Play with Netcat in Ubuntu
Now that you know what netcat is , it is time for some basic operations and real life tasks with the TCP/IP swiss army knife.Linux distributions come with netcat already compiled and installed but I will cover how
to install and use netcat in ubuntu. You can choose to install netcat with the ‘apt-get install’ command or compile and install it from source. The second method is not as easy as the first one and requires some basic knowledge about linux command line , commands such as tar, make and install. The first method is very easy to use and friendly for beginners. Open a new terminal window and type ‘sudo apt-get install netcat’ like shown in Figure 1.
