Which two parameters can be used to enable or disable guest access to Samba shares?

The focus for enabling or disabling guest access to Samba shares centers on the parameters that dictate the accessibility of a share without requiring authentication. The parameter "guest only" allows only guest access to the share, effectively disabling the need for any kind of user login. When set, it indicates that the share is meant exclusively for unauthenticated users, which enables guests to access the shared resources seamlessly.

This aligns with common configurations in Samba where administrators may want to provide open access to specific shares, often used for public data or resources. By contrast, other parameters like "guest ok" can allow guest access but also permit authenticated users, making "guest only" a more restrictive and clear option for purely public access. The "public" parameter could also relate to guest access but is less specific regarding its application compared to "guest only."

Therefore, using "guest only" sets a definitive approach to control access in a Samba configuration, reinforcing the intended behavior of the share to be limited solely to guest access.
