Setting up remote login

1. Let's first see if you have a remote key. Open a terminal and type more ~/.ssh/id_rsa.pub If a random string of letters and numbers appears, then you already have a public key and you can skip to step 3.
2. Don't have a public key? Let's make one! Open a terminal and type ssh-keygen to generate a public key. Just keep hitting enter. It's going to ask if you want to save the key to /Users/USER/.ssh/id_rsa and to make a passphrase. You want to save it to the default location and don't worry about the passphrase, just hit enter.
3. Copy the public key to the remove computer with the command ssh-copy-id USER@artemis.ldeo.columbia.edu What this is doing is copying your key to .ssh/authorized_keys on artemis.
4. Now you can log into artemis without a password. Try this ssh USER@artemi.ldeo.columbia.edu

Backup script

Now that we have remote login working, we can write a simple backup script that can use with crontab.

Setup keyless login

1. On local make an RSA key if you haven't already (ssh-keygen)
2. Copy that key into .ssh/authorized_keys on the first (i.e. bastion) server (ssh-copy-id user@first.server) 2b. Test that you can ssh user@first.server and connect without password
3. ssh to first.server and create an RSA key on first.server if you haven't already (ssh-keygen)
4. ssh-copy-id to the server you want to access (what I am calling second.server) 4b. test that you can ssh from first.server to second.server without entering a password

To copy from server to local

rsync -e "ssh user@first.server ssh" user@second.server:/path/to/file /path/to/local/dest
