RSA private key bad permission issue

  • fennng 

I recently migrated my website to a new server. When I tried to git push my website to git server from my new server, it failed, error as below.

fennng@fengUbuntu2:~/Dropbox/fengUbuntu/wp/html$ git push
Permissions 0644 for ‘/home/fennng/.ssh/id_rsa’ are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key “/home/fennng/.ssh/id_rsa”: bad permissions Permission denied (publickey).

and the repository exists.

The keys were copied from the old server. What’s wrong with it? Yes as it already stated. It’s the file’s permission. I used SFTP to copy the files over, but the permission was not set properly by the SFTP client. To fix this issue, we need to set proper permission for the id_rsa file.
