WARNING: UNPROTECTED PRIVATE KEY FILE! when trying to SSH into Amazon EC2 Instance

Question

I\'m working to set up Panda on an Amazon EC2 instance. I set up my account and tools last night and had no problem using SSH to interact with my own personal instance, but

Answer 1

The private key file should be protected. In my case i have been using the public_key authentication for a long time and i used to set the permission as 600 (rw- --- ---) for private key and 644 (rw- r-- r--) and for the .ssh folder in the home folder you will have 700 permission (rwx --- ---). For setting this go to the user's home folder and run the following command

Set the 700 permission for .ssh folder

chmod 700 .ssh

Set the 600 permission for private key file

chmod 600 .ssh/id_rsa

Set 644 permission for public key file

chmod 644 .ssh/id_rsa.pub
