You should create a TSIG key, and configure the zones on the remote server to only accept dynamic DNS updates signed by this key. And then use this key with nsupdate when sending your updates. Check the man page of nsupdate and look at the '-k' and '-y' options for using tsig keys. You can additionally also configure your remote BIND to accept updates only from certain IP addresses. For details on how to configure this, please read the excellent documentation (especially section 4.2.29 and the "allow-update" option): https://bind9.readthedocs.io/en/v9_16/ Regards, Anand Buddhdev _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
