[LARTC] HTB flooding my kernel logs
Hi I am trying to upgrade our systems with 2.4.20/HTB3 (before that I used 2.4.9 based kernel with HTB2 patch with no such problems). Since it booted the new kernel I get a lot of kernel messages that keeps klogd using CPU. Here is a sample: Jan 21 09:57:34 s kernel: KERNEL: assertion (cl cl-un.leaf.q-q.qlen) failed at sch_htb.c(959) Jan 21 09:58:05 s last message repeated 447911 times Jan 21 09:59:06 s last message repeated 879964 times Jan 21 10:00:07 s last message repeated 901413 times I can comment out that assertion from sources but what exactly does that warning mean ? Should I silently ignore it or do I need to fix it ? Also when I run our htb configuration script I get a lot of this kind of messages: Jan 21 09:50:15 s kernel: uantum of class 10056B is small.

Re[2]: [LARTC] u32: how to say all except z.x.y?
Hello Stef, How I can say all except z.x.y ? SC Use 2 filters : SC 1. all z.x.y to a class SC 2. all to an other class SC so the second filter matches all except x.y.z Ok. How it will be for ingress? It have only 1 class, haven't it? -- Best regards, Ray-Nger mailto:[EMAIL PROTECTED] ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Re: [LARTC] checksum update in TCP

Namely, is there a serial line (possibly wireless) involved? Yes it is. There is wireless net inbetween. But interestingly I have seen no other packet corruption except when communicating via FTP with concrete W2k user. He can FTP with others as I can too but can't between themselves. Also how could wireless link change data inside of a TCP packet ? Then checksum should become wrong and the packet rejected ... ? Yes, they should. What I had in mind was a data-dependent bug on a 2 Mbps wireless link that caused packets having alternate zero and one patterns in it (0x or 0x) to be dropped by the link and never seen by the receiver. Now, I'm not sure what the exact symptoms are of what you are solving. If your problem is that the TCP transmission completes successfully (i.e. everything's OK as far as TCP is concerned) but the data that came out of the pipe is different that the data that had been sent, that should be a different problem. I changed proftpd to compute and log MD5 of each chunk of data going out of read() syscall so I will be able to compare them to file on HDD (catching errors in FS, IDE (DMA) or HDD). Also in the same time I'll save tcpdump's raw packets to be able to compare stored data with packet contents (with 100MB ftp file it will be a lot of fun :-( ) Can you produce a binary diff of sent and received file to see how exactly they differ? Are the two files completely different? Or do they differ just in a couple of places? Is something missing? Is something changed? If so, how? That's how I managed to isolate some difficult data-dependent bugs, it might be useful here, too. pvl ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

So all packets matched by the 1. filter can pass thru and all packets matched by the 2. filter are rate limited.

[LARTC] tools for traffic monitoring
Hi all, are there any tools (besides ntop) which you guys use to monitor traffic, service by service? mrtg is not enough, I want something that can show me traffic on a service by service basis, and from/to which host. I guess ntop is quite complete in this area, but is there anything else? Thanks ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

What if you the iptables helper that can match packet with a string in it? I think the select is unique so you can see the difference. Once you can recognise the packets, you can mark them with iptables. That mark can be used to put the packets in differenct classes so you can configure different rates for the packets. But this will suck if you select statement is too big for one packet.

Ok,next was for classifying packet by making use of marking what if i m using u32 classifier instead of fw. is there utility with u32 tomark packets. also, what i think is that, classifiers will come into the picture after the connection establishment, so how could they differentiate 2 different type applications for same service? 10x in advance ganesh.
