Console bandwidth monitor

[paket]

Hello all.

I have gotten my Linux-based Internet gateway/firewall up and running and I thought "Wouldn't it be cool to have a traffic graph on this this?" The obvious answer is "yes", but this is an old 486 with limited disk space, so X is out of the question. Does anyone know of a traffic grapher proggie that outputs in text mode?

thanks

You might want to check out MRTG at mrtg.org. It outputs data to an html file that you could easily parse for five minute traffic average. You could also run tcpdump and watch the packets scroll past You could actually pipe the output of tcpdump through a perl script to count packets and such. I don't know of anything off hand though that outputs continuous data similar to "top" which I'm guessing is what you want.
