I'd like to use tc and netem to cause network delay, but only to
certain other machines.
I found this page which (apparently) describes how to do it:
I can get outgoing network delay using:
tc qdisc add dev eth0 root netem delay 200ms
but this adds latency to all outbound traffic.
Further down the page I linked to above, it mentions how to delay to
only one IP address and gives the following code:
tc qdisc add dev eth0 root handle 1: prio
tc qdisc add dev eth0 parent 1:3 handle 30: netem \
delay 200ms 10ms distribution normal
tc qdisc add dev eth0 parent 30:1 tbf rate 20kbit buffer 1600 limit
tc filter add dev eth0 protocol ip parent 1:0 prio 3 u32 \
match ip dst 188.8.131.52/32 flowid 10:3
However, when I've tried this, I get network delay to all ip addresses
- I can't seem to filter to just one ip address.
Does anyone know the solution?
