pktstat displays real-time list of active connections seen on a network interface, and how much bandwidth is being used by anything. Partially decodes HTTP and FTP protocols to show what filename is being transferred. X11 application names are also displayed. Entries hang around on the screen for a few seconds so you can see what just happened.

4. CBM ( http://www.isotton.com/software/unix/cbm/ )
CBM is the color bandwidth meter. CBM is a small program to display the current traffic flowing through your network devices.

5. iftop ( PDW http://www.ex-parrot.com/ ~ / iftop / )
Displays bandwidth usage on an interface. He watched the traffic on the network interface and displays a table named the bandwidth used.
iftop is a tool to monitor your bandwidth with an interactive console.

6. Speedometer ( http://excess.org/speedometer/ )
To monitor network traffic or speed / file transfer process. Measure and display the data in the network connection or data stored in the file.
