    SSH Key Authentication

    I'm running a server where I have my SSH key set up with the root user so I can log in without the password.

    I also have an account called "jmaskell" that I use for everything, and I'm trying to add my SSH key to this. I've done exactly what I did for the root user and have my key in the .ssh/authorized_keys2 file. Unfortunately I'm still prompted for my password everytime I log in.

    Is it possible to have the same SSH key stored for two different users?

    The server is running CentOS 4 with OpenSSH 3.9.

    I've never tried it but if you look at the end of the private key it's usually [email protected], so I very much doubt that you can use one key for two different users. Just set up a second key.

    Follow the steps in the source server.

    Login as user

    press enter for all.
    copy the file content

    On destination server.
    Open a file named /home/username/.ssh/authorized_keys. Paste the content here. Check the permission of the files are like below.

    authorized_keys 600

    I'm unclear of what you're trying to do. Are you trying to log into the server as root from your jmaskell account, using a key for authorization? This is possible. You just need to generate your ssh key for jmaskell and add it to root's authorized_keys files.

    I'm guessing that if this is what you're trying that you have either made a typo in the key (the line wraps of a long public key usually mess me up), or you're logging in as the wrong user, or edited the wrong user's authorized_keys file.

    BTW, authorized_keys2 has been depecreated since openssh v3.0 (2001).
