Creating new SSH keys

You can use SSH keys to connect between systems - and you can create these keys without passwords (to automate connections) or with passwords (more secure, since you need both the key and the password for the key).

For running jobs on Knot, you'll want to create a key to use locally, with no password (so your jobs can communicate)- do this by

ssh-keygen

then go to your ssh directory, i.e. "cd .ssh" and copy the 'pub' file into 'authorized_keys'.  If you already have an authorized_keys file for logins from other systems, you want to add to it, not overwrite it.  But here we're assuming you don't have that.

cp id_rsa.pub  authorized_keys

chmod 600 authorized_keys

That's it!
