I do computer stuff. When I solve a problem and it's not obvious, I document it here - it's a reference for myself, and hopefully, it can save other people out there days of problem solving, googling and assorted hair-tearing.

tcpdump example
Between uses, I generally forget how to do this.
tcpdump -i vr0 udp port 500 and host foo.example.com
-i to select the network interface udp port 500 is kinda self-explanatory host foo.example.com - just traffic where foo.example.com is dst or src
