Maybe you want to look at LIMITATIONS in README. Some might consider
them to be bugs.
But there are really problems that might be fixed in the future.
Invalid directory timestamps:
I did not yet find out how to get valid timestamps for directories
from a NetWare server. So I simply return 0, which means 01.01.70. If
anybody knows how to get these values, please mail
lendecke@namu01.gwdg.de.
'df' returns 0:
Free disk space is distributed among the volumes in NetWare. df is
only able to report one number per mounted filesystem. As connections
are quite expensive for NetWare (with lwared that might change ...), I
rejected the alternative to mount only a single volume for a unix
mount point. So I simply return 0.

ncpfs-0.2 -> ncpfs-0.3
- removed bug in get_pname_static
- removed bug in 'ncpmount -n'
- fake '.' and '..'
- return 0 for df and directory timestamps. See file BUGS
ncpfs-0.1 -> ncpfs-0.2
- should be compileable with gcc other than 2.7.0

much harm to their business. For your convenience I included the file
ipx.tar made available by Caldera.
For the curious: the file ncplib.c is usable from user space as well!
Look at the file ncptest.c for a possible use. I use ncptest to check
my assumptions about the widely undocumented NetWare Core
Protocol. Maybe this is the beginning of a free NetWare API for Linux!
I would be happy to receive your comments on this.
My main source of information is a book written in german by Manfred
Hill and Ralf Zessin, "Netzwerkprogrammierung in C", IWT Verlag GmbH,
1995, ISBN 3-88322-491-X. It contains quite a lot of typographical and
other errors, but I find it very valuable as an introduction to NCP
programming. If you know about the concepts and possibilities of NCP,
Ralph Brown's interrupt list becomes much more readable. It's much
easier to find undocumented information if you know what to look for!

MAILING LIST
There is a mailing list for discussing lwared and ncpfs. Here's the
message I received after subscribing:
---
Thank you for your subscription to the list "linware".
Topics for the list:
- discussing LinWare server, its features, installation problems and bugs
- using IPX protocol under Linux
- IPX routing and router daemons under Linux
