Hi there! Some questions I couldn''t find an answer for: IPtables: - Is it possible to filter those ACK-packets (to eleminate problems with ADSL-connections) with IPtables? It wasn''t possible with IPchains, so u32 had to be used. Now there is this nice little --tcp-flags option. But I just don''t know if this is all I need. The u32 was checking for packetsize too. So if

Hi If I use sfq qdisc on a CBQ class I get a lot of dropped packets and the backlog itr almost always to its full value: 128. From the HOWTO I understand that the queue is at 128 packets, and SFQ shows 128/1024 flows , but how can I increase that value ? I have tried ip link set txqueuelen but this only increases the tx queue on the interface. qdisc sfq d468: quantum 1514b limit 128p flows

The limit parameter for SFQ qdiscs isn''t listed in the howto. Based on a mail from this list from 4 may 2002 ("SFQ queue lengths - generalization"), I''d guess it limits the number of packets/bytes in in the queue, but wether it does so by number of bytes, packets, or time spent in the queue I don''t know. Perhaps someone in the know could add a line to the

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

Hi again, I was just looking around for ESFQ sources, and I see that the main site is down, and only has kernel 2.6.4 patches. Is ESFQ maintained? If so, where can I find patches for 2.6.10?

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, I haven''t been keeping up with sending ESFQ [ANNOUNCE] messages to this list, but I''ve still been working on the patch. If you''re curious about recent changes, take a look at the home page, ChangeLog, and README: http://fatooh.org/esfq-2.6/ http://fatooh.org/esfq-2.6/current/ChangeLog http://fatooh.org/esfq-2.6/current/README Meanwhile, I''m interested

Hi If I have a HTB class with 128kbit, and I want to put "N" users in that class ( in order to share bandwidth fairly ) , which is better for me ? esfq (hash dst) or wrr ? I would attach esfq or wrr to HTB parent class. Also I''ve readed on Jim script that over WRR put a RED qdisc, but I don''t understand it. bests andres

Hi there, i am trying to shape a network for a college dorms... INTERNET---- ETH0--------Nat Box-------ETH1--------LAN I have set up classes of traffic (HTTP, FTP, MAIL, IM, OTHER) and i have assigned a rate for everyone with a HTB qdisc. The limit based in traffic is working flawlessly. However, under every HTB class i have set up a ESFQ queue discipline with hash value set to

Hello! I am using since yesterday ESFQ instead of N HTB queues. It mostly works OK, but when somebody is using one single sesion (for example downloading file via FTP), it gets weird speed. For example it is 20 kilobytes pres second, then drops down to 9, then 20 again, and then slowly to 0 and stops. But when using download accelererator of some kind or bittorrent client which uses many

Hi I have a small lan (10.0.0.0/8) behind my linux box. I use MASQUERADE to allow users connects to internet. I set up an esfq qdisc for outgoing traffic. And there is a little question. Does source hash type in esfq recognize NATed local ip''s? -- Pozdrawiam Marcin mailto:slacklist@op.pl _______________________________________________ LARTC mailing

http://fatooh.org/esfq-2.6/ http://fatooh.org/esfq-2.6/esfq-2.6.12-rc1.tar.gz This version no longer interferes with the original SFQ; unlike previous versions, you can still use an unpatched tc with SFQ. Patching tc is still needed for ESFQ, though. I''ve tested this patch with Linux 2.6.11 as well. Please tell me if you have any problems. I''m subscribed to lartc again. -Corey

Hey folks, I stumbled across the Mastershaper project ( http://www.mastershaper.org/ ) but I have a little problem: I wanted to shape the traffic coming from the router itself aswell as coming from the LAN behind the router, for that task I need IMQ, but with IMQ iptables-(layer7)-matching is not possible. Now I''ve talked with the programmer and he said the following: >The problem is

Hello guys I have a subnet with 255 users, which need to share 1 single slow internet connection, so i would like to implement a kind of *fair queuing *on the UPLOAD between them, which means that they all share the connection equally.. The tools that i have available is: A linux box with IPROUTE2,HTB and TC.. I have looked at some examples, and my first idea was to make 255 entries in

What''s wrong... I have Celeron 633MHz nd 768Mb RAM. When I''m running my script everything is OK, but when I''m connecting Internet and LAN link computer is hanging. But when i dissconnect this everything is OK. I have 500 users, 1500 classes and 3000 filters. Is it normal? What should I do?

ESFQ''s original hashing algorithm never worked particularly well for the src or dst hash types: close IP addresses, such as 10.0.0.1 and 10.0.0.2 often hashed to the same number, even with many different perturbation values. This prevented the src and dst hash types from working adequately with small and medium-sized network ranges. A while ago, I added the src_direct and dst_direct hash
