How do UNIX domain sockets work?
Unix sockets are bidirectional. This means that every side can perform both read and write operations. While, FIFOs are unidirectional: it has a writer peer and a reader peer. Unix sockets create less overhead and communication is faster, than by localhost IP sockets.
Why does UNIX require a domain socket?
In the server program, the socket function creates a stream socket in the UNIX domain, and then the bind function assigns a unique name for the socket. The listen function then accepts incoming client connections and creates a connection queue for further incoming requests.
How do I find my hostname and domain name in Linux?
The procedure to find the computer name on Linux:

What is the domain name?
A domain name (often simply called a domain) is an easy-to-remember name that’s associated with a physical IP address on the Internet. It’s the unique name that appears after the @ sign in email addresses, and after www. in web addresses.
How do I use a domain socket?
Here are the steps:
- Call socket() to get a Unix domain socket to communicate through.
- Set up a struct sockaddr_un with the remote address (where the server is listening) and call connect() with that as an argument.
- Assuming no errors, you’re connected to the remote side! Use send() and recv() to your heart’s content!
How do I create a UNIX domain socket in Linux?
To create a UNIX domain socket, use the socket function and specify AF_UNIX as the domain for the socket. The z/TPF system supports a maximum number of 16,383 active UNIX domain sockets at any time. After a UNIX domain socket is created, you must bind the socket to a unique file path by using the bind function.

How do I find my domain name and hostname?
This is also located to the left of the top-level domain, but does not designate a computer or server, just the domain area. The hostname is still far on the left. Example: In the FQDN www.example.ionos.com, “IONOS” denotes a domain name, “example” denotes a subdomain and www is the hostname.

What is a permission flag?
I am not sure that there is a precise definition. Typically permission flags refer to constants defined to represent corresponding permission bits and are used for code portability reasons. Hmm I hope I will also get some more information and answers.
Why isn’t there a standard for Unix commands?
There is no standard or standardization, probably due the different origins of the commands: AT Unix, the BSDs, the GNU project, etc. This lack is inherent in the FS/OSS development process. — IOW, how good are you at herding cats?
