FreeBSD Configure DJBDNS TinyDNS Server

Author: Vivek Gite Last updated: July 8, 2009 5 comments

How do I configure tinydns a database-driven dns server under FreeBSD operating systems?

You need to create three user accounts under FreeBSD and add all of them to a group. This can be done using pw command as follows:

Step#1: Create DJBDNS Server Group

Type the following command:
# pw groupadd dnsusers

Step#2: Create TinyDNS Server User

Type the following command:
# pw useradd tinydns -s /bin/nologin -G dnsusers

Step#3: Create AxfrDNS Server User

Type the following command:
# pw useradd dnslog -s /bin/nologin -G dnsusers

Step#4: Create DJNDNS Server Log User

Type the following command:
# pw useradd axfrdns -s /bin/nologin -G dnsusers

Step#5: Create /var/service directory

Type the following command:
# mkdir /var/service/

Step#6: Turn On daemontools (svscan) Service

Type the following command:
# echo 'svscan_enable="YES"' >> /etc/rc.conf # /usr/local/etc/rc.d/svscan.sh start
Now, your server is ready to use. All you have to do is create zone for ns1.nixcraft.in.

I am running FreeBSD 8 and have followed the first page. On the last step, I do as prompted:

[root@vps ~]# echo ‘svscan_enable=”YES”‘ >> /etc/rc.conf
[root@vps ~]# /usr/local/etc/rc.d/svscan.sh start
bash: /usr/local/etc/rc.d/svscan.sh: No such file or directory

Svscan exists though:
[root@vps ~]# whereis svscan
svscan: /usr/local/bin/svscan /usr/local/man/man8/svscan.8.gz

Running Svscan:
[root@vps ~]# /usr/local/bin/svscan
supervise: fatal: unable to start namedb/run: file does not exist

Is there any solution?

I’m runing FreeBSD 10.1-RELEASE.

Below, I am using the IP address of my VPS — 80.240.140.221. If you are looking at my comment trying to set it up for yourself, you will of course need to replace my IP with yours.

I did the same as shown here up until the end, except at the end, instead of

# /usr/local/etc/rc.d/svscan.sh start

I did

# service svscan start

Then, furthermore, I did:

# tinydns-conf tinydns dnslog /usr/local/etc/tinydns 80.240.140.221
# ln -s /usr/local/etc/tinydns /var/service/

Confirmed that it’s running:

$ sockstat -l | grep :53
tinydns  tinydns    761   3  udp4   80.240.140.221:53     *:*

Is it working?

$ drill erikano.net @80.240.140.221
Error: error sending query: Could not send or receive, because of network error

What does the log say?

$ cat /var/service/tinydns/log/main/current

It’s receiving requests. Good. Probably the reason why it’s not responding is because there is more configuration to be done.

Hopefully, http://cr.yp.to/djbdns/run-server.html and http://tinydns.org/ covers the remainder of the configuration that needs to be done.

Indeed, http://cr.yp.to/djbdns/run-server.html provides what is needed for a basic configuration.

# cd /var/service/tinydns/root/
# ./add-ns inbound.mx 80.240.140.221
# ./add-ns erikano.net 80.240.140.221
# ./add-host quattuor.inbound.mx 80.240.140.221
# ./add-alias erikano.net 80.240.140.221 
# ./add-alias www.erikano.net 80.240.140.221
# make

I haven’t made the VPS authorative of the domains for real yet, not sure if/when I will, but here we see it working from my Ubuntu-running desktop querying the FreeBSD VPS:
