$ exit How Does SSH Work To Protect Data Between Devices? To disconnect from the remote server, you can issue the following command in the Terminal: Later in the article I’ll discuss how we can eliminate the need for passwords altogether by generating private/public key pairs instead, where the user shares the public key on the remote server while retaining the private key on the workstation, thus allowing the user to SSH into the remote server using a key handshake without the need for the use of passwords. $ SSH it is assumed that remote_host is the IP address of the server the user is remote administering doesn’t have to be as it could be the FQDN of the remote server, but typically it is the IP address of that remote server.

To log in when the username & password on the remote server is different, you have to issue the command as follows: This is why a lot of Sysadmins choose the same username as that which they use on their workstations. If the username on the remote server is different, then SSH needs to know what that username is because it uses the password associated with that user’s username when making the connection. However, the command above makes the assumption that the username on the remote system is the same as the username of the person who is attempting to remote into it using SSH. The most basic command to logon to a remote server from a user’s workstation (server or client) is: This is where SSH and the protocol that supports it comes in. So, it is imperative that if someone like this needs to logon to a remote server, then it should be done securely. It may even be that it’s impossible for a Sysadmin to sit in front of a Linux server to log in to address & fix issues on a network or on the server because they are geographically separated from the server. There are many times when system admins can’t or don’t want to venture into a network server room to console into a Linux server. It is the most common way to access remote Linux and Unix-like servers. SSH, or Secure Shell, is a protocol used to securely log onto remote systems.

But, what exactly does this term mean and why is it important that every Linux user from novice to Linux Sysadmin know how to use it? If you are a Linux user, then you’ve probably heard of the term, SSH, or Secure Shell.
