jnettop

Jnettop allows administrators of routers to watch online traffic coming across the network in a fashion similar to the way top displays statistics about processes. It is useful for quickly evaluating the state of the network.

            Great!
            I run a 10mbit download server using Linux traffic shaping and I couldn't find any way to see how the bandwidth was being shared out to my users, and whether or not people were getting good download speed when my line is maxed out. This tool is exactly what I was looking for and more. :) I was amazed to see it even shows which files they are downloading over HTTP!

            Current and future release
            I am currently using version 0.9 and it is a great help for identifying the bandwidth hogs. I would suggest a couple of features to consider for the future:

            1. Ability to set a threshhold and time after which an email alert is sent identifying the hosts and bandwidth used.

            2. Ability to do SAMBA NetBIOS lookups to get host names of the machines (this helps where the users are DHCP addressed.)

            3. Possible export to ipaudit, ntop, cricket/mrtg; this could even be just a command line option that tells jnettop to printf rows of comma delimited text instead of using curses (you could then use your own scripts to process the data.)

            Thanks for writing such a useful tool, and I hope you might consider the above suggestions...
