[squid-users] Squid checking if AV is installed

Hi,

I'm working on a project to only allow users with updated AntiVirus
software to access Internet. The first step in this project is to only
verify if the AV is installed. To complete this stage I've adapted the
script listed below to check if the AV is listening in the specified
port (17217):

#!/usr/bin/perl
use IO::Socket;
my $VERSION = '1.0';
my ( $peer, $port );

# Disable output buffering
$|=1;

##look for server argument or display usage
#( $peer = $ARGV[0] ) || &usage;
#( $peer = $ARGV[0] );
$peer = $_;
##attempt to connect to all ports in hash index, then display open ports
$port = "17217";
$sock = IO::Socket::INET->new("$peer:17217");
if ($sock){
        print "OK\n";
}
else {
print "Err\n";
}

In squid.conf I've put some lines to use an external acl and to deny
access to non-compliant users.

external_acl_type AV children=100 %SRC /usr/local/squid/etc/checa_av.pl

acl AV_ACCESS external AV
http_access allow AV_ACCESS

When I reconfigure Squid I got the following errors in cache.log until
Squid crashes

 helperHandleRead: unexpected read from AV #1, 57 bytes
2005/07/07 18:50:10| helperHandleRead: unexpected read from AV #2, 57

2005/07/07 18:50:10| helperHandleRead: unexpected read from AV #7, 57

...

Is there a problem with "my" script or the configuration in squid.conf?
Thanks for help.
