My first port of call tends to be tcpdump, with various filters and greps to pick out what I want. Usually I'm looking at RTP streams [0], so I run it through some perl to decode [1]

For wider monitoring, at key points on the network I use ntop [2] to see what's

If I want a quick overview of a given machine I load up iftop [3], which isn't very thrilling on my desktop at the moment

All of these are trivial to install (except for the RTP perl script which I have as a custom apt-gettable package) and don't require non-standard interpreters and package managers.

Nethertheless I went to get this. I had to install 540MB of support files just to run "go get github.com/gcla/termshark/cmd/termshark". Still it compliles. Then I run it, and it shows bugger all, I suspect I need to find and install more libraries (tcell, gowid), which themselves require massive downloads.

It's simply not worth it, it's like going back in time 20 years.
