IMQ driver & kernel options
Hi,
i tried to insmod the imq.o module from http://pupa.da.ru/imq after a
successful compile, but it thows this error:
> insmod imq.o
imq.o: unresolved symbol nf_unregister_hook
imq.o: unresolved symbol nf_register_hook
I think I have some kernel options disabled, does anyone know which
one(s)?
Thanks
cord

Shaping traffic bound for the NAT''ed networks whithout imq
I''m trying to set up a shaper that can shape the inbound traffic to around
40 subnets, that hang on 3 different interfaces of the router.
As Linux can''t do ingress shaping I''m left with having to set up 3
seperate shapers, one for each internal interface.
This is not completely optimal as I''ll have to limit each of the 3
interfaces to 1/3 of the total

Htb, imq and sfq traffic shaping
Hello,
I wrote a simple traffic shaping script (below) that should have allowed me to shape my internet traffic a bit (ppp0 - adsl 128kbit/64kbit; local interface eth0).
The script works only partially - the speed is being limited but too much. Without running this script my download rate is about 10kBytes (with second computer also downloading at about 6kBytes). After running it my download speed

traffic shaping with NAT: IFB as IMQ replacement?
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

Ingress Shaping using IMQ
Hi Guys,
Here is a question that is probably of concern to many of us.
I am under pressure to provide some solution for ingress traffic
shaping. What my customer demands is to divide the downstream (ingress)
of an ADSL lines to two classes of traffic - important traffic and non
important downloads. He has a very reasonable requirement: he wants a
guarantee of at least 1000kbps at all times for

Q about "overlimit", and IMQ/NAT trick
hi,
I''ve successfully implemented shaping and policing with HTB for my
SDSL line.
Some tips&tricks I discovered which were not covered in the FAQs and
docs I read:
- To discover the appropriate rate for your line, flood it with
traffic and reduce the rate until the matching class starts to show
a consistent backlog -- only then you''ve managed to take the queue
away

IMQ problems :-(
Hi
I have built a custom TMB Mandrake kernel (2.4.22) with IMQ and ESFQ
support. I statically compiled both (mistake?) ESFQ is sorted and
working fine (I have succesfully patched IPROUTE2).
I have got to the stage where I can see the IMQ device as UP with ifconfig.
I can use TC to add QDISCs to the IMQ device. However I just cannot sort out
IPTABLES to actually redirect packets to the IMQ

HTB and IMQ and combining ingress/egress
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I''ve just discovered that trying to pass traffic from multiple interfaces
through the same imq is a Bad Thing(tm). A quick search of "HTB IMQ panic"
showed me older posts on this list saying that it''s simply incorrect to pass
such traffic through the same imq dev. I''m now back to square one on using

Little question about imq device
Witam
I''ve found many examples where packets are redirected to IMQ device
in PREROUTING chain for ingress traffic shaping purposes.
But is there any sense in redirecting packets to IMQ in FORWARD
chain also for ingress traffic shaping purposes?

what''s the meaning of xchg()?
lartc-request,hello!
I find a line in tbf_change() in sch_tbf.c: ptab = xchg(&q->P_tab, ptab);
Can I consider that the pointers are exchanged between q->P_tab and ptab? as following:
prev=q->R_tab;
q->R_tab = rtab;
rtab = prev;
Is my understanding righ?

imq or ingress+htb?
Todays quick question:
Ive had problems with imq and getting my setup to work as planned. Im
thinking that a better solution for shaping incoming traffic would be to
put a little limit in the outer interface of the router box with ingress,
and the shape traffic on the inner interface with htb. Would that be
better than using imq?

Shaping the sum of in/out traffic (IMQ?)
Hello,
does anyone have a working solution for the shaping both incoming and
outgoing traffic in such way, that for a given class the sum of incoming
and outgoing traffic is specified?
My ISP does the same thing, it gives me just a line of a defined rate,
no matter the traffic direction (i.e. here is the line, the clock speed
is 1024kbps, do what you want).
I''m a litte bit familiar

IMQ stability
Hi,
I''ve never actually even tried to use the IMQ device before,
but I''ve watched the emails go back and forth on various problems associated with it,
and what looks like some general instability.
How stable is it really ? Is it suitable for full-time use on a large number of
routers ?
Has anyone used it on ipsec0 + eth0 devices for shaping ?
and lastly, any difference

When i have inserted imq module ip_queue module insertion giving error

Failure seldom stops you. What stops you is the fear of failure.

Please help - totally confused (NAT + FWMARK + IMQ + HTB)
Hello,
I''m trying to get my shaper to work, but have only a partial success.
Can someone help me with that. My setup unfortunately is not so trivial,
but I think some people could have similar one...
1. There is a router connected to the internet line via interface eth0
2. There are users connected to the router via two interfaces : eth1 and
wlan0
3. All users are assigned private IP

Combining ingress and egress ( IMQ+HTB)
I am successfully running ingress (IMQ) and egress (HTB) shaping on a
bridge.
Is there any way to combine and share the bandwidth between ingress and
egress?
Example:
I have set up www service for egress at 128 KB and ingress at 256 KB. The
shaping on them works fine separately. However, I want to create a single
virtual pipe for www traffic and limit both ingress and egress combined to
256 KB.

IMQ strange problem
Hi All,
Please to advice me. I become crazy because i cannot find where can be
problem. Obviously i miss something, but what ?
I have Linux router for traffic control / ~400 users , 100 mbit bandwidth /

Problem that i have is when i start follow iptables rule
