tinydyndns - configuration

Before starting the pop-before-dyndns service, you will make to have four decisions:

The pop-before-dyndns account name, normally tinydyn. The tinydns program runs under this account. If this account does not exist, create it now.
The DNS log account name, normally dnslog. Logging programs run under this account. If this account does not exist, create it now.
The domain name for the pop-before-dyndns service, say dyn.smarden.org.
The IP address the pop-before-dyndns service will use, say 5.6.7.8.

Create the tinydyndns service directories by running the tinydyndns-conf program.

 # tinydyndns-conf tinydyn dnslog /etc/tinydyn 5.6.7.8 dyn.smarden.org

Tell svscan about the new services:

 # ln -s /etc/tinydyn /service/
 # ln -s /etc/tinydyn/pop /service/tinydyn-pop

Wait five seconds for the services to start and check the logs:

 # less /service/tinydyn/log/main/current
 # less /service/tinydyn-pop/log/main/current

Now tell the pop-before-dyndns service about a dynamic hostname it should handle, say floyd:

 # su - tinydyn
 $ cd /etc/tinydyn/pop
 $ ./setpasswd floyd guest

Activate this hostname by connecting to the tinydyn-pop service as user floyd:

 $ telnet 5.6.7.8 110
 Trying 5.6.7.8...
 Connected to 5.6.7.8.
 Escape character is '^]'.
 +OK <8746.1015174596@dyn.smarden.org>
 USER floyd
 +OK
 PASS guest
 +OK
 QUIT
 Connection closed by foreign host.
 $

Check the tinydyn service for this dynamic hostname:

 $ dnsq a floyd.dyn.smarden.org 5.6.7.8

The output should show your system's IP address in the answer section.

To tell the tinydyn service about more dynamic hostnames, just run the setpasswd script as user tinydyn as shown above.

Finally, tell the administrator of smarden.org to delegate the domain dyn.smarden.org to the server a.ns.dyn.smarden.org running on IP address 5.6.7.8.
