similar to: How can I use different flows comming from ingress qdisc?

Hello, i''ve found this page (lartc currently down) http://www.lartc.org/howto/lartc.cookbook.synflood-protect.html where someone used iptables firewall mark to mark specific packets which will be shaped thru ingress qdisc with a fw filter and rate policy appended. I''ve tried similar this way, but it don''t work. Now i''m belief this could''nt work

Hi, all I''ve got problems with tc qdisc ingress. I''m using vanillia kernel 2.6.14.4 patched with http://www.ssi.bg/~ja/routes-2.6.14-12.diff, and iproute2-2.6.14-051107. i am using ingress to limit incoming traffic : (DEV is eth1 / DOWNLINK is 7700) # attach ingress policer: tc qdisc add dev $DEV handle ffff: ingress # filter *everything* to it (0.0.0.0/0), drop everything

Hi all I am attempting to police the incoming rate by using the ingress filter based on the TOS of the incoming packet. I used the following commands: tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 6 u32 match ip tos 0x10 0xff police rate 24kbit burst 1k drop flowid :1 On downloading a 6 Mb file which was TCP and TOS 0x10, this filter made on

Hello, I am using the following iptables POSTROUTING rule to NAT some RFC 1918 addresses: iptables -t nat -A POSTROUTING -s 192.168.19.23 ! 192.168.0.0/255.255.0.0 -p tcp --dport 80 -j SNAT --to-source 10.32.4.2 (I am using SNAT instead of MASQUERADE for performance reasons). I have several addresses on the 192.168.0.0/16 subnet that I am SNAT''ing similarly. Problem is, ''tc

Hi stef and all I want measure the policy perfomance for video traffic on mpls diffserv network. there are two different polices for video packet 1. Video packets that are marked that are over the limit are to be rejected at the edge router. 2. Video packets that are marked that are over the limit are to be downgraded as best effort and are sent through. Before video enter my mpls

I''m having trouble getting ingress policing to work on a bridged device. The bridge contains several interfaces: peth0, vif0.0, vif[1-7]0.1, vif[25].1 . (This is under xen, in case the vif''s didn''t give that away, so peth0 is renamed eth0.) The tc rules I have are: tc qdisc del dev peth0 root tc qdisc del dev peth0 ingress handle ffff: tc qdisc add dev peth0 root

Hello everybody on the list, I have the following situation where I want to police the speed of incoming packets from specific subnets to 1024kbps and then police all the rest to 256kbps, which is the speed my ISP grants for the rest of the internet. So, eth1 is the one connected to the cable modem and then to the internet. I do: tc qdisc add dev eth1 ingress handle ffff: then: tc filter

Hello, i try to limit the incoming traffic rate using the ingress qdisc, but it does not work for me. Here is what i have done: # sudo tc qdisc add dev eth1 ingress # tc filter add dev eth1 parent ffff:0 protocol ip prio 1 u32 match ip dst 172.17.0.101/32 police rate 10kbit buffer 10k drop The ingress qdisc is there: # tc -s qdisc show dev eth1 qdisc pfifo_fast 0: bands 3 priomap 1 2 2 2 1

Hi, So far, if have understand correctly: I route the incoming tcpip message of port 8099 directly to 8080 and then the ingress filter on port 8099 has nothing to do!? Yes I think on different interface on one machine (different Ports for different Request, with different restriction). What has exactly to be done to set the policier before Prerouting! Which kernel options, or also extra

Hi, I''m trying to police the incoming traffic by using ingress qdisc,this is what I have in my script tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 4 \ handle 1: u32 divisor 1 tc filter add dev eth0 parent ffff: protocol ip prio 4 u32 \ match ip dport 4001 0xffff \ police rate 2000kbit burst 50k drop \ flowid

Hi, Thanks for the fast response, .)Okay I tried your suggestion for my port 8099 and nothing happened: The tcp ip information goes from a firewall to my port 8099 and this port is than routed to the original 8080, I do that because I don`t want to dirturb my port 8080. But it seams the ingress filter doesn`t work on it!! iptables -L -t nat Chain PREROUTING (policy ACCEPT) target prot opt

Hi, I''m having issues with policing my incoming traffic by matching packet marks made by iptables. I''ve checked as many sites and guides as I can find, and I seem to be doing the exact same thing as they all are, but there''s still no success. As such, I was wondering if anyone can have a quick look to see if I''ve done anything obviously stupid? Essentially, I

Hi, My problem is following now: I would like to set the filters for port 8099. I have tried it, but nothing happened. When I try the same filter for the port 8080 it is working very well. .) working filter (here I can see the dropped packages): tc filter add dev eth0 parent ffff: protocol ip u32 match ip dport 8080 0xffff police rate 1kbit burst 1 drop flowid :1 .) not working filter (here I

Hi guys , i am starting to "play" with qos in linux. Well , i am trying to setup an ingress filter but i do not know why it is not working. tc add qdisc dev eth0 ingress tc filter add dev eth0 parent ffff: protocol ip prio 1 handle 1 fw police rate 160kbit burst 256kbit drop flowid :1 After that : iptables -A PREROUTING -t mangle --sport 80 -j MARK --set-mark 1 So , i think this

Hello list! In am stuck in getting the wondershaper script working. The last line of the script (tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match ip src 0.0.0.0/0 police rate 1800kbit burst 10k drop flowid :1) produces the following error: RTNETLINK answers: Invalid argument Could somebody please give me a hint on how to fix this? Regards, borghart

Hi all. Since I move on to 2.6 kernel , filter ingress policy based on nfmark won´t work. Sorry for my english. Simple example: iptables -t mangle -I PREROUTING -j MARK --set-mark 1 ${QDISC_ADD} handle ffff: ingress ${FILTER_ADD} parent ffff: protocol ip prio 100 handle 1 fw \ police rate 128Kbit burst 10k drop flowid 2:11 # tc -s -d qdisc ls dev eth0 qdisc ingress ffff: ----------------

Hi, what is needed to activate ingress policies for enterprise server 9! My current loaded modules: in the attachments my kernel: Linux linux 2.6.5-7.97-smp #1 SMP Fri Jul 2 14:21:59 UTC 2004 i686 i686 i386 GNU/Linux So you can see the module sch_ingress is loaded and also the package iprout2 is installed. I have set also a filter for ingress policies but i don`t think it is working,

Hi ! I wanted to shape my analog modem connection so I took these two lines from the ''wondershaper'' script: tc qdisc add dev $DEV handle ffff: ingress #tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip \ src 0.0.0.0/0 police rate ${DOWNLINK} burst 10k drop flowid :1 with DEV=ppp0 and DOWNLINK=24kbit. But, when I activate it, nothing comes back from the
