There are times when one needs to know the traffic on a network to track down compromised users. It turns out our edge router for the TWR network in Galax is capable of providing the information required. 

I set up a packet sniffing streaming receiver here in Fairfax but Mikrotik is adequate for the task so I don't need to collect the information remotely.

I don't put on a stole when listening to confessions but I, like Shultz, know "Nothing!" Be assured that Big Brother has collected enough information upstream to reveal the most sordid details of your affairs.

The office in Independence is closed. All operations are now in Fairfax, VA. That means a lot of duplicate equipment. I plan on tailgating at Winterfest in Annandale on Sunday.

I recently upgraded my workstation monitor with a built-in camera and microphone. The entertainment machine has an external camera and microphone (Logitech, Inc. QuickCam IM/Connect).  Both have Google Voice installed and "Hangouts" appears in my tools menu. I normally have Gmail open when I am around, so invitations to video chat should get my attention. Gmail is probably the primary means of contact but a video call may be more effective for complex issues especially when screen sharing will demonstrate a particular problem.

The ground rules:

Ran a bunch of updates and trashed Also trashed my main workstation here in Fairfax. Chasing DDOS attacks on our wireless and fiber network. Needless to say, a bit much for this old sys admin.

Fortunately the fix for LS.Net was easy.

Fortunately I run a stock base so reinstalling the base seems to have fixed everything.

Hung port again on Cisco Router - Replaced

Comcast tech replaced the router with another Cisco 3939B. Woody checked out the connected devices. Everything looks good.

Helen, this server, went down again this morning. I bounced power to the server but that was not enough. Woody went to the POP and swapped ports with the Power Distribution Unit on the Cisco Gateway router and Helen came back. Bounced the Cisco router and after about 10 minutes everything came up. Waiting for a response from Comcast on the reliability issue.
