x2go.checkhosts.X2GoInteractiveAddPolicy

Class X2GoInteractiveAddPolicy

object --+ | paramiko.MissingHostKeyPolicy --+ | X2GoMissingHostKeyPolicy --+ | X2GoInteractiveAddPolicy

Policy for making host key information available to Python X2Go after a Paramiko/SSH connect has been attempted. This class needs information about the associated X2GoSession instance.

Once called, the missing_host_key method of this class will try to call X2GoSession.HOOK_check_host_dialog(). This hook method---if not re-defined in your application---will then try to call the X2GoClient.HOOK_check_host_dialog(), which then will return True by default if not customized in your application.

To accept host key checks, make sure to either customize the X2GoClient.HOOK_check_host_dialog() method or the X2GoSession.HOOK_check_host_dialog() method and hook some interactive user dialog to either of them.
