SSH#

Secure Shell (SSH) refers to a protocol that allows clients to access and execute commands or actions on remote computers. On Linux-based hosts and servers, as well as other Unix-like operating systems, SSH is one of the permanently installed standard tools and is the preferred choice for many administrators to configure and maintain a computer through remote access. It is an older and very proven protocol that does not require or offer a graphical user interface (GUI). For this reason, it works very efficiently and occupies very few resources.
