| ===public/private keys===
| |
| Setting up public and private keys allows logging in without use of a password. This simplifies login, and it also enables processes to be automated, for example rsync, or sending commands from one server to another. This is actually very simple to do.
| |
|
| |
| <pre>
| |
| mkdir ~/.ssh
| |
| chmod 700 ~/.ssh
| |
| ssh-keygen -t rsa
| |
| ssh-copy-id <username>@<host>
| |
| </pre>
| |

| ===ssh config file:===
| |
| To make logging in easier, especially when your login name is different on your computer and the remote computer, I first set up my ssh config file with an alias to the remote address
| |
|
| |
|
| |
| here is an example of an ~/.ssh/config file:
| |
|
| |
| <pre>
| |
| host cl
| |
| hostname cluster.illinois.edu
| |
| user dlebauer
| |
| </pre>
| |
|
| |
| this allows logging in with the command
| |
| <pre>ssh cl</pre>
| |
| instead of <pre>ssh cluster.illinois.edu </pre>
| |
|
| |
| This alias (in this case, 'cl') can also be used from emacs and other programs that use ssh.
