You can assign NFS permissions to any shared folder, allowing Linux clients to access it.
Security Flavors:
When accessing a shared folder via NFS with a specific user account:
- If AUTH_SYS security flavor is implemented: The client must have exactly the same numerical UID (user identifier) and GID (group identifier) on the NFS client and DiskStation, or else the client will be assigned the permissions of others when accessing the shared folder. To avoid any permissions conflicts, you can select Map all users to admin from Squash or give "Everyone" permissions to the shared folder.
- If Kerberos (krb5, krb5i, krb5p) security flavor is implemented: You must go to Win/Mac/NFS > NFS Service > Kerberos Settings > ID Mapping to map the NFS client to a specific user, or join a Windows /LDAP domain with the corresponding user account, otherwise the client will be assigned the permissions of guest when accessing the shared folder.
- If the file system of the external device on which shared folders are created is NTFS or FAT, the option Map all users to admin will be forcefully applied.
To use Kerberos security flavors to connect to the DiskStation, Kerberos authentication must be configured by going to Win/Mac/NFS > NFS Service > Kerberos Settings.
