Actually, I believe a realm is a name for a collection of servers. From a client's standpoint, it doesn't matter which one is the scm or if an scm is even available. > record, that's used. If not, name (or IP I guess) is used as SCM. Right, that's how it should work. But if the name can't be looked up in dns, it fails. It only checks the /etc/hosts file (as far as I can tell) when a machine name is referenced in a realm definition. > are you trying to set up a new realm with a replicated server, or add > a replicated server to your existing realm?

I'm sure there must be another way. Otherwise how could you test your servers in a live environment. If you take down the scm and it turns out your replica didn't have the files, then you just disconnected all your clients. > You may want to have multiple scms and multiple servers, so you can One scm is plenty. -- Patrick Walsh eSoft Incorporated 303.444.1600 x3350 http://www.esoft.com/Received on 2005-04-08 10:43:40
