Linux setup - What's the significance of the domain
Posted on 2006-04-20
Not really a problem, just a question.
When installing Open Suse 10.2 recently I had to setup the network config. I managed that ok, the box has a static IP on my network and web access works ok.
I understand that you can give your machine a name, and I understand that it can be used to identify the machine instead of it's IP with DNS blah blah. What I'm not entirely sure of is how the domain bit works.
How important is the domain?
My network has no domain that I'm aware of. Is the domain only significant if my network uses domains?
Is there anything (applications etc) that wont work if I don't have a sensible or meaningful domain name set on the box?
I'm a Ingres DBA and will be mainly using the box whilst I train as an Oracle DBA. Does anybody know if Oracle is sensitive to the domain that the box uses?
