Web service for Dynamic DNS service

Last in my small series about running your own Dynamic DNS service: how to support clients which can’t use the nsupdate tool directly.


What is my IP address?

For a number of reasons it is nice to know your own IP-address. If you are behind a firewall or a NAT system, you usually only have a private IP-address and “someone else” on the internet needs to tell you your official IP-address.

Manage Serendipity installations with Spartacus

I have to manage a few Serendipity (s9y) installations. Only one of them is my personal blog, the others are customer installations, all on different servers.

Stupid open_basedir handling in PHP

No problem - or?

BOOLEAN datatype with PHP-compatible output

UBERWACH plugin for serendipity

Maybe you already noted the small surveillance camera in the menu list on the right side. Hopefully the icon is green, that would be good for you. If it’s red your request comes from an IP-address known for being allocated by a German ministry or political party. Thats nice to know, isn’t it?
