Here's netcat 1.11 compiled for both 32 and 64-bit Windows (but note that 64-bit version hasn't been tested much - use at your own risk). I'm providing it here because I never seem to be able to find a working netcat download when I need it. Small update: netcat 1.12 - adds -c command-line option to send CRLF line endings instead of just CR (eg. To talk to Exchange SMTP). One example of this is the telnet command, available from the Command Prompt in Windows. The telnet command uses the Telnet protocol to communicate with a remote device or system. Telnet commands can also be executed on other operating systems such as Linux and macOS, in the same way that telnet commands are executed in Windows. Netcat (or nc in short) is a simple yet powerful networking command-line tool used for performing any operation in Linux related to TCP, UDP, or UNIX-domain sockets. Netcat can be used for port scanning, port redirection, as a port listener (for incoming connections); it can also be used to open remote connections and so many other things. $ nc -w 120 192.168.1.10 8888 Use IPv4 Only with netcat Command. Netcat is a tool that supports both IPv4 and IPv6 and in some cases, we may want to only enable the IPv4 protocol. This is especially useful for listening to a specific port. We will use -4 as an option to enable only IPv4. $ nc -k -4 -l 4444 Use IPv6 Only with netcat Command. Without an option, the Windows version produces a help message: shutdown -s: shutdown-h: Also need -f option to Windows if logged in remotely: sort: sort: start & On Unix, to start a job in the background, use command &. On Windows, the equivalent is start command. See How to run a Windows command as a background job like Unix?
This set of documentation describes the Windows Commands you can use to automate tasks by using scripts or scripting tools.

Command shell overview
The Command shell was the first shell built into Windows to automate routine tasks, like user account management or nightly backups, with batch (.bat) files. With Windows Script Host you could run more sophisticated scripts in the Command shell. For more information, see cscript or wscript. You can perform operations more efficiently by using scripts than you can by using the user interface. Scripts accept all Commands that are available at the command line.
Windows has two command shells: The Command shell and PowerShell. Each shell is a software program that provides direct communication between you and the operating system or application, providing an environment to automate IT operations.
PowerShell was designed to extend the capabilities of the Command shell to run PowerShell commands called cmdlets. Cmdlets are similar to Windows Commands but provide a more extensible scripting language. You can run Windows Commands and PowerShell cmdlets in Powershell, but the Command shell can only run Windows Commands and not PowerShell cmdlets.
For the most robust, up-to-date Windows automation, we recommend using PowerShell instead of Windows Commands or Windows Script Host for Windows automation.
Note
You can also download and install PowerShell Core, the open source version of PowerShell.
Caution
Incorrectly editing the registry may severely damage your system. Before making the following changes to the registry, you should back up any valued data on the computer.
Note
To enable or disable file and directory name completion in the Command shell on a computer or user logon session, run regedit.exe and set the following reg_DWOrd value:
HKEY_LOCAL_MACHINESoftwareMicrosoftCommand ProcessorcompletionCharreg_DWOrd
To set the reg_DWOrd value, use the hexadecimal value of a control character for a particular function (for example, 0 9 is Tab and 0 08 is Backspace). User-specified settings take precedence over computer settings, and command-line options take precedence over registry settings.
Command-line reference A-Z
To find information about a specific command, in the following A-Z menu, click the letter that the command starts with, and then click the command name.

Netcat is a powerful and versatile network tool that is available for Linux, Mac, and Windows machines. It is simple to use and essential learning for everyone interested in network communication.
The core functionality of Netcat is allowing two computers to connect and share resources. The name is a portmanteau of network and concatenate, which is a fancy word for joining things together.
Connections can be made directly between machines via TCP or UDP ports. Once established there are many potential use cases. Communication can work bidirectionally so files or information can move from listener to client or client to listener.
Netcat is known as the IT “Swiss Army Knife” because of its wide range of functionalities. It can be used for simple file sending, chatting, web serving, running code remotely. The list is extensive and varied.
I will highlight some of the more common applications throughout this article.
Notoriously, netcat can be used for creating “back door” access. I will explain how this works, but keep in mind this is no longer part of the nc software due to its potential for malicious use.
Netcat (nc) command examples
Here’s the syntax for the nc command:
The syntax can vary depending on the application, but for most uses, your commands will follow this basic pattern.
Let’s see
1. Create a Connection Using TCP with netcat command
As I mentioned earlier, the core functionality of netcat is joining two machines together. You can set up a connection using TCP to connect two separate machines, you can also emulate that connection using the terminal.
The Listening Machine:
This command opens port 8080 and tells the machine to begin listening on this port.
