Hi monks,

I need to receive SNMP traps using a daemon and log it in a file. Can someone give me sample codes for daemonizing the program. I tried using Proc::Daemon but was unsuccessful. I am new to Perl. 

#!/usr/local/bin/perl

use strict;
use Carp;
use Proc::Daemon;
use SNMP_Session "0.60";
use BER;
use Socket;

Proc::Daemon::Init;

$session = SNMPv1_Session->open_trap_session (  );
   
while (($trap, $sender, $sender_port) = $session->receive_trap (  )) {
    chomp ($DATE=`/bin/date \'+%a %b %e %T\'`);
    #    print STDERR "$DATE - " . inet_ntoa($sender) . " - port: $sen
+der_port\n";
    print_trap ($session, $trap);
}


sub print_trap ($$) {
    ($this, $trap) = @_;
    ($community, $ent, $agent, $gen, $spec, $dt, @bindings) = $this->d
+ecode_trap_request ($trap);
    open(OUT, ">>output.txt")  or die "Failed to open file";
    print OUT "   Community:\t".$community."\n";
    print OUT "   Enterprise:\t".BER::pretty_oid ($ent)."\n";
    print OUT "   Agent addr:\t".inet_ntoa ($agent)."\n";
    print OUT "   Generic ID:\t$gen\n";
    print OUT "   Specific ID:\t$spec\n";
    print OUT "   Uptime:\t".BER::pretty_uptime_value ($dt)."\n";
    $prefix = "   bindings:\t";
   
    foreach $encoded_pair (@bindings) {
        ($oid, $value) = decode_by_template ($encoded_pair, "%{%O%@");
        #next unless defined $oid;
        print OUT $prefix.BER::pretty_oid ($oid)." => ".pretty_print (
+$value)."\n";
        $prefix = "  ";
    }
    close (OUT)
}

1;
