tor as an...availability service?

Posted 07-24-2013 at 06:26 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

Last night my wife complained to me that facebook was taking forever to load. I figured it was just a hiccup somewhere between facebook and our home network, so I waited a bit to see.

An hour or so later, she was getting impatient, so I fired up a tcpdump session on the firewall and watched her desktop exchange a pretty funny set of packets (well, you had to be there, I suppose), loaded with PUSH, URG, and FIN packets back and forth between her desktop and facebook. I laughed and...

So, one of my big fears on my home network is a virus outbreak. Granted, my wife is an incredibly paranoid web surfer, and in the 12 years we've been together there has been just one virus issue (and that was after our niece used her computer to surf some "ooh, I'm a vampire...I sparkle!" type of social sites).

Create vent user. Untar...
