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. +.P +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 connection is sent to your = standard=20 +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. +.P +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 doesn't really care if it runs in "client" or = "server" +mode -- it still shovels data back and forth until there isn't any = more +left. In either mode, shutdown can be forced after a configurable time = of +inactivity on the network side. +.P +And it can do this via UDP too, so netcat is possibly the "udp = telnet-like" +application you always wanted for testing your UDP-mode servers. UDP, = as +the "U" implies, gives less reliable data transmission than TCP = connections=20 +and some systems may have trouble sending large amounts of data that = way, but +it's still a useful capability to have. +.P +You may be asking "why not just use telnet to connect to arbitrary = ports?" +Valid question, and here are some reasons. Telnet has the "standard = input +EOF" problem, so one must introduce calculated delays in driving = scripts to +allow network output to finish. This is the main reason netcat stays = running +until the *network* side closes. Telnet also will not transfer = arbitrary +binary data, because certain characters are interpreted as telnet = options +and are thus removed from the data stream. Telnet also emits some of = its +diagnostic messages to standard output, where netcat keeps such things +religiously separated from its *output* and will never modify any of = the +real data in transit unless you *really* want it to. And of course = telnet is +incapable of listening for inbound connections, or using UDP instead. = Netcat +doesn't have any of these limitations, is much smaller and faster than = telnet, +and has many other advantages. +.SH OPTIONS +.TP 13 +.I \-g gateway +source-routing hop point[s], up to 8 +.TP 13 +.I \-G num +source-routing pointer: 4, 8, 12, ... +.TP 13 +.I \-h +Display help. +.TP 13 +.I \-i secs +delay interval for lines sent, ports scanned +.TP 13 +.I \-l +listen mode, for inbound connects +.TP 13 +.I \-n +numeric-only IP addresses, no DNS +.TP 13 +.I \-o file +hex dump of traffic +.TP 13 +.I \-p port +local port number +(port numbers can be individual or ranges: lo-hi [inclusive]) +.TP 13 +.I \-q seconds +Quit after EOF is detected on stdin and after a delay.
