mgen & tc
Hello,
I have the following proplem. My DiffServ configuration is working fine
when I do ping, but when I use mgen the packets are not detected at the
core router.
Here is my core router configuration:

tc filter add dev eth1 parent 1:0 protocol ip prio 1 tcindex mask 0xfc

Gred/dsmark/htb
Hi, I am trying to get assured forwarding/expedited forwarding with gred and htb working. Below is the script I am using.
The following steps are what I thing is how the script works. My problem is that if I remove the HTB qdisc from the script and have the GREDS parent as the dsmark it works, but when I add the htb as a parent of GRED and DSmark the parent of htb it does not work?

EF & AF filters with HTB
Hello all,
Please could someone help me with this, I have been trying for days to
get this to work. I would like to have BE, AF & EF classes with HTB
qdisc.
I can''t find any scripts online where this has been done.
If I enable this filter:
#tc filter add dev eth0 parent 2:0 protocol ip prio 1 \
#tcindex mask 0xf0 shift 4 pass_on
then BE & AF classification seems to be fine but

The effects of queueing on delay
I have a router with 3 network interfaces like in the following ASCII
diagram below. All interfaces are 100mbit. There is tcp traffic being
sent from net1 to net3 and from net2 to net3 and the tcp connections
consume as much bandwidth as possible. There is a pfifo queue on the
egress interface eth0 of the core router with a limit of 10 packets.
net1 --> (eth1) router (eth0) -> net3

P2P shaping, won''t work
Hello, its me again, I won''t stop sending emails to this list, until I solve
this problem, I''ve tried several apps to create the right htb rules (even
made them my self), but I always get the same results, traffic gets shaped,
but I can''t use my bandwidth, and this is weird, because I should be able to,
also I keep seeing download being limited too, and that

DSCP, ToS and Egress
I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I
would like to strip the DSCP and possibly replace it with normal ToS bits on
egress traffic leaving my network. Leaving DSCP set is pointless, and could
potentially cause problems with some ISPs that use DSCP internally I suppose.
Setting ToS bits would seem ideal as most networks still honor it to varying

PPPoE and shaping
Hi all,
I have a little problem with my home-made slackware linux server.
Here is the scenario:
1. I have a local wifi network
2. my server do masquerading and exit in internet via a PPPoE connection
Goals:
1. not use SQUID
2. shaping the traffic with classes
3. emule connection must have minimum priority and a band-limit of
10KBytes/s in uplink (server--->internet)
Any idea?
Thx,
Diego

Too slow computer?

It routes packages based on their destination on the

HTB shaping & borrowing info
Hello to everybody,
We want integrate in a router/firewall (Debian Based, 2.6 Kernel), an HTB
shaper.
The goal is to divide the traffic for classes of workstations, at example in
three classes,
let say A, B and C.
Example:
A 70 Mb/s
B 20 Mb/s
C 10 Mb/s
If B don''t make traffic, 7/8 of 20Mb/s must be assigned to A and all the
rest at B
We have used CBQ and HTB, with poor succes.

forwarding in tcng
Hi!
I am learning tcng without having experiance of tc and I am trying to
build something that shall schedule traffic dependent on the value in the
IPv4 packets ip_ttl field.
I have read the tcng reference manual and cannot find information about
forwarding. Is it possible to farward packets from ingress to egress
without sending them upwards in layers?

why isn''t 1:1 getting the traffic? [filter question]
With the below script, whenever I ping 10.0.16.10 (which matches the
only filter I have), traffic still get''s sent to the default 1:2 class
instead of 1:1 and I don''t know why... Any hints?

HTB traffic shaping odd effects
Hi,
I''m trying to perform some (what I consider) basic traffic shaping on
our network utilising HTB. I have mostly reused the example on the
lartc.org site:
tc qdisc add dev eth0 root handle 1: htb default 10
tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 24k
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50mbit ceil
80mbit burst 19k
tc class add dev eth0

Unexpected results using HTB qdisc
Hi All,
I am using the script below to limit download rates and manage traffic for a certain IP address and testing the results using iperf. The rate that iperf reports is much higher than the rate I have configured for the HTB qdisc. It''s probably just some newbie trap that''s messing things up but I''m buggered if I can see it.

Warnings with and without r2q
Hi everyone,
My HTB script is showing me those "r2q change" warnings. I read that I
should test with r2q values to gain accuracy and stop the warnings but I
made some tests with r2q and with burst and I still get the warnings. Any
ideas on this issue will be very helpful. The script seems to be working as
the bandwidth for the IPs is being shaped.

Now to make only Traffic Priority
Hi to everybody.
I read some info and documentation but i still can''t find how to make
this simple setup for example .
I just want to make priority of certain traffic without shaping the
traffic .
For example SSH and RDP first priority
Mail second priority
WEB and FTP third
And everything else last priority.
What will be the simple and best way to achieve this.
I will appreciate
