Installation
• 1. Install NetHawk SW– Start installation program (setup.exe)– Give the license holder’s name– Give the register number– Give the product key (12 characters CASE sensitive) – Give the next product key if further keys are requested
• 2. Insert adapter• 3. Start NetHawk program• -> You have a working NetHawk program
15
Checking the HW installation on Windows 98/2000

Interface card connected to software?
• SW has found the adapter if:
– Scanner menu item can be selected
– State Monitor menu item can be selected
– HW related fields can be selected in the Tools|Options menu

The list of up to 5 lately opened files.
22
Edit and Monitor menus

Monitor menu items:
23
Setup connections
In "Setup Connections" window you can choose the source of the monitored traffic and activate the connections of the Nethawk analyser.
24
Setting up AAL2/FP connections
25
Setting Layer Details
In "Layer Details" window you can choose the detail levels and coding settings of the protocol layers. These settings affect the way the analysed messages are shown in the Monitoring window.
26
Saving Configuration to a file
The configuration file contains information about the connections (timeslots, protocol stacks) and the decoding settings (detail level, coding and colors) of the protocol layers.
27
Open Trace file
Use the "Open Trace File" window to choose the trace file for analysing recorded traffic. Pick the trace file (.grc) from 'Name" list box.
28
Saving the traffic: Save history buffer
Insert description of the traffic analysed.
Save the configurations made with the trace file.
Trap file can be connected to the trace when saving the trace file.
29
Controlling Protocol Analysis with Traps
30
Introduction to Trap window
• Activate / Deactivate Trap
• Condition• Action• Continuous or one
shot triggering• Count before action• Protocol, message
and IE selection• Copy trap• Save trap• Open saved trap• Helps
31
Storing Trap definitions to disk for later use
• You can save your current trap definitions to file from Trap definition dialog
32
Example 1: Filter In / Out
• Filter in is used to show only defined event(s) in the screen where the traffic is viewed. Filter Out hides defined message(s) from the screen.
• Filter in is good trap for testing the condition. When condition is set and Filter In action is selected, the condition’s functioning can be checked easily from the decoding window.
• Filter out hides the messages with matching condition from the screen. Messages can be hidden by inactivating connection and/or setting layer details different.
• In this example, the content sensitive trapping is also tested.
33
Example 1: Filter In / Out, steps
1. Select message in the analyser display.2. Press mouse right button and select define trap. The trap is
automatically created.3. Change Action to be triggered to filter out.4. Change Triggering to continuous.5. Activate the trap by checking activation checkbox6. Press OK7. See that the messages which you defined are not seen
anymore.8. You can test similar thing with Filter in action. You should
see only defined messages.
34
Example 1: Filter In / Out, steps
35
Typical Trap case: Filter In
36
Using Protocol Help in defining traps
• When creating complex traps to contents of certain information elements, you can refer to Protocol Help, by pressing Protocol Help button in Trap definition dialog
• Typically you have to check that “Hex value” and “Offset” -fields are correct in “Compare value” section of your trap definition dialog according to the protocol specification
• Context sensitive Protocol Help can be activated also from history mode by pressing: CTRL+F1
