I am new to using tc and netem. I want to delay packets being sent to a specific IP address. However, the commands below cause all packets on the system to be delayed, instead of just to the IP address 220.127.116.11:
tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:1 handle 2: netem delay 500ms tc filter add dev eth0 parent 1:0 protocol ip pref 55 handle ::55 u32 match ip dst 18.104.22.168 flowid 2:1
My guess is that I need some kind of catch-all filter at the end to specify that all remaining traffic should not go through netem. But I can't get anything to work. How would I get this to work?
