ssh keys from mac to ubuntu 12 lts

  • 772

I am attempting to set up a scenario in which I do not require to submit a password to ssh into an ubuntu machine from a mac. This is procedure i have been following:

1 - Open a terminal in your mac and remain logged in as you, not root.

2 - ssh-keygen (when asked for a password leave blank, the purpose of this s for rsync to be able to ssh without a password prompt)

3 - cat ~/.ssh/id_rsa.pub

This will have made an SSH key which will now be living in your home folder. Now you need to add the public key into the ubuntu VM

1 – Login as root into the vm

2 – mkdir /home/john/.ssh/

3 - nano /home/john/.ssh/authorized_keys copy the key generated on you mac into the ida_rsa.pub and paste into this file

4 – chown –R john /home/john/.ssh/

5 – chmod 600 /home/john

The result of this is, I have the key in both home directories. But when i ssh [email protected] i still get asked for a pword..

Any ideas?

Is there a config that must be setup in ssh within the ubuntu machine to allow this behaviour to happen?

    Here's the problem:

    chmod 600 /home/john

    You're making your home directory non-executable for yourself, which means that any process owned by you can't enter the directory to read its contents - including your ssh keys.

    You want chmod 700 /home/john instead. Also chmod 700 /home/john/.ssh; chmod 600 /home/john/.ssh/*
