It is used to rate limit a flow. e.g. if the incoming traffic is at 10Mbit, you could set up TBF to rate limit everything to 1Mbit by just a single line of config like the one given in the manual. Once you get that working, its acts as a sanity check for your setup and then you can start experimenting with the much much more complex cbq and its more accurate successor, HTB. > I found an installed cbq.init (a script to setup the tc commands for you), > but it does not appear to be working.

Any thoughts? I would advise you to just check the above TBF scenario first, and then move on to more complex ones like CBQ. Stef has some excellent documents on CBQ experiments (www.docum.org) and Devik is developing the excellent HTB (http://luxik.cdi.cz/~devik/qos/htb/) By the way, what traffic generation tool are you using? Or is this live traffic, which is usually a bad idea if you dont want extremely slow connections for some users ;) ciao, Amit p.s.
