SSH authentication Issue

Also, I only allow the following:

KexAlgorithms [email protected],diffie-hellman-group-exchange-sha256
Ciphers [email protected],[email protected],[email protected],aes256-ctr,aes192-ctr,aes128-ctr
MACs [email protected],[email protected],[email protected],hmac-sha2-512,hmac-sha2-256,[email protected]

But since its ssh’ing to itself, you’d think it would work since the user itself can without issue.

I thought it did, the error message is being pulled from the section of code around Line 91 from https://github.com/wp-plugins/ssh-sftp-updater-support/blob/master/class-wp-filesystem-ssh2.php.

$rsa->loadKey($this->options['private_key']);

Is what lead me to believe this plugin supported SSH keys.

No problem. I use the standard rsa_4096 key generated by ssh-keygen. It is the same one I used to test internally with ssh, but as a different file with more open permissions so the webserver has permissions to access it.

I used the wp-config.php to define it, I even copied the private key and pasted it in the wordpress text area to test and it didn’t work.

define(‘FS_METHOD’, ‘ssh2’);
define(‘FTP_BASE’, ‘/var/www/wp-directory’);
define(‘FTP_PUBKEY’,’/home/wpsshupdate/.ssh/wp_rsa.pub’);
define(‘FTP_PRIKEY’,’/home/wpsshupdate/.ssh/wp_rsa’);
define(‘FTP_USER’,’wpsshupdate’);
define(‘FTP_PASS’,’******************hidden*******’);
define(‘FTP_HOST’,’localhost’);

I am using version 0.8.2.

The private key starts with:
—–BEGIN RSA PRIVATE KEY—–

The php user and the webserver are both using the custom user deploy, which has group access to read the /home/wpsshupdate/.ssh/wp_rsa file. This is a duplicate of the id_rsa file, but with more open permissions. The reason for that is the ssh server will not accept id_rsa for testing with group read permissions for the deploy user on it. I suppose I might get around this by having the deploy user be the ssh user, but I purposely set it up so that the deploy user cannot connect via ssh.
