Um, is there something wrong with having multiple DNS servers in resolv.conf? Other than having to time out on #1 before you try #2?

You're probably right; clustercpy or rsync would work better if you have admin access to all the machines in question. The nice thing about the DNS method is that you wouldn't necessarily have to have that access on an ongoing basis. -Doug ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
