DNS Problem

[kennethwu]

I dunno why i using my dns server,it cannot resolve names in domains not handled by myself,i only can resolve those handled by myself

[till]

Thst the normal behaviour of mydns, as mydns does not dontain a resolver library. Solution is to install a dns resolver like dnsmasq.

Follow the steps that are described in the chapter "Installing DNSMasq" from here (and only this chapter and not the whole tutorial):

http://www.howtoforge.com/mydns_mydn...on_ubuntu_edgy

[kennethwu]

Thanks,but after i install the DNSMasq still cannot solve the domain,is that the config problem?

[till]

1) Have you reconfigured the mydns.conf file as described?
2) Have you restarted mydns?
3) Post the content of /etc/resolv.conf

[kennethwu]

I have changed that but still not working

nameserver 127.0.0.1
search hkhost.biz
nameserver 203.80.96.10
nameserver 203.80.96.9

[falko]

What's in mydns.conf? What's the output of

netstat -tap

?

I have a very similar problem. When I try to bring up my domain name it gets stuck on "resolving host" and then times out. I already switched the name servers over.

When I dig mydomain.com, it yields this:

root@server1:~# dig mydomain.com

This is in my /etc/dnsmasq.conf file:

no-listen = 127.0.0.1
recursive = 127.0.0.1

I followed all of the directions in the tutorial that was linked earlier in this thread. The contents of my configuration files are exactly what that tutorial suggested.




"Netstat -tap" yields this:

Thanks!

I have a very similar problem. Whenever I go to my domain name, it gets stuck on resolving host and then times out. I entered the correct name servers, and it looks like its forwarding when I do a dig mydomain.com:

I followed all the configuration instructions in the tutorial posted above and made the appropriate entries in ISPconfig under DNS and site.


Here is the output of my netstat -tap:

Edit: I also forgot to mention that when I ping my domain name, it does ping my ip address. It never stops pinging it though, and it displays a hostname from my service provider...

I followed the perfect setup guide for ubuntu server 10.04, and everything else seems to be working perfectly. Both ns1.nameserver.com and ns2.nameserver.com point to the same IP address. Is this a problem? I had no problem entering those servers with the registrar.

Does www.intodns.com show any problems for your domain?

[mgillett]

Hehe, quite a few:

NS records from your nameservers:

NS records got from your nameservers listed at the parent NS are:
Oups! I could not get any nameservers from your nameservers (the ones listed at the parent server). Please verify that they are not lame nameservers and are configured properly.


Mismatched NS records

WARNING: One or more of your nameservers did not return any of your NS records.


DNS servers responded

ERROR: One or more of your nameservers did not respond:
The ones that did not responded are: 75.###.38.###


Multiple Nameservers

ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.




Missing nameservers reported by your nameservers:

You should already know that your NS records at your nameservers are missing, so here it is again:

ns1.nameserver.com.
ns2.nameserver.com.



SOA

SOA record No valid SOA record came back!



MX

MX Records
Oh well, I did not detect any MX records so you probably don't have any and if you know you should have then they may be missing at your nameservers!



WWW
WWW A Record
ERROR: I could not get any A records for www.mydomain.com!

(I only do a cache request, if you recently added a WWW A record, it might not show up here.)

Also... Is the intended behavior for my name servers (ns1.nameserver.com, etc) to point to the default server webpage? When I type in ns1.nameserver.com it gives me this message:

It works!

This is the default web page for this server.

The web server software is running but no content has been added, yet.
