What is telnet?
Telnet is a protocol that provides a command line interface for communication with a remote device or server. Sometimes it is employed for remote management but also for initial device setup like network hardware. It stands for Teletype Network, but it can also be used as a verb; 'to telnet' is to establish a connection using the Telnet protocol. An alternative to telnet on MAC is "netcat". Here is a post on "how to install netcat on MAC OSX".
How does 'telnet' work?
Telnet provides users with a bidirectional interactive text-oriented communication system utilizing a virtual terminal connection over 8 byte. User data is interspersed in-band with telnet control information over the transmission control protocol (TCP). Often, Telnet was used on a terminal to execute functions remotely.
The user connects to the server by using the Telnet protocol, which means entering Telnet into a command prompt by following this syntax: telnet hostname port. The user then executes commands on the server by using specific Telnet commands into the Telnet prompt. To end a session and log off, the user ends a Telnet command with Telnet.
Is brew/Homebrew safe?
Brew is a open source package manager (that runs as a command from Terminal.app and uses your Mac’s wifi / internet to download and install supported programs). Using Homebrew, anyone can install thousands of softwares and apps on Macbook Pro, Macbook Air, Mac Mini, iMac, Mac Pro or any PC running MacOS etc. Key alternatives to application installers on Mac OS X include AppStore, Macports, PKG file or DMG files, Nix, Mac Ports to name a few.
Supported versions:
These installation instructions will work on all latest / core versions of MacOS (including Snow Leopard, Mountain Lion, Mavericks, Yosemite, El Capitan, Sierra, High Sierra, Mojave, Catalina, Big Sur, plus MacOS Server)
