Hi everybody,

I am trying to do some bandwidth management testing, so i have developed a small script for doing so. When i try to run it it gives the error <error> RTNETLINK answers: invalid argument</error>

can anyone point out the problem? i have searched the net, and so far they say it has to do something with the kernel support.

the script:
<code>
tc qdisc add dev eth1 root handle 1: htb
tc class add dev eth1 parent 1: classid 1:1 htb rate 2mbit ceil 2mbit
tc class add dev eth1 parent 1:1 classid 1:10 htb rate 600kbit ceil 2mbit prio 2
tc class add dev eth1 parent 1:1 classid 1:20 htb rate 1400kbit ceil 2mbit
tc class add dev eth1 parent 1:20 classid 20:100 htb rate 700kbit ceil 2mbit prio 0 #when running this command it gives the error
tc class add dev eth1 parent 1:20 classid 20:200 htb rate 700kbit ceil 2mbit pro 1
</code>

P.S: i am running this script on a virtual machine that has ubuntu 9.04 installed.

Hi there,

are you still stuck on this problem? If so, it may be as little as a typo, if your #comment refers to the following line:
Note the bold part - that should read prio, no?

By the way, for using the code tags, you must use [square] brackets around the word "code".

Kind regards.
