Ddclient
Version
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 8,9 and 10. Note that some free and paid dynamic dns services have been incorporated into the contrib.
Installation
yum install --enablerepo=smecontribs smeserver-ddclient
then
signal-event ddclient
or
signal-event post-upgrade; signal-event reboot
yum install --enablerepo=smecontribs smeserver-ddclient
then
signal-event ddclient
or
signal-event post-upgrade; signal-event reboot
yum install --enablerepo=smecontribs smeserver-ddclient ddclient
then
signal-event smeserver-ddclient-update
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 associated credentials to 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
- checkip.amazonaws.com
If you want to change the service which verifies your external ip you can do :
config setprop ddclient urlcheckip ip.changeip.com signal-event smeserver-ddclient-update
- 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 smeserver-ddclient-update
- use SSL
since ddclient 3.7.0 you can encrypt transactions to avoid clear messages. by default forced to yes
config setprop ddclient SSL yes
or
config setprop ddclient SSL no
then
signal-event smeserver-ddclient-update
- Controlling email notifications
- DB entries are: mailSuccess and mailFailure
- default behaviour: If the keys are not set then they default to admin
config setprop ddclient mailSuccess '' or 'none'
Output:
mail=
config setprop ddclient mailFailure '' or 'none'
Output:
mail-failure=
config setprop ddclient mailSuccess someaddress@yahoo.com
Output:
mail=someaddress@yahoo.com
config setprop ddclient mailFailure somewhereelse@gmail.com
Output:
mail-failure=somewhereelse@gmail.com
Remove the keys to reset to the default 'admin'
config delkey ddclient mailSuccess config delkey ddclient mailFailure
- full db ddclient
ddclient=service DeamonUpdate=1800 Extinterface= ForceIP= SSL=yes cmd= debug=enabled method=web quiet=disabled status=enabled syslog=enabled urlcheckip=https://checkip.amazonaws.com/ verbose=enabled mailSuccess | unset default=admin mailFailure | unset default=admin
- method
this will allow you to set the way you retrieve the new IP. By default this use the web request to an external url, which you can set. THis would work for all server, even if not gateway. However you can get many timeout depending of the website you try to reach to get the IP.
available methods :
- smeIF : will get IP from external interface. BEST choice if your SME act as gateway.
- smeCMD : will get the IP from the configuration DB : /sbin/e-smith/db configuration getprop ExternalInterface IPAddress
- web : will get the ip from webpage at the URL in property 'urlcheckip' and use the filter from property 'webskip'
- if : will get the IP from the network interface which name is in property 'Extinterface'
- ip : will manually force the ip in property 'ForceIP'
- cmd : will call the script in property 'cmd' and use the filter in the property 'cmdskip' to get the IP
- 'CUSTOM' : replace CUSTOM by one of the accepted value of the ddclient command for use option. Yo also have to fill the property 'fwaddress' which is the gateway address, and could also fill the properties 'fwlogin', 'fwpassword' and 'fwskip'

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
yum remove smeserver-ddclient signal-event post-upgrade; signal-event reboot
Debug
For debug mode you may need per-JSON-Any
To install that you will need the EPEL repo: https://wiki.contribs.org/Epel
Then
yum --enablerepo=epel install perl-JSON-Any
- You can keep an eye on log
watch 'cat /var/log/messages|grep SUCCESS'
- You can supervise dns record
watch 'dig any your_dynamic_dns_host.xxx @dns_server_of_your_dynamic_dns_provider'
- If you want to know the dns servers of your dynamic provider, do
dig any your_dynamic_dns_host.xxx
and look about hosts in NS columns.
- If stuff goes bad you can debug and see what is happening to the deamon
ddclient -daemon=0 -debug -verbose -noquiet
and report please
- keep an eye on the ddclient cache
less /var/cache/ddclient/ddclient.cache

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."
