DEBUG FLOW BASIC :
==================
Prepare the tool
1. undebug all - we are assuring that the debug utility is not already running.
2. get ffilter - we would expect to get no response. This tells us we have not set up any flow filters as of yet. If you should see filters listed you can delete them with unset ffilter.
Setup the capture
3. set ffilter src-ip x.x.x.x(computer A) dst-ip x.x.x.x(computer B)
set ffilter src-ip x.x.x.x(Computer B) dst-ip x.x.x.x(computer A) by doing this we can observe the packets flowing in each direction and where any possible problems may be. Basically we want to define the end points of communication.
Capture the traffic
5. clear db - this will clear the debugging cache.
6. debug flow basic - this turns the debugging utility on.
7. initiate the traffic you are interested in capturing.
Pull the data
8. undebug all - turns the utility back off.
9. get db stream - this is the actual packet capture output that we want.
Remove the setup
10.unset ffilter 0 - this will need to be done twice, once for each filter that we set up earlier.
11.clear db - this will clear the cache.
