| # How to login to a remote server without typing your password | |
| # ============================================================ | |
| # Create this folder if it does not exist: ~/.ssh | |
| mkdir ~/.ssh | |
| # Set the correct permissions (required) | |
| chmod 700 ~/.ssh | |
| # Generate an RSA key pair for identification with the remote server | |
| ssh-keygen -t rsa | |
| # Copy your public key to the remote server | |
| cat ~/.ssh/id_rsa.pub | ssh myserver.com 'cat >> ~/.ssh/authorized_keys' | |
| # ssh is very strict about correct permissions | |
| ssh myserver.com 'chmod g-w,o-w ~; chmod 700 ~/.ssh; chmod 600 ~/.ssh/authorized_keys' | |
| # Now you can connect to the remote server without typing your password | |
| ssh myserver.com | |
| # Create an alias for your server's address | |
| # (Use the alias with rsync, scp, ssh, etc.) | |
| alias=saturn | |
| user=carl | |
| host=myserver.com | |
| cat >> ~/.ssh/config <<END | |
| Host $alias | |
| User $username | |
| HostName $domain | |
| END | |
| # Now these two commands are equivalent | |
| ssh myserver.com | |
| ssh saturn | |
| # Connect to a login server called login | |
| # and then connect a second time to a work server called work | |
| # | |
| # cat ~/.ssh/config | |
| # | |
| # Host login | |
| # User simon | |
| # Hostname myloginserver.com | |
| # | |
| # Host work | |
| # User simon | |
| # ProxyCommand ssh -qX login nc %h %p | |
| # | |
| # Now you can connect directly to work from your laptop | |
| # | |
| # ssh work |
