Networking with NFS and CNC Machines

The CIMCO NFS Server enables a CNC machine to access the files in a shared folder on a server, using a standard network. The shared folders on the server are called exports. When a CNC machine connects to the NFS Server, it must specify which export to use. If the CNC machine is allowed to access the export, it can read and (if allowed) write to the files in the exported folder.

The NFS Server can handle multiple exports, so it is possible to export more than one folder on the same computer. It is also possible to export the same folder with different export names and access rights. This way, you can create a setup where some machines have read access to the exported folder while other machines have both read and write access.

Access Control

You can configure the IP addresses of the machines that are allowed to access each export. If you do not specify any IP addresses, all machines are allowed access. Furthermore, it is possible to make an export read-only, where the machines that access the folder cannot modify or delete any files in the exported folder.


It is not recommended to start the NFS Server on a computer on a network connected to the Internet, without specifying an access control list. Otherwise, it may be possible for intruders on the Internet to access the exported files.

Novell Netware

If you plan to run CIMCO NFS Server on a Windows® computer and access files located on a Novell Netware server, there is one point to note regarding logins. To have access to Novell resources, the NFS service has to run with a login that is valid on the Novell server, but because of the tight relationship between services and the Windows® user database, this login also has to be present on the Windows® computer.

The solution is to create a local Windows® login with the same username and password as the (remote) Novell login. The service will now be able to start without problems, and requests to the Novell server will come from a valid username and password.
