Netcat, also known as the Swiss Army Knife, is a common network tool for hackers and system administrators, originally developed for file transfer and later developed many powerful features, such as the ability to perform bulk host service scans.Previously, another more common scanning tool for bulk host services was introduced: Nmap.The installation of the Netcat is also very simple, with the direct Yum installation:Yum Install NCIn general, it is not recommended to install NC in production env
