In this article, i will take you through the steps to install netcat command in Linux. nc command in Linux can be used for variety of purposes like checking the status of remote ports, initiating chat services between server and client, start listening on some ports for incoming connections etc. Now a days there are lot of open source networking tools available in Linux Based Systems to perform network troubleshooting activity. netcat is one such tool.

Netcat is a relatively easy program to obtain, configure, and install. In fact, most distributions of Unix and Linux have a precompiled version of Netcat already installed and configured. Netcat 1.11 for Win32/Win64. Here's netcat 1.11 compiled for both 32 and 64-bit Windows (but note that 64-bit version hasn't been tested much - use at your own risk). I'm providing it here because I never seem to be able to find a working netcat download when I need it. Small update: netcat 1.12 - adds -c command-line option to send CRLF line. Download link: nc1: Windows: nc -nvlp 22222: Kali: nc -nv Target IP 2222#netcat#chat windows netcat.

In this session we will only look into the steps to install netcat on RedHat Based Systems. I will cover other networking tools in future articles. Since netcat package does not comes by default in RedHat Based systems, so we need to install it manually using below steps.

Introduction

Ncat is a feature-packed networking utility which reads andwrites data across networks from the command line. Ncat was writtenfor the Nmap Project as a much-improved reimplementation of thevenerable Netcat. It usesboth TCP and UDP for communication and is designed to be a reliableback-end tool to instantly provide network connectivity to otherapplications and users. Ncat will not only work with IPv4 and IPv6 butprovides the user with a virtually limitless number of potential uses.

Among Ncat’s vast number of features there is the ability to chainNcats together, redirect both TCP and UDP ports to other sites, SSLsupport, and proxy connections via SOCKS4 or HTTP (CONNECT method)proxies (with optional proxy authentication as well). Some generalprinciples apply to most applications and thus give you the capabilityof instantly adding networking support to software that would normallynever support it.

Ncat is integrated with Nmap and is available in the standard Nmapdownload packages (including source code and Linux, Windows, and Macbinaries) available fromthe Nmap download page.You can also find it inour SVNsource code repository.

Many users have asked for a statically compiled version of ncat.exe that they can just drop on a Windows system and use without having to run any installer or copy over extra library files. We have built a statically compiled Windows binary version of Ncat 5.59BETA1. You can download it inside a zip file here. To ensure the file hasn't been tampered with, you can check the cryptographic signatures. If you need a portable version of a newer Ncat release, see the Ncat portable compilation instructions.
