It will be included in next kernel releases of course. Did this OOOPSes only affect 2.6 kernels or did (could) they occur on 2.4 as well? Thanks for the help...

[LARTC] Routing problems
Hi, I have some problems with my routing configuration. My router has two connections to the internet, eth1 (2Mbit) and ppp0 (ADSL). On the eth1 connection I do a snat and on ppp0 I do masquerading. I use iptables to mark packets / connections in the -t mangle -A PREROUTING and OUTPUT chains. The marks (1 and 2) are used to decide which route do use to route a packet. My routing configuration: #ip rule list 0: from all lookup local 32678: from all fwmark1 lookup EXT_2M_RT 32679: from all fwmark2 lookup EXT_DSL_RT 32680: from 80.129.94.144 lookup EXT_DSL_RT 32681: from 195.145.7.218 lookup EXT_2M_RT 32766: from all lookup main 32767: from all lookup default #ip route list 217.5.98.16 dev ppp0 proto kernel scope link src 80.129.94.144 195.145.7.216/29 dev eth1 proto kernel scope link src 195.145.7.218 172.25.0.0/16 dev eth0 proto kernel scope link src 172.25.0.1 127.0.0.0/8 via 127.0.0.1 dev lo scope link default via 195.145.7.217 dev eth1 #ip route list table EXT_DSL_RT 80.129.94.144 dev ppp0 scope link src 80.129.94.144 195.145.7.216/29 dev eth1 scope link src 195.145.7.218 172.25.0.0/16 dev eth0 scope link src 172.25.0.1 127.0.0.0/8 dev lo scope link src 127.0.0.1 default via 217.5.98.16 dev ppp0 src 80.129.94.144 #ip route list table EXT_2M_RT 80.129.94.144 dev ppp0 scope link src 80.129.94.144 195.145.7.216/29 dev eth1 scope link src 195.145.7.218 172.25.0.0/16 dev eth0 scope link src 172.25.0.1 127.0.0.0/8 dev lo scope link src 127.0.0.1 default via 195.145.7.217 dev eth1 src 195.145.7.218 For my routed packets, incoming on eth0, everything works fine, but for the packets generated by the router itself I have problems. For example I mark RSYNC packets, with mark 2, to use the DSL connection. The router sends out the packet over the DSL connection, but with the IP address of eth1? Somebody knows whats wrong?

[LARTC] Filter hashing
Hi, Anyone cares to explain how do the hash filters get calculated, cause I haven't understood those and I would really need a hand on that. For example, I want to build filters for two nets : 192.168.0.0/24 and 192.168.1.0/24. How do I do that ?

[LARTC] Graphing tc output
Hi, My HTB shaping is working perfectly, and i have setup a bridge and hosts behind the bridge are now getting only the bandwidth they are supposed to get. Thanks to every one here for helping me out :) Now I am thinking of making a graph of traffic going through various classes. Is their any thing readily available for it, or is parsing the output if tc and passing it to rrdtool the preferred way? Any suggestions?

[LARTC] traffic control using libpcap
Hi all, I have to use traffic control sending packets with libpcap. I'm using the following queues: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 1 tc class add dev eth0 parent 1: classid 1:1 htb rate 75kbps tc class add dev eth0 parent 1: classid 1:2 htb rate 50kbps tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip tos 0xA2 0xff classid 1:2 tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip tos 0xA8 0xff classid 1:1 If I test such system using udp traffic generator it works but when I send the packets using libpcap the filters don't work and all the traffic is queued via the default class (1:1). How can I fix such problem? Thanks Maurizio Paone ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
[LARTC] imq crashes again (new version)
Hi, I decided to continue imq development since it is not much usable as is now. I am going to make imq the only place for all trafic shaping. But there is one problem that this driver is very unstable by some reason it crashes randomly under high load when dropping many packets. and what is most strange that craches occur in kernel itself in tcp_retransmit_skb() function I suspect that it may be kernel bug. I didnt changed it very much, I just made that everything goes throuth imq device. so it needs to handle quite a lot trafic, seems the same problem have original driver if you set it to capture everything. Anyway this driver behaves strangely if you will check how many packets are dropped by htb you will see that none of them !!! they are just dealayed for extremely long time I suspect that such queue consumes too much memory or kernel is trying retransmit packets forever.
RE: [LARTC] Graphing tc output
Hi I use Stef Coene graphing tool see docum.org very good also check out bandwidthd @ sf.net, another nice tool that shows you bandwidth usage per ip. And to top it off, for your whole interface, plug in mrtg with rrd nice look Kalu Hi, My HTB shaping is working perfectly, and i have setup a bridge and hosts behind the bridge are now getting only the bandwidth they are supposed to get.

Re: [LARTC] Graphing tc output
Hi, I've recently written snmp extension to Net-SNMP package (www.net-snmp.net), where it's possible to get kernel statistics directly via snmp requests. But it's still beta quality :-( (known one memory leak, I'm going to look at it tommorow) If you are interested, I can put it somewhere... Michal Charvat Prokon R.B.S. Louny v.o.s.

Ok, I've put my code to: http://x-ray.prokon.cz/data/snmp.tgz It's quite simple, some code is copied from tc utility source... follow instructions in package and it should work...
