When I run a connection test on google.com telnet to port 80, I get the following:
Fri Jul 30 2010 12:13:25 GMT-0500 (Central Daylight Time) Fri Jul 30 12:13:24 CDT 2010 - Test Successful! DNS fwd/rev mismatch: google.com != iw-in-f104.1e100.net DNS fwd/rev mismatch: google.com != iw-in-f106.1e100.net DNS fwd/rev mismatch: google.com != iw-in-f105.1e100.net DNS fwd/rev mismatch: google.com != iw-in-f147.1e100.net DNS fwd/rev mismatch: google.com != iw-in-f99.1e100.net DNS fwd/rev mismatch: google.com != iw-in-f103.1e100.net google.com [74.125.95.104] 80 (www) open Is this normal? I am connecting to the internet just fine during this test. Last edited by wtangle; 07-30-2010 at 11:18 AM.. |

What the... no that isn't normal. And it looks to me like your DNS has been hijacked...

you can connect via telnet but you can't open google.com in a browser?

Dirk, this is acting like my unit...
It randomly loses the ability to setup a TCP session for HTTP only and only does so for about 30 seconds. But in my case my box is overloading CPU because of a pile of spam landing on my door thanks to this stupidly fast DOCSIS 3.0 connection. With no mail server on site, either we have a large service that is over loading the box. Or, more likely, that high reputation workstation has a torrent hound on it burning up TCP sessions. I can't think of anything else that can be causing this.

Sorry, I forgot to mention that when I did the telnet connection test, I still was able to access any website from the browser. I have just never tried to do the telnet test when I lost browsing capability in the past (yesterday was most recent from my computer).
Another thing is that when this happens (cannot access google.com either from browser during this time), other computers on the same network are still able to surf the Internet just fine. This issue is very random, and at times end users don't call me, they opt to restart the computer and go on with their work. |

Clean that box and see if the problem goes away. One good torrent hound can do this by itself.
