rpc
The rpc map is the the abbreviated name for the rpc.bynumber map. The derived maps are rpc.byname and rpc.bynumber. In most cases, the rpc map is created from the /etc/rpc file. A typical line looks like this:
rpc_name port_number alias1 alias2 ... # comment
For example:
portmapper 100000 portmap sunrpc rpcbind 100001
For the rpc.byname map, entries are defined like this:
- Key is the rpc name or alias, so there would be separate entries for: portmapper, portmap, sunrpc, and rpcbind.
- Value for each of the portmapper, portmap, and sunrpc key entries would be the same: portmapper 100000 portmap sunrpc
For the protocols.bynumber map, entries are defined like this:
- Key is the rpc number: 100000
- Value is the rpc name, number, and aliases: portmapper 100000 portmap sunrpc
If you create a rpc map in Active Directory, you must include the key as part of the value. For example:
- Key: portmapper
- Value: portmapper 100000 portmap sunrpc
- Comment: portmap and sunrpc are aliases for portmapper
