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 \__.=|___E 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 connection 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 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. 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 and some systems may have trouble sending large amounts of data that way, but it's still a useful capability to have. 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. Some of netcat's major features are: Outbound or inbound connections, TCP or UDP, to or from any ports Full DNS forward/reverse checking, with appropriate warnings Ability to use any local source port Ability to use any locally-configured network source address Built-in port-scanning capabilities, with randomizer Built-in loose source-routing capability Can read command line arguments from standard input Slow-send mode, one line every N seconds Hex dump of transmitted and received data Optional ability to let another program service established connections Optional telnet-options responder Efforts have been made to have netcat "do the right thing" in all its various modes. If you believe that it is doing the wrong thing under whatever circumstances, please notify me and tell me how you think it should behave. If netcat is not able to do some task you think up, minor tweaks to the code will probably fix that. It provides a basic and easily-modified template for writing other network applications, and I certainly encourage people to make custom mods and send in any improvements they make to it. This is the second release; the overall differences from 1.00 are relatively minor and have mostly to do with portability and bugfixes. Many people provided greatly appreciated fixes and comments on the 1.00 release. Continued feedback from the Internet community is always welcome! Netcat is entirely my own creation, although plenty of other code was used as examples. It is freely given away to the Internet community in the hope that it will be useful, with no restrictions except giving credit where it is due. No GPLs, Berkeley copyrights or any of that nonsense. The author assumes NO responsibility for how anyone uses it. If netcat makes you rich somehow and you're feeling generous, mail me a check. If you are affiliated in any way with Microsoft Network, get a life. Always ski in control. Comments, questions, and patches to hobbit@avian.org. Building ======== Compiling is fairly straightforward. Examine the Makefile for a SYSTYPE that matches yours, and do "make ". The executable "nc" should appear. If there is no relevant SYSTYPE section, try "generic". If you create new sections for generic.h and Makefile to support another platform, please follow the given format and mail back the diffs. There are a couple of other settable #defines in netcat.c, which you can include as DFLAGS="-DTHIS -DTHAT" to your "make" invocation without having to edit the Makefile. See the following discussions for what they are and do. If you want to link against the resolver library on SunOS [recommended] and you have BIND 4.9.x, you may need to change XLIBS=-lresolv in the Makefile to XLIBS="-lresolv -l44bsd". Linux sys/time.h does not really support presetting of FD_SETSIZE; a harmless warning is issued. Some systems may warn about pointer types for signal(). No problem, though. Exploration of features ======================= Where to begin? Netcat is at the same time so simple and versatile, it's like trying to describe everything you can do with your Swiss Army knife. This will go over the basics; you should also read the usage examples and notes later on which may give you even more ideas about what this sort of tool is good for. If no command arguments are given at all, netcat asks for them, reads a line from standard input, and breaks it up into arguments internally. This can be useful when driving netcat from certain types of scripts, with the side effect of hiding your command line arguments from "ps" displays. The host argument can be a name or IP address. If -n is specified, netcat will only accept numeric IP addresses and do no DNS lookups for anything. If -n is not given and -v is turned on, netcat will do a full forward and reverse name and address lookup for the host, and warn you about the all-too-common problem of mismatched names in the DNS. This often takes a little longer for connection setup, but is useful to know about. There are circumstances under which this can *save* time, such as when you want to know the name for some IP address and also connect there. Netcat will just tell you all about it, saving the manual steps of looking up the hostname yourself. Normally mismatch- checking is case-insensitive per the DNS spec, but you can define ANAL at compile time to make it case-sensitive -- sometimes useful for uncovering minor errors in your own DNS files while poking around your networks. A port argument is required for outbound connections, and can be numeric or a name as listed in /etc/services. If -n is specified, only numeric arguments are valid. Special syntax and/or more than one port argument cause different behavior -- see details below about port-scanning. The -v switch controls the verbosity level of messages sent to standard error. You will probably want to run netcat most of the time with -v turned on, so you can see info about the connections it is trying to make. You will probably also want to give a smallish -w argument, which limits the time spent trying to make a connection. I usually alias "nc" to "nc -v -w 3", which makes it function just about the same for things I would otherwise use telnet to do. The timeout is easily changed by a subsequent -w argument which overrides the earlier one. Specifying -v more than once makes diagnostic output MORE verbose. If -v is not specified at all, netcat silently does its work unless some error happens, whereupon it describes the error and exits with a nonzero status. Refused network connections are generally NOT considered to be errors, unless you only asked for a single TCP port and it was refused. Note that -w also sets the network inactivity