Hi fellows: Im wondering about compiling cls_u32 sch_htb and bridge into the kernel Are there any advantages or disadvantages doing this in terms of stability or crash problems?

...n, howto or command''s help provides. I''ve been looking for information about the uses of ''offset'' parameter, or more detailed explanation of a few other/relevan options, but what I''ve found is very brief to say the least. So I checked the sources of cls_u32.c and f_u32.c. According to that, the separate ''offset'' parameter controls the offset to the subheader (i.e. tcp from the beginning of ip), and it must be supplied explicitely. So for example, doing something like: tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \ ma...

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

Hi. I can''t find any documentation on the specific selectors for tc-filters -- what documentation I have says they are in Polish in a file called selectors.html -- is there anything around in English to see those? Thanks. -- Your life is like a penny. You''re going to lose it. The question is: How do you spend it? John Covici covici@ccs.covici.com

Hello Everyone, I have this weird problem. I have 2.6.10-rc2-mm3 kernel with u32 compiled as module. I have the cls_u32 module loaded. I have different binaryes of tc, the one from iproute packaged from debian sarge, the Kaber''s one from trash.net, and also from another computer where u32 worked. When I run this: cyclops:~# /usr/local/sbin/tc filter add dev eth0 parent 6: protocol ip prio 4 u32 match ip sr...

Hi, I discover recently that the arp traffic is managed like any other flow. So you get hang after a moment if you don''t use a default class. Is the any means to avoid this ? Not to have a default class is a way to filter traffic ... One would be to managed to class ARP request with tc but I don''t know if it is possible. Thanks in advance, -- Éric Leblond courriel :
