с помощью (windows) PowerShell для выполнения динамического обновления DNS с TSIG для сервер BIND9

Им нужно будет загрузить nsupdate из BIND ( https://www.isc.org/downloads/ ). Можно вызвать nsupdate с хоста PowerShell.

Вот сценарий, который будет создавать и отправлять запросы DDNS, если предоставляется файл tsig. Убедитесь, что разрешения NTFS установлены для предотвращения доступа неавторизованных пользователей (включая других администраторов) к этому файлу.

Это предполагает, что вы установили nsupdate.exe и связанные с ним dll в C: \ windows \ system32, но его можно изменить для других путей.

Я приветствую любые запросы на вытягивание. https://github.com/ACiDGRiM/UsefulScripts/blob/master/Update-DNS.ps1
