pyafraid is a command-line tool for updating IP addresses for the afraid.org DDNS service.

pyafraid can be installed using the standard easy_install command:

$ [sudo] easy_install pyafraid

Alternatively, you can install from a local version using setup.py install:

$ [sudo] python setup.py install

Once installed, simply run:

$ pyafraid update|query <username> -p <password> -n <hostname>

Or, if you'd like to use the SHA-1 hash instead of the username/password combo:

$ pyafraid update|query -s <sha_hash> -n <hostname>

For a more detailed usage description, use the --help/-h option:

$ pyafraid -h
Usage: pyafraid.py update|query [-h] [-u <username>] [-p <password>] [-n
<hostname>]


Options:
 -h, --help            show this help message and exit
 -u USERNAME, --username=USERNAME
                       The freedns.afraid.org username
 -p PASSWORD, --password=PASSWORD
                       The associated password
 -n HOSTNAME, --hostname=HOSTNAME
                       The name of the host to update or query
 -s SHA_HASH, --sha-hash=SHA_HASH
                       The SHA-1 hash from the API interface
                       URL. Don't use this with the -u and -p options.

For example, to update freedns.afraid.org to point to the current IP address, use the update argument:

$ pyafraid update -u myuser -p mypass -n mythbox.example.org
  Attempting to update mythbox.example.org...
  response from server:
  ERROR: Address 1.1.1.1 has not changed.

To query freedns.afraid.org for information about an account, you can use the query argument:

$ pyafraid query -u myuser -p mypass

 url:    http://freedns.afraid.org/dynamic/update.php?<some_hash>
 ip:     1.1.1.1
 desc:   example.org

 url:    http://freedns.afraid.org/dynamic/update.php?<some_other_hash>
 ip:     2.2.2.2
 desc:   deathstar.example.org

Note that specifying -n/--hostname will restrict the output to the given host.

pyafraid has only been actively tested on python 2.6, but should work with minor changes on python 2.2+. Patches are welcomed :)

In order to execute unit tests (using python setup.py test) the following modules are required:

• unittest2
• mock

All of these modules can be installed with easy_install:

$ [sudo] easy_install mock unittest2
