great it works! thanks itkamaraj.
I add the following line and specify only the specific script.

You can log or execute commands as another user using ssh:
ssh host -p 22 -l remote-user -q "command args"

To bypass password, generate a key par for the guest account:
ssh-keygen -t rsa

And append the contents of ~/.ssh/ in the guest account to the file ~/.ssh/authorized_keys in the host account in the remote server.

For troubleshooting look at /var/log/secure with a privileged user.

Editing "/etc/sudoers" as below is a security risk, as "username" can impersonate anyone, even root.
