I am a DNS newbie. I have read some things and i dont understand basically how it all works on linux but i need some help.
What i am trying to acheive is being able to create my own subdomains and have internet users access them.
for example fun.mydomain.com should reach a server that hosts the fun application.
I have registered mydomain.com and the registrar also provides hosting serverices. So if someone goes to mydomain.com they will reach my host's IP.
this poses a problem because the FUN server is NOT with the host but its in my local internal network.
my current network has a DSL router and a linux box hosting the fun application.
how exactly do i map fun.mydomain.com to this computer rather than my web hosts computer?
from the tutorials i have read it seems that BIND handles domains and subdomains. So do i have to tell my domain host/registrar that i am going to handle the domains myself and that he should not associate mydomain.com to his ip?? Do i have to somehow use the name severs the host gave me and put it in resolv.conf so peopel can access fun.mydomain.com?
Thanks for the clarification.
edit: the host only provides HTTP/ftp requests rerouting. so If i get an http request i can route it to my local ip address and it works. except the FUN application does not use the http or ftp protocol. my routers and firewalls are all set up correctly so i dont need any help on that. Its just that i am unsure how to create subdomains when the main domain is managed by another computer.
You'll need access to the domain's DNS server configuration, which is usually provided by either the host or registar. Who controls the nameservers for your domain? http://www.dnsreport.com/ will list them if you're not sure. Anyway, unless you have access to the nameservers or can get whomever controls them to add an NS record for "fun.mydomain.com" that points to your IP, you're probably not going to get it to work the way you want.
You registrar should provide services for adding records to the zone file for your domain. You should be able to add an A record that points to your IP, if you want to run your own DNS servers then you need to make name servers that point to your IP and make your domain use them nameservers instead of the registrars, all this is done through the registrars web interface.
You then need to set up the DNS software on your own computer, if you want to use BIND then you *really* need to read the documentation for it, it can be complex and a bit daunting for those who are new to it. I like nsd from ninetlabs, its a simple authoritive only dns server and is very easy to configure and has never let me down *touch wood*
