 I have been having trouble with Suns lock daemon and BWNFS (client NFS for the
PC). The original version of rpc.lockd which comes will Sun(4) OS 4.0.1 
(~64000 bytes) didn't support the DOS 3.1 locking extensions. It returned
"garbage args" for lock and share requests. I mentioned this to Sun and
Geoff Arnold sent me a version (~139000 bytes) dated August 11,1989 which
seems to work correctly. This version works with Sun's PC-NFS and BWNFS.
I just received a sniffer trace of a rpc.lockd (~180000 bytes) which a user
aquired from Sun last month. This lock daemon seems to work correctly for
LOCK, UNLOCK and SHARE, but UNSHARE returns the dreaded "garbage args".
According to nlm_lock.x the arguments to SHARE and UNSHARE are identical.
Has Sun changed the specification ? Is this new version faulty ? Has
anyone had problems with file sharing under PC-NFS 3.x with a lock daemon
of the specified size ?

Any comments, sugestions welcome.
