Hi all,
I''m having a hell of a time getting my IFB to work. I know I''ve done
this before, so I''m missing something stupid. Can anybody tell me what
it might be?
Configs as follows:
--------
#!/bin/sh
modprobe ifb numifbs=1000
modprobe act_mirred
modprobe 8021q
brctl addbr br0
brctl setfd br0 0
brctl stp br0 off
brctl addif br0 eth1
brctl addif br0 eth2
ifconfig eth1

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

IFB & 802.1q
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).

Shorewall & IFB
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

Adding qdiscs crashes kernel??
Hi all,
I''m having some problems setting up qdiscs on a bridge.The config looks
a little like this:
ifconfig ifb0 up # Bring up the IFB for this bridge.
tc qdisc add dev eth2 ingress
tc qdisc add dev eth3 ingress
tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000
cell 8
# Raw qdiscs on each bridge port
tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

ifb and ppp
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

Re: Traffic not redirected to IFB - problem solved
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

complex; ifb, masq et omnia
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.

ipsec and ifb device
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.

RED to use ECN (or work at all?)
Dear Community,
sorry for the somewhat dumb question. Maybe someone has any pointer
to how to setup the RED queue to mark pakets with ECN. In particular
what are appropriate parameter settings for limit, min, max, etc.
All my trials end up with either "RTNETLINK answers: Invalid
argument", although the command line (at least for me) looks fine in
regard to what is said on the

Understanding IFB
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?

Little problem with ifb. How to catch server traffic on IFB...
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:

multiple IFBs
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.

Info about IFB
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

Inaccurate results without natting the traffic.
Hi folks.
For quite a while, I tried to use linux (cbq and htb) to control
bandwidth in order to replace a cisco equipment used to play this role
on our network.
After trying here and there, with a bunch of different distros,
different versions, different compilations, ... the closest I could
get was as follows:
(using htb.init and cbq.init)
Desired BW ==> Achieved BW
128k ==> 404.78
