Ok, I have this server script that I am currently writing for use with a gui front end. I am trying to do some simple auth with a user id and password, and for the most part it works just fine. Though I have come across a strang thing when sending a response back to the client. I am calling a sub that checks the id and password and returns the userid on good and undef on bad. The problem is that when I try to set the return to something the response never gets sent to the client. If I just call the sub by it's self everything works great .... any ideas Thanx

sub Sserv {
    my ($sever, $log, $logfile) = @_;
    $server = IO::Socket::INET->new(
            LocalPort => 3300,
            Type => SOCK_STREAM,
            Listen => 0,
            Reuse => 1,
            ) or die $!;

    open($log, ">> $logfile");
    select((select($log), $| = 1)[0]);

    while (my $conn = $server->accept) {
        my $t = threads->create("gClnt", $conn, $log, $server) or die 
+$!;
        $t->detach;
    }
}

sub gClnt {
    my ($conn, $log, $server) = @_;
    my $user;
    while (defined(my $ans = <$conn>)) {
        if (my $mess = chkAns($ans)) {
            if ($mess =~ /^LOGIN_REQ:.*/) {
                if ($user = userLogin($mess)) {
                    print $conn "GOOD";
                }
                else {
                    print $conn "BAD";
                }
            }
            if ($user) {
                print "$user:$mess\n";
                KILLER($conn, $log, $server) if $mess =~ /^END_PROC_RE
+Q:.*/;
                last if $mess =~ /^LOGOUT_REQ:.*/;
            }
            else { last; }
        }
    }
}

sub userLogin {
    my ($mess) = @_;
    if ($mess =~ m/^LOGIN_REQ:([\d \w]+):([\d \w]+)/) {
        tie(my %db, 'SDBM_File', $userDB, O_RDWR|O_CREAT, 0666) or die
+ "Problem accessing user DB\n";
        if (my $pass = $db{$1}) {
            my $pwd = PwdCrypt->new($2);
            if ($pwd->check($pass)) {
                return $1;
            }
        }
        untie %db;
    }
    return undef;
}
