The 'godaddy' protocol is used by DNS service offered by https://www.godaddy.com/domains.
|
||||
|
||||
Configuration variables applicable to the 'godaddy' protocol are:
|
||||
protocol=godaddy ##
|
||||
login=my-generated-token ## the token/key name provided by the API interface
|
||||
password=my-generated-secret ## the secret provided by the API interface
|
||||
zone=domain.tld ## the domain used for DNS update.
|
||||
ttl=600 ## time to live of the record;
|
||||
hostname.domain.tld ## hostname/subdomain
|
||||
|
||||
Example ${program}.conf file entries:
|
||||
## single host update
|
||||
protocol=godaddy \\
|
||||
login=my-generated-token \\
|
||||
password=my-generated-secret \\
|
||||
zone=example.com \\
|
||||
hostname.example.com
|
||||
|
||||
## multiple host update to the DNS service
|
||||
protocol=godaddy \\
|
||||
login=my-generated-token \\
|
||||
password=my-generated-secret \\
|
||||
zone=example.com \\
|
