hello bro omer and sorry for delay , was lil busy , lets discuss it as well..
the main DNS for server means convert the ip to the domain name y've set as primer domian for ur server and this step should be done from ur DOMAIn control panel, say u have omer4ever.com domain , and you jut got a brand new server you want to link the domain with you server , 1st of all you well at least 2 ips with the new server to set ur main DNS , all you have to do just check ur domain control panel and look up for 2 boxs named under NS1 and NS2 should be a blank boxs , put the 2 ips you've got from the company in both box say 193.55.133.1 and 193.55.133.2
and save ur setting and waite 24-48 hours till itz effects , now next step is adding the main dns setting in ur server you have to check httpd.conf to make sure everythinks are installed as well , you well find httpd in this localation /usr/local/apache/conf/httpd.config
after checking it go to pico /etc/resolv.conf and set the 2 ips there as
nameserver1 193.55.133.1
nameserver2 193.55.133.12
and save the config and rehash httpd service by service httpd restart ,
now you have set the primery dns for ur server and you can set resller dns zone from webhosting manager control panel its a very easywahy just check EDITE DNS ZONE
and assigne more ip for another domain and creat a quote with resller permission bala bala bala,
thats all i hope i clear up the dns image,
for more clearfications feel free to ask me again here
my best regards
urs
