Wow, over a month since lab 4? I’ve been slacking.
No, that’s not actually true. A week off of work to prep a newly-purchased RV kept me busy. Then life, work, and sickness all occupied my time. I finally got back at it this week only to find this lab to be the most challenging so far, but in a good way.
In this lab, the theme was around sequence/acknowledgment numbers. They’re quite fascinating, as they’re essentially the bread crumb trail you can follow in a TCP stream. I had to pause mid week and go do a bit of reading on the topic so I could understand for myself what these values meant.
By the end of the lab I felt I had a grasp on the situation…and then I tried to analyze a simple packet capture. There’s more work on my part to do in this space, which will probably be done in the next few days. I’d like to fully understand this before I move on.
So back to the books – more tinkering and learning to do…
