Communicating to an external process running on the users desktop.Generating an error message to an email address configured by the user.Logging a message to a log window specific to the Dyn Update Client.Logging a message in the general log window for the router (assuming it has one).For this reason, any failed update attempt should cause the client to be disabled until the situation is corrected and the client is manually re-enabled by the user.Īdditionally, because the update may fail for a number of different reasons, the client needs to provide some method of communicating with the user that the update has failed and why. Fatal UpdatesĪny failed update attempt is fatal which means that all further updates will also fail until the user has taken some sort of corrective action. 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. Users should not be allowed to repeatedly force updates. This can be used to verify the authentication credentials and the current IP address.Īs this is fairly infrequent, repeated instances of nochg updates will result in the host being blocked. Users may also be given the option to “force” an update. The only acceptable situation where this allowed is during client initialization when the host has already been set to the same IP address. No Change UpdatesĪ nochg indicates a successful update but the IP address or other settings have not changed. Code good indicates that the update was successful and that the IP address was changed in our system. There is only one return code which indicates a successful update. Return codes indicating a failure with the account or the system are given only once. If updating multiple hostnames, hostname-specific return codes are given one per line, in the same order as the hostnames were specified. To make troubleshooting easier, generic error messages such as “Unable to update” should not be used. If there is an error, clients should communicate to the user a brief description of the problem that the return code indicates. When updating a hostname, the response to the update syntax will be one of the return codes.
