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

Hi, I''m trying to activate IFB device support in a 2.6.17 kernel from Debian Sid. I read that IFB device is the replacement for IMQ device, but I haven''t found any useful documentantion on how to activate this feature and the kernel documentation lacks of this information. I remember that IMQ could be activated in the ''Network devices'' menu in 2.6.8 kernels,

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 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 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

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

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, 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

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

I have been looking at the hfsc for some time as a replacement or at a class that can be used like htb. But I seem to have run into a problem. With htb classes it is easy to make three or more levels of priority for a connection. All you need to do is to make classes and give them different prio levels. But it seems like you can only define a real-time bandwidth and a link sharing bandwidth.

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

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).

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

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay

I''ve network with NATed hosts. I want to catch only all traffic going from my server, but I don''t want catch NATed traffic from LAN. I need only traffic going from/to my server (traffic from INPUT, OUTPUT chain in iptables) (like SSH, postfix, WWW or proxy). This is throw all traffic from my LAN to IFB: $TC qdisc add dev $iface_lan handle ffff: ingress $TC qdisc add dev

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
