    29 {{{
     29{{{#!shell
    3030sudo apt-get update
    3131sudo apt-get install openssh-client

    3737 To create your public and private SSH keys, open a command-line terminal and type:
    38 {{{
     38{{{#!shell
    3939ssh-keygen -t rsa
    4040}}}
    4141 You will be prompted for a location to save the keys, and a passphrase for the keys which we highly recommend using. This passphrase does not have to be the same as your COSMOS account password.

    5555===== Uploading your public key to your COSMOS account
    5656 To upload you public key to your cosmos account, do the following:

    79 {{{
     79{{{#!shell-session
    8080ssh your_cosmos_username@gw.orbit-lab.org
