nfs mount fails

Hi,

I’m trying to mount an NFS file system (on AIX4) from QNX4.
It works from other AIX machines.
The output:

mount -t nfs 10.2.0.1:/testdir /tmp/wolf

mount: Can’t mount /tmp/wolf (type nfs)
mount: Possible reason: Permission denied

On AIX I got a similar error before changing the ownership of the target
directory to bin:bin.
That didn’t work out on QNX.
If anybody has an idea where I could set the Permissions…


thanks in advance
Sascha
