SSH public key denied Kali Nethunter [closed]

am not able to ssh to Amazon AWS from my kali nethunter device nexus 6p I get this error public key denied.

However I can easily ssh from my desktop without any issues, computer that has kali linux directly installed.

Here is the error.

──(root💀kali)-[/sdcard/Download] └─# ssh -i kali-cloud.pem [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@@ Permissions 0660 for 'kali-cloud.pem' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. Load key "kali-cloud.pem": bad permissions ec2user@ec2-x-x -x.us-east-2.compute.amazonaws.com: Permission denied (publickey).

Kindly suggest.

Private keys should be go-rw and public keys should be go-w at least. In other words, permission 0660 is bad. chmod go-rw or 0600

Note also that the parent directory must also not be writable to anyone but the owner, so it should be 700 or 750

The reasoning here:

  • A private key is pretty useless if it is readable to others.
  • Both public key or private key are pretty useless if they can just be rewritten by others, either directly, or by replacing the file in the directory.

It would be a security hole to not ignore them when either of these is possible.
