Subject: Monitoring bandwidth

Hi all,

Is there some code somewhere (library/script) that I can look at
that will help with the following:

I would like to monitor *all* traffic along the lines of
http://www.bwmonitor.com/ on whatever network(s) is/are active at the
time. Wireless and/or Ethernet.

Is there a way to monitor traffic in general moving across say wlan0
rather than specific protocols/ports (HTTP, FTP, etc)?

A Ruby solution would be good but Java/Python/Perl/ would be OK as well.

(The pipe dream was that I was going to try to write something like this
in all the languages above as a way to evaluate each of them).

(The even bigger pipe dream was that I could expand this to include a
GUI and make it into an open source project eventually. Pretty much
like 'Bandwidth Monitor' shown in the link above.)


thanks,
