Lotus Notes RPC
Port 1352 is primarily used for IBM Lotus Notes and Domino servers to communicate using a proprietary Remote Procedure Call (RPC) protocol. This protocol facilitates messaging, database, and directory services within the IBM collaboration suite, ensuring clients and servers exchange commands and data efficiently across networks..
Overview
IBM Lotus Notes and Domino rely on port 1352 to establish remote procedure call (RPC) sessions between clients, application servers, and database services. This protocol enables real-time collaboration features, including email, calendar management, and directory lookups by transmitting commands and data objects across distributed systems.
RPC Functionality
The Domino RPC protocol is proprietary, facilitating tightly integrated communication that allows Lotus Notes clients to access mail databases, replicate data, query directories, and perform administrative actions. It supports session management features such as authentication exchanges, transaction controls, and command queuing, all over a session-oriented transport like TCP.
Protocol Details
Typically utilizing TCP, the protocol handles various Notes client operations including opening mailboxes, directory lookups, or database replication. Given its proprietary nature, detailed protocol specifications are limited publicly. The communications are generally not encrypted unless additional security layers are implemented through Domino configuration or network-level protections such as VPNs.
