Diagnosing _this_ problem should have taken no more than about 30 *seconds*.=20 If you can't get somewhere 'by name', you try to get there 'by address'. If 'by address' works and 'by name' doesn't, *that* is the indication of a DNS problem. If you can't get there 'by address', it is *NOT* a DNS problem, and you=20 start looking for a 'connectivity' problem. The *BASIC* tools for that start with 'traceroute'. Which would have *immediately* (well, within abut ten seconds :) indicated exactly = _where_=20 the problem was. Those who don't understand these kind dof things are "too dangerous" to be trusted with the superuser password. Bluntly, not only do you not know the things you need to know to manage a (even 'personal') network, you "DON'T KNOW _what_ you don't know", and = until you *do* learn the basics, you'll save youself a *LOT* of hair- tearing if you hire someone to solve the problems for you. And miss all the fun by learning by doing :-) /hasse _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to = "freebsd-questions-unsubscribe@freebsd.org"
