We are going to see some of the network monitoring and network traffic related tools available in Debian

BWM - BandWidth Monitor

This is a very tiny bandwidth monitor (not X11). Can monitor up to 16 interfaces in the in the same time, and shows totals too.
Installing BWM in debian
#apt-get install bwm
This will complete the installation and if you want to see your network interfaces run the following command
#bwm
Output looks like below
Bandwidth Monitor 1.1.0
Iface RX(KB/sec) TX(KB/sec) Total(KB/sec)
lo 0.000 0.000 0.000
eth0 0.327 0.326 0.653
eth1 0.000 0.000 0.000
Total 0.327 0.326 0.653
Hit CTRL-C to end this madness.
If you want more options check bwm man page
Cutter - disconnect routed IP connections
Cutter will send packets to both ends of a tcp/ip connection to close the connection. It is designed to be used on a Linux router to disconnect unwanted connections.
