Secure shell access
How to use ssh to access a Linux computer or wherever ssh is running
- What is ssh?
- Secure Shell is a network communication protocol that enables two computers to communicate and share data. SSH is often used to "login" and perform operations on remote computers but it may also be used for transferring data
- Graphics vs no graphics
- You can run something that will display graphical window(s) back but that requires a program that understands how to do that.
- First time connection
- You should be prompted the first time you connect to a remote computer to accept the remote computer's unique ssh key. If you are prompted again in the future to accept the ssh key for that same computer, it either means the computer has been rebuilt, this is your first time connecting from the computer you are using, or a hacker has taken control of the remote computer.
