It's the standard nfsd which comes with SuSE 6.0:
=== atlas:/home/baulig > /usr/sbin/rpc.nfsd --version Universal NFS Server 2.2beta38 atlas:/home/baulig > /usr/sbin/rpc.mountd --version Universal NFS Server 2.2beta38 atlas:/home/baulig > rpm -q --file /usr/sbin/rpc.nfsd nkita-98.12.14-5 ====
I tried to mount the filesystems with the 'nolock' option and it works fine now.
Thanks for your help!
