Hi all, I installed linux kernel 2.4.18 and iptables 1.2.6a with patches htb3.3_tc.dif iptables-1.2.6a-imq.diff-3 sch_generic.diff I compiled everything without problems. When I tried to run some examples I received this message: ./iptables -t mangle -A prerouting -i eth3 -j IMQ iptables: No chain/target/match by that name I looked for imq.o and I tried insmod imq and I received those messages: /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_unregister_queue_handler_R4df6e6de /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol unregister_netdev_Rf7112b47 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol skb_under_panic_R14a04476 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_register_queue_handler_R9d33fd20 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol irq_stat_R79a4281c /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_unregister_hook_Rd74167f6 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_register_hook_R88672625 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol register_netdev_R20a39df5 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol skb_clone_R3e70c0f3 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_reinject_Rb7e7232a /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol qdisc_restart_R5633d4d0 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol __kfree_skb_R57528140 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol netdev_finish_unregister_R9f5d09d5 Where is the problem?

Hi,
I have an 128K wan connection to one of my offices. We are using VOIP on
this connection ..We also carry our data traffic on this line ..Some time , when
the data traffic is high , the voice quality drops drastically ..
I have tried prio queues ..I let the voice traffic use the first band ..And the
other data tarffic third band ..
This makes things a little better ..But not quite well ..
An other problem is ..I both want to priotize and shape my traffic ..
For example ..I want to limit the mail traffic to some kbits ..While I am
letting the voice traffic the best priority ..
I try to use HTB with PRIO qdisc ..But couldnt be succesfull ..
What do you suggest me to make the voice quality good enough ..and shape the
data traffic related to some criteria ?
Thanx
-ms
Hello, can you post your working script about the prio and VOIP. I am doing some prio script but it is not working.

Depending on the protocol, good bandwidth (as opposed to perfect) and very low latency are required. Bandwidth equal to the target bandwidth with very low latency and no fragmentation is perfect. Part of the problem is not knowing your maximum number of VOIP links. In a perfect world, one would use PRIO and mark the VOIP packets as "go now ... do not pass go, do not collect $200". -- Michael T. Babcock
