UNIX domain sockets are a technology for interprocess communication on a single computer.

UNIX domain sockets are a technology for interprocess communication on a single computer. They allow processes on the same machine to establish bidirectional connections to exchange either continuous byte streams or datagram messages.

The API is in many places the same as the one used for TCP/IP network sockets. A UNIX domain socket listening for connections may be represented as an inode in the file system, depending on the operating system and the parameters used to bind that socket.

Unix Domain Sockets can only communicate within a Linux OS kernel, they can not communicate externally to a kernel.

Details are provided in the unix(7) man page.
