|
Netmon allows a programming interface to insert frames into a running capture.
|
|
There are two different ways to do this. You can either used the defined
|
|
interfaces in the NMExt API suite to start the capture, define the filter etc,
|
|
or you can use the "raw" interface. Using this interface will insert a frame
|
|
into EVERY running capture. For example, if you your two different Netmons
|
|
running, one on ethernet and one on FDDI, you will get the inserted frame
|
|
into both captures.
|
|
Calling TransmitSpecialFrame if Netmon is not running is just fine. Nothing
|
|
will happen, the data will just be dropped.
|
|
|
|
The entry point defined below (TransmitSpecialFrame) is contained in NAL.DLL.
|
|
NT4.0 is the first version of NT that contains the entry point, specifically
|
|
build 346.
|
|
|
|
NOTE NOTE NOTE: You should NOT link to the NAL.LIB to acquire this
|
|
functionality. NAL.DLL is not gaurenteed to be installed on a standard NT
|
|
machine. Instead use Loadlibrary to acquire the entry point.
|
|
|
|
When a frame is inserted, a fake media header and parent protocol is created
|
|
for your data. We create a "TRAIL" protocol header that hands off to your
|
|
data. The parsing of your data depends on the FRAME_TYPE_ that you specify.
|
|
If you specify a known frame type, we will parse it for you. For example, the
|
|
FRAME_TYPE_MESSAGE uses a data structure that looks something like this:
|
|
|
|
typedef struct _MessageFRAME
|
|
{
|
|
DWORD dwValue1;
|
|
DWORD dwValue2;
|
|
CHAR szMessage[];
|
|
} MessageFRAME;
|
|
|
|
Just fill out one of these and point to it when you call TransmitSpecialFrame
|
|
with the FRAME_TYPE_MESSAGE.
|
|
FRAME_TYPE_COMMENT is just an array of printable chars. If you want to make
|
|
your own data structure, pick a number above 1000 and use that number as the
|
|
FrameType parameter. Note that you must add your number and parser name to
|
|
the TRAIL.INI file in the Netmon parsers directory.
|
|
|
|
Example:
|
|
|
|
setup:
|
|
TRANSMITSPECIALFRAME_FN lpfnTransmitSpecialFrame = NULL;
|
|
|
|
hInst = LoadLibrary ("NAL.DLL" );
|
|
if (hInst)
|
|
lpfnTransmitSpecialFrame = (TRANSMITSPECIALFRAME_FN)GetProcAddress ( hInst, "TransmitSpecialFrame" );
|
|
|
|
if (( hInst==NULL ) || ( lpfnTransmitSpecialFrame==NULL) )
|
|
{
|
|
...
|
|
}
|
|
|
|
usage:
|
|
lpfnTransmitSpecialFrame( FRAME_TYPE_COMMENT, 0, (unsigned char *)pStr, strlen(pStr)+1 );
