Monitor a local unix domain socket use socat. install it if not exists. $ sudo apt install -y socat and launch server program then input following commands.
UNIX domain sockets (with address family AF_UNIX or AF_LOCAL ) are restricted to the local host and offer a special authentication mechanism: credentials
In a sense, sockets are a network that is entirely contained within the kernel; rather than using network interfaces to send data, that same data can be sent directly between programs. I'm using lua-socket 3.0rc1.3 (that comes with Ubuntu Trusty) and lua 5.1. I'm trying to listen on a unix domain socket, and the only example code I can find is this -- send stdin through unix soc IO::Socket::UNIX provides an object interface to creating and using sockets in the AF_UNIX domain. It is built upon the IO::Socket interface and inherits all the methods defined by IO::Socket. #CONSTRUCTOR # new ( [ARGS] ) Creates an IO::Socket::UNIX object, which is a reference to a newly created symbol (see the Symbol package). There's a trick to using Unix Domain Socket with datagram configuration.
When one establishes a connection in stream sockets, an endpoint for the client is implicitly created by the operating system. netcat-openbsd supports connecting to UNIX-domain sockets. Using this you can connect to either a UNIX-domain stream socket or a UNIX-domain datagram socket, and therefore you have to tell the socket's type to netcat. for example, /dev/log file in Linux is a UNIX-domain datagram socket socket, thus nc -U /dev/log won't work. Instead use nc -uU It can display stats for PACKET sockets, TCP sockets, UDP sockets, DCCP sockets, RAW sockets, Unix domain sockets, and more. It allows showing information similar to netstat command.

for example, /dev/log file in Linux is a UNIX-domain datagram socket socket, thus nc -U /dev/log won't work. Instead use nc -uU 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.
Unix domain sockets are an inter-process communication (IPC) feature that use the file-system as an address space, and file-system permissions for security. Other than that, they generally work like regular network sockets. Lots of Linux software uses domain sockets for local connections; for example, Docker creates a /var/run/docker.sock
net) via det här Unix- domänuttaget.
The argument for using Unix domain sockets is that they are fast and easy to use. In fact, they are being use abundantly in your Linux system. You can check out the Unix domain sockets on your system by giving the command, " ss -f unix ". 2020-08-27
Unix sockets are addressed as files.

Communication is bidirectional with stream sockets and unidirectional with datagram sockets. fd = socket(AF_UNIX, SOCK_STREAM, 0);

Unix domain socket 又叫 IPC(inter-process communication 进程间通信) socket，用于实现同一主机上的进程间通信。 socket 原本是为网络通讯设计的，但后来在 socket 的框架上发展出一种 IPC 机制，就是 UNIX domain socket。

Valid socket types in the UNIX domain are: SOCK_STREAM (compare to TCP) – for a stream-oriented socket For UNIX domain sockets, file and directory permissions restrict which processes on the host can open the file, and thus communicate with the server. Therefore, UNIX domain sockets provide an advantage over Internet sockets (to which anyone can connect, unless extra authentication logic is implemented).
The proper name for unix sockets is Unix Domain Sockets, because they all reside within one computer. In a sense, sockets are a network that is entirely contained within the kernel; rather than using network interfaces to send data, that same data can be sent directly between programs.

UNIX domain sockets are only available at compile time if supported by the target operating system. A program may test for the macro BOOST_ASIO_HAS_LOCAL_SOCKETS to determine whether they are supported. Accessing a Unix Domain Socket. As mentioned, Unix domain sockets are based on path names, so the first thing we need is a path that we can then turn into a socket address. This can be any path, but to make sure we have the required permission, I'll use a file in the home directory. 2016-12-18 · Unix Domain Sockets¶ From the programmer’s perspective there are two essential differences between using a Unix domain socket and an TCP/IP socket.
