How to make the most of OpenSSH

OpenSSH is a network connectivity and remote login tool that securely encrypts all traffic, originally developed by OpenBSD developers for use in their operating system. Considering the OpenBSD developers’ primary focus on security, it is no surprise that OpenSSH quickly became the standard remote login implementation for all Linux and Unix operating systems. OpenSSH uses a client server model with the ssh command providing client functionality and sshd providing server functionality.
