#! /bin/sh

# This is a sample global plug-in for ifcfg.def script.
# It will update ooo.dhs.org where ooo is the user_id.
# To enable a hostname update to ooo.dhs.org simply create
# the file INTERFACE.dhs-update with the lines:
# 
# user_id="Your account name at dhs.org"
# password="Your password at dhs.org"
#
# You may specify the following as well
# DHS_HOSTNAME="Your hostname on dhs"    #default is one received by DHCPXD
# DHS_DOMAIN="The domain on dhs"         #default is dhs.org itself
# DHS_TYPE="dynamic|static"              #default is static
# DHS_WILDCARD=y|n                       #default is y
# DHS_MX="netname-for-your-mail.com"     #default is none
#
# Big thanks to Tarb for this script.
