Redundant DNS with Linode API (plugin)

[croemmich]

I just finished writing a plugin for ISPConfig 3 that manages Linode slave DNS entries when SOAs are created, updated, or deleted. I thought it might be useful for someone out there, so here it is!

Who is it for?
Anyone with a Linode account. Likely more specifically, anyone with a single ISPConfig server running on a Linode VPS.

What's it do?
In a normal single server ISPConfig setup there is a single point of failure for DNS services. To solve this problem, the plugin creates slave zones on Linode's DNS servers using the Linode DNS API. The slave zones replicate the ISPConfig server's zone and respond to requests if the master is down.

You can grab the plugin here:

How about some installation guide or deployment via a repository?

Installation info is contained in the plugin file. I'll maybe set up a repo at some point. Not that useful for me really, as I only have one server, but I'll think about it.

I could host your files in my repo or you send the finished install field to Till for the official repo
