About 2years ago, I used the below script on a CentOS 4.4 box acting as a firewall (iptables), routing (iproute2) and squid 2.5 transparent intercepting. #traffic shaping on eth1 - i.e: LAN INTERFACE (For Downloading). eth0 is connected to the Internet INTERFAZ_LAN=eth1 FULLBANDWIDTH=256 BANDWIDTH4LAN=64 tc qdisc del root dev $INTERFAZ_LAN tc qdisc add dev $INTERFAZ_LAN root handle 1: htb r2q 4 tc class add dev $INTERFAZ_LAN parent 1: classid 1:1 htb rate "$FULLBANDWIDTH"Kbit tc class add dev $INTERFAZ_LAN parent 1:1 classid 1:10 htb rate "$BANDWIDTH4LAN"Kbit tc qdisc add dev $INTERFAZ_LAN parent 1:10 handle 10: sfq perturb 10 tc filter add dev $INTERFAZ_LAN parent 1: protocol ip prio 1 u32 match ip dst 192.168.100.0/24 classid 1:10 192.168.100.0/24 is my LAN RANGE. According to the above script, My FULL bandwidth was 256 kbit. I allocated 64 kbit for downloading. it is actually NOTHING to do with squid for me. ALL went fine with iproute2 pkg. > I am also seeking a TC expert to help several users already needing to use > it with TPROXYv4 and/or WCCP setups. I am NOT a tc expert. just a guy with an interest. -- Thank you Indunil Jayasooriya
