Hi, I know this might not be 100% on-topic and might be better suited for a Linux-distro mailinglist, but I hope to get more diverse methods from you networking experts. Basically, I have a small residential connection, 5 Mbit down, 0.5 Mbit up. A user on my local network, who we will call 192.168.1.105, is using too much bandwidth. I have tried social engineering to get him to stop, he claims to, but iftop says otherwise. My network is setup like this: Cable modem goes to eth0 on router running Ubuntu server, eth1 on the Ubuntu box goes to a wrt54gl (behaving purely as a bridge), and all clients are connected wirelessly. The Ubuntu box handles everything. So I have tried this script, and it does not work -- download speed gets limited just fine, but upload remains unlimited for some reason: TC=/sbin/tc OUTIF=eth0 # Interface for WAN (internet) INIF=eth1 # Interface for LAN (internal network) DNLD=0.5mbit # DOWNLOAD Limit UPLD=0.1mbit # UPLOAD Limit IP=192.168.1.105 U32="$TC filter add dev $IF protocol ip parent 1:0 prio 1 u32" $TC qdisc del dev $INIF root $TC qdisc del dev $OUTIF root $TC qdisc add dev $INIF root handle 1: htb default 30 $TC qdisc add dev $OUTIF root handle 1: htb default 30 $TC class add dev $INIF parent 1: classid 1:1 htb rate $DNLD ceil $DNLD $TC class add dev $OUTIF parent 1: classid 1:1 htb rate $UPLD ceil $UPLD $TC filter add dev $INIF parent 1:0 ip pref 1 u32 match ip src $IP/32 0xFFFFFFFF flowid 1:1 $TC filter add dev $OUTIF parent 1:0 ip pref 1 u32 match ip dst $IP/32 0xFFFFFFFF flowid 1:1 Anyone see any problems in my setup, this script, or have any idea how I can limit the speeds of Mr. 192.168.1.105 without social engineering? Thank you for your time.
