# rpcmap.py > Lookup listening MSRPC interfaces using a string binding (e.g., `ncacn_ip_tcp:host[port]`). > Part of the Impacket suite. > More information: . - Connect to an MSRPC interface using a string binding (e.g., `ncacn_ip_tcp:host[port]`): `rpcmap.py {{stringbinding}}` - Bruteforce UUIDs even if the MGMT interface is available: `rpcmap.py -brute-uuids {{stringbinding}}` - Bruteforce operation numbers (opnums) for discovered UUIDs: `rpcmap.py -brute-opnums {{stringbinding}}` - Bruteforce major versions of found UUIDs: `rpcmap.py -brute-versions {{stringbinding}}` - Specify a target IP address manually: `rpcmap.py -target-ip {{ip_address}} {{stringbinding}}` - Authenticate to the RPC interface with username and password: `rpcmap.py -auth-rpc {{domain}}/{{username}}:{{password}} {{stringbinding}}` - Authenticate using NTLM hashes for RPC: `rpcmap.py -hashes-rpc {{LMHASH:NTHASH}} {{stringbinding}}` - Enable debug output for verbose information: `rpcmap.py -debug {{stringbinding}}`
