Emulating wide area network delays

Add delay of 100ms:

tc qdisc add dev eth0 root netem delay 100ms

Remove delay:

tc qdisc change dev eth0 root netem delay 0ms

Change delay to 1000ms:

tc qdisc change dev eth0 root netem delay 1000ms

Add random variation to 100ms delay of +/- 10ms:

tc qdisc change dev eth0 root netem delay 100ms 10ms

Add random variation to 100ms delay of +/- 10ms with 25% correlation:

tc qdisc change dev eth0 root netem delay 100ms 10ms 25%
