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

#debian #ubuntu #comandos
