The version is 1.8:

# check_rpc plugin for nagios
#
# usage:
#    check_rpc host service
#
# Check if an rpc serice is registered and running
# using rpcinfo - $proto $host $prognum 2>&1 |";
#
# Use these hosts.cfg entries as examples
#
# command[check_nfs]=/some/path/libexec/check_rpc $HOSTADDRESS$ nfs
# service[check_nfs]=NFS;24x7;3;5;5;unix-admin;60;24x7;1;1;1;;check_rpc
#
# initial version: 3 May 2000 by Truongchinh Nguyen and Karl DeBisschop
# Modified May 2002 Subhendu Ghosh - support for ePN and patches
# current status: $Revision: 1.8

Curiously, if you look at the examples that the author includes for the 
checkcommand, you'll see that he does not include the -H for 
$HOSTADDRESS$. I have tried this but I get a usage error:

Usage:
 check_rpc -H host -C rpc_command [-p port] [-c program_version] [-u|-t] 
[-v]
 check_rpc [-h | --help]
 check_rpc [-V | --version]

Perhaps I'll try replacing the plugin, but by my logic that should not 
make a difference.
