[olug] Active bandwidth monitoring

[Michael Peterson]

I have a modified source version of bwm you can run on Linux as long as you
can compile it or have a binary compatible runtime for C programs from
another distro.
I have a shell script I run through cron that sends the data logged to an
HTML page so you can view it from anywhere you can access the server and if
you have apache running or another web server to serve the pages on the
Linux gateway/firewall system.

Here is a sample from one of my systems as of today.
You will notice that the RX and TX max change during today.
I rebooted the system today, so the program was restarted and the max RX and
TX are only stored in the program and not externally.
But the log file retains the info until you flush it or create a rotation
scheme for it.

This is based on an open source bwm program I found but did not get me the
results I thought that is should.

Most older stuff would only have 10mbit capabilities anyway, so if you want 
Cox's 12mbit stuff, you'd need a new modem just to get past that ethernet 
limitation.

What residential ISP guarantees a speed? Last I checked, they were all "up
to"
