I see that I can disable ident (113) thru my linksys router AFTER connecting to IRC (on DALnet anyway) and the port is stealthed according to dslreports and grc.com. This only takes a few seconds to disable thru the browser and it's more secure.
That's true...but if you use IRC quite a bit....that's not a real feasible thing to do. Maybe, a firewall (software...cheap and easy, or even as firewall appliance, not so cheap, but very secure!), and only allow you're IRC client access to the port...that will certainly cut down on any threat!
Yea, I'm behind a linux firewall, anyone try Smoothwall? nice if you have a old box with some network cards in it, I use it to forward ports, like the TCP port 113, to a machine on my internal LAN, or whatever port I want to use that day.
On several security scans TCP Port 113 and UDP Port 113 were detected as OPEN. I am using a Linksys router and Kerio firewall with PPPoE DSL. In my router configuration, I managed to STEALTH TCP Port 113 by using UPnP and forwarding to a non existent IP address on my network. This technique does not work with the UDP Port 113, only the TCP Port. Can anybody advise me?
