What is the difference between SSH client and SSH server?

Question

SSH refers both to the cryptographic network protocol and to the suite of utilities that implement that protocol. SSH uses the client-server model, connecting a Secure Shell client application, which is the end where the session is displayed, with an SSH server, which is the end where the session runs.

What is difference between OpenSSH server and client?

The SSH client always initiates the setup of the secure connection, and the SSH server listens for incoming connection requests (usually on TCP port 22 on the host system) and responds to them. In the connection setup phase, the SSH server authenticates itself to the client by providing its public key.

What is SSH client and server?

Secure Shell (SSH) is a client/server network application. It is used as a communication vehicle between the host system (for example, a laptop computer) and the system command-line interface (CLI).

Why do we need SSH client?

SSH provides password or public-key based authentication and encrypts connections between two network endpoints. It is a secure alternative to legacy login protocols (such as telnet, rlogin) and insecure file transfer methods (such as FTP).

Do you need a server for SSH?

In order to establish an SSH connection, you need two components: a client and the corresponding server-side component. An SSH client is an application you install on the computer which you will use to connect to another computer or a server.
