I had continual problems with FreeBSD and ntop 3.1, in fact all of the
BSD's.  I installed Linux on a box and ntop has ran fine.  However, I
have ntop (ver 3.0)  on one FreeBSD 4.9 box and it runs great for
several months now, no problems.  I think you will find ntop life much
easier on a Linux box.

Subject: [Ntop] FYI "De fault wid dis system is you,.." 3.1 on FreeBSD
4.x


Dear Ladies and Gentlemen,

I am writing to report a potentially severe problem with 3.1 on FreeBSD
4.10 (RELEASE).

Unfortunately, however, I am delighted to say that after the time it
took for me to collect the data below, the problem has ceased.

FYI, when ntop 3.1 starts with the --set-pcap-nonblocking option on
FreeBSD 4.x, as noted in the FAQ, it _eats_ CPU: on the system below,
top reports that the least share of CPU cycles consumed by ntop is 60% -
this monitoring a flow of <= 256 kbps (kilo _not_ mega).

Like 3.0, however, this usage gradually falls down to more
acceptable levels. Unlike 3.0 it takes longer to do so (prob between
10-15 minutes).

Please accept my gratitude to the developers of Ntop for sharing their
labour, and my best wishes for them and their families at Christmas.

I can't wait to see the new look and feel ...

Yours sincerely.

   NOTE: The --w3c flag makes the generated html MORE compatible with
the
               w3c recommendations, but it in no way addresses all of
the
         compatibility and markup issues. We would like to make ntop
more
        compatible, but some basic issues of looking decent on
real-world
      browsers mean it will never be 100%. If you find any issues,
please
                                                report them to ntop-dev.
