Other than bandwidthd. If anyone knows of a good, free, robust tool please let me know. Looking for some good functionality. I am surprised there are not more tools at source forge.
When it comes to bw management you are probably going to have a heck of a time finding something useful and full featured that is 100% free.. That said I would suggest the following products in order of least expensive to most: StarOS Router (http://www.star-os.com) Mikrotik Router (http://www.mikrotik.com) ETinc BWMGR (http://www.etinc.com) Mikrotik is cheap, like $45 StarOS is around $25 now I think ETinc is like $700 or so (for the license) Anyway, these are all license prices. You build the box. I prefer ETinc BWMGR myself and have used it for years. It is BSD and Linux capable, and EXTREMELY powerful. I still cannot figure out why anyone bought a packeteer with the bwmgr around.. Anyway.. good luck!
Ok, I was thinking you were looking for an actual bandwidth manager.. Duh.. Yeah, if you just want to graph/monitor bw, MRTG is the way to go. The tools I mentioned previously will do way more than what you may be looking for.
Yea, MRTG looks great but I wish there were some screenshots on there. Bandwidthd just seems too clunky.
Visit http://wispconvi.mia.net/ and download the our ppt on MRTG here:http://wispconv.mia.net/ppt/mrtg.ppt This should be a start anyway..
for free open source webbased bw manager try visit http://playground.bosen.net/DeoSHAPE/ not quite 100% finish though