In order to establish a connection, you will use another terminal and enter the following.
Nc Command On Windows
The Client Machine:
You can also use ‘localhost’ in place of the IP, or use the IP of your second PC here if you are making a remote connection.
That’s it, you have opened a TCP port and established a connection between two systems.
Quick Intro to TCP vs UDP
Why do we use TCP by default? TCP is an older technology than UDP and they operate at different levels of the OSI model. I will give a quick overview of the differences between them and describe some situations where you may choose one over the other.
TCP has strong error-correction capabilities. What does that mean? Basically, this means that while data packets are in transit from system to system, there are continuous tests being performed. These tests make sure that the information from System A is copied accurately to System B. This is a very simplified version of what happens as information travels across networks (the internet).
Windows Equivalent Of Nc
There are many protocols used in internet communication, though, not just TCP. UDP has different rules than TCP. Neither is necessarily “better” but they can each excel at performing different tasks.
Why would we use UDP over TCP or vice versa? It depends on the application. TCP is slower, but more reliable for transferring data accurately.
UDP can be chosen in situations where speed is more important than reliability transmitting information. One example of this is streaming data, like video. Video can be transferred more quickly over UDP, and even if there are errors in the transmission, they are less likely to impact the user experience.
2. Create a connection using UDP with nc command
The steps for making a UDP connection are virtually identical to the ones we’ve already followed. You will add an option flag to specify that the type of port you want to open is UDP, not the default TCP.
It’s that simple. That’s all you need to do to open UDP port ‘999’.
You might wonder if you can use TCP and UDP with the same port number. You can, because they are separate protocols.
3. Use nc command to transfer files between remote systems
There are other methods for transferring files from one system to another. Ca driver license restriction code 08. You can also use the netcat command for this purpose.
For this example, I created a demo that illustrates a remote file transfer from my Linux machine to my MacBook Pro.
Set up the Linux PC to Receive
You begin listening on the receiving machine on TCP port 9999. The ‘
>
‘ tells the machine you are expecting a file to be transferred. The name that follows is the local name for the file.Set up the Mac PC to Send
The IP address here belongs to the Linux machine. You flip the symbol to ‘
<
‘ and the file ‘toLinux.file’ will be copied onto the remote machine as ‘fromMac.file’.Here’s an example using two different machines to send a file.
4. Use nc command for port scanning
There might be more efficient options for port scanning, but it can be done with netcat. Since netcat comes installed by default on most operating systems, it’s nice to know how to do this if you need to do some quick troubleshooting. You’ll use the ‘-n’ and display verbose output.
This attempts to make a connection to ports between 1-100. Port 80 is HTTP, as I’m sure many of you know. This port is normally open on machines because it is used for connecting to the internet.
When I use this command, I’m actually attempting to connect to all of the ports between 1-100. It successfully connects to port 80, but generates an error message from Apache. I end up with some HTML output on the terminal because my computer sees it as a bad page request.
Zero I/O Mode
Skyrim ps4 magic mods. To avoid this, you can use the
-z
flag, which stands for zero input/output. This is the built-in port-scanning mode for netcat. I still get the same language, but it does not actually make the connection to port 80 generating the bad request error. Instead it continues through all scanned ports.5. Chat with Netcat
This is a more fun way to use netcat. When you establish a TCP connection like above, you can actually “chat” from machine to machine. It’s less novel in an era where texting and chat applications are ubiquitous but this would have totally blown someone’s mind back in 1996.
Here’s an animation that shows me talking from one terminal to another.
Turtle art for mac. Pretty cool, right?
Bonus Tip: Create a backdoor with nc command
Dell intel management engine 9.5. I will show this for demonstration purposes only. Please be aware that unauthorized use of this command could be considered criminal activity in your locale.
In fact, this command no longer does anything with ‘nc’. There are ways to do it, but you will have to find them somewhere else. Once again, this is intended only to show the capability.
The -e flag makes something executable. A common way for malicious actors to gain access is to create such a backdoor on an open port and use that to execute scripts or otherwise manipulate the file system.
So if the attacker somehow gained the access to the “victim” machine, he/she can create a backdoor like this:
Now the attackers can use this backdoor to access into the system remotely and execute commands. So, from attacker’s system:
This enables the attacker to access your computer remotely from the command line. Once connected, I can run bash commands similarly to how I could if I was using the computer directly.
I’m sure you can imagine how someone without the best of intentions could abuse this power. This makes it very important to monitor port activity on any network.
I hope you enjoyed this brief introduction to the netcat command. As always, let us know what you think in the comment section.
