DtDNS - Introduction The majority of domestic Internet connections are via a dynamic IP address, one that can change every time you connect to the Internet. A web server requires a static IP address. A free dynamic DNS service such as DtDNS provides accounts and tracking software to automatically update your IP address when it changes, creating the effect of a static IP address. The Uniform Server has a built-in utility which supports the DtDNS service. This page covers the configuration sub-menu, which allows you to configure and test the DtDNS service.

Enable in CRON

Every time you start your PC and reconnect to the Internet (given a new IP address) you need to manually run the DtDNS updater.

Remembering to manually run scripts like DtDNS becomes a chore. Uniform Server centralises running this type of script using portable Cron. Cron is started either manually (portable) or run as a service. It periodically executes a list of scripts; the DtDNS script is included and requires enabling as follows:

Server Configuration > DtDNS > Enable in CRON Opens Cron configuration file in Notepad Locate section shown on right	;[dtdns] ;start = 2011-04-7 13:20:00 ;period = 600  ; 10 Mins as required by DtDNS ;path = C:\UniServer\uni_con\dtdns_updater\Run_dtdns_updater.bat ;ref =
Enable pre-configured DtDNS section in Cron as follows: Un-comment four lines as shown on right.	;[dtdns] start = 2011-04-7 13:20:00 period = 600  ; 10 Mins as required by DtDNS path = C:\UniServer\uni_con\dtdns_updater\Run_dtdns_updater.bat ref =

Note: You can change the start time and period to suite your own requirements see Cron Configuration file for details.
