UNIX DOMAIN SOCKETS
The -U option (same as --unixsock) causes Ncat to use Unix domain
sockets rather than network sockets. Unix domain sockets exist as
an entry in the filesystem. You must give the name of a socket to
connect to or to listen on. For example, to make a connection,
ncat -U ~/unixsock
To listen on a socket:
ncat -l -U ~/unixsock
Listen mode will create the socket if it doesn't exist. The
socket will continue to exist after the program ends.
Both stream and datagram domain sockets are supported. Use -U on
its own for stream sockets, or combine it with --udp for datagram
sockets. Datagram sockets require a source socket to connect
from. By default, a source socket with a random filename will be
created as needed, and deleted when the program ends. Use the
--source with a path to use a source socket with a specific name.
