README for ddclient-curl scripts
================================

1. What is ddclient-curl?
-------------------------

It's a couple of very lightweight scripts to simply do the following:

* Get your public IP address, using a web service (from a specified interface, e.g. tun0)
* Update your Dynamic DNS provider with your new public IP address
* Support multiple hosts/updates for the same IP

2. What's in the box?
---------------------

Two bash scripts:

* ddclientcurl.sh
* ddall.sh

3. Dependencies
---------------

They need the following:

* Linux environment running bash (e.g. Debian/Ubuntu/Mint)
* curl
* grep
* a hostname registered with no-ip.org

Usually, you can install curl and grep by typing:   apt-get install curl grep

4. Installation
---------------

* Put both files in a directory wherever you like
* Edit ddall.sh (e.g. nano ddall.sh), set the properties for:
  - DDCLIENT_SH location (where you put the scripts)
  - EXT_NIC (the interface you want to check the public IP for)
  - DNS_NAME (the hostname you registered with no-ip.org)
  - USERNAME (the username for your account with no-ip.org)
  - PASSWORD (the password for your account with no-ip.org)
* Edit ddclientcurl.sh (e.g. nano ddclientcurl.sh), set the properties for:
  - DDCLIENTCURL_LOG (where you like to log)
  - Under "Update Dyn DNS Clients", copy the curl invocation line for any other hostnames you wish to update for the same public IP address

5. Usage
--------

* Call ddall.sh manually, OR
* Call ddall.sh from an up script, e.g. under OpenVPN from up.sh, OR
* Call ddall.sh from a cron job run on a schedule, OR
* Call however you like :)

6. Warranty
-----------

None whatsoever!
