I tampered with a few console programs during my hiatus, with one of the more interesting being darkstat.
I don’t know if I should really call darkstat a console program or not. For what I saw, there was very little that it did at the console, with most of the attention going to its web-style output.
That’s very convenient if you just want to find out — graphically — how things are going, network-wise. Most of its configuration is at the prompt though, which you adjust when you start it.
But it runs light, as you can see, and I had no problem checking the traffic on the loopback address. I didn’t try it across the network, but I have a feeling it would probably be equally easy … so long as you’re properly configured, of course.
Believe it or not, that’s about all I have to say about it. I am debating internally whether I should add this to the wiki, since it seems to fall into a … gray area. Ha! That was almost a pun!😯🙄
