[FX.php List] [OFF] Question about RDNS

[Leo R. Lundgren]

Jonathan,

I think you shouldn't try to make them behave like the same machine,  
it's not in the nature of what you're doing. For example, are you  
expecting a client to go to the IP of machine A, look up its domain  
name, and based on the result from that query, go to machine B? Seems  
awkward to me :)

Anyhow, I would give both machines their own name, and put them under  
your domain. For example, luke.yourdomain.com and  
leya.yourdomain.com, or fm.yourdomain.com and www.yourdomain.com.  
After that it's a question about what services you have on the  
servers and what domains you need to respond to. For example, you  
need to configure your httpd on the second machine to listen to  
www.yourdomain.com and likely yourdomain.com as well. But ground up  
they are two different machines.

Of course, there are ways to let users connect to one domain name/ 
address only, like for example if you have a router in front of your  
servers you can probably set it up to direct Filemaker traffic to  
your fm server (a possible scenario if you need to support both some  
webbased service and direct fm connections). But this is a second  
question.
