The current man page for resolv.conf(5) says the default timeout is 5 secs, and the apps behave as if that were true. There's an option to tweak the timeout, and it's been suggested to shorten the time, since on a local lookup if you don't get an answer in 1 sec you're never going to get it -- but the timeout applies to global lookups too, which can take longer legitimately, if several stages of forwarders and recursion are involved. > I'll have a look and see if I can put something together for you to > test. Thanks for looking into this -- I'll test the package on one of the machines running 5.0.2 presently. James F.
