When I saw this a few weeks ago on SNI's web page (it wasn't published
as an advisory, it was published as one of the checks their Ballista tool
performs) I was intrigued, so I sat down and spent some time trying
to exploit this.

By modifying rpcinfo.c to connect to port 32771 and changing the
PMAPPROC_DUMP stuff to work over UDP instead of TCP (clntudp_create),
you can get nicely functional "over-the-packet-filter" rpc dump.

If there's interest, I'll post diffs.

Now the *real* trick is figuring out how to get Solaris NFS to give up
its export list over another high-numbered port..
