Gauntlet is equipped with something like Klaxon(hi Doug!) which lets you
know when someone 'touches' a port that doesn't have anything running on
it--this way you can tell if you're being port scanned.

In this case, if you're not running identd, then Gauntlet will let you
know that someone tried to connect to your auth port.  No big deal.

Use grep -v?

You might want to add the following to your netperm:

*: permit-hosts (internal network) -policy inside
*: deny-hosts (external network) -policy outside

Let me know if that does it.

Odd way of parsing the netperm table.
