Where are you doing this in the code? I'll go look at it and attempt a
fix. It's killing the server because the linkage fields are probably
not getting set. If NFSSERV is loaded, and the
links ever get hosed, you will get an Abend on 3.x and 4.x, and a
"process suspended" error on 5.x (which also hangs the server). If the
wrong pipe of fifo octals get set in mode,
it will also hang the server. If it is removing the entire namespace
with hardlinks, it's
also because these linkage fields are not getting set properly. It does
not work this way
with the NetWare NFSSERV.NLM mounted as an NFS client from Linux.

It should. It will allow you to use NDS with your existing code and NCP
suite. I guess
doug's next project at TRG will be to put in NDS support in NCPFS and
submit the patches to you.

There's some undocumented diagnostic calls in NDS that basically render
it totally unsuitable for the internet and make it easy to hack. It's
great for LANs in an organization where the
servers can all be locked up, and employees can get fired for hacking.
On the internet, it's
a piece of "swiss cheese" and is vulnerable in many respects.

You can expose these as .files the way HFS likes to see them, and MAC
clients to a Linux box
will be able to see and store their data in native MAC format -- with
finder info.
