will wrote there. It's not a good idea to call all subroutines at once, one bye one. It's not necessary, could make something worse etc. To make this "page" more compact i would like to call those subs in the script itself with a button. Any hints, examples appreciated!
