RE: Port question

["Murda Mcloud" <murdamcloud () bigpond com>]

113 is an auth port for ident.

http://www.iana.org/assignments/port-numbers

And Steve's site:
http://www.grc.com/faq-shieldsup.htm#IDENT

The post is closed, which means that nothing can come through-unless first
initiated by something from inside your network.

Stealthing means that the scan coming from grc doesn't know what is at the
other end. Could be something, could be nothing. In the case of 113, though,
it knows 'something' is there and it's closed. Not sure how much can be
enumerated from that single port, however. Not much, except that a host is
there.

Not much to worry about, to be honest.

Google for stealthing 113 on smoothwall and see what comes up or check their
excellent forums.

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
