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
- For SME8
yum install --enablerepo=smecontribs smeserver-ddclient
then
signal-event ddclient
or
signal-event post-upgrade; signal-event reboot
You have to enable the stephdl and epel repositories.
yum install --enablerepo=stephdl,epel smeserver-ddclient signal-event ddclient
or
signal-event post-upgrade; signal-event reboot
- For SME9
You have to enable the stephdl and epel repositories.
yum install --enablerepo=stephdl,epel 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.
DB settings
- There are some of the services that you can use to detect your external ip
- 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
- Every 300s the contrib perform a check to verify if your ip has been changed to http://checkip.dyndns.org/. you can change the interval of the deamon update by a db command (by default it is 300 seconds). It seems that the minimum accepted is 60s. Possibly you could be blacklisted by providers if you decrease the time-out under of 300s.
config setprop ddclient DeamonUpdate 60 signal-event ddclient
- full db ddclient
# config show ddclient ddclient=service DeamonUpdate=300 status=enabled urlcheckip=checkip.dyndns.org

If your dynamic dns provider is not available in smeserver-ddclient, please raise a bug and provide the settings for your provider with ddclient (search for settings with google).
Removal

Debug
If stuff goes bad you can debug
ddclient -daemon=0 -debug -verbose -noquiet
and report please
Bugs
Please raise bugs under the SME-Contribs section in bugzilla and select the smeserver-ddclient component or use this link .
smeserver.free.fr version
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."
