Install netcat in Linux: sudo apt-get install netcat Compile Netcat From Source: 1. Download Netcat from an official source 2. To decompress it run the following command, gunzip netcat-0.7.1.tar.gz Here, "netcat-0.7.1.tar.gz" is the name of the file. 3. untar the file. tar -xf netcat-0.7.1.tar 4.

Step 2: Open a terminal in Linux and install Netcat on both devices. Step 3: type $ifconfig in d1 and note down your localhost IP address, ifconfig is used to get our device's IP address. Step 4: Now in d1 run command $nc -nvlp 1234 where "1234" is port number, d1 will now act as a listener. Where: -n: nodns, Do not resolve hostname vis DNS-v: verbose, set verbosity level-l: listener, binds and listen for incoming connection-p: source-port port, Specify source port to use Step 5: in d2 type $nc <localhost IP> 1234 and hit enter. Step 6: Simple chat is now created.
