Secure Shell Diagram. Nfs client nfs server mount ssh sshd nfs. Secure shell or ssh is used to create a secure channel between a local and remote computer.
It allows you to connect to a server or multiple servers without having you to remember or enter your password for each system that is to login remotely from one system into another. The service was created as a secure replacement for the unencrypted telnet and uses cryptographic techniques to ensure that all communication to and from the remote server happens in an encrypted manner. Ssh or secure shell is a secure protocol and the most common way of safely administering remote servers.
Strong authentication with ssh keys there are several options that can be used for user authentication.
Apart from the use of secure shell ssh for secure remote access we can use it for tunnelling between an nfs client and server so that nfs traffic will be encrypted. It establishes a secure connection and then provides a higher level of protection for data while transferring it. Ssh file transfer protocol sftp is designed as an extension of the ssh2 protocol.
