Try it without -S

That's been removed (we now use rrd for persistent data) and there are a
number of reports of problems with it.

Otherwise, run ntop under gdb -- instructions in the docs/FAQ or at
http://snapshot.ntop.org and capture the failure information.

Subject: [Ntop] ntop crashes because of forwarding ports


Hello,

I have installed ntop 2.1.3 on a RH 6.2 box. Compiled it myself before.
The box acts also as a router. The machine does also ip forwarding.
I.e., port 80 is forwarded to another machine in the local LAN. Ntop
starts fine from the init.d-script with the following command line:

$prog -d -P /usr/share/ntop/ -E -L -u ntop -w 3000 -S 2 -i eth1

The problem is that, when I connect from the internet to port 80 on the
machine where ntop is installed (port 80 is forw. to another machine, as
I wrote), ntop "crashes" which means that I read in the "messages" log
that eth1 has left promiscuous mode, so ntop has stopped. Is this a
"normal" behaviour, which means that one cannot install ntop on a box
which does also ip forwarding? Do I have to give ntop more parameters?

Thanks for help,

Stephan
