| DNS Used to resolve hostnames to routable IP addresses. May also be abused as a conduit for unauthorized access through firewalls. Best practice is to determine your ISP's nameserver IP addresses and limit connections via this port as tightly as possible, rather than permit "any remote address". On a typical system, UDP to/from "any" local port to remote port 53 will be the only protocol required to be permitted for normal operation.

| Know Your DNS BIND is a server that allows remote users to turn network names into IP numbers.
eg) foo.mydomain.com => 10.0.0.1
I use BIND so that I may have a do-it-yourself domain. If you are also experimenting with hosting a domain yourself you will need BIND too. However BIND has many known security problems and is rather complex. It's important that you know what you are doing when you secure your name server. Here's a link to O'Reilly's book on bind.

|  Windows Explorer using DNS?
Every time I right click a file or folder it tries to go to what looks like my ISP (4.2.2.65:53) vnsc-lc-dsl.genuity.net
Can't find anything about this thru google. Anyone else having this problem? Spybot, Norton AV, ad-aware and Trojan Hunter all come up clean. | |

| Re: Windows Explorer using DNS? hey y'all
hopefully I'm asking this in the right place, but I think I have an issue with an outside force messing me up, in regards to my DNS lookup.
I downloaded and unzipped what turned out to be a very nasty file (or more specifically, many nasty files). My antivirus went off about seven times and I deleted countless files from '\Windows' and 'Temporary Internet Files' (not to mention figuring out how to lose the 'super hidden' files).
I downloaded this file about sixteen hours ago and in attempting to go back to the site and yell at the pin head who allowed it but am getting a 'Connection refused when ....".
The site was fine last night and I have tried with IE and Firefox, and also under a different user.
I can ping the site and contact it with 'tracert' but can't open the web page.
What else could it have done to my machine?
Oh ya, I cleaned out all I could find with 'Hijackthis' | |
