- Make RPC calls: rpcinfo allows users to make RPC calls to remote servers and report information about the services they provide.
- Querying remote services: rpcinfo can be used to query a remote server to determine which RPC services it provides, and to report information about those services, such as their version numbers, transport protocols, and endpoints.
- Troubleshooting: rpcinfo can be used to troubleshoot RPC-related issues by verifying that RPC services are running and that clients can connect to them.
- Simple and powerful: rpcinfo is a simple yet powerful tool that can provide valuable information about RPC services on a network.
