[squid-users] external_acl_type not working

Hi

Is it possible external_acl_type isn't working in Squid 2.5?
I've added the following lines to squid.conf:
external_acl_type room_external %SRC /usr/local/nms/nmsdeamon2
acl room external room_external
http_access allow room

Heres my little perl-program. I know the code isn't good but it should work:
#! /usr/bin/perl

sub catch_zap;

$workdir = "/usr/local/nms";
@list;
catch_zap;

$SIG{ALRM} = \&catch_zap ;
alarm 5;

while ( 1 == 1 )
    {
    $input = <STDIN> ;
    open (FILE, ">> /output");
    print FILE $input ;
    close FILE;
    @temp = split( /\./, $input);
    $input = $temp[0].'.'.$temp[1].'.'.$temp[2].'.0' ;
    $found = 0;
    open (FILE, ">> /output");
    print FILE $input ;
    close FILE;
    foreach $ip ( @list )
        {
        if ( "$ip" == "$input" )
            {
            $found = 1;
            }
        }
    if ( $found == 1 )
        {
        print "OK\n";
        }
    else
        {
        print "ERR\n";
        }
    $found = 0;
    }

sub catch_zap
    {
    alarm 5;
    foreach $ip ( @list )
        {
        $ip = "";
        }
    open (FILE, "< $workdir/roomaccess");
    @list = <FILE>;
    close FILE;
    }

I've added some lines to get debiug-infmormation in /output
The Problem is the CLient-Adress is not send to my program.
Squids only sends "\n".

What's wrong?
