If we receive some data we use the configured text encoding to convert the raw bytes to text and append it to the result. Then, within a loop we read as much data as the buffer will hold, or as much data as there is available to read. Next we create an empty string to hold the ultimate result, and a byte array buffer for reading raw chunks of the response from the stream. First, we configure the Stream with the maximum time to wait for a response. The fifth, and most complicated, section is responsible for receiving the response data from the server, if any. If the user pipes data into my function, the process block will be called once for each item in the pipe.Īt this point, all the user-provided data has been received and then written to the network socket. Depending on how the user calls my function, the process block will be called in two different ways. I need this so I can still read the response from the stream. In the begin block, I create a new TcpClient object, tell it to connect to the specified computer and port, and setup the StreamWriter object to be used for sending the data in the next section. The two remaining optional parameters are the text encoding method and the response timeout which default to ASCII, and infinite respectively. The three mandatory parameters are the name or address of the destination computer, the destination TCP port number, and the data to send. First is the parameter block, defining three mandatory parameters, and two optional. My script consists of essentially six sections. So easy, that I have written such a script, about 70 lines long including formatting in a little over an hour. The tool most similar to Netcat to be included with Windows is the command-line Telnet Client, but it is not easily scriptable and in recent Windows versions it is an optional feature that needs to be intentionally installed.

Netcat is useful for issuing requests to mail servers, web servers, software or hardware control ports, or almost any network-exposed service. I now get to use all the tools Linux has to offer on a daily basis, but I still miss the rich metadata PowerShell passes along the pipe. Another tool is nmap which again, I find easy to use.I have been a long time Windows user and a PowerShell fan since it was introduced. You can setup it easily to listen to a specific port. Even if it seems otherwise, Wireshark is easy to use.

You may also want to download a current version, which is called ncat and can be found in the nmap distribution. A friend recently introduced it to me and it made certain tasks so much easier for me. Sorry if this sounds like an advertisement I don't work for nor am I affiliated with MobaXterm.

For me, there was nothing to install it's just one executable that opens a terminal window in Windows that accepts many Unix commands. The above example will connect you to the hostname on port I discovered that MobaXterm for Windows has the nc netcat command, as well as many other Unix commands, like lspsand kill. While the netcat on this page was removed and quarantined when run, the 'rodneybeede' version linked to near the end of the page tried to connect to the desired port, and wasn't quarantined. I downloaded and extracted these on two systems running 'Symantec Endpoint Protection'. This person ran into the exact same problem read till the end for the version compiled without remote execution. The original nc contained a simple port scanner, but we omitted that from Ncat because we have a preferred tool for that function. Ncat adds many capabilities not found in Hobbit's original nc, including SSL support, proxy connections, IPv6, and connection brokering. Compatibility with the original Netcat and some well known variants is maintained where it doesn't conflict with Ncat's enhancements or cause usability problems. Instead, Ncat makes use of Nmap's well optimized and tested networking libraries. Ncat is our modern reinvention of the venerable Netcat nc tool released by Hobbit in While Ncat is similar to Netcat in spirit, they don't share any source code. It's an implementation of netcat available on the official Nmap site with the port scanning feature removed. I don't need the 'advanced' features which are possibly the reason for the quarantining such as port scanning or remote execution. However these days my anti-virus software Symantec - but I understand others display similar behaviour quarantines netcat. I used to use netcat for Windows to help track down network connectivity issues. Super User is a question and answer site for computer enthusiasts and power users.
