Don't use a password. Generate a passphrase-less SSH key and push it to your VM.
If you already have an SSH key, you can skip this step…
Just hit Enter for the key and both passphrases:
$ ssh-keygen -t rsa -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/home/username/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/username/.ssh/id_rsa.
Your public key has been saved in /home/username/.ssh/id_rsa.pub.
Copy your keys to the target server:
$ ssh-copy-id id@server
id@server's password:
Now try logging into the machine, with ssh 'id@server', and check-in:
.ssh/authorized_keys
Note: If you don't have .ssh dir and authorized_keys file, you need to create it first
to make sure we haven’t added extra keys that you weren’t expecting.
Finally, check to log in…
$ ssh id@server
id@server:~$
You may also want to look into using ssh-agent if you want to try keeping your keys protected with a passphrase.
I needed to have rw for user only permissions on config. This fixed it.
chmod 600 ~/.ssh/config
As others have noted below, it could be the file owner. (upvote them!)
chown $USER ~/.ssh/config
If your whole folder has invalid permissions here's a table of possible permissions:
| Path |
Permission |
| .ssh directory (code) |
0700 (drwx------) |
private keys (ex: id_rsa) (code) |
0600 (-rw-------) |
config |
0600 (-rw-------) |
public keys (*.pub ex: id_rsa.pub) |
0644 (-rw-r--r--) |
authorized_keys (code) |
0644 (-rw-r--r--) |
known_hosts |
0644 (-rw-r--r--) |
