Hi I am encountering what I suspect to be a bug in the kernel processing of tc netlink messages: I am using kernel version 2.4.9 with iproute2-current-001007 package. Everything works fine in the kernel. Now I open a netlink socket with a user process, read the tc netlink messages generated by the tc process and parse them. What I see is that the kernel has already processed the messages

Hi folks I have created a script file (dsmark+policing.sh attached) to check graphic an text outputs of simutations, against original examples/dsmark+policing coding (see TCNG Reference Manual-pg.90). It uses tcng coding (*.tcsim file attached) and old tc coding (*.tcsim_old file attached) inserted in tcsim files. Observation 1: The graphic outputs from (*.tc included in *.tcsim) and (*.tc_old

Hi, I am trying to get assured forwarding/expedited forwarding with gred and htb working. Below is the script I am using. The following steps are what I thing is how the script works. My problem is that if I remove the HTB qdisc from the script and have the GREDS parent as the dsmark it works, but when I add the htb as a parent of GRED and DSmark the parent of htb it does not work? Any

I want to set the DSCP field of the incoming packets. And then put them in the correct queues. I can mark the packets: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle 1:0 dsmark indices 64 set_tc_index tc class change dev eth0 classid 1:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent 1:1 protocol ip prio 1 handle 1 fw

All: I am tasked with creating an environment in which DiffServ and IP precedence is handled as close to RFC specification as possible. I have a few problems with implementing this based on current queueing structure. Here are a few of my questions. 1.) Is there any way to get DiffServ AF drop levels without using DSMARK and GRED? Ex. AF11 Gred DP 1 AF12 Gred DP 2 AF13 Gred DP 3 2.)

Im experimenting with using a Linux machine with 3 interfaces to operate as a core router. All links and network interfaces are 100mbit. Below is a ascii diagram of the network. (network A) edge router ------>core router---->edge router (network C) ^ | | edge router (network B) I have tried two

Hi, I want to setup core routers to do both DSCP marking and to get the DSCP and forward packets based on DS field. I don''t want to separate DSCP marking to be done only at the edge routers. I know that dsmark is both used for DSCP marking and for getting the DSCP and forwarding packets according to DSCPs. In my case, since I want to do both of these I need two dsmarks.(?) I am not

Hi all, Supposedly my router is itself streaming traffic to clients. Is it possible for it to mark its packets before going through dsmark?? I have gone through the examples in iproute2/examples, i noticed that there''s always an ingress and egress of which these are 2 different dev. Is it possible for before ingress and egress be the same dev?? I tried the script below but

hi all, i''m having problems building a module from my tcng configuration file. could someone verify the syntax for building a kernel module? i did it as shown below ... module gets built but i cannot load it. thanks charles ps -- sorry, don''t know c++ :-) [root]# cat /etc/tcng.test #define LAN "eth0" #define LAN_INGRESS 750000 #define LAN_EGRESS 750000 dev

hi all i am a new commer of linux community. i want to how does skb->tcindex value change exactly. it confused me indeed. i have a script reads: (1) tc qdisc add dev eth0 root handle 1:0 dsmark indices 64 default_index 0x161 set_tc_index (2) tc filter add dev eth0 parent 1:0 protocol all prio 1 tcindex mask 0xfc shift 2 pass_on (3) tc filter add dev eth0 parent 1:0 prio 1 handle 0x0a

Hello, I have the following proplem. My DiffServ configuration is working fine when I do ping, but when I use mgen the packets are not detected at the core router.

Hi i have configured my server with cbq and gred. The problem is that the cbq doesnt drop packets.

Hello all. We have three tunnels over the internet between our "central" gateway and some branch office gateway. Each gateway has eth0 on its LAN an eth1 on the internet. We use DSL lines and eth1''s have the internet IP directly attached on it. Each gateway, also, acts as iptables NAT gateway. The outgoing bandwith is 300 kbit, and we tried this (i.e.) on each tunnel: tc

Hello all, Please could someone help me with this, I have been trying for days to get this to work. I would like to have BE, AF & EF classes with HTB qdisc. I can''t find any scripts online where this has been done. If I enable this filter: #tc filter add dev eth0 parent 2:0 protocol ip prio 1 \ #tcindex mask 0xf0 shift 4 pass_on then BE & AF classification seems to be fine but

Greetings all, OK - just started playing around with traffic shaping - have imq and htb and (I think) everything else I need in the kernel and running well. My initial lab task was to protect a H.323 session over a simulated half T1 while adding bulk traffic - got that accomplished after slogging through learning tc and decided in short order that a more intuitive interface would be

Hello. I have been trying to duplicate these u32 matching rules using TCNG, but without much success: tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32\ match ip protocol 6 0xff \ match u8 0x05 0x0f at 0 \ match u16 0x0000 0xffc0 at 2 \ match u8 0x10 0xff at 33 \ flowid 1:10 Wondershaper 1.1a implements this and if I run it things seem to be shaped as expected. But this TCNG

Is there anyway to actually see packet stats or that packets are for sure going into a prio queue with TC? I can see all the HTB stats but the prio classes just list as being there...would like more information Basically I have the following setup DSMARK | HTB - (tcindex filter on TOS) | Prio (u32 filter on TOS) Thanks Jon Flechsenhaar Boeing WNW Team Network Services

Hello, its me again, I won''t stop sending emails to this list, until I solve this problem, I''ve tried several apps to create the right htb rules (even made them my self), but I always get the same results, traffic gets shaped, but I can''t use my bandwidth, and this is weird, because I should be able to, also I keep seeing download being limited too, and that
