Re: [ANet-devel] Coding: What You Can Do

[Quentin S. <que...@co...>]

Hi-
There should also be a way to manually set your IP address. Here is some 
perl code that can find your outside IP if you are behind a firewall. I 
am behind a firewall, but I can set the firewall to route unidentified 
packets to my computer, so this is useful.

use LWP::Simple;
sub getIP() {
#www.dyndns.org = 207.127.235.88 as of 7/30/00
#$IPtxt = get("http://207.127.235.88:8245/cgi-bin/check_ip.cgi");
#Now using upsys.be:
#upsys.be = 213.61.13.10 as of 8/29/00
$IPtxt = get("http://ubsys.by/dyndns/check_ip.php3");

$IPtxt =~ /Address: ?([0-9.]*)/;
$ip = $1;
if (wantarray) {
$IPtxt =~ /Hostname: ([^\n]*)/;
$name = $1;
return ($ip, $name);
}

Please beware of line breaks from email.
