WonderShaper on LAN link kills to-host speed
I tried installing the WonderShaper on my internal link, mostly to get the
SFQ installed. I set uplink and downlink to 100000 to match the link speed
and changed the bandwidth on the cbq line to 100mbit. This killed transfer
speed *to* the box, knocking it from 30-40 Mbps down to about 800 kbps.
Commenting out just the ingress control restored the speed.
What about the ingress policer would do

port forwarding
is there anybody who can tell me how to forward request to other host, i
would like to forward all dns requests to other dns server and it must be
done with packet forwarding because dns server (resolver) must go down.
There is many docs about port forwarding based on nat table and
explanation consider linux box act like nat with two e cards.
thanks,

[ANNOUCE] iproute2 update
A new version of the iproute2 utilities is available to handle the new
extensions for 2.6.7.
* Based on the last known good version of iproute2 from Alexy
* Included most of the vendor patches (except for the stupid ones).
* Got rid of lots of the glibc workarounds, I intend this to build
and run on 2.6 (and 2.4) only.
* Fixed some parsing and formatting bugs.
* Added gigabit as a rate.

NAT & tc filter addresses
Is there a flow diagram as to where tc actions take place with respect
to NAT and other iptables functions on a multihomed box (private &
public NICs) ? Are tc filter rules consulted before or after NATing?
My real interest is in basic understanding first, and then solving a
real problem second.
Example:
Firewall Public NIC 123.123.123.1
Firewall Private NIC 192.168.168.1

Wondershaper
Hi !
I´ve been using the wonderful wondershaper from chapter 15.8 of the
LARTC Howto for some time. It´s really wonderful.
Actually, I use the version from
http://freshmeat.net/projects/wshaper/?topic_id=87
Now I tried to put some hosts to low priority, and it doesn´t work. The
traffic is splitted equally between the noprio and the other hosts.
Is this because I use ip masquerading, and all

Shaping Device Aliases
Hi.
I understand that device aliases (e.g. eth2:3) are not shapeable. Does
anybody know if this functionality is planned in the future?
Anyway, for the time being the only option that seems to leave is to
fwmark packets differently for each device alias and then shape based
on that.
Is it possible to set multiple marks on the packets? Alternatively, is
it possible to check for a specific

htb,iptables
Hi all
I''m sure you have heard this before but sorry.I wrote a script once and
never looked at it again.An as my luck will have it I need it now and it
is gone.I''m trying my best to rewrite it:-(
My 1st question is: If my server is a gateway and I''m marking packets

CBQ_bandwidth
Hi Stef,
Reffering to page < http://www.docum.org/stef.coene/qos/faq/cache/7.html
> I found a para as follows,
" CBQ is not always as accurate as it should be. See docum.org on the
test page for some tests with bounded classes. The algorithm used by cbq
is very "link sensitive". It calculates the link idle time and for that
it needs the real link bandwidth, average

sum of child rates exceeds parent rate
Hi,
i have created a parent class with 45Meg rate/ceiling
Note : The actual traffic flowing via that pc is around 6Meg to 15Meg
I assume the problem will come only when the traffic is more than 45Meg.
Now if i create child classes whose sum of rates crosses more than 45Meg ?
1.How that tc behaves.
2.Will this affect browsing.
Pls let me know this details

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
