Generate A SSH Key Pair
SSH Key pairs are a simple and secure way to access Lewis. A SSH key pair contains
a private key and a public key. You will keep your private key to on your computer
or a USB key.
Step 1
On the computer you want to use to access Lewis, open your terminal app.
Then type the following command:
ssh-keygen
When prompted press enter to save the key in the default location
(/home/<username>/.ssh/id_rsa) then enter a strong passphrase (required) twice.
After you generate your key you will need to display the public key
and include it in the Account Request Form. Type the command:
cat ~/.ssh/id_rsa.pub
The output will be a unique string of random characters similar to this:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7iKBE2qsnnR+mguxvvKNyj/IJchBjba4QD39BGMCC

We recommend that you copy your SSH key pair to a USB drive so you can log in to
Lewis from more than one computer. Replace the the path below in the example to
the actual path to your USB drive:
mkdir /some/path/to/usb_drive/ssh_key_backup/
cp ~/.ssh/id_rsa* /some/path/to/usb_drive/ssh_key_backup/
ls /some/path/to/usb_drive/ssh_key_backup/
