I have an Amazon ec2 instance running, and I have a non-root user set

  • 0

I have an Amazon ec2 instance running, and I have a non-root user set up that I use to ssh.

I have both the private key and certificate stored on my ~. This is the command that I’m using to try and log in, but it prompts me for a password (which I don’t know/have).

$ sudo ssh -i mykey.pem root@ec2-amazoninstance.com
root@ec2-amazoninstance.com's password: 
Permission denied, please try again.

How do I log into root not knowing this password?

    On linux, once logged in as a user you use the command su to become root.

    To directly login into the root account you need to make sure

    • that you own the correct key or know the password
    • root login is enabled in the SSH server

    On a linux machine you would then run ssh root@ip to login as root on ip.
