--- Comment #10 from kpielorz@tdx.co.uk ---

Hi,

I've just run into this issue under FreeBSD 10 - rpcbind '-h' provides a false
sense of security, as by default although some of the ports it sets up do
indeed bind to the requested IP - there's one or more random ports opened on
UDP - that ignore the '-h' IP address, and are open to the world.

Is anyone able to look at this - this PR seems pretty ancient (filed in 2007,
and the issue still kicking along in 2014? - 7 years?).

As the ports opened are random they are also hard to protect with ipfw - so all
in all, it's a bit of a PITA :(

At the very least can someone flick it from 'Normal Affects Only Me' to
'Affects a Few people'?

-Karl
