% man lockf

NAME
     lockf - record locking on files

     File region locking is supported over NFS, if the NFS lock-
     ing service has been enabled.

Seems a bit contradictory, doesn't it.  Have you used nfssetlock to enable
NFS locking service?  (Apologies if this is too obvious--I'm still a novice
at managing Ultrix systems.)
