Overview
This class provides the SMB server core. Settings that are relevant server wide are managed by this object. Currently, the server only supports negotiating and authenticating requests. No other server functionality is available at this time. The negotiating and authentication is supported for SMB versions 1 through 3.1.1.
Constant Summary collapse
- SUPPORTED_SERVER_DIALECTS =
The supported server dialects. SMB 1 is allowed, so that it can be reported as a failure to the user github.com/rapid7/metasploit-framework/issues/16261 Note there are similar supported dialects for both the server and the relay clients Msf::Exploit::Remote::SMB::Relay::NTLM::SUPPORTED_SERVER_DIALECTS and Msf::Exploit::Remote::SMB::Relay::NTLM::SMBRelayTargetClient::SUPPORTED_CLIENT_DIALECTS
