Whether it *needs* to do a DNS or not is beside the point. The conclusion is that it appears to be doing a DNS lookup. Could be for nothing more than an IP address of the local machine. How responsive is "nslookup"? Well, just because it looks something up fast is no good measure, but if you can find something it might lookup slow that should be fast then you've found a clue. How fast does it lookup your oT machine and the others on the local net? Wonder if your DNS servers don't know oT and are not authoratative for oT's domain so they go looking upstream DNS servers rather than return an instant "Not Found". As you say in an earlier message o8.com is a non-existent domain. So such a lookup has to go all the way to the root domain servers before that is discovered. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
