UNIX domain sockets enable efficient communication between processes that are running on the same z/TPF processor. UNIX domain sockets support both stream-oriented, TCP, and datagram-oriented, UDP, protocols. You cannot start a UNIX domain socket for raw socket protocols.

Creation of a new socket will fail if the process does not have write and search (execute) permission on the directory the socket is created in. Connecting to the socket object requires read/write permission. This behavior differs from many BSD- derived systems which ignore permissions for UNIX …

At that point, you're talking directly to your network interface's driver. For more information see socket(2), ip(7), packet(7), raw(7), socket(7) and unix(7). Unix sockets usually are assigned numbers in pairs, and are usually consecutive. So the pair for you would likely be 1013410+/-1.

The child does the opposite, close(fds[0 2018-02-07 Unix socket In a TCP/IP network, the method of directing data to the appropriate application in a computer. Also called a "network socket" or "TCP/IP socket," the combination of the IP address of the station and a port number make up a socket.

The downside of that being that only local connections are UNIX domain sockets are a method by which processes on the same host can communicate. Communication is bidirectional with stream sockets and unidirectional with datagram sockets. UNIX domain sockets use the file system as the address name space i.e, instead of identifying a server by an IP address and port, a UNIX domain socket is known by a pathname.

Unix sockets usually are assigned numbers in pairs, and are usually consecutive.

The default location for the Unix socket file that the server uses for communication with local clients is /tmp/mysql.sock. (For some distribution formats, the directory might be different, such as /var/lib/mysql for RPMs.) On some versions of Unix, anyone can delete files in the /tmp directory or other similar directories used for temporary files.

The first, unix_server_socket.c, creates a passive socket and accepts connections. For each connection, it will read from the socket and echo the results into STDOUT. The second, A connection that is created with a Unix socket file is faster than TCP/IP but can only be used when connecting to a server on the same computer. When you use a Unix socket file, you can skip a hostname and port in the connection string.

On the server host in the command line, run the following command: … A UNIX socket, AKA Unix Domain Socket, is an inter-process communication mechanism that allows bidirectional data exchange between processes running on the same machine. IP sockets (especially TCP/IP sockets) are a mechanism allowing communication between processes over the network. The first parameter to the socket system call is the domain. The domain is actually the communication domain and it selects the protocol family to be used for communication.

This means, that socket system calls are used for them. The difference between FIFOs and Unix sockets, is that The unix_socket authentication plugin allows the user to use operating system credentials when connecting to MariaDB via the local Unix socket file.
