The 'dnsexit' protocol is the protocol used by the dynamic hostname services
|
||||
of the 'DnsExit' dns services. This is currently used by the free
|
||||
dynamic DNS service offered by www.dnsexit.com.
|
||||
|
||||
Configuration variables applicable to the 'dnsexit' protocol are:
|
||||
ssl=no ## turn off ssl
|
||||
protocol=dnsexit ##
|
||||
server=update.dnsexit.com ## defaults to update.dnsexit.com
|
||||
use=web ## defaults to web
|
||||
web=update.dnsexit.com ## defaults to update.dnsexit.com
|
||||
script=/RemoteUpdate.sv ## defaults to /RemoteUpdate.sv
|
||||
login=service-userid ## userid registered with the service
|
||||
password=service-password ## password registered with the service
|
||||
fully.qualified.host ## the host registered with the service.
|
||||
|
||||
Example ${program}.conf file entries:
|
||||
## single host update
|
||||
protocol=dnsexit \\
|
||||
login=service-userid \\
|
||||
password=service-password \\
