Is your network acting a bit too reliable?

Is your firewall operating at peak efficiency?

Are your users getting complacent?

If you answered “Yes” to any of the above, run the following two commands to spice things up a bit:

1
2

iptables -I INPUT 1 -m statistic --mode random --probability 0.25 -j DROP
iptables -I OUTPUT 1 -m statistic --mode random --probability 0.25 -j DROP

Run this one to bring your networks back to proper speeds:

1
2
3
4

for IF in $(ip l | awk -F': ' '/^[0-9]/{print $2}')
do
  ip l s ${IF} mtu 68
done

Routing lookups taking too long? Network link saturated? Use this one!
