Hi, After preparing my talk on CBQ/HTB (http://ds9a.nl/cbq-presentation ), I finally understood how CBQ and filters etc truly work. And I wrote it down. Check out the Linux Advanced Routing & Shaping HOWTO, it's changed a lot! Especially this part is very new, please check it for mistakes and inconsistencies: http://ds9a.nl/2.4Routing/HOWTO//cvs/2.4routing/output/2.4routing-9.html I even got 'split' and 'defmap' figured out, which should be a first. There is not a single other page online that tells you correctly what these do. One thing - does *anybody* understand how hash tables work in tc filter, and what they do? Furthermore, I could use some help with the tc filter police things. So if you do understand how these work, please drop me a line.
