Example:
# ListenPort <port-number>
ListenPort 111
ListenPort 2049
# SharePath <export-name> <local-name>
SharePath /share C:\MySharePath
# LogLevel <component> <level>
# <component> = net|rpc|nfs|...
# <level> = off|info|debug|warning|error
This NFS server supports all loaded programs (NFS/PORTMAP/MOUNT) on any listening port. This is because it doesn't take any extra code to support. Because of this, all the protocols could use the same port. Since PORTMAP is usually the first port that is connected to, it would make sense to have only one listen port on 111.
