I want to debug a network program when it encounters problems
(timeouted connections, delays, etc). So I need to be able to
configure an interface with things like "drop 50 % of packets directed
to port 80".

On FreeBSD, there is dummynet
( which seems to do
everything I want but does not appear to be available on NetBSD.

On Linux, there is the "random" plugin of Netfilter
less featureful but probably sufficient for me.

Any NetBSD solution?
