Hi

I have a couple of daemons that listen on ssl sockets using IO::Socket::SSL. So they do their own listening and don't use (x)inetd. For this reason, they don't automatically inherit the benefits of tcpwrappers. I could do some filtering of my own fairly easily, but I wanted the transparency of doing it through hosts.deny and hosts.allow

I've read the page on Net::TCPwrappers and tried various things, most of which cause no errors, but none of which actually return a negative response from the call to hosts_access.

I suspect that the difficulty I am having is related to my lack of familiarity with the underlying TCPwrappers library and also trouble with marrying up the values from IO::Socket::SSL with the ones required by Net::TCPwrappers. For what it's worth, this is the code that currently isn't working:

 
my $sock;

    print "Starting to listen on $setup{CAPSportS}\n";
    if(!($sock = IO::Socket::SSL->new( Listen => 5,
                   LocalAddr => $setup{MYaddr},
                   LocalPort => $setup{CAPSportS},
                   Proto     => 'tcp',
                                   SSL_verify_mode => 0x01,
                                   SSL_cert_file => 'certs/capscert.pe
+m',
                                   SSL_key_file  => 'certs/capspk.pem'
+, 
                                   SSL_ca_file => 'certs/cacert.pem',
                   Reuse     => 1,
                 )) ) {
       print "unable to create socket: ", &IO::Socket::SSL::errstr, "\
+n";
       exit(0);

}

MAIN_LOOP:
while ( $TRUE ) {
    $nn = ''; 
    my $s;
     if ( ( $s = $sock->accept() ) ) {
        # check TCPWrappers to find out if we want to look at this
        my $req = request_init(RQ_DAEMON, $setup{CAPSport}, RQ_FILE, $
+sock->fileno());
        # I've tried supplying the progname instead of the
        # port there
        if ( ! defined($req) ) {
            die "Bad call to request_init\n";
        }
        fromhost($req);
        if ( hosts_access($req) ) {
           handle_one($s);
        }else {
        close($s);
        }

Looking around the interwebs I get the distinct feeling that I'm the only person standing in this particular room. Has anyone got some working perl that uses TCPwrappers that they could show me??
