    I realize I am posting a few comments related to the same basic question here, but I want to state this:

    Going from the point where one needs to change things by asking someone (like account names for the primary owner in C-Panel WHM) to where you now have to figure out how to do it yourself is one of those "humbling sort of tasks".

    It seems like a simple request, like hey I changed my mind and I dont want to use domain name I decided it makes better sense to go with

    So perhaps I could be pointed to some sort of overview, which explains how one is to use the Terminal in their root server for a VPS (or dedicated) machine [ like the old days when people used the dir command or cd/ or run command in Dos ] to set up up things, and now....

    We have this very powerful program called C-Panel/WHM and how to these two things which seem worlds apart get integrated. If I want to change the name of the VPS server it self , do I have to open a ticket with the company that sold me the VPS (because they really do not seem to want to be bothered with such requests) or can I do it myself with the CentOS 5.6 64 bit-

    How to do it, should I do it? When I establish a new account on C-Panel using WHM and it e-mails the person who "bought the account" does it come from server-name-xyz or does it come from name-xyz@CPanel.

    Does the name of the VMS machine itself have any of its own "DNS" or name server needs? The companies control panel might be Onapp or Hostbill, but there is no knowledge base there. No little videos to watch, to that show you how its done.

    I am thinking thinking that the VPS machine is really doing all the heavy lifting, and processing all the major changes in the background, and C-Panel/WHM is just some convient interface (kind of like Windows is to Dos)- that has a neat little way to tell the "real computer" that horribly user "unfriendly" blinking cursor that even has the nerve to be in black and white!!!

    The things I want to do seem so simple, yet I always want to do it right the 1st time, and then "back it up" and then make the next incremental change.

    Is that the way to approach the thing, how often or what events cause someone to need to rebuild the machine, by pressing that very simple (yet scary looking button).

    Why even a simple thing like changing a root password (something I believe one should do as matter of habit every so often for security) seems like this daunting task when a screen then pops up, and asks-

    Are you sure you want to do this, this will cause the machine to reboot?

    While in reality, the reboot must be the same as good ole "Control, Alt Delete" on our PC's Or simply turning off the machine. BTW, are we ever supposed to log off of our VPS terminal, are we supposed to exit or "shut-down" when we are done.

    Looking for some concept framework, some insight to get the big picture so I can start " Wget " [ing] some files, so I can start creating packages and adding domains, upgrading to Cloud Linux or adding Fantatistico or FTP ing some of my old data-bbases from forgotten websites from the past..

    Overview please, tie it together if you dont mind, or send me to the article that explains all this VPS terminal to C-Panel dependency or interaction.

    I've moved this post out of the old thread you posted to. Please start new threads instead of posting to older threads not directly related to your questions.

    If you want to change the hostname of the machine, that can be done in WHM > Change Hostname area. If you control the domain and the nameservers being used for the hostname, it should be a simple matter of following the steps there to modify it.

    You may need to contact your provider to let them know the new hostname in case their VPS main node has the wrong one listed, since VPS container reboots can cause the hostname to revert.

    Have you tried creating a new account yourself to see what the email shows? It should be sent from the hostname and it normally goes onto the root user contact email as far as I'm aware.

    The hostname does matter, since emails are sent using that hostname and, if it doesn't match the mailhelo response of the server or match the reverse DNS (rDNS) of the IP address, then many recipients of your emails might reject your server's email or place them into spam.

    I cannot say what is the best way to approach making changes. I suggest reading our documentation on WHM for any settings you aren't certain about:

    WHM User Guide

    When I change the root password in WHM on my server, it doesn't mention anything about a reboot. Changing the root password should not require a reboot. If your server has such a message popping up, this was not added by cPanel in any way and you would want to talk to your host about it.

    As for logging off VPS terminal, so long as you aren't issuing a shutdown or reboot command but simply typing "exit" without the quotes, then you should be fine.

    There is no one article that can explain everything to you. You are welcome to ask questions, but it is mainly reviewing the documentation that does exist and learning as you go.
