# Use a TSIG-signed DDNS update to update our hostname-to-address
# mapping.
#
# usage: ddns.py <ip-address>
#
# On linux systems, you can automatically update your DNS any time an
# interface comes up by adding an ifup-local script that invokes this
# python code.
#
# E.g. on my systems I have this
#
#        #!/bin/sh
#
#        DEVICE=$1
#
#        if [ "X${DEVICE}" == "Xeth0" ]; then
#                IPADDR=`LANG= LC_ALL= ifconfig ${DEVICE} | grep 'inet addr' |
#                        awk -F: '{ print $2 } ' | awk '{ print $1 }'`
#                /usr/local/sbin/ddns.py $IPADDR
#        fi
#
# in /etc/ifup-local.
