Hello, have HTB „rules“ in 4 different ISPs and i
control for each customer this way: Flush and 1:0 class tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1:0 htb tc class add dev eth0 parent 1:0 classid 1:1 htb rate
100mbit tc qdisc del dev eth1 root tc qdisc add dev eth1 root handle 1:0 htb tc class add dev eth1 parent 1:0 classid 1:1 htb rate
100mbit Upload and Download: user1 tc class add dev eth0 parent 1:1 classid 1:5 htb rate
150kbit ceil 150kbit tc qdisc add dev eth0 parent 1:5 handle 5: sfq perturb 10 tc class add dev eth1 parent 1:1 classid 1:5 htb rate 50kbit
ceil 50kbit tc qdisc add dev eth1 parent 1:5 handle 5: sfq perturb 10 iptables -t mangle -A POSTROUTING --dest x.x.x.x -o eth0 -j
CLASSIFY --set-class 1:5 iptables -t mangle -A FORWARD --src x.x.x.x -o eth1 -j
CLASSIFY --set-class 1:5 Upload and Download: user2 tc class add dev eth0 parent 1:1 classid 1:8 htb rate
150kbit ceil 150kbit tc qdisc add dev eth0 parent 1:8 handle 8: sfq perturb 10 tc class add dev eth1 parent 1:1 classid 1:8 htb rate 50kbit
ceil 50kbit tc qdisc add dev eth1 parent 1:8 handle 8: sfq perturb 10 iptables -t mangle -A POSTROUTING --dest y.y.y.y -o eth0 -j
CLASSIFY --set-class 1:8 iptables -t mangle -A FORWARD --src y.y.y.y -o eth1 -j
CLASSIFY --set-class 1:8 (…) This rules works fine, but just for less than 1.700
customers. More than 1.700 customers, i have my load avarage in the sky and
Ksoftirqd process (top information) in 100% fulltime. I don’t know why. I
used to use CBQ instead HTB because i had the same problem and Ron (a guy in
this list) gave this rules and told me that he uses this for more than 3.000
customers. I tested it in more than 7 different computers (but the same hadware
specifications) and i had the same problem with either CBQ or HTB rules. The
computers that i have are all of them DELL PowerEdge 1850. I will put some
hardware iformations here: top PID USER
