![]() SOCAT (SOcket CAT) is a command-line utility that establishes two bidirectional byte streams and data transfer between them. Netcat often also offers non-TCP transports (UDP, sometimes SCTP, local Unix sockets) whereas Telnet clients are TCP-only. It can be used with ASCII protocols just like telnet, but also can and often is used as a “pipe” into TCP for batch data transfer, because it will not alter any byte sent through it. What is the difference between telnet and Netcat? Most common use for Netcat when it comes to hacking is setting up reverse and bind shells, piping and redirecting network traffic, port listening, debugging programs and scripts and banner grabbing. Netcat is a great network utility for reading and writing to network connections using the TCP and UPD protocol. Netcat (often abbreviated to nc) is a computer networking utility for reading from and writing to network connections using TCP or UDP. ![]() It is one of the most powerful tools in the network and system administrators arsenal, and it as considered as a Swiss army knife of networking tools. Netcat (or nc ) is a command-line utility that reads and writes data across network connections, using the TCP or UDP protocols. To determine the version of Netcat, simply type nc –h or netcat –h. Others have at least one or more versions of Netcat available as a pre-compiled package. ![]() Many mainstream Linux distributions come with Netcat already compiled and installed. For example, while the traditional Netcat has a simple port scanning feature, Ncat lacks that feature because Nmap can be used more effectively for that purpose. Ncat was developed for the Nmap Project it combines the best capabilities of the various Netcat variants into a single sophisticated tool. What is the difference between netcat and NCAT? After the installation is done type ‘nc -h’ like shown in Figure3. Open a new terminal window and type ‘sudo apt-get install netcat’ like shown in Figure 1. The first method is very easy to use and friendly for beginners.
