This problem has been solved by Martin Stover (THANKS!!)

Title: ncpfs
|

Version: 2.0.10
|
||||
Entered-date: 23. February 1997

Version: 2.0.11

Description: With ncpfs you can mount volumes of your netware
|
||||
server under Linux. You can also print to netware
|
||||
print queues and spool netware print queues to the
|
||||
Linux printing system. You need kernel 1.2.x or
|
||||
1.3.71 and above. ncpfs does NOT work with any 1.3.x
|
||||
kernel below 1.3.71.
