Opens your machine to attacks from $kriptkidd335?
Seriously, it's got something to do with NFS and NIS. I seem to recall some
coverage of it in one of my O'Reilly books. I will dig up the relevant Beast
tonight and bring it THU.
Oh, wait, garcia.efn.org is a SunOS machine, let me look at the manpages...

NAME
rpc - library routines for remote procedure calls
SYNOPSIS AND DESCRIPTION
RPC routines allow C programs to make procedure calls on
other machines across the network. First, the client calls
a procedure to send a request to the server. Upon receipt
of the request, the server calls a dispatch routine to per-
form the requested service, and then sends back a reply.
Finally, the procedure call returns to the client.
All RPC routines require the header <rpc/rpc.h> to be
included.
The RPC routines have been grouped by usage on the following
man pages.
portmap(3N) Library routines for the RPC bind ser-
vice, portmap(8C). The routines docu-
mented on this page include:
pmap_getmaps()

pmap_unset()
xdr_pmap()
xdr_pmaplist()
rpc_clnt_auth(3N) Library routines for client side remote
procedure call authentication. The rou-
tines documented on this page include:
auth_destroy()
authnone_create()
authunix_create()
authunix_create_default()
rpc_clnt_calls(3N) Library routines for client side calls.

rpc_clnt_create(3N) Library routines for dealing with the
creation and manipulation of CLIENT han-
dles. The routines documented on this
