So I want to mimic some latency in a test network for DB replication. I am wondering what other's have used for this? Obviously, the best way to would be to actually have one box across the US or across the globe to actually test against but what if you don't have that?
boxes across the globe have the property of being somewhat less deterministic than you'd like if you need repeatability.
IIRC ipfw can do this using dummynet and the delay directive.
it will also do jitter and drop rate... to wit, it's exactly what is need here. there are analogous tools for iptables based platforms.
