iptables IMQ command problem

iptables IMQ command problem

[Diego Cabrero]

Hi everybody,
Here is my situation:
First of all, i need control over the downlink bandwith, so i patched 
kernel (2.4.28), iptables (1.2.11) so that i get IMQ support (imq0 and 
imq1), but when i run the traffic control script i've got an error on 
this line:

iptables -t mangle -A PREROUTING -i eth1 -j IMQ --todev 0

The error report is:
iptables v1.2.11: Unknown arg `--todev'
Try `iptables -h' or 'iptables --help' for more information.
RTNETLINK answers: Invalid argument
RTNETLINK answers: No such file or directory
RTNETLINK answers: No such file or directory

I've tried a lot of things like change the file's ".IMQ-test" mode , 
check if todev variable exist (it does), don't know what could be next, 
i'd appreciate some help.

Thanks.

Is it not supposed to be installed since imq0 and imq1 are working?

Also i compiled kernel choosing IMQ device module option. Insmod the 
imq.o driver as well, but still does not work. There must be something else.

Here is the list of modules loaded while i execute the command.

Controling Inbound and Outbound traffic simultaneusly.

[Diego Cabrero]

Hi,

I'm Running two independent traffic applications between two computers 
conected point to point each other, at the same time each of these 
applications are generating trafficin one direction so i have two 
independent traffics traveling througth the same channel.

Figure:
                eth1, PC1 ---------app1-----------> eth1, PC2
                                <--------app2------------

My problem is that i am trying to control the whole inbound and outbound 
traffic through PC1 (by using IMQ for ingress) but it seems like they 
are connected somehow.

This is the script i am using:
---------------------------
Inbound control commands:
            tc qdisc add dev imq0 root handle 1: htb
            tc class add dev imq0 parent 1: classid 1:1 htb rate 
${INBOUND}kbps ceil  ${INBOUND}kbps
            iptables -t mangle -A PREROUTING -i eth1 -j MARK --set-mark 1
            tc filter add dev imq0 protocol ip parent 1:0 handle 1 fw 
flowid 1:1
            iptables -t mangle -A PREROUTING -i eth1 -j IMQ --todev 0

Outbound control commands:
            tc qdisc add dev eth1 root handle 2: htb
            tc class add dev eth1 parent 2: classid 2:1 htb rate 
${OUTBOUND}kbps ceil  ${OUTBOUND}kbps
            tc filter add dev eth1 protocol ip parent 2:0 prio 3 u32 
match ip dst 0.0.0.0/0 flowid 2:1

Any ideas?

Thanks!!
