OpenView NNM ovwdb Daemon
Port 2447 is commonly associated with Hewlett-Packard's OpenView Network Node Manager (NNM), a widely used solution for network monitoring, fault detection, and management. Specifically, this port is used by 'ovwdb,' the OpenView object database daemon, facilitating inter-component communication and database access within NNM's distributed architecture. It typically listens over both TCP and UDP, enabling efficient data handling between consoles and agents on large enterprise networks..
HP OpenView Network Node Manager (NNM) is a comprehensive network management platform designed to provide real-time monitoring, topology discovery, event correlation, and root cause analysis across complex networking environments. The 'ovwdb' daemon functions as the network's object database service, managing persistent storage of network topology, status information, and device inventory data. Port 2447 acts as a critical communication endpoint for components querying or updating this database.
Communication over port 2447 can occur using both TCP and UDP protocols. TCP facilitates reliable, session-oriented transactions such as topology updates, while UDP allows for lightweight, rapid notifications or status checks. The daemon exposes APIs for internal modules, management consoles, and sometimes external integration services, necessitating careful access control.
Given the nature of NNM, traffic on port 2447 is generally confined to trusted network segments or management VLANs. Proper network segmentation ensures that these sensitive services are insulated from untrusted or general-use parts of the network, maintaining the integrity and confidentiality of management communication.
