Measuring the consumption of bandwidth on your network in Linux

I'll show you two tools to check the network promptly to help us to make a measurement bandwidth consumption that is having to evaluate potential bottlenecks in the network.

OPTION 1: iftop

It's an interesting alternative for terminal, as always tested on Ubuntu Linux.
To install it enough just to make the classic:

# aptitude install iftop
The command has a few parameters to play with making a iftop man, will have a long list, but I'll show you some examples:

To see your network interface you can write:
$ ifconfig -a
To see what passes for the network interface wlan0 you need write:
# iftop -i wlan0
Scan IP range and interface wlan0:
# iftop -F 192.168.1.0/255.255.255.0 -i wlan0

If you press the h key when we are seeing the details gives us many more options.

OPTION 2: Iptraf

It's another alternative with a little more graphic and a small menu that meets their homework very well.
Installation is very simple:
# aptitude install iptraf
To run the program:

# iptraf

Averiguar tu IP pública desde la terminal

Hay una forma de averigar esa IP pública haciendo uso del comando curl. Si no tenéis instalado el paquete habrá que instalarlo, tal y como indican en ITswapshop, donde revelan el proceso tanto para Ubuntu:

sudo apt-get install curl

Como para openSUSE

sudo zypper install curl

El proceso de instalación es análogo en otras distribuciones, y una vez con curl instalado bastará con escribir en la terminal lo siguiente

curl ifconfig.me
