Updating zserver dyndns info nohost the hostname

To make troubleshooting easier, generic error messages such as “Unable to update” should not be used.

If updating multiple hostnames, hostname-specific return codes are given one per line, in the same order as the hostnames were specified.

Dyn will pass back a return code that the client needs to parse. If you have questions about the syntax, please contact Dyn support. It is not necessary to open any incoming ports (or allow incoming ICMP) for updating.

All clients must send a well-formed user agent that includes company name, model number, and software build revision.

If the IP address passed to the system is not properly formed, it will be ignored and the system’s best guess will be used.

While it is not expected that the clients will prevent users from doing this, the client itself should strenuously avoid performing updates which would result in this return result.

Any failed update attempt is fatal which means that all further updates will also fail until the user has taken some sort of corrective action.

Users may also be given the option to “force” an update.

This can be used to verify the authentication credentials and the current IP address.

The client must stop updating that hostname until the user confirms that the problem has been resolved.
