* Generate the keys using the command ''ssh-keygen -t dsa'' and follow the prompts. If you're going to use the shared key to log into a system where user identities shouldn't be shared (i.e iVEC) save the key file as something like ''/home/observer/.ssh/id_dsa_username_galaxy'', and use a non-blank passphrase
  * scp the file to the target computer (which you want to be able to access using the shared key) with ''scp .ssh/id_dsa_username_galaxy username@galaxy.org:''
  * ssh into the target system (using your usual password) and include the shared key in the ''.ssh/authorized_keys file'' with a command like ''cat id_dsa_username_galaxy >> .ssh/authorized_keys''
  * You can now use the shared key to log in to the target system. If you want to avoid having to enter a password/phrase repeatedly, use ''ssh-agent bash'' and ''ssh-add .ssh/id_dsa_username_galaxy''. You'll have to enter your passphrase once this way.
