HEIDENHAIN CIMCO NFS Bedienungsanleitung Seite 2

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 ex-
ports. 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 dif-
ferent 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 ac-
cess the folder can not modify or delete any files in the exported folder.
Security
It's not recommended to start the NFS Server on a computer on a network connected
to the Internet, without specifying an access control list. Othervise 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 NT/2000/XP/Vista/Server/
and access files located on a Novell Netware server, there is one point to note regarding
log-ins. 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 NT computer.
The solution is to create a local Windows NT login with the same username and pass-
word 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.
