I'm after running this command to simulate a network latency of 500ms with 100ms std deviation:

tc qdisc add dev eth2 root netem delay 500ms 100ms

Trouble is, I forget how to cancel this command! My computer currently has an awful latency and I don't know how to get rid of it!

Many thanks in advance,

# tc qdisc del dev eth2 root
# tc -s qdisc ls dev eth2

Should clear all rules on eth2.

I hope this answer will get to you before night ;) – petrus Jul 4 '11 at 16:50
An O/S restart also should clear the rules. When in doubt, reboot. – the-wabbit Jul 4 '11 at 16:58
