The best way to do this is with access control lists. What you do is put an acl on the file that grants access only to users with the (for example) VAX785 identifier. Then, at boot time you run a simple little program that adds a system-wide identifier to the proper VAX. Every user on that VAX will then have that identifier, while users accessing the file from another on the cluster will not. There was an excellent example of just such a program on the notes that went with Mark Pilant's (I think) talk on ACLs at the last DECUS. Anyone remember the code? /Kevin Carosso engvax!kvc @ CIT-VAX.ARPA Hughes Aircraft Co.
