I'm trying to shape bandwidth but with no success. I have a Linux server with 3 networks (WAN, LAN and DMZ). In the DMZ I have a server (IP 172.21.1.2) that I wish to grant a 25kbit bandwidth (from a total of 256kbit coming from the WAN). To accomplish this, I setup Linux to allow the use of IMQ devices. I wrote the following script (eth1 is WAN, eth2 is DMZ): #!/bin/sh modprobe imq numdevs=1 tc qdisc add dev imq0 root handle 1: htb default 20 r2q 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 256kbit ceil 256kbit tc class add dev imq0 parent 1:1 classid 1:10 htb rate 25kbit ceil 256kbit tc class add dev imq0 parent 1:1 classid 1:20 htb rate 231kbit ceil 256kbit tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 match ip src 172.21.1.2 flowid 1:10 tc filter add dev imq0 protocol ip parent 1:0 prio 2 u32 match ip dst 172.21.1.2 flowid 1:10 iptables -t mangle -A POSTROUTING -o eth1 -j IMQ --todev 0 iptables -t mangle -A POSTROUTING -o eth2 -j IMQ --todev 0 iptables -t mangle -A PREROUTING -i eth2 -j IMQ --todev 0 The output of 'tc -s -d qdisc ls dev imq0' is: qdisc htb 1: r2q 1 default 20 direct_packets_stat 0 ver 3.10 Sent 0 bytes 0 pkts (dropped 0, overlimits 0) This output is after running the script for a while, the statistics shouldn't be 0, should they? Anybody know what I did wrong? Any help will be appreciated :) Toshiro. -- Toshiro Viera <tviera@arnaldocastro.com.uy>
