I don't know if we've tried x86 - certainly I haven't - anyone want to
donate 2K worth of hardware? There could be 32 bit assumptions buried in
the code. You need to run under gdb to capture the failure point
information. Or compile as a 32 bit executable.

Subject: [Ntop-dev] buffer overflow on FC4
Hi,
I installed the RPM ntop-3.1-1.2.fc4.rf and get the result below. My system
is a 2.6.12-1.1398_FC4smp running on a dual XEON x86_64. This is a INTEL
server with the e1000 module on eth0.
My ntop.conf is pretty standard, I only disabled the HTTPS server since I
wanted to proxy NTOP through apache on a different box.
I use libpcap-0.8.3-13.FC4 .
Any ideas?
Regards
--Marcel
