I have been studying WordPress' multi-site install, which basically involves multiple IP address and domain names on a single server. Apparently, Wordpress has code that keeps the content of different wordpress sites separate, based on the domain name, even though wordpress is installed in a single htdocs directory. Based on that study, I started to look at how I might simulate a server with multiple domains and ip addresses, using a local DNS server on one of my Suse virtual boxes. Alas, I have yet to find a good resource that explains the details of how DNS works and best practices for running a DNS server, or how or even if what I want to try is even possible. I do know how to configure Apache's httpd for multiple virtual hosts, but the DNS, and the domains I'd use for testing, are the sticking points. When I configured a server to have multiple virtual hosts, the domain names were real, and the internal IP addresses were mapped one to one to the external IP addresses for each domain name. In the case of the experiments I want to try, the domain names I'd use are entirely fiticious, but I want to make sure that they do not escape into the cloud (see, my level of ignorance on this matter is that I do not know if that is possible). The DNS question arises in another context, also, in that one of the resources I have been studying to learn how to set up NFS says that a DNS is required since NFS software uses a reverse lookup and may hang if a DNS is not available (though, for that, I want to map the private IP addresses to the machine names rather than to some fictisious domain name). I guess, to maximize my learning about these things, what I am looking for is more a combination of a tutorial and a howto or cookbook document than a reference manual (in the same sense that if I were to teach C++ programming, I'd use one of Stroustrups' books, or that by Koenig and Moo, instead of the latest ANSI C++ standard). Of course, if someone wants to take the time to write a response that helps me learn about these things, that too would be appreciated. ;-) Thanks Ted -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
