Howto: Setup a DNS server with bind

**papayiya** · March 23rd, 2007

Hi,

Thank you for the tutorial, it worked great.
So now I have my

ns1.xxxx.com
ns2.xxxx.com

I want to set up another domain say abc.com to use my new DNS servers. I went through the process of registering the domain, setting the DNS servers to the above from GoDaddy, set up a new virtual host in apache, etc..

My quesiton is, how do I add another domain to my bind configuration?
I'd post what I did so far, but that might just confuse others.
Can you post a general example about what needs to be added in the bind?

Any help would be appreciated..
Thanks
George

I've experienced this intermittently. Most of the time I can ping internal hostnames, but sometimes, some of them just don't work. Then I'll come back later in the day and suddenly they do work.

This is the same basic problem as I'm having with resolving internal hostnames within Firefox on XP. Sometimes they work, sometimes they don't. If it doesn't work in Firefox, then ping will also be broken, so these issues share the same root cause.

Thank you phormion for the link to dig for Windows. Here's the output I see for dig and nslookup. I no longer get the timeout for nslookup (and I'm not sure how I fixed that), but the basic problem still remains.

Code:

dig zencartdemo.dev

; <<>> DiG 9.4.0 <<>> zencartdemo.dev

tomtom_in_eire great tutorial, worked well for me.

Hope you don't mind, I copied your post to the ubuntu wiki manual at http://http://ubuntuguide.org/wiki/U...IND_DNS_Server

I'm having a similar problem to CopaceticOpus. Name resolution works great when browsing locally from the bind server, but clients on the local network can rarely perform successful lookups. Sometimes it works, sometimes it doesn't. This is the case for both local and global DNS entries. It almost looks like a network connectivity issue, however communication via IP rather than DNS works great all the time. I've looked at my firewall logs (and disabled) - it doesn't seem to be an issue there. I can also consistently telnet into the bind port from a remote machine, even though the actual lookups fail with a timeout.

It was in fact a firewall problem. Everything is working well now...

**nasirazizawan** · May 3rd, 2007

hmmm .. all this is helpful .. but wot i was looking for is

i have a local network or more than 500 computers. working with out any domain or central control.

I am running a windows base DHCP to serve the IP address to clients. now i want to setup a dns server Ubuntu based , to keep track of the naming of all the computers.

regard,

nasir aziz awan.

Here's the forwarders part in named.conf:

Code:

forwarders {
  205.152.37.23;
  };

Any idea what I'm doing wrong? I'm trying to set up an DNS server that'll act as a local cache (Bellsouth's DNS kinda sucks) and so I set up a few internal websites and servers.

Coog

Well, firts of all

You should change the location of the option 'forwarders' into the file 'named.conf.options'
and remove it from the 'named.conf' file.

This because in the named.conf file there is an include section for the 'named.conf.options' file so maybe the problem is around there. And if there is not the include. here's an example:

Code:

include "/etc/bind/named.conf.options";

Hope it works. Any questions or corrections are welcome.

I tried to use this tutorial to build an internal (not internet exposed) dns server on fiesty ubunt-server and it's been a struggle. bind9 loads, but is not functional. The named-checkconf is spitting out all kinds of errors.

Code:

zone localhost/IN: loaded serial 1
zone 127.in-addr.arpa/IN: loaded serial 1
zone 0.in-addr.arpa/IN: loaded serial 1
zone 255.in-addr.arpa/IN: loaded serial 1
dns_rdata_fromtext: /etc/bind/zones/dthacker.org.db:6: near 'dthacker.org.': syntax error
zone dthacker.org/IN: loading master file /etc/bind/zones/dthacker.org.db: syntax error

dns_rdata_fromtext: /etc/bind/zones/rev.1.168.192.in-addr.arpa:6: near eol: unexpected end of input

/etc/bind/zones/rev.1.168.192.in-addr.arpa:10: no TTL specified; zone rejected
/etc/bind/zones/rev.1.168.192.in-addr.arpa:16: unknown RR type 'example.com'

_default/1.168.192.in-addr.arpa/IN: unexpected end of input

I don't understand why bind is complaining about TTL settings, none were specified in the tutorial. I also can't tell if semicolons are necessary, or just comment indicators. Here are my zone files.

Code:

dthacker.org.  IN SOA ns1.dthacker.org. (
                                  2007062602
                                  28800
                                  3600
                                  604800
                                  38400; )

dthacker.org.           IN NS ns1.dthacker.org.

ns1             IN  A  192.168.1.30
buckbeak        IN  A  192.168.1.5
fluffy          IN  A  192.168.1.3

Code:

@ IN SOA ns1.dthacker.org. (
                        2007062602;
                        28800;
                        604800;
                        604800;
                        86400
)

                     IN    NS     ns1.dthacker.org
30                    IN    PTR   dthacker.org

Any help would be appreciated. These eol errors are driving me nuts!

dthacker: I think your problem is the semicolon in this line:

38400; )

The semicolon is the start of a comment in these files, so everything after the semicolon on that line is ignored. This means your closing parentheses is not being recognized.
