| DCERPC::ReadTimeout | The number of seconds to wait for DCERPC responses |
| MaxGuessesPerService | Maximum number of credentials to try per service instance. If set to zero or a non-number, this option will not be used. |
| MaxGuessesPerUser | Maximum guesses for a particular username for the service instance. Note that users are considered unique among different services, so a user at 10.1.1.1:22 is different from one at 10.2.2.2:22, and both will be tried up to the MaxGuessesPerUser limit. If set to zero or a non-number, this option will not be used. |
| MaxMinutesPerService | Maximum time in minutes to bruteforce the service instance. If set to zero or a non-number, this option will not be used. |
| NTLM::SendLM | Always send the LANMAN response (except when NTLMv2_session is specified) |
| NTLM::SendNTLM | Activate the 'Negotiate NTLM key' flag, indicating the use of NTLM responses |
| NTLM::SendSPN | Send an avp of type SPN in the ntlmv2 client Blob, this allow authentification on windows Seven/2008r2 when SPN is required |
| NTLM::UseLMKey | Activate the 'Negotiate Lan Manager Key' flag, using the LM key when the LM response is sent |
| NTLM::UseNTLM2_session | Activate the 'Negotiate NTLM2 key' flag, forcing the use of a NTLMv2_session |
| NTLM::UseNTLMv2 | Use NTLMv2 instead of NTLM2_session when 'Negotiate NTLM2' key is true |
| Proxies | Use a proxy chain |
| REMOVE_PASS_FILE | Automatically delete the PASS_FILE on module completion |
| REMOVE_USERPASS_FILE | Automatically delete the USERPASS_FILE on module completion |
| REMOVE_USER_FILE | Automatically delete the USER_FILE on module completion |
| SMB::ChunkSize | The chunk size for SMB segments, bigger values will increase speed but break NT 4.0 and SMB signing |
| SMB::Native_LM | The Native LM to send during authentication |
| SMB::Native_OS | The Native OS to send during authentication |
| SMB::VerifySignature | Enforces client-side verification of server response signatures |
| SMBDirect | The target port is a raw SMB service (not NetBIOS) |
| SMBName | The NetBIOS hostname (required for port 139 connections) |
| SSL | Negotiate SSL for outgoing connections |
| SSLVersion | Specify the version of SSL that should be used (accepted: SSL2, SSL3, TLS1) |

| ShowProgressPercent | The interval in percent that progress should be shown |
| WORKSPACE | Specify the workspace for this module |
| DCERPC::fake_bind_multi | Use multi-context bind calls |
| DCERPC::fake_bind_multi_append | Set the number of UUIDs to append the target |
| DCERPC::fake_bind_multi_prepend | Set the number of UUIDs to prepend before the target |

| SMB::obscure_trans_pipe_level | Obscure PIPE string in TransNamedPipe (level 0-3) |
| SMB::pad_data_level | Place extra padding between headers and data (level 0-3) |
| SMB::pad_file_level | Obscure path names used in open/create (level 0-3) |
| SMB::pipe_evasion | Enable segmented read/writes for SMB Pipes |
| SMB::pipe_read_max_size | Maximum buffer size for pipe reads |
| SMB::pipe_read_min_size | Minimum buffer size for pipe reads |

| SMB::pipe_write_min_size | Minimum buffer size for pipe writes |
| TCP::max_send_size | Maxiumum tcp segment size. (0 = disable) |
| TCP::send_delay | Delays inserted before every send. (0 = disable) |
