it gets defined on exit from sub bind_socket, i.e.,

...
    my $server = IO::Socket::INET->new(
        Listen      => $self->{ListenQueue},
        Proto       => "tcp",
        Reuse       => 1,
        @address
    );

    $self->log( 0, "Can't bind to port $self->{GatewayPort}: $!.",
        "(Is another gateway already running?)" )
        unless $server;

    $self->log( 8, "Binding listener socket to ", $server->sockhost );

    return( $self->{ListenSocket} = $server );
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
}

Incidently, ListenQueue is set at 10 in NoCat.pm, and that is about as many connections as a 56MB access point should handle before
it gets clogged.


To quote Carla Schroder, http://www.enterprisenetworkingplanet.com/netos/article.php/3592556

" The purported 54 mbps of 802.11g is mythical; at best you'll get 48, which is nice, but most likely you'll get 20-30, and as nodes
are added it will probably drop all of them to 11 mbps. "

of particular note are two of her references at the end of this article:
