I have the task of service validation in a service scanning program.
I am having a hard time getting or soliciting any NetBIOS Datagram
(netbios-dgm) response from UDP port 138.
I need to be able to send a data packet to UDP 138 or any UDP/TCP
port and get a NetBIOS Datagram out of UDP 138.
I can only seem to get a broadcast NetBIOS Datagram. Not sure if it
broadcasts on an interval. Does UDP Port 138 listen only? Does it
send a netbios-dgm in response to some event?
If there is a query I can send what it is? Does anyone have a TCP
Dump of such a packet?
I took apart the Samba source and duplicated the cli_send_mailslot
functionality but still I can not get a response.
Samba group has been sending and decoding NetBIOS data for a while so
I am hoping someone can help.
ThanX in advance
Erik
