PuTTY, a lightweight SSH client developed for Windows systems is also available to use on Linux machines, including Ubuntu. Developed by Simon Tatham, it has become probably the most popular SSH client in use today, although may not be as popular as it once was. The things most people like about PuTTY are, it’s lightweight, readily available to download, efficient, compatible with most operating systems, and gets the jobs done. In fact, on Windows systems, no need to install it. Download the PuTTY executable and run it. It’s that simple! I’m not saying PuTTY is the best SSH client out there. Nope. PuTTY can’t compete with many of the well-maintained SSH clients. But PuTTY has many advantages that the others done have and that’s why people still go to PuTTY when they need to quickly connect to a system via SSH. To install PuTTY, log on to Ubuntu Linux and open the command line terminal by pressing Ctrl — Alt — T keys on your keyboard. When the terminal opens, run the commands below to install PuTTY. After installing, go to the Activity overview and search for PuTTY SSH Client, then select launch. When you open it, you’ll get the same interface you’ll have on Windows systems. Just like how you’d use it on Windows systems, this app functions the same way on Linux operating systems. The layout looks the same, but with Ubuntu color and themes. To connect to an SSH server, type the IP address of the server and port number, then click Open. Not just SSH, PuTTY can be used to establish Telnet, Serial, and Rlogin connections. SSH is mostly used because of its security and how it handles data being transferred between two network systems. That should do it!
