When I SSH to VMWare ESXi server, there is no problem. sshpass -p 'my_password' ssh root@xxx.xxx.xxx.xxx
But when I try connecting via PHP script, an error appears: PHP Warning: ssh2_auth_password(): Authentication failed for root using password. I don't see "Authentication Successful!" nor "Authentication Failed" as defined in my PHP script. I tried SSHing to a different server (non-ESXi), thePHP script works without any problems. Here is my PHP script: <?php
$conn = ssh2_connect('xxx.xxx.xxx.xxx', 22);
if(ssh2_auth_password ( $conn, 'root', 'my_password')) {
echo "Authentication Successful!\n";
} else {
die("Authentication Failed...");
}
?>
I don't know if there is something wrong with my code, PHP SSH library, or something with ESXi server? Please help... |

This error could be because PHP doesn't have the privilege to connect to ESXi as root user. If that's the case, try logging into the ESXi server and execute the following commands to see if PasswordAuthentication is set to no. cd /etc/ssh
cat d| grep PasswordAuthentication
If it is no, set it to yes. If you don't have any text editors installed (which was my case), you can do the following: sed -i "s/PasswordAuthentication\ no/PasswordAuthentication\ yes/g" ./sshd_config
Restart the services. /sbin/services.sh restart
Now see if the PHP script connects to the server. |
