Dear. folks I want to shaping FTP traffic. I can get following information from Stef Coene's Homepage, www.docom.org. "Ftp uses random ports, so matching the data traffic is not easy. However it can done if you use iptables to mark ftp-data packets and use that mark with the fw filter. For more info see http://home.regit.org/connmark.html. " General information about the conntrack

Dear all, I''m reading codes in sch_sqf.c in kernel 2.4 of Linux. I find I messed up with the concept of slot, bucket and hash tables. Could anyone explain the data stucture of the hash tables a little to me. Thanks very much. Best, Franklin BTW: I can not understand why the number of entries of dep[SFQ_DEPTH*] should be twice:( _______________________________________________ LARTC

I''m not a programmer per se (including C), but... I''d like to be able to give the define in sch_sfq.c (of, say, 2.4.20), SFS_DEPTH other values than 128 as an argument on the tc commandline. It could be powers of two up to 2^7 (128) as it seems that 128 is the current maximum. I''m a little anxious to ask the question "How do I do that?" ;-) Instead

I''m grappling with a problem that looks like sfq is not working (packets don''t get fairly queued, they appear to be always sent FIFO). My configuration appears to be correct. The machine is running quite an old kernel and if I could convince myself that the sfq code it has is just broken, I''d spend the time to upgrade it. Is there any way to inspect or dump the sfq hash

Hello, I have one Q. What is better when using as leaf in one leaf with several hosts (like subnet) to splice traffic equaly to user number? Like 2 users = 256/2, 3 = 256/3 and so on. WRR was pretty good for this job, but it''s only for 2.4.21 kernels and mine''s 2.4.22. So what is better: SFQ or TBF? -- Artūras Šlajus _______________________________________________

Hello, Why linux users use SFQ as leaf queueing discipline instead of RED and other? -- Best Regards, S.Mehdi Sheikhalishahi, Bye.

Anyone notices that using sfq qdisc adds latency compared to pfifo? With "sfq perturb 10" ping latency is around 100-120ms, while with "pfifo limit 3" drops to ~10-30ms (qdiscs belong to htb class).

Can I attach a SFQ qdisc after a TBF qdisc?

Hello all, I have a few question regarding PRIO and what it is. Is it used to prioritize what classes get what? I read the how to but it isn''t exactly clear. Also about SFQ. Does this disciplines keep traffic within a queue fair? for example if I classify all http connections to 1:10 and I have packets in the queue and another person is also sending packets to the queue.

http://ds9a.nl/lartc/manpages I finished some more manpages, and improved others. New are tc-tbf.8, tc-sfq.8, tc-prio.8 and tc-red.8.

Hi, I have a 3Mbit (up,down) connection going through a Linux box (Debian 600mhz, 500mb ram) using NAT to approx 125 users. Presently I am shaping by marking packets by their port numbers. I''m prioritizing 22, 23, 25, 80, 81, 110, 443, 500, 3389, 1214, 6881:6889, etc, into their appropriate classes depending on weather there getting more or less bandwidth. This has worked pretty

Can I use the same SFQ queue dicipline for all the classe in a CBQ or HBT system?

Hello, I haven''t been keeping up with sending ESFQ [ANNOUNCE] messages to this list, but I''ve still been working on the patch.

I''d like to implement something like SFQ, but with a cap of a rate per flow. Essentially, I''d like to be able to limit citrix connections to 30KBps without having an overall traffic flow cap for all citrix connections. Slightly preferable to this would be something that would actually work per flow instead of the stochastic algorithm. Is this possible? Thanks, Bill --
