need help to resolve (FQDN ;Fully qualified domain name)
1 installing centos 6.4 as the os
2 installing virtualmin ;webmin hosting controlpanal
when installing centos, we get to a stage where it creates a name automaticly ie; localhost.localdomain (also changable)
Now i understand that the domain name localhost.localdomain give by the server represents the server on
on LAN ;local Area Network eg; 192.168.0.8 given port. Also given portforwarding can represent your given server (or more)
publicly, to your given ip address eg; 220.127.116.11
now that we portforwareded our given ip public address, we choose to pay and register a domain name at any of our online registerants.
eg; namecheap online name registers, to point to our ip address. Now that we have a name to represent our online site or server eg; overthehill.com we are ready
to intall virtualmin, webmin, or any other controlpanel. the first question that virtualmin would ask is FQDM… that is the question
that needs to be addressed, is that my pysical servers localhost.localdomain domain name OR registered name i paid for say everthehill.com
also DO we use the nameservers ns1, ns2 we are paying for (overthehill.com) OR our own dns servers that we are using.
I am aspecialy confused about using ns1 and ns2 from our paid regiser nameservers for setting up mail, ie mail man
as i have configured my registered nameserver, and i get errors with mailman, squiral mail etc, i can send but cant recieve, something is wrong.
Another question is Primary Resolver and secondary resover, if you are running a network switch your gateway would be 192.168.0.1 or 10.0.0.1
being the primary resover and your LAN switch leading to where your server (etho) u are using would be say 192.168.0.8, would that be the
would it be correct if i assume FQDN would be the physical server eg: localhost.localdomain and not my paid name, overthehill.com
anyway need help on this. cheers
