qdisc monitoring
Hello,
I am interrested in the monitoring of the qos qdiscs parameters such as size
of the queue, enqueues, dequeues, delay in queue, I made a tool to have
those
results availlable at http://rawsoft.org, but it will probably not work
anymore
because of the kernel evolutions (the file sch_red.c is patched for the
tool to work).
I would like to have all the necessary data coming from the kernel so as to
monitor the qdisc queues in a real time way without kernel modification.
Could I have a modified sch_red.c or sch_fifo.c that would contain hooks to
monitor and bring back the results to...

HTB. QoS and Shorewall
Group,
I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source.
Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

Two u32 problems: module count and fw
...x10 0xff flowid 10:010
# /sbin/tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip
dst 192.9.203.57 flowid 10:010
Though u32 is used twich here I can get only one refrence count in lsmod
# lsmod
Module Size Used by
cls_u32 4944 1 (autoclean)
sch_red 2464 1 (autoclean)
Now if I create one more class on same device(eth0) and use u32 filter to
classifiy my traffic then also this count remains same(Isnt surprising?)
# /sbin/tc class add dev eth0 parent 10:0 classid 10:2 cbq bandwidth 100Mbit

[Bug 529] New: OOPS in nf_conntrack_ipv6 with fragmented UDPv6
...her box) OOPSes.
tcpdump suggests the problem appears as soon as my client sends
fragmented UDPv6 packets towards the destination. It does not happen
when nf_conntrack_ipv6 is not loaded. This is the OOPS as dumped from
the serial console:

New queing discipline
I want to implement a new queuing discipline for the tool tc. The new
queuing discipline would support the application of multiple threads
on the same queue with different kinds of traffic. Each kind of packet
will have its own drop probability but while calculating the average
queue length, the no. of packets in the queue will be equal to the
sum of the individual no. of packets(of the different

Scheduler Mechnisms!
Hello,
Normally, in addition to such qdisc scheduler mechanisms as FIFO, PQ, WRR, WFQ,
are there any more? Then, there is a confusion on scheduler in Linux enviroment:
Assume there is a qdisc, such as RED as a leaf qdisc in a router, we know, if
there is packet which want to enqueue the packet, the Function red_enqueue is
called, but when the packet leave the queue(when the Function red_dequeue
