Slackware 13.0slackware-13.0

Wed Aug 26 10:00:38 CDT 2009
Slackware 13.0 x86_64 is released as stable!  Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits.  The ISOs are off to the replicator.  This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com.  Please consider
picking up a copy to help support the project.  Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy!  -P.

++.SH NAME
++nc \- TCP/IP swiss army knife
++.SH SYNOPSIS
++.B nc
++.I "[-options] hostname port[s] [ports] ..."
++.br
++.B nc
++.I "-l -p port [-options] [hostname] [port]"
++.SH "DESCRIPTION"
++.B 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.
++.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 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 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 COPYRIGHT
++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.
++.SH BUGS
++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. Continued feedback from the Internet
++community is always welcome!
++.P
++Some port names in /etc/services contain hyphens -- netcat currently
++will not correctly parse those, so specify ranges using numbers if you
++can.

++netcat for Debian
++-----------------
++
++netcat has been compiled with -DGAPING_SECURITY_HOLE turned on. I do
++not believe this is as much of a security hole as the author makes it
++out to be, *if* you know what you're doing (but then, if you didn't,
++you'd still be using telnet ;-)). Since the spawned program will run
++as whatever user started netcat, don't use -e as root. You have been
++warned, so if some cracker breaks into your system due to your own
++stupidity, don't blame me.
++
++A symlink to the netcat binary called 'netcat' has been installed.
++However, the canonical name is still 'nc'. If you use netcat on other
++systems, it will probably only be installed as 'nc', so keep this in
++mind when writing scripts.
