Perl and listening TCP socket

Asked by salmjuh in Perl Programming Language

Tags: tcp, listening, only, socket

Hi gurus


I need to listen a TCP socket for a specifig string, take that string and make something with it.

So far I have no luck and here is my code:

----------------------  START ----------------------------
#!/usr/bin/perl -w
use IO::Socket::INET;
use LWP::UserAgent;
use IO::Socket;


# Open LOG file for debug
open (LOG,">>/tmp/log.txt");

#Open socket
$MySocket=new IO::Socket::INET->new(Listen  => 5,
                             LocalPort => 3319,
                               Proto => 'tcp') or die "$!" unless $sock;


# Next we need to wait so long, that we receive a string "PROG_ID xxxxxxx" ,where xxxx is a some ASCII string. Time to wait is from few seconds to 6 hours
while(1)
{
        $MySocket->recv($ID,512);
      print LOG "From socket $ID\n";       # Are we getting any

              if ($ID =~ /^PROG_ID/)
              {
                      print LOG "IF-LAUSEESSA: $ID\n";
                      $ID =~ s/PROGRAM_START //;      #RIP off "PROG_ID and leave only ASCII string
                  print LOG "ASCII ID is: $ID\n";

            }
}
