SSH is a secure protocol used as the primary means of connecting to Linux servers remotely. It provides a text-based interface by spawning a remote shell. After connecting, all commands you type in your local terminal are sent to the remote server and executed there.
How does SSH work step by step?
The steps involved in creating an SSH session go like this:
- Client contacts server to initiate a connection.
- The server responds by sending the client a public cryptography key.
- The server negotiates parameters and opens a secure channel for the client.
- The user, through their client, logs into the server.
What is SSH and how do you use it?
SSH or Secure Shell is a network communication protocol that enables two computers to communicate (c.f http or hypertext transfer protocol, which is the protocol used to transfer hypertext such as web pages) and share data.
What is SSH and why it is used?
SSH provides password or public-key based authentication and encrypts connections between two network endpoints. … In addition to providing strong encryption, SSH is widely used by network administrators to manage systems and applications remotely, deliver software patches, or execute commands and move files.
How does TCP SSH work?
SSH usually runs over TCP. … Using TCP, SSH is able to accomplish port tunneling and forwarding. These techniques allow data to travel on an unsecured network to a private network by encrypting the data and obscuring the traffic type.
How do I set up SSH?
Set up SSH on macOS/Linux
- Set up your default identity. From the terminal, enter ssh-keygen at the command line. …
- Add the key to the ssh-agent. If you don’t want to type your password each time you use the key, you’ll need to add it to the ssh-agent. …
- Add the public key to your Account settings.
What is the difference between https and SSH?
Any time someone uses a website with a URL that starts with HTTPS, he is on a site with SSL/TLS. SSH is for securely executing commands on a server. SSL is used for securely communicating personal information. SSH uses a username/password authentication system to establish a secure connection.
What is the difference between SSL and SSH?
The first difference between SSL and SSH is their application. SSL is mostly used for establishing a secure connection between website and clients, while SSH is utilized to create secure remote connections on insecure networks. The second difference between SSL and SSH is in the method they both operate.
What is advantage of SSH?
SSH offers encryption for data transfer that restricts hackers and attackers from hacking your server password and user information. Another benefit of using SSH is that it allows you to tunnel other network protocols.

What is SSH used for?
SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding TCP ports and X11 connections; it can transfer files using the associated SSH file transfer (SFTP) or secure copy (SCP) protocols. SSH uses the client–server model.
