rsync using keygen login in bash script

  • 772

So I have set up a password-less ssh login for a server. I can run rsync from the command line, and it works beautifully, and doesn't ask me for a password:

rsync -avz -e ssh myDir [email protected]:/place/myDir

However, when I put this in a bash script and execute the script, it stops to ask me for a password.

#!/bin/bash

rsync -avz -e ssh myDir [email protected]:/place/myDir

Why is this happening? What should I look for to stop this?

ssh

    You may need to add the path to your identity file like this:

    rsync -avz -e "ssh -i /home/user/.ssh/id_rsa" myDir [email protected]:/place/myDir

  2. You need to source your ssh agent. I use keychain for this.

  3. I like to set up ssh configurations in a configuration file - ~/.ssh/config

    It looks like this

    Host xxx-master
HostName X.X.X.X
User user
IdentityFile ~/.ssh/xxx_id_rsa
ControlMaster yes
ControlPath ~/.ssh/xxx_ctrl_path

Host xxx
HostName X.X.X.X
User user
ControlPath ~/.ssh/xxx_ctrl_path

    Then I ssh xxx-master and it asks me for the passphrase. While I continue to be logged into xxx-master, I can ssh xxx without a passphrase.

    Is this better than ssh agent? I don't know. I use this method because I have not figured out ssh-agent.
