$ sudo apt-get install openssh-server This is the portable version of OpenSSH, a free implementation of the Secure Shell protocol as specified by the IETF secsh working group. This same method should work on Debian and other debian based distros as well. On ubuntu install the package openssh-server. In this post we are going to see how to setup the ssh server and client on ubuntu and do some secure communication. And the other part is an ssh client that can speak the ssh protocol and communicate with the ssh server. First is the secure shell server that runs on the machine that is to be controlled remotely. It can be used to provide applications with a secure communication channel.įor secure shell, we need 2 components. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. It provides secure encrypted communications between two untrusted hosts over an insecure network. Ssh (Secure Shell) is a program for logging into a remote machine and for executing commands on a remote machine. The communication is wrapped with ssl encryption and called secure shell. If you have worked on linux servers online from command line, you probably have used it. A shell access on any system enables a user to run commands and control the system. It is technically a secure version of telnet.
