Hi

I'm using this sip scanner

I want to make it take ips form a text file not to give it an ip range

i want to put a list of ips in text file

Like :

 ip-list.txt
127.0.0.1
127.0.0.2
127.0.0.3
[download]

this is the code

use IP_iterator;

$udp_maxlength = 100000;

$lport = $rport = $ARGV[1];        # default ports
$delay = 1;
