Problems with the configuration of my DNS...
 

Good day...

(My English isn't good...)
I have a problem with my server (O.S. Fedora Core 6). I pay for hosting to a ISP of my country, and I must to pointer my server at his DNS.

My first problem is that my server has no name...well, I used the network tools of http: // network-tools.com/ and this site show me that my server has no name. I am a new user of Linux Fedora Core 6, and I don't know how to configure my host name...

My second problem is that I exactly don't know how to pointer at the DNS of my ISP, I try to do it with the "Server Manager", but I don't secure that I am right...

Excuse my grammatical errors, and I hope that you can help me with my troubles...thank you for your time, Farewell...

As I understand, you want your system to use a remote nameserver to do DNS queries.

If the ISP's nameserver is at IP address 10.1.2.3, then you need a line in /etc/resolv.conf like so:


As for your system having no name... You can assign a hostname to your system, but that name will not be visible to the outside world -- if you want a specific name visible to the world, you must arrange to have a name/IP address mapping added to DNS.

For example, if your ISP has the address isp.com and you want your system to appear as myserver.isp.com, you would have to have the ISP add a pointer to your system to their DNS server. On the other hand, if you want a domain name all of your own -- such as www.mydomain.com -- then you need to register it with a domain registrar and then arrange for them to point that name at your server's IP address.

I have my domain registered, but I must to pointer at the DNS's of my ISP...this for give at my server more protection...I will try the solution that you give me, thank you for your time...

Hello...

Well, I try the solution that you proposed to me...
I use again the web page www.networ-tools.com, and I choise the "Lookup" option, and this show the next message:

IP address: 200.26.142.xxx (I hide this last numbers for security)
No host name is associated with this IP address or no reverse lookup is configured.

Error:Host not found

200.26.142.xxx is from Colombia(CO) in region South and Central America


And now, if I use the "DNS Record" option, the web page show me:
No host name is associated with this IP address or no reverse lookup is configured.
