> That's wrong. You only need a single static IP address to run DNS. Technically, yes. I like redundancy though, especially for e-mail. If you have one box that does web/e-mail/DNS, and that box goes down, web users and e-mail senders are given an error that you don't exist. If you have redundant DNS, you get an error that you exist, but can't be found. The difference is that with a single box, e-mail bounces immediately whereas with redundant boxes your e-mail is held for up to five days before bouncing. This gives you time to get the box up without losing any messages. -Brian _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
