- That's true by definition for most Unix documentation. The best
- documentation is the source code.
-
- The closest the man page comes is this (from rpc.mountd(8)):
-
- OPTIONS
- -n Do not check that the clients are root users. Though
- this option makes things slightly less secure, it does
- allow older versions (pre-3.0) of client NFS to work.
-
- What it doesn't say is how it checks that clients are root users. This is
- generally done by assuming that only root users can use ports below 1024
- (this is mentioned in the man pages for in.rlogind(8) and in.rshd(8), some
- other servers that also have to check that the client is setuid to root).

-
- I doubt there's much available about implementing NFS. You might want to
- get "Managing NFS and NIS" by Hal Stern, published by O'Reilly &
- Associates, for information about how NFS is used on workstations. Some of
- its troubleshooting information may help you understand how implementations
- interoperate.
