#ÑÑÑman nc
NC(1) NC(1)
NAME
nc - TCP/IP swiss army knife
SYNOPSIS
nc [-options] hostname port[s] [ports] ...
nc -l -p port [-options] [hostname] [port]
DESCRIPTION
netcat is a simple unix utility which reads and writes data across network connections, using TCP or
UDP protocol. It is designed to be a reliable "back-end" tool that can be used directly or easily
driven by other programs and scripts. At the same time, it is a feature-rich network debugging and
exploration tool, since it can create almost any kind of connection you would need and has several
interesting built-in capabilities. Netcat, or "nc" as the actual program is named, should have been
supplied long ago as another one of those cryptic but standard Unix tools.
In the simplest usage, "nc host port" creates a TCP connection to the given port on the given target
host. Your standard input is then sent to the host, and anything that comes back across the connecâ
tion is sent to your standard output. This continues indefinitely, until the network side of the
connection shuts down. Note that this behavior is different from most other applications which shut
everything down and exit after an end-of-file on the standard input.
Netcat can also function as a server, by listening for inbound connections on arbitrary ports and
then doing the same reading and writing. With minor limitations, netcat doesnât really care if it
