How to Install trafshow on Debian (netdiag Package)

Many system administrators use the trafshow utility to analyze network activity, in particular to quickly find out who is eating up the bandwidth.

I have written before about trafshow on FreeBSD; now it is Debian Linux’s turn

Those who rushed into battle with apt-get install trafshow were defeated, because at the time trafshow was not a separate package — it came inside a package with a set of utilities.

trafshow is part of the netdiag package

The command to install trafshow:

apt-get install netdiag

On current Debian releases first check whether there is a package of its own: apt search trafshow.

Other useful tools

You can also install iftop and nload, which are useful for watching who is talking to whom:
