Now it’s my daily driver for work and home and with that I’m learning a lot and since you can use a lot of the applications in conjunction with each other with piping and what not.

TSHOOT – Linux Networking Style
When I got restarted in networking circa 2018-19 everyone on my timeline would always profess how much they loved Cisco’s TSHOOT exam. People had tickets to do and felt like they were showing off what they knew, their experience, rather than answering trivia questions. “I always recert my CCNP with the TSHOOT exam…” or soContinue reading “TSHOOT – Linux Networking Style”
zeek-cut vs jq
Last week I wrote a quick little tutorial so that one could get started using tshark. In this post I want to look at different ways of viewing the same data using a tool called zeek. Zeek is often referred to as a packet examination ‘framework’ as it allows you to see what is happening,Continue reading “zeek-cut vs jq”

OSPF Route Optimization – Multi-Area OSPF (Post 3)
In this post of the OSPF Route Optimization series, we take a look at multi-area OSPF. As stated before, while single-area OSPF provides us with global IP reachability, it tends to not scale well from an efficiency standpoint as the network grows. In our sample topology, we will treat the “inside” zone of each siteContinue reading “OSPF Route Optimization – Multi-Area OSPF (Post 3)”
scapy or not, here I come!
I came across a pretty cool tool during the first part of section 3 of my SANS503 course: Scapy. Using this tool you can do many things, for example, read in packets, edit packets and create entirely new packets just to name a few. The easiest way to get started it to just type outContinue reading “scapy or not, here I come!”
