I want to copy files from a local machine to a remote machine.

I have the command all set up and it looks like this:

rsync -a project root@123.456.789.0:~

However, when running this command, I'm prompted with a message to enter the remote server's password.

When setting this up as a cronjob it fails because the password is not entered.

What is way around this? How can I create my cron job to run the command and enter in the password?

You can use public key authentication: on the server, add a line with the command run by rsync (for security) and your public key to ~root/.ssh/authorized_keys. See the sshd(8) man page for information on the authorized_keys file format.

  • Oops, did the opposite. – Noah Matisoff Oct 7 '14 at 21:31
