Hi, noob to ntop (and most things pertaining to network analysis), so please
be gentle...

I'm interested in exploring the possibility of establishing a wireless
network connection between two buildings (this is not for me, but for a
friend's business).  I want to be able to evaluate the effectiveness of a
network link between a wireless router at the main building and a wireless
extender located at the second building (both off-the-shelf D-Link boxes).
I want to be able to log the connection speed over this link over an
extended period of time, so that I can see if weather conditions adversely
affect the link.  I want to do this for at least two weeks before I can
advise him if the link is sufficiently fast and reliable (I need to see if a
VOIP softphone is feasible in the remote location, so having a rock-solid
link is a necessity).

My question is twofold:

1) What program/tool would you use to generate a constant stream of
consistent traffic over the wireless link (in order to measure the speed
and/or reliability of the connection)? Would this require a dedicated
computer, or could a lightly-used "production" PC do the job without causing
it performance issues?  Would I also require another computer attached to
the extender at the other end, or can traffic be "received" by the wireless
extender alone?

2) (Assuming I can do step 1), is ntop the correct tool for analyzing and
logging this data?  If so, can you point me to any documentation on doing
so?  If not, any recommendations?

Looking forward to your responses.  Thanks.

Darren
