    Hi,

    just looking to clarify something here in relation to Linux and how the system looks up an IP address for a name.

    I am looking to move an old server on to a new one. There are a lot of web services setup that have the old server name in scripts and I would like the option of testing one to ensure it works correctly, or more to the point, if it doesn't work, I want to revert back to the old server while I figure out the problem. To do this, I want to change the IP address temporarily (to an available one) on the new server.

    What is the order Linux uses to convert names into addresses?
    Am I correct in saying that, for a test client Linux machine, I can change the /etc/hosts file to point to the (temporary) IP address of the new server, edit the order for the hosts entry to files, dns (left to right) in the nsswitch.conf file, I can then test functionality of a web service while other devices on the network will still happily be directed to the old server?
