PFtop monitor



I just tossed together a quick top-like monitoring script for your pf
firewalls.  It displays the output of "pfctl -s info" at one second
intervals (by default).  It does not accept any user input... just
ctrl-C to quit.
Enjoy!

Usage:
pftop [delay in seconds]
Script:
#!/usr/bin/perl
my $delay = $ARGV[0];
$delay = int($delay) || 1;
while (1) {
        system("clear");
        print "PFtop v 1.0 - J.Dixon - 2002.11.16\n";
        system("pfctl -s info");
        sleep $delay;
}