timeout. This does not have any effect until standard input closes, but then if nothing further arrives from the network in the next seconds, netcat tries to read the net once more for good measure, and then closes and exits. There are a lot of network services now that accept a small amount of input and return a large amount of output, such as Gopher and Web servers, which is the main reason netcat was written to "block" on the network staying open rather than standard input. Handling the timeout this way gives uniform behavior with network servers that *don't* close by themselves until told to. UDP connections are opened instead of TCP when -u is specified. These aren't really "connections" per se since UDP is a connectionless protocol, although netcat does internally use the "connected UDP socket" mechanism that most kernels support. Although netcat claims that an outgoing UDP connection is "open" immediately, no data is sent until something is read from standard input. Only thereafter is it possible to determine whether there really is a UDP server on the other end, and often you just can't tell. Most UDP protocols use timeouts and retries to do their thing and in many cases won't bother answering at all, so you should specify a timeout and hope for the best. You will get more out of UDP connections if standard input is fed from a source of data that looks like various kinds of server requests. To obtain a hex dump file of the data sent either way, use "-o logfile". The dump lines begin with "<" or ">" to respectively indicate "from the net" or "to the net", and contain the total count per direction, and hex and ascii representations of the traffic. Capturing a hex dump naturally slows netcat down a bit, so don't use it where speed is critical. Netcat can bind to any local port, subject to privilege restrictions and ports that are already in use. It is also possible to use a specific local network source address if it is that of a network interface on your machine. [Note: this does not work correctly on all platforms.] Use "-p portarg" to grab a specific local port, and "-s ip-addr" or "-s name" to have that be your source IP address. This is often referred to as "anchoring the socket". Root users can grab any unused source port including the "reserved" ones less than 1024. Absence of -p will bind to whatever unused port the system gives you, just like any other normal client connection, unless you use -r [see below]. Listen mode will cause netcat to wait for an inbound connection, and then the same data transfer happens. Thus, you can do "nc -l -p 1234 < filename" and when someone else connects to your port 1234, the file is sent to them whether they wanted it or not. Listen mode is generally used along with a local port argument -- this is required for UDP mode, while TCP mode can have the system assign one and tell you what it is if -v is turned on. If you specify a target host and optional port in listen mode, netcat will accept an inbound connection only from that host and if you specify one, only from that foreign source port. In verbose mode you'll be informed about the inbound connection, including what address and port it came from, and since listening on "any" applies to several possibilities, which address it came *to* on your end. If the system supports IP socket options, netcat will attempt to retrieve any such options from an inbound connection and print them out in hex. If netcat is compiled with -DGAPING_SECURITY_HOLE, the -e argument specifies a program to exec after making or receiving a successful connection. In the listening mode, this works similarly to "inetd" but only for a single instance. Use with GREAT CARE. This piece of the code is normally not enabled; if you know what you're doing, have fun. This hack also works in UDP mode. Note that you can only supply -e with the name of the program, but no arguments. If you want to launch something with an argument list, write a two-line wrapper script or just use inetd like always. If netcat is compiled with -DTELNET, the -t argument enables it to respond to telnet option negotiation [always in the negative, i.e. DONT or WONT]. This allows it to connect to a telnetd and get past the initial negotiation far enough to get a login prompt from the server. Since this feature has the potential to modify the data stream, it is not enabled by default. You have to understand why you might need this and turn on the #define yourself. Data from the network connection is always delivered to standard output as efficiently as possible, using large 8K reads and writes. Standard input is normally sent to the net the same way, but the -i switch specifies an "interval time" which slows this down considerably. Standard input is still read in large batches, but netcat then tries to find where line breaks exist and sends one line every interval time. Note that if standard input is a terminal, data is already read line by line, so unless you make the -i interval rather long, what you type will go out at a fairly normal rate. -i is really designed for use when you want to "measure out" what is read from files or pipes. Port-scanning is a popular method for exploring what's out there. Netcat accepts its commands with options first, then the target host, and everything thereafter is interpreted as port names or numbers, or ranges of ports in M-N syntax. CAVEAT: some port names in /etc/services contain hyphens -- netcat currently will not correctly parse those, so specify ranges using numbers if you can. If more than one port is thus specified, netcat connects to *all* of them, sending the same batch of data from standard input [up to 8K worth] to each one that is successfully connected to. Specifying multiple ports also suppresses diagnostic messages about refused connections, unless -v is specified twice for "more verbosity". This way you normally get notified only about genuinely open connectionswill nes and tu2 -zthe targ20-30"his win, ten connerying ne evene pobe ne be20st, a30 [n, insdel] is at the tar,me" any witd livelyuniforn you abo thFTPs a serveto teln a serveat and mophel wrongeyouye>".
