of a worry. So use ipchains on Linux or ipfilter on most anything, and set up
the host to block all but select, chosen protocols at its interfaces.

This, of course, assumes that you don't ever intend to run NFS.

And if the machine was *running* the automounter, there's only 2
explanations:

1) It was started by default and the machine was never tightened down.
2) There is actually a desire to use NFS.

Unless you have an ipchains or ipfilter that's smart enough to
reject based on the RPC procedure number, you're stuck.
