Detailed Interface
Events
-
netbios_session_accepted Type: event(c:connection, msg:string)Generated for NetBIOS messages of type positive session response. Bro’s NetBIOS analyzer processes the NetBIOS session service running on TCP port 139, and (despite its name!) the NetBIOS datagram service on UDP port 138.
See Wikipedia for more information about NetBIOS. RFC 1002 describes the packet format for NetBIOS over TCP/IP, which Bro parses.
C: The connection, which may be TCP or UDP, depending on the type of the NetBIOS session. Msg: The raw payload of the message sent, excluding the common NetBIOS header. See also:
netbios_session_keepalive,netbios_session_message,netbios_session_raw_message,netbios_session_rejected,netbios_session_request,netbios_session_ret_arg_resp,decode_netbios_name,decode_netbios_name_typeNote
These days, NetBIOS is primarily used as a transport mechanism for SMB/CIFS. Bro’s SMB analyzer parses both SMB-over-NetBIOS and SMB-over-TCP on port 445.
Todo
Bro’s current default configuration does not activate the protocol analyzer that generates this event; the corresponding script has not yet been ported to Bro 2.x. To still enable this event, one needs to register a port for it or add a DPD payload signature.

netbios_session_keepalive Type: event(c:connection, msg:string)Generated for NetBIOS messages of type keep-alive. Bro’s NetBIOS analyzer processes the NetBIOS session service running on TCP port 139, and (despite its name!) the NetBIOS datagram service on UDP port 138.

-
netbios_session_message Type: event(c:connection, is_orig:bool, msg_type:count, data_len:count)Generated for all NetBIOS SSN and DGM messages. Bro’s NetBIOS analyzer processes the NetBIOS session service running on TCP port 139, and (despite its name!) the NetBIOS datagram service on UDP port 138.
See Wikipedia for more information about NetBIOS. RFC 1002 describes the packet format for NetBIOS over TCP/IP, which Bro parses.
C: The connection, which may be TCP or UDP, depending on the type of the NetBIOS session. Is_orig: True if the message was sent by the originator of the connection. Msg_type: The general type of message, as defined in Section 4.3.1 of RFC 1002. Data_len: The length of the message’s payload. See also:
netbios_session_accepted,netbios_session_keepalive,netbios_session_raw_message,netbios_session_rejected,netbios_session_request,netbios_session_ret_arg_resp,decode_netbios_name,decode_netbios_name_typeNote

C: The connection, which may be TCP or UDP, depending on the type of the NetBIOS session. Is_orig: True if the message was sent by the originator of the connection. Msg: The raw payload of the message sent, excluding the common NetBIOS header (i.e., the user_data).See also:
netbios_session_accepted,netbios_session_keepalive,netbios_session_message,netbios_session_rejected,netbios_session_request,netbios_session_ret_arg_resp,decode_netbios_name,decode_netbios_name_typeNote
