Hi, I wanted to implement some QOS on my Linux Box with HTB, but after some time spend on the configuration and tests, I still don''t manage to have some correct results. Here are the details : -ROOT 2000 kbits -HIGHPRIO SUBCLASS 50 kbits prio 0 -SUBCLASS1 750 kbits prio 1 -SERVICE1 250 kbits prio 1

I am investigating changing our broadband bandwidth control scripts over to HFSC. What I would like to accomplish is this: { * DOWNLOAD * I need a download class for each user (we''ll call it Class 1) that offers a minimum of lets say 384Kbps and a maximum of 1.5Mbps. The rates between 384Kbps and 1.5Mbps should be shared among all users. Each user should always be able to get at

Hi all :) If I set the burst/cburst parameter to, let''s say, 1500, the command "tc -s -d class show dev eth0" says that the value is 1499b/8 instead of the (correct?) 1500b/8.

Hi all. I''m going on my 3rd week trying to get a simple traffic shapping to work the right way :( !! My goal it to shape the traffic coming from one machine (pc1) to another machine (pc2) throught the "eth0" interface.

...all, I''ve tried to look for this info in previous messages but had no luck. I''ve a 2.4.20 kernel on an Intel arch., all TC is configured and it seems to work. Anyway, I''ve had some troubles in configuring TBF via tc: 1. when I configure burst or minburst to be, say, 1500b, when I peek the configuration with "tc -s qdisc" the answer is that burst/minburst is equal to 1499. Moreover, any other value I try to configure in "b" unit is always decremented by 1 (3000->2999, and so on). Any clue about that? 2. I also have some strange behaviours abou...
