== CONFIGURING ${program}
|
|
|
|
The configuration file, ${program}.conf, can be used to define the
|
|
default behaviour and operation of ${program}. The file consists of
|
|
sequences of global variable definitions and host definitions.
|
|
|
|
Global definitions look like:
|
|
name=value [,name=value]*
|
|
|
|
For example:
|
|
daemon=5m
|
|
use=if, if=eth0
|
|
proxy=proxy.myisp.com
|
|
protocol=dyndns2
|
|
|
|
specifies that ${program} should operate as a daemon, checking the
|
|
eth0 interface for an IP address change every 5 minutes and use the
|
|
'dyndns2' protocol by default.
|
|
|
|
Host definitions look like:
|
|
[name=value [,name=value]*]* a.host.domain [,b.host.domain] [login] [password]
|
|
|
|
For example:
|
|
protocol=hammernode1, \\
|
|
login=my-hn-login, password=my-hn-password myhost.hn.org
|
|
login=my-login, password=my-password myhost.dyndns.org,my2nd.dyndns.org
|
|
|
|
specifies two host definitions.
|
|
|
|
The first definition will use the hammernode1 protocol,
|
|
my-hn-login and my-hn-password to update the ip-address of
|
|
myhost.hn.org and my2ndhost.hn.org.
|
|
|
|
The second host definition will use the current default protocol
|
|
('dyndns2'), my-login and my-password to update the ip-address of
|
|
myhost.dyndns.org and my2ndhost.dyndns.org.
|
|
|
|
The order of this sequence is significant because the values of any
|
|
global variable definitions are bound to a host definition when the
|
|
host definition is encountered.
|
|
|
|
See the sample-${program}.conf file for further examples.

The 'dyndns1' protocol is a deprecated protocol used by the free dynamic

|
DNS service offered by www.dyndns.org. The 'dyndns2' should be used to
|
|
update the www.dyndns.org service. However, other services are also
|
|
using this protocol so support is still provided by ${program}.
|
|
|

Configuration variables applicable to the 'dyndns1' protocol are:
|
|
protocol=dyndns1 ##
|
|
server=fqdn.of.service ## defaults to members.dyndns.org
|
|
backupmx=no|yes ## indicates that this host is the primary MX for the domain.
|
|
mx=any.host.domain ## a host MX'ing for this host definition.
|
|
wildcard=no|yes ## add a DNS wildcard CNAME record that points to {host}
|
|
login=service-login ## login name and password registered with the service
|
|
password=service-password ##
|
|
fully.qualified.host ## the host registered with the service.
