+The 'linode' protocol is used by DNS services offered by www.linode.com. | |

+Configuration variables applicable to the 'linode' protocol are: | |
+ protocol=linode ## | |
+ server=fqdn.of.service ## defaults to api.linode.com | |
+ login=domain-id ## domain id from the service | |
+ password=linode-api-key ## api key from service account | |
+ resourceid ## id of the A record for the domain from the service | |
+ | |
+Example ${program}.conf file entries: | |
+ ## single host update | |

This patch was originally found here.
Hi David, thank you for the info. Since you have experience patching this part in the code, can you add the patch on the ddclient so that others can benefit, too, and you don't have to re-patch on every new release :)?
Hi @rfc4711,
Unfortunately I don't use this patch anymore (although I might use it in the future).
I've reapplied the patch to the latest upstream source, you can find it here: https://github.com/amoe/ddclient/tree/feature_provider_linode

Hi David, would it be possible to contribute your code also to the ddclient git repository?
