объединение и перенаправление сокетов (Concatenate and redirect sockets)
MISC OPTIONS
-C, --crlf (Use CRLF as EOL)
This option tells Ncat to convert LF line endings to CRLF
when taking input from standard input. This is useful for
talking to some stringent servers directly from a terminal in
one of the many common plain-text protocols that use CRLF for
end-of-line.
-h, --help (Help screen)
Displays a short help screen with common options and
parameters, and then exits.
--recv-only (Only receive data)
If this option is passed, Ncat will only receive data and
will not try to send anything.
--send-only (Only send data)
If this option is passed, then Ncat will only send data and
will ignore anything received. This option also causes Ncat
to close the network connection and terminate after EOF is
received on standard input.
--no-shutdown (Do not shutdown into half-duplex mode)
If this option is passed, Ncat will not invoke shutdown on a
socket after seeing EOF on stdin. This is provided for
backward-compatibility with OpenBSD netcat, which exhibits
this behavior when executed with its '-d' option.
-n, --nodns (Do not resolve hostnames)
Completely disable hostname resolution across all Ncat
options, such as the destination, source address, source
routing hops, and the proxy. All addresses must be specified
numerically. (Note that resolution of proxy destinations is
controlled separately via option --proxy-dns.)
-t, --telnet (Answer Telnet negotiations)
Handle DO/DONT WILL/WONT Telnet negotiations. This makes it
possible to script Telnet sessions with Ncat.
--version (Display version)
Displays the Ncat version number and exits.
