Re: detecting host with stateful firewall

[Matt Buttner <mbuttner () gmail com>]

Moreso if you know the mac address, get with your network guy and find
where the host is plugged into(assuming it is not a wireless client).
The MAC will be in the mac address table of the switch and the
associated port. If you only have the IP address you can arp for the
mac on the switch as well.

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
