# This script allows you to quickly change your bind9 configuration:
#     - define an internal domain and bind it to 127.0.0.1
#     - add SRV records to use this domain with your local XMPP server
#
# It will mess up your actual bind9 configuration. It should not be used on
# production servers but only on your development machine with local servers.
# USE AT YOUR OWN RISK! Be sure to BACKUP /etc/bind and /var/cache/bind before!
#
# Configuration files based on:
#     - http://www.madboa.com/geek/soho-bind
#     - http://wiki.xmpp.org/web/SRV_Records
#     - http://prosody.im/doc/dns
#
# For this to work, Prosody configuration must define the domain as a VirtualHost.
# It is also assumed that the Prosody "directory" option is set to "/var/cache/bind".
#
# Finally, you may want to modify your SàT configuration file to set the option
# "new_account_domain" to that domain passed in $1 in order to register new
# account from Libervia, and the "jid" option of sat_pubsub should be set to
# "sat-pubsub.<domain>" for the (micro)blogging feature to work.
#
# You can also check this page with additional information about how to restore
# your previously configured domains (if any...) after having ran the script:
# http://wiki.goffi.org/wiki/How_to_change_your_Libervia%27s_domain_name/en
