Hey again, Trevor, [ cut ] : Thanks for the prompt reply. Am indeed glad that htb scales to my : enterprise requirements. I have performed tests on my Athlon 1.7Ghz but : still use my dell latitude for r and d. I also changed a bit my testbed, just to overclock the CPU to 863MHz (though it is the same Duron@xxx) and to add some 256MB of RAM, which totals 512. [ cut ] : I have tested the same time and again and am convinced this issue needs : to be clarified on. Obviously, and you'll see I'm backing you later on. : * Uptill 2000 U32 Filters and htb classes everything is fine : * Above 2000....i am very clear that probably htb classes formation : happens seamlessly but U32 filters stat throwing some stupid errors. In my test, tc started throwing errors at u32 filter, attached to classid 2048 tc filter add dev eth0 parent 1:0 protocol ip u32 match ip dst \ 192.168.20.48/32 classid 1:2048 RTNETLINK answers: File exists I'm not sure if htb classids (or better u32 classids) are limited to 2048 (dec), which equals 800(hex). I'm sorry, but I can't read sources, otherwise I could peek into Martin Devera's work to search for an answer. : * "RTNETLINK answers: No such file or directory" thrown up for filters : greater than 2000. Not exactly sure on which number...but very surely : above 2000. In my case, tc answered "RTNETLINK answers: File exists" after adding u32 classifier to classid 2048. This is probably not the case, because in my production setup, I have classids much higher than 2048, e.g.: tc class add dev eth0 parent $HOME64_CLASS classid 1:14116 htb \ rate $HOME64_CHILD ceil $HOME64_SPEED burst 12k quantum 1514 tc filter add dev eth0 protocol ip parent 1:0 prio $HOME64_PRIO u32 \ match ip dst 10.10.8.79 flowid 1:14116 tc qdisc add dev eth0 parent 1:14116 handle 14116: sfq quantum 1514b perturb 10 here HOME64_CHILD, HOME64_SPEED and HOME64_PRIO are variables, taking part in the script. : Any idea on whats wrong with my setup. Does this necessitate change in : use of U32 filters. Can this be avoided???. Or am i on the wrong : track???. Keeping in mind I wrote the above, I notice that I'm using a bit different sintax, i.e. attaching u32 classifiers to "flowid", not to "classid", as in your setup. But nevertheless, the resulst is a RTNETLINK answers: File exists : Any pointers towards resolving the same will be appreciated. Am : attaching the 4000 approx user script along. Personally I can't help, obviously. Am I missing something? I tend to be erroneous, but this is beyound the scope of my knowledge. ;) Martin Devera? Stef Coene? Martin Brown? Leonardo Baliache? Well, If I missed someone more deep-in-this-stuff, please, excuse me, but I would also be very interested in clarifying this. -- _____________________________________________________________ So long, and thanks for all the fish.
