[LARTC] IMQ
Hello I have a server with a dsl connection on eth1 and local interface eth0. Because of the NAT i cannot direct traffic to IMQ device in PREROUTING chain but have to use INPUT and FORWARD. So i use rules. iptables -t mangle -A INPUT -i eth1 -j IMQ --todev 0 iptables -t mangle -A FORWARD -i eth1 -j IMQ --todev 0 And now the strange thing: FORWARD traffic gets directed nicely to the IMQ, but INPUT *doesn't* ! To be just sure i removed "FORWARD" line and left only the "INPUT" (other mangle rules were removed) Chain INPUT (policy ACCEPT 3511 packets, 2753307 bytes) pkts bytes target prot opt in out source destination 343 439847 IMQall -- eth1 any anywhere anywhere IMQ: todev 0 But when i check IMQ0 using ifconfig: imq0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 UP RUNNING NOARP MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:30 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) i see there is no traffic going through this device! Anyone knows how can it be possible ? -- best regards, Marcin 'Yans' Bazarnik [EMAIL PROTECTED] ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
[LARTC] HTB problem (yet another one?)
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}
endeavour:~# ip link show
1: lo: mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:50:ba:d4:9d:50 brd ff:ff:ff:ff:ff:ff
3: eth1: mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:48:54:55:54:d1 brd ff:ff:ff:ff:ff:ff
4: eth2: mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:a0:24:d5:ae:33 brd ff:ff:ff:ff:ff:ff
5: ppp0: mtu 1656 qdisc pfifo_fast qlen 3
link/ppp
6: ppp1: mtu 1656 qdisc pfifo_fast qlen 3
link/ppp
7: imq0: mtu 1500 qdisc pfifo_fast qlen 30
link/void
I should have all the needed modules also:

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 ?
