WARNING: UNPROTECTED PRIVATE KEY FILE!
I got this error and I could not figure out the issue. Finally, I got something else that was not documented and frustrated me a lot. I was using my /home/thedbadmin/.ssh/config file for password less sftp. In place of the private key, I have mentioned my public key location inside the config file. I thought I will share this with everyone so that if they are using sftp password less connection using config file they can fix it fast.

Fix:
In my case, I have just change the file from rsa_thedbadmin.pub (public) to rsa_thedbadmin (private)
How should ‘~/.ssh/config’ look like
Host test_sftp_thedbadmin HostName pub.sftp.thedbadmin.com User user123 Port 22 IdentityFile /home/thedbadmin/.ssh/rsa_thedbadmin
Default Permission level for RSA public and private files. It should also need to be corrected.
1. Make sure you have private key path inside the ~/.ssh/config in case if you are using ~/.ssh/config
2. Change the ssh private and public key privilege according to the following permission.
RSA/DSA Private file permission: - rw------- = 600 RSA/DSA Public file permission : - rw-r--r-- = 644
I hope this will fix your issue. Comment in case you have any questions.
