lost packets, network latency and rate limit for testing purpose

störfunk

linux:
 
# drop packets (10% probability)
 
iptables -A INPUT -m statistic --mode random --probability 0.1 -j DROP
iptables -A OUTPUT -m statistic --mode random --probability 0.1 -j DROP
 
# drop packets (10% probability), add latency (500ms) and limit bandwidth (1Mbps)
 
tc qdisc add dev eth0 root netem delay 250ms loss 10% rate 1mbps
