ddclient - DNS record updating

Use this contrib when you have a sme server connected to a ISP service using a dynamic IP, and you wish to host multiple domains.

ddclient is a client for updating dynamic DNS entries for domains hosted at different DNS providers.

Configure your dynamic host domains via the ddclient server manager panel.

ddclient can be used on servers configured in server gateway mode or in server only mode.

Smecontribs repository version

Maintainer

Stéphane de Labrusse AKA Stephdl

This contrib is the official and maintained version for SME Server 8, some Free or paid services of dynamic dns had been incorporated to the contribs.

Installation

yum install --enablerepo=smecontribs smeserver-ddclient

then

signal-event ddclient

or

signal-event post-upgrade; signal-event reboot

A new panel will be added to the server manager.

Use this panel to configure domain records you wish to keep updated with your dynamic IP using the ddclient contrib

How to use

First you need to create a domain in the server-manager (domains panel) which must match the domain you set with your dynamic dns provider.

For example if the domain you made at DTdns is :

home.dtdns.net 

You have to create a relevant domain with this name.

Then go to the panel of "Dynamic clients", choose the domain you made then set your dynamic DNS provider eg (dtdns) and credentials associated that provider.

Every 300s the contrib perform a check to verify if your ip has been changed to http://checkip.dyndns.org/. Do not try to decrease the time-out under of 300s else you could be blacklisted by providers

There are some of the services that you can use

• ip.changeip.com
• ipdetect.dnspark.com
• checkip.dyndns.org:8245
• checkip.dyndns.org

If you want to change the service which verifies your external ip you can do :

config setprop ddclient urlcheckip ip.changeip.com
signal-event ddclient

smeserver.free.fr version

	Note:
	This contribs is no longer maintained and may be unstable or broke your system

	Warning:
	When you have the smeserver.free.fr sme7-ddclient contrib installed and you run yum upgrade with the smecontribs repository enabled on your server, watch out! There is a smeserver-ddclient package that will get installed as an upgrade and this conflicts with the sme7-ddclient package ! Remove the sme7-ddclient first, see instructions below.

Note: This RPM works with SME 8 or SME 7

The smeserver.free.fr site appears to be defunct (since at least April 2012), so this article provides a link to the contrib at another external file download site.

This contrib has some additional features like the ability to select the method on how the detect the external IP address and the ability to publish arbitrary domain names (i.e. not just the ones that are on your server).

Installation

Download the latest rpm version from

http://www.files.com/shared/4f89e32b9c187/sme7-ddclient-3.7.3-7.noarch.zip

to an empty folder eg /tmp and unzip the file

unzip sme7-ddclient*

The currently available rpm is:

sme7-ddclient-3.7.3-7.noarch.rpm

Then cd to that folder and install the rpm (change the rpm name in the following command to match the latest available version)

cd /tmp
yum localinstall sme7-ddclient*.rpm

Removal

yum remove sme7-ddclient
signal-event post-upgrade;signal-event reboot

Using SME default dynamic client & external DNS CNAME entries

In many cases, you really do not need to use ddclient or some variation of it eg sme7-ddclient or smeserver-ddclient

You can use the built in dynamic client for your main domain (accessible by running Configure this server from the admin console).

Then create CNAME entries in external DNS records which point at the main domain name.

SME will update the main domain name/dynamicIP change, and the additional domains will follow it as the external IP changes.

The use of this method is only possible where the full DNS records are accessible & editable by admin users.

In some situations with DNS service providers, these DNS records are not accessible, in that case you will need to use one of the ddclient methods.

Also see http://bugs.contribs.org/show_bug.cgi?id=6206#c9 which says:

"I notice that you mention two dyndns domains, but you should be able to set up domain2.x.y to be a CNAME for domain1.x.y, then configure domain1.x.y with the builtin client."
