说明
rpcinfo queries RPC servers and reports registered services. It is primarily used to diagnose RPC connectivity issues and view available network services like NFS, mountd, and other RPC-based services. The tool provides information about program numbers, versions, protocols, and ports for registered RPC services. It can probe specific services to check availability, broadcast to discover services on the network, and manage service registrations.
参数
- -p _host_
- Probe the portmapper on host and list all registered RPC programs.
- -s _host_
- Show concise table of all registered services.
- -m
- Display rpcbind operation statistics.
- -l _host_ _program_ _version_
- List all entries matching the given program and version.
- -t _host_ _program_ _version_
- Probe the service via TCP using an RPC call to procedure 0.
- -u _host_ _program_ _version_

- -b _program_ _version_
- Make an RPC broadcast and report all responding hosts.
- -d _program_ _version_ _transport_
