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.
