Netcat can be used as a server. If you run it as shown below, it will listen on port 12345 (on all interfaces): $ nc -l -p 12345 You can add the “-v” parameter to display the action results in more detail, and the (-vv) parameter to get statistics on how many bytes were transferred during the current connection session. In fact, it is more convenient than regular telnet, because you can terminate the connection at any time by pressing Ctrl + C and it processes binary data as normal (no escape sequences, nothing).
If you remember, I said that netcat is a Swiss army knife. What would this knife be if it could not be used as an ordinary knife? This is why netcat can be used instead of the usual telnet: $ nc 80 Let’s start with a few simple examples and then we will use them as basic ones. On Slackware, you can install it as a package from the package directory: $ sudo installpkg If you have Slackware, FreeBSD, NetBSD, Solaris, or Mac, download the nc sources and do: $ tar -zxf Īnother way to do this on a Mac is if you have MacPorts: $ sudo port install netcat If you have Fedora or a Fedora based system such as CentOS, do: $ sudo yum install netcat If you have Debian or a system based on Debian, such as Ubuntu, do the following: $ sudo aptitude install netcat In 2006, netcat got the 4th place in the survey “100 Network Security Utilities”, so it is definitely the tool you need to know. Some of its features include port scanning, file transfer, port listening, and it can be used as a backdoor. The netcat functionality is useful to the same extent that the versatility and handiness of the reputable pocket Swiss Army Knife is useful. Netcat utility is often called “Swiss Army Knife”, in the good sense of the word. What is Netcat?
