ddns

ddns is a PHP script allowing for updates to DNS records. This allows you to run your own dynamic DNS update system similar to public ones like dyndns.com, noip.com, etc. The API is based on the one provided by dyndns.com itself, so it should be compatible with most clients out there.

KISS ... intended for small installations ...

PREREQUISITES

Run own nameserver, i.e. be in control of your zones.

API

Parameters:

  • myip
  • hostname
  • ...

THEORY OF OPERATION

After some basic option and argument parsing, otca sets up a suitable temporary environment for the ca(1) command. It then generates and self-signs a certificate for the CA, handing over the appropriate options. Afterwards a [certificate signing request][csr] for the server and client is generated using OpenSSL's req(1) command. These CSRs are then signed by the previously created CA using the ca(1) command once more. After some conversions (see pkcs12(1)), the certificates and keys are moved into the specified output directory. Then the temporary scratch space is removed, including the CA's private key. This, in essence, renders the CA useless, which is the point of this concept.

IP detection as described on SPDNS ...
