Systems that operate on the same server may talk to one another working with Unix Area Sockets (UDS). Unix Domain Sockets could be stream-based mostly, or datagram-based mostly. When utilizing domain sockets, data is exchanged between programs directly during the operating method’s kernel via data files within the host filesystem.
This tutorial employs IPv4 sockets, but When your network supports it, attempt tests and working with IPv6 if possible. One method to aid this conveniently is by using the perform socket.getaddrinfo(). It interprets the host and port arguments into a sequence of 5-tuples that contains all of the mandatory arguments for making a socket connected to that company.
