Chocolatey is trusted by businesses to manage software deployments. Chocolatey integrates w/SCCM, Puppet, Chef, etc. it also works : echo "GET / HTTP/1.0" > http_request.txtĮcho "User-Agent: netcat" > http_request.txt Chocolatey is software management automation for Windows that wraps installers, executables, zips, and scripts into compiled packages. IP2=$(cat http_req2.txt | nc 80 | tail -n 1)Īnd more strange but. Here are the 2 working ways : echo "GET /automation/n09230945.asp HTTP/1.0" > http_req2.txt GREAT and many thanks to both of you guys as I did not feel comfortable with nc at all. Provided my ISP allows outgoing HTTP, is it possible to use netcat in order to get the public IP response from a site like or similar ? w SECS timeout for connects and final net reads Figure 1: Netcat Portscan As seen in Figure 1, the netcat client quickly and quietly scanned 192.168.1.3 on ports 10 through 25, identifying that port 22 is listening using SSH-2.0-OpenSSH 5.3.

It has no "wget" nor "traceroute", and "ping" is just answering "alive" or "not alive". A simple command of ‘nc nv w1 ’ will scan the target IP address for the ports designated.

I'd like to get the public IP of that camera, which is located behind a router. Once you have concluded the test stop netcat by pressing ‘control-c’ on both computers.I have a very basic Linux server running on an IP camera (Busybox). Type some characters and press ‘enter’ and you should see them echo’d on the screen on computer A. This will open a connection to netcat running on computer A. Type the command below and press enter to connect to the VPN server on the IP address and port that you noted in steps 2 & 3 above. On computer B (which is not connected to the VPN)

Type the command below to have netcat listen on the first available port using the example range above (if you are using Windows firewall you may be prompted to allow netcat to communicate with public networks which you must approve for the test to work).

Note the IP address of the VPN server you are connected to using a website such as.

Navigate to the client area and note the port assigned to you e.g.

On Windows you will need to download Netcat for Windows. Netcat should be preinstalled on macOS and is available via most Linux package managers e.g. Computer A and B do not need to be running the same operating system. You will need netcat installed on both computer A and computer B. By doing this you can prove that port forwarding is working correctly. The test will send data from computer B over the Internet to the VPN server and then through the VPN tunnel to computer A. We will call the computer connected to the VPN ‘computer A’ and the one not connected ‘computer B’.

In this guide we’ll show you how to use netcat to send data between two computers where one is connected to the VPN. You will need two computers (or a second virtual machine) in order to run this test and have some basic experience using the command line. It allows you to easily read and write data over a network socket. If you would like to verify that port forwarding is working correctly you can use a tool called netcat which is great for debugging all kinds of network issues.
