NumLock and ScrollLock Keyboard LEDs will Indicate Network Traffic - Ubuntu

NumLock & ScrollLock LEDs help in Network monitoring

Some people rejoice themselves while working in Computers by Monitoring the Traffic Networks. Also this is useful for those users who have limited usage of data. Here a very innovative & interesting way is revealed to monitor the network from the keyboard itself. NumLock & ScrollLock LEDs flash to indicate incoming & out going network traffic on a wired or wireless network connection. 

Here we need to install a utility named "tleds", a network traffic monitoring utility. This is useful for users who want to monitor heir download / upload network activity.

Install through the terminal , simply run

•  sudo apt-get install tleds

To see your network interfaces, run this command

• cat /proc/net/dev

Start tleds with this command for a wired connection(You can also replace eth0 with your own network interface ( eth1, eth2, etc.):

• sudo /usr/bin/tleds -q -c -d 20 eth0

Also you can add a wireless connection(WiFi), follow this command:(Replace wlan0 with your own wireless network interface (wlan1, wlan2, etc.)

• sudo /usr/bin/tleds -q -c -d 20 wlan0

Your NumLock and ScrollLock LEDs will start now to blink indicating outgoing and incoming network traffic on the selected network interface.
