This is a multi-part message in MIME format. ------=_NextPart_000_002F_01C1D0D4.F4777C40 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Hello, thanks for the help I've received here, I think I've cracked my problem. I have a tiny (5MBit) satellite downlink to share between several thousand clients, and I wanted to give higher paying clients more speed. I tried WRR, but after three days meddling with kernels etc, gave up. The attached script uses CBQ to do the following: Create classes for various speeds (512Kbit -> 8Kbit), and assign IP addresses to each class Create a default class, limited to 2Mbit, which everyone else will share equally (SFQ) I've tested it quite a bit, and it seems to work. However, I really don't know the details of tc etc, so it's possible that this is total rubbish. If it is, could someone point this out? Also, does anyone know a good way of filtering by MAC address, rather than by IP address?
