It is a number that starts at .75*(3600 s) and goes down by 25% every ten minutes until there are either less than 128 unreferenced entries in the per-host cache, or the value gets down to 10 s. You need to think about how many different systems regularly start TCP connections to your machine and what sort of performance-memory tradeoff you want to make, and adjust these MIB variables accordingly: net.inet.ip.rtexpire: 3600 net.inet.ip.rtminexpire: 10 net.inet.ip.rtmaxcache: 128 -GAWollman -- Garrett A.
