#################################################################
|
||||
# In order to enable dynamic dns you need at least one section,
|
||||
# and in that seciton the "enabled" option must be set to one
|
||||
#
|
||||
# Each section represents an update to a different service
|
||||
#
|
||||
# You specify your domain name, your username and your password
|
||||
# with the optins "domain", "username" and "password" respectively
|
||||
#
|
||||
# Next you need to specify the name of the service you are
|
||||
# connecting to "eg. dyndns.org". The format of the update
|
||||
# urls for several different dynamic dns services is specified
|
||||
# in the /usr/lib/ddns/services file. This list is hardly complete
|
||||
# as there are many, many different dynamic dns services. If your
|
||||
# service is on the list you can merely specify it with the
|
||||
# "service_name" option. Otherwise you will need to determine
|
||||
# the format of the url to update with. You can either add an
|
||||
# entry to the /usr/lib/ddns/services file or specify this with
|
||||
# the "update_url" option.
|
||||
#
|
||||
# We also need to specify the source of the ip address to associate with
|
||||
# your domain. The "ip_source" option can be "network", "interface"
|
||||
# or "web", with "network" as the default.
|
||||
#
|
||||
# If "ip_source" is "network" you specify a network section in your
|
||||
# /etc/network config file (e.g. "wan", which is the default) with
|
||||
# the "ip_network" option. If you specify "wan", you will update
|
||||
# with whatever the ip for your wan is.
|
||||
#
|
||||
# If "ip_source" is "interface" you specify a hardware interface
|
||||
# (e.g. "eth1") and whatever the current ip of this interface is
|
||||
# will be associated with the domain when an update is performed.
|
||||
#
|
||||
# If "ip_source" is "script" you specify a script to obtain ip address.
|
||||
# The "ip_script" option should contain path to your script.
|
||||
#
|
||||
# The last possibility is that "ip_source" is "web", which means
|
||||
# that in order to obtain our ip address we will connect to a
|
||||
# website, and the first valid ip address listed on that page
|
||||
# will be assumed to be ours. If you are behind another firewall
|
||||
# this is the best option since none of the local networks or
|
||||
# interfaces will have the external ip. The website to connect
|
||||
# to is specified by the "ip_url" option. You may specify multiple
|
||||
# urls in the option, separated by whitespace.
|
||||
#
|
||||
# Finally we need to specify how often to check whether we need
|
||||
# to check whether the ip address has changed (and if so update
|
||||
# it) and how often we need to force an update ( many services
|
||||
# will expire your domain if you don't connect and do an update
|
||||
# every so often). Use the "check_interval" to specify how
|
||||
# often to check whether an update is necessary, the "retry_interval"
|
||||
# to specify how often to retry in case the update has failed, and
|
||||
# the "force_interval" option to specify how often to force an
|
||||
# update. Specify the units for these values with the "check_unit",
|
||||
# the "retry_init" and the "force_unit" options. Units can be
|
||||
# "days", "hours", "minutes" or "seconds". The default force_unit
|
||||
# is hours, the default retry_unit is seconds and the default
|
||||
# check_unit is seconds. The default check_interval is 600 seconds,
|
||||
# or ten minutes. The default retry_interval is 60 seconds, or one
|
||||
# minute. The default force_interval is 72 hours or 3 days.

# This file contains the update urls for various dynamic dns services.

# Column one contains the service name, column two contains the update url.
|
||||
# within the update url there are 4 variables you can use: [USERNAME],
|
||||
# [PASSWORD], [DOMAIN] and [IP]. These are substituted for the username,
|
||||
# password, and domain name specified in the /etc/config/ddns file when an
|
||||
# update is performed. The IP is substituted for the current ip address of the
|
||||
# router. These variables are case sensitive, while urls generally are not, so
|
||||
# if you need to enter the same text in the url (which seems very unlikely) put
|
||||
# that text in lowercase, while the variables should remain in uppercase
