Dell OpenManage
Dell OpenManage HTTPS service listens on port 1311 to provide administrators with secure access to Dell servers' management consoles. It utilizes HTTPS encryption to ensure communication confidentiality and typically facilitates hardware monitoring, firmware updates, status alerts, and remote server administration via a web interface. This port is essential for managing Dell PowerEdge servers using Dell OpenManage Server Administrator (OMSA)..
Port 1311 supports the Dell OpenManage Server Administrator (OMSA) tool over HTTPS. Dell OMSA is a systems management solution enabling administrators to monitor, manage, update, and troubleshoot Dell servers both locally and remotely. Using a web browser, IT personnel can securely view hardware status, perform diagnostics, manage storage arrays, configure alerts, and initiate updates.
Communication over this port uses the HTTPS protocol (HTTP over SSL/TLS), ensuring that sensitive server management data is encrypted end-to-end between client browser and server. It typically runs on the Dell server's integrated management interface, often listening exclusively on this port unless reconfigured.
OMSA's web server component, accessible on 1311/tcp, is platform-specific but includes standard SSL/TLS handshake cryptography, typical REST API-like calls, and a graphical user interface. Dell recommends using strong encryption and limiting access to trusted hosts on management networks only.
