life# reload

December 12, 2011

If you’ve been reading Evil Routers for a while, you already know that, back in May, I quit my job. The idea was that, after I took care of some things here, I’d eventually move to the west coast. Basically, that never happened. I got lazy over the summer and did absolutely nothing that I [...]

Why Gigamon Scares The Crap Out of Me

October 31, 2011

Choose Internetworking

October 27, 2011

Choose no sleep, lots of caffeine and no time off. Choose no friends. Choose black clothing and long hair. Choose tons of mail and wondering why the fuck [...]

Why You Should Be Blogging

October 20, 2011

As a network engineer, systems administrator, or just a general IT guy (or girl), you probably don’t think of yourself as a “brand”. You probably just think of yourself as an average person who happens to have a fairly marketable skill. Each of us, however, are our own unique “brand” and blogging can help you [...]

iou2net.pl, an IOUlive replacement

September 22, 2011

In the months since Cisco IOU leaked out, many people have began using it for study purposes instead of or in addition to dynamips. One advantage that dynamips has over IOU is the ability to communicate with a physical network which comes in handy sometimes, like when you want to do pointless things like dumping [...]
