Configuring portmap
-------------------
Portmap by default listens to all IP addresses. However, if you are not providing network RPC services to remote
clients (you are if you are setting up a NFS or NIS server) you can safely bind it to the loopback IP address
(127.0.0.1)
This will allow RPC local services (like FAM) to work properly, while preventing remote systems from accessing your
RPC services.
You can also change this configuration by editing the OPTIONS line in the /etc/default/portmap file. If you just don't
specify the -i option it will bind to all interfaces.
Should portmap be bound to the loopback address?
