setuid bit in VMS-ULTRIX-CONNECTION UCX files

[Dietmar Weis]

UCX is an implementation of TCP/IP services on DEC VMS systems.

It includes a complete NFS-server, which exports the original VMS files
to the Unix client as well as an "Ultrix Container File System CFS",
which exports an Ultrix FS on the VMS disk. It is created and maintained
by the VMS server with a couple of commands, newfs- and fsck-like.
Every Unix file on the client is a VMS file on the server, the
file system structure is represented in a special file, the container file.
On the client side it is, of course, fully transparent.

Now the question:

Is it possible to set the suid/sgid bits to files in the CFS ??

I did eg. a chmod 6555, which  results only in 555, neither the server
nor the client reported an error.

Does the server/CFS only know the ordinary 9 permission bits ?
Have I to reconfigure the server (but where) ?
Is it impossible ?

The guys at DEC Support weren't quite shure about that, so is there
anyone on the net, who knows it more exactly?

I' m using Ultrix 3.1, UCX 1.2 patched, VMS 5.3 on MicroVAX.

Any help is wellcome, Dietmar
