Applications on other computers access NetBIOS names over UDP, a simple OSI transport layer protocol for client/server network applications based on Internet Protocol on port 137. Determine operating system, computer name, netbios name and domain with the smb-os-discovery. NetBIOS names are 16 octets in length and vary based on the particular implementation. You can export scan results to CSV,. The script sends a SMB2_COM_NEGOTIATE request for each SMB2/SMB3 dialect and parses the security mode field to determine the message signing configuration of the SMB server. Alternatively, you may use this option to specify alternate servers. 4 Host is up (0. NetBIOS naming convention starts with a 16-character ASCII string used to identify the network devices over TCP/IP; 15 characters are used for the device name, and the 16th character is reserved for the service or name record type. In particular, ping scanning (TCP-only), connect scanning, and version detection all support IPv6.

These Nmap scripts default to NTLMv1 alone, except in special cases, but it can be overridden by the user. 1. By sending a HTTP NTLM authentication request with null domain and user credentials (passed in the 'Authorization' header), the remote service will respond with a NTLMSSP message (encoded within the 'WWW-Authenticate' header) and disclose information to include NetBIOS, DNS, and OS build version if available. Fixed the way Nmap handles scanning names that resolve to the same IP. Samba versions 3. nmap can discover the MAC address of a remote target only if. The simplest Nmap command is just nmap by itself. Example usage is nbtscan 192. --@param name [optional] The NetBIOS name of the host.
