Hi *,

Sorry for jumping into this mailing list but I do not know how to solve this.
RTFM did not work out and searching the list archives did not help either.

Situation:

We are using SuSE Linux 5.3 in our PC laboratory for about a year. Now it is
time to upgrade and I am in the progress of installing Debian potato on
the clients. Of course I installed version 2.2.12 on the clients. The
server is still running 2.0.37 and shall be converted when all clients
are upgraded.

Problem:

Many programs do not work anymore when run on a NFS volume (e.g. /home...).
They block in an SETLK call to fcntl. I need to get everything working
without upgrading the server to 2.2.x.

Question:

What can I do that locking is compatible with the 2.0 kernel installed before?
I found two postings about the same problem in the archive, one of them with
a patch to the kernel. But I do not want to patch the kernel for this little
problem - is there a way I can run a dummy lockd on the server or something?
Or is 2.2.x needed for rpc.lockd?

Thanks in advance
Torsten
