Hi,

I have nameserver running. I can ping www.mydomain.com . But I cannot ping mydomain.com , it says Unknown host. What should I add in my zone file?

Thanks.

Using Slackware 9.1

Another thing is when I set nameserver 127.0.0.1 in /etc/resolv.conf, I cannot ping some address (such as www.linuxquestions.org , www.tpg.com.au ). However, when I set the nameserver to the IP of the machine (144.136.235.196), it works just fine. I though both IP should work, since they're pointing to the same machine?

Thanks.

dns can be a major pain in the ass. The second problem "looks like" you are having problems with the forwarding dns. (that's the name, right?)

If you are asking a dns server about one domain and the server doesn't know about it, it has to ask someother dns server for it... that's the forwarding server. You have it correctly configured?

Always remember to use tcpdump.... you can save yourself major amounts of time by using it to monitor network activity.

My bad, I forgot about forwarding server, works fine now. Just left with the first problem.

The reason is because I want to have email address like user@domain.com , instead of user@host.domain.com . However, if I put my email address as user@domain.com, some mail server will return the email, saying they cannot contact domain.com. Still working on it.

Oh, by the way. Say I bought domain.com , and at the provider, I created child nameserver of my machine ip, and i stick that child nameserver to the Primary/Secondary DNS for domain.com. Now, the question is whether domain.com has an IP mapped to it or not? Otherwise, if anyone have any idea how I map my machine ip to domain.com (currently it's mapped to host.domain.com).

Thanks a bunch!

Well.... I'm not much of a dns guru (too far from it)... but I think there is a DNS record devoted to mail servers. Am I right?

Thanks anyway.

This is strange. I use nslookup:

-----START-----
>server 61.9.240.14
Default Server: dns1.wa.bigpond.net.au
Address: 61.9.240.14

>domain.com
Server: dns1.wa.bigpond.net.au
Address: 61.9.240.14

Name: domain.com


-----END-----

It does resolve the address, but with no address (IP). Anyone know how to map the given domain (domain.com) to an IP? And whether it has to be done in my domain provider, or in my server?

Thanks.

I did another nslookup:

---START---
user@host:$ nslookup
Note: nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead. Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
> server a.root-servers.net
Default server: a.root-servers.net
Address: 198.41.0.4#53

> www.domain.com
Server: a.root-servers.net
Address: 198.41.0.4#53

Non-authoritative answer:
www.domain.com canonical name = host.domain.com.
Name: host.domain.com (##1)
Address: 144.136.235.196
---END---

Now, anyone know what I need to configure, so that other nameserver see the machine as domain.com, instead of host.domain.com (see ##1 above)?

Thanks. Still struggling.

Solved!
