RFCd

RFCd is a daemon process that manages remote file access on Unix-like operating systems. It is part of the Network File System (NFS) suite of tools, which allows computers to share files and directories over a network. RFCd specifically handles the RPC (Remote Procedure Call) protocol, which is used by NFS to communicate between clients and servers. When a client requests access to a file on an NFS server, RFCd on the server facilitates the communication by handling the RPC requests and responses. This enables seamless file sharing across different machines, making it a fundamental component for distributed file systems. The daemon typically runs in the background and listens for incoming RPC requests. Its presence is crucial for the proper functioning of NFS, ensuring that clients can mount and interact with remote file systems as if they were local. Without RFCd, NFS would not be able to establish the necessary communication channels to perform file operations.
