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.
