Change of network id
Just a simple question for most of you, guys.
I have just finished setting up a new Redhat Linux machine to act as mail server with a temporary IP address and name (the symbolic name just before the dot domain) in order to let the original old server run freely while I was preparing the new machine.
Now that everything seems to work fine, I want to shutdown the old machine and let the new one take its place: name and IP.
Where are ALL the places where the name and IP number are stored and must be changed? Which daemons are to be restarted? Please notice that I cannot find anything like ifconfig or similar programs; I ned to do everything manually.
Important running programs are
openssl (I will have to redo the certificate changing the name, I believe)
Thank you very much
