Install OpenSSH in Linux What is OpenSSH?OpenSSH is a free open source set of computer tools used to provide secure and encrypted communication over a computer network by using the ssh protocol. Many people, new to computers and protocols, create a misconception about OpenSSH, they think it is a protocol, but it is not, it is a set of computer programs that use the ssh protocol.OpenSSH is developed by the Open BSD group and it is released under Simplified BSD License. A main factor which has made possible for OpenSSH to be used so much among system administrators is its multi-platform capability and very useful nice features it has. The latest version is OpenSSH 6.4 which has been released on November 8, 2013.This version of OpenSSH comes with many new features and patches, so if you already use OpenSSH for administering your machines, I suggest you to do an upgrade. Why Use OpenSSH And Over Telnet Or Ftp?The most important reason why should use OpenSSH tools over ftp and telnet is that all communications and user credentials using OpenSSH are encrypted, they are also protected from man in the middle attacks. If a third party tries to intercept your connection, OpenSSH detects it and informs you about that.
