HOW TO INSTALL SSH SERVICE ON REDHAT ?

Secure shell (SSH) can be used to provide similar functionality as telnet, but it is much more secure. Telnet is consider insecure mainly because it sendsusername and password information in clear text. Therefore, telnet should be replaced with SSH.

SSH employs encryption through certificates and authenticates the server to client.

SSH operates on TCP port 22.
