How to display network traffic in the terminal?

Question:

how to display the actual network traffic (wireless) in a terminal?

Additionally: Is it possible to add this info to the chart of top?

Solution:

It’s quite easy! install “iftop” with:

sudo apt-get install iftop

Then run

sudo iftop

from any terminal!

Enjoy!

There is a nice tool called speedometer that displays a graph in the terminal using Unicode block characters, colors, and even adds labels to each peak in the graph.

$ sudo apt-get install speedometer
$ speedometer -l  -r wlan0 -t wlan0 -m $(( 1024 * 1024 * 3 / 2 ))

It has several options, can monitor multiple interfaces, can show multiple graphs in several rows or columns, and can even monitor the download speed of a single file (by watching the file size on disk).
