Ok. Fully admit, old unofficial sysadmin here (50, started with computers at 10 - and I don't work as a sysadmin, but often wind up helping our sysadmin who has less experience). ifconfig, netstat, lsof are some of my top go to tools. I haven't learned the iproute suite of tools yet, but this article is prompting me to start doing that. It will be hard, my memory is fuzzy on when net-tools commands first came out..I remember using Slackware in mid 90s, but don't remember if they were in there yet, but I think I've maybe been using them for 20 years, or close to it.
