SSH
located in ~/.ssh/config
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.
mkdir ~/.ssh chmod 700 ~/.ssh ssh-keygen -t rsa ssh-copy-id <username>@<host>
more information about setting up public/private key pairs
ssh config file:
host cl hostname cluster.illinois.edu user dlebauer
host is an alias to shorten logging in, e.g. by allowing
ssh cl
instead of
ssh cluster.illinois.edu
this also works in emacs
