Hello
I have a small (maybe typical?) problem with HTB. Present configuration is:
Kernel: 2.4.20-pre4 (with HTB, IMQ)
endeavour:/var/log# tc -V
tc utility, iproute2-ss010824
Which should support HTB because writes help for it ;-)
endeavour:~# tc qdisc add dev imq0 root handle 1 htb ttt
What is "ttt"?
Usage: ... qdisc add ... htb [default N] [r2q N]
default number of class to which unclassified packets are sent {1}
<and so on>
endeavour:~# ip link show
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,ALLMULTI,UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:50:ba:d4:9d:50 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:48:54:55:54:d1 brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST,ALLMULTI,UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:a0:24:d5:ae:33 brd ff:ff:ff:ff:ff:ff
5: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP> mtu 1656 qdisc pfifo_fast qlen 3
link/ppp
6: ppp1: <POINTOPOINT,MULTICAST,NOARP,UP> mtu 1656 qdisc pfifo_fast qlen 3
link/ppp
7: imq0: <NOARP,UP> mtu 1500 qdisc pfifo_fast qlen 30
link/void
I should have all the needed modules also:
endeavour:~# lsmod

ipt_nth ipt_REJECT iptable_filter iptable_nat]
-------------------------------------------------------------------------
And the PROBLEM:
When i try to add qdisc to the imq device.. a get:
endeavour:~# tc qdisc add dev imq0 root handle 1 htb default 20 r2q 10
RTNETLINK answers: Invalid argument
-------------------------------------------------------------------------
BTW: Adding CBQ qdisc to imq0 works fine... Any suggestions ?
