similar to: IFB support in 2.6.17 kernel

Hello, Sorry for the many Ccs, but I hope to reach all parties involved. I want to do traffic shaping with NAT and I wanted to do it with IFB instead of IMQ [1]. I tried a lot of things but now I am stuck (and maybe confused). The setup: eth0 eth1 WAN/(Internet) <-> Linux Router <-> LAN Linux router: - does NAT for the LANs - runs local processes

Hello I''m trying to switch from IMQ to IFB but I have a problem with traffic marked by ipp2p module. Looks like when traffic is redirected from ethX to ifbX it looses information about MARK. Here''s what I do to get ingress traffic to go to ifb interface: $TC qdisc add dev eth1.42 ingress $TC filter add dev eth1.42 parent ffff: protocol ip prio 10 u32 \ match u32 0 0

Is IFB realy replacement of IMQ Please Guide -- Failure seldom stops you. What stops you is the fear of failure. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hello! My goal is to setup an ingress traffic shaping on my PPPOE DSL line with ifb. My old imq stuff used iptables marks (like ''iptables -t mangle -A PREROUTING -p tcp --sport 22 -m length --length :500 -j MARK --set-mark 31'') to classify the traffic and since i am lazy, i tried to to reuse them with ifb. But no luck: iptables marks the packets well, but tc

How to use IFB as replacement of IMQ There is not much documentation about it Please explain with example -- Failure seldom stops you.

Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

Hello What I''m looking for is how to configure the Linux QoS module to do global rate limitation for two (or more) 802.1q pseudo network devices. I naturally suppose there is a possibility with IFB. I don''t want to use IMQ because it''s not integrated to my kernel v2.6.21.1 and I didn''t find IMQ patches for it nor for the iptables package I use (v1.3.7).

Hi all. I''m using Jamal''s ifb virtual interface from new kernel. Redirecting incoming traffic from external interface like that: # tc [blahbla] match u32 0 0 flowid 1:0 action mirred egress redirect dev ifb0 to ifb to shape it. The problem is that I''m using MASQUERADE by netfilter also. That redirected traffic coming from internet gets to ifb _before_ DNAT is done.

Hello Tom, Sorry, please but i again return to IFB question. If i correct understand in current situation IFB haven't profit from ESFQ in common cases (i mean internal networks masquarading) so as we wait from ESFQ allocates bandwidth fairly per source IP(internal) but IFB don't know internal IPs. If i correct, what do you think what can help IFB to solve its main disadvantage

Hey folks, I stumbled across the Mastershaper project ( http://www.mastershaper.org/ ) but I have a little problem: I wanted to shape the traffic coming from the router itself aswell as coming from the LAN behind the router, for that task I need IMQ, but with IMQ iptables-(layer7)-matching is not possible. Now I''ve talked with the programmer and he said the following: >The problem is

Hello, I want to use IFB instead of imq, but i don''t know how to redirect traffic from eth2.101 to ifb0 and traffic from eth1.301 to ifb1 so I can applied QoS. With IMQ i use iptables -j IMQ --to-dev 0. Is it possible to apply tc rules on ifb1 both download/upload ? thx _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Hello Tom! After i read and analyze some docs about IFB i decide that for implement this feature in Shorewall not need more efforts (of course i may be wrong). If we have 'ifb0' device then we must activate ingress discipline on real device (f.e. eth2) and redirect 'egress' from it to 'ifb0'. tc qdisc add dev eth2 ingress tc filter add dev eth2 parent ffff: protocol ip

Hello, It seems on RHEL/CentOS 5.2 iproute package is version 2.6.18, which apparently do not support IFB properly. The end result is that while no error is given, counters on ifb0 do not update, and capturing on the interface turns out nothing. Simply replacing tc with one from 2.6.26 solves this issue, it seems... Best regards -- Haim Gelfenbeyn Hagel Technologies Ltd.

I''m experiencing a problem with masquerade downloads saturating my internet connection. I''ve implemented an IFB and now am looking into flow keys. Although I''ve read the documentation, I''m not sure I have this right. Can someone help? /etc/shorewall/params: MID_IF=eth0 MID_IF_TC=1 INET1_IF=eth1 INET1_IF_TC=2 INET1_IFB_IF=ifb0 INET1_IFB_TC=3 Note: MID_IF

I''ve made some tests... eth2 is my internal interface, LAN is connected here. Before I had IMQ device in AB mode... PREROUTING [A]fter NAT, POSTROUTING [B]efore NAT. I want the same situation on ifb. I do this in this way: --- # incoming traffic here from LAN is before NAT tc qdisc add dev eth2 handle ffff: ingress # outcoming traffic here from WAN is after NAT tc qdisc add dev eth2

Hi everybody. I would like to know how incoming ipsec packets (from eth0 for example) interact with ifb device. For example: I want to redirect all incoming packets from eth0 to ifb0 for shaping. What happens to esp and the relative clear packets? By default both are seeing on the incoming device.

hello, i have eth0 (Internet) + eth1,eth2 (local), how to i use IFB in real for shaping Download, how to i redirect traffic from eth0 to ifb0 with "mark". I testing marking with iptables but any mark not working - always use "default" mark... thanks _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Hi all, Further to my previous questions, I need lots of IFBs on this thing. I have configured IFB as a module, and issuing a modprobe ifb loads it, but only gives me 2 IFBs (ifb0 and ifb1). How can I get more? I''m probably looking at needing about 20 on this project. Regards, Leigh Leigh Sharpe Network Systems Engineer Pacific Wireless Ph +61 3 9584 8966 Mob 0408 009

I''m trying to set up a traffic control on ingress attaching a egress qdisc to the ifb device. The idea is to use a RED algorithm instead of policing the incoming traffic. After trying with tc-red and not obtaining the expected results, I decided to try with something easier, and use htb as bottleneck: ifconfig ifb0 up tc qdisc del dev $dev ingress tc qdisc del dev ifb0 root tc qdisc add
