HP-UX IPFilter Version 15.01 Administrator's Guide

By default, all RPC rules are configured as the first rules, for example, RPC_RULE_POSITION=1.
The RPC rules are well defined in terms of IP addresses and ports and will have unique matches
and, since they are quick rules, they should be at top.
RPC Rules Configuration File
This file specifies details based on which IPFilter RPC rules will be generated.
/etc/opt/ipf/rpc.ipf/rpc_ipfconf.sample is provided as an example.
The /etc/opt/ipf/rpc.ipf/rpc_ipfconf file contains the client list and program list. The
sample file grants access to the program numbers listed from the IP addresses and IP subnets
listed in the client list.
The example shown in the sample file lists the program numbers used by an NFS server,
rpc.mountd, rpc.statd, rpc.lockd, and nfsd. This file also has the following declared:
ADD_RPC_IPFILTER_RULES=1
Set this to 1 to configure RPC IPFilter rules.
RPC_RULE_POSITION=1
Must be 1 or greater, as noted in the previous section.
RPC_RULES_FILE=./rpc.rules
This is the path to the RPC rules file, which contains the rules to be added or deleted.
