How to monitor network traffic from your keyboard

tleds, is a small tool to convert the keyboard leds in those of a network card, indicating through them the incoming traffic and the outgoing connection.

This feature is capable of modifying the use of the keyboard LEDs, making the Scroll-Lock LEDs work for the packets sent and Num-Lock for those received, in this way we will see if our network is working correctly even though it is not working. in graphics mode.


The Tleds tool is only available on systems that run with Debian, as well as on other Arch Linux systems, so to install it you must use the traditional method:

To install it on Debian , you must enter:

sudo apt-get install tleds

To install it using the traditional Arch Linux method, enter:

yaourt-S tleds

After this, the network mode should be taken by default, the incoming and outgoing traffic working. If the network has not been taken by default, it can be activated manually, taking into account whether it is ethx or wlanx (replacing "x" with the corresponding number).

In the case that it is ethx, you must enter:

sudo / usr / bin / tleds -q -c -d 25 ethx

In the case that you want to change to wlanx, you must first kill the process by entering:

sudo killall tleds

To get the system startup to run again, just add the previous line in /etc/rc.local.
