Let's see... for one who is asking for help, one has a very windows-centric
view of the world and also is quite demanding...  Especially to the
individual who is offering (or was offering) his personal work product to
solve your perceived need.

WRT to your PS: The entire world does not use only a single mail client.
Take risks.  Live a little.   BE FLEXIBLE WHEN YOU ARE ASKING FOR HELP.  If
you are paying somebody for their work, you have the right to specify the
format.  Otherwise, the onus is upon you <insert preferred derogatory word>.

WRT to your PPS: Actually, proper net-etiquette is to put one's comments at
the BOTTOM of the message so the whole thing flows like water.

Of course the problem with leaving the various generations of messages in
the text is that your lame email program breaks at 75, but when it then
prefixes the 75 character line with "> ", it now breaks it into two:

> Hello There

becomes
> >Hello
> There

So once again, be careful of applying the actions and conventions of a
single email client program to the entire world.  Much like not everyone
speaks English, not every mail program works the same way...


We now return you to your question:


If you were to have read the docs/FAQ (the current, 3.0 version, that is),
there are discussions about ntop's memory usage - it's NOT dependent upon
the # of machines in your network, but rather dependent upon the # of hosts
ntop see packets to/from.  That is upon the # of hosts contacting your
network + the # of hosts being contacted by hosts on your network.  Your
Kazza request hits 1000 servers?  That 1000+1 (your local machine) hosts.
Etc.

There are switches and filters you can use to limit this, all discussed in
docs/FAQ.

READ IT.
