Hi,
And how do I compile with debug?
Replace -O2 with -g into the Makefile file
Also I noticed some changes in libpcap drop rate after upgrading with
"apt-get upgrade"
Also, changin Sample Rate.
If I set it to 2 or more, libpcap drop rate is 0%
If I set it to 0 or 1, libpcap drop rate is, in 10min work time, ~15% and
growing over time.
How big do you need the pcap file for analyzing it? 1 hour, 1 day....?
large enough to reproduce the problem

Thanks
Daniel
SVN please

Daniel,
please compile ntop with debug information so that we can analyse the
core
As of dot, it might be your map is too big.
If you want us to improve our DPI library so that we reduce the Unknown
traffic, I need you to send me a pcap file with full packets I can use
to check what's going on.
Thanks Luca

Hello again,
Also to mention. After a few hours working NTop crashes with this:
Oct 12 18:43:11 netanalyzer kernel: [173411.012267] ntop[16461]:
segfault at 35382e37 ip 00007f4db7433dba sp 00007f4da8a852c0 error 4 in
libc-2.15.so[7f4db73ea000+1b3000]
Anything?

Hello everybody,
Im testing last NTop stable 5.0.2 with PF_RING from the ubuntu x64
packages in a Ubuntu 12.04 TLS 64bit version.
The box is a Dual Xeon 2.8GHz (2 physical cores) with 2Gb RAM with a
RAID 1 SCSI 10k rpm 40Gb hard drive.
I have NTop in a mirroed switch port monitoring a 100Mb/s average
network. Peak is about 200Mb/s
Im having some issues with libpcap packet dropping and also with nDPI.
In less of an hour running ntop, I have:
Dropped (libpcap) 44.8% 16,262,915
Dropped (ntop) 0.0% 0
Total Received (ntop) 36,289,290
Total Packets Processed 36,289,291
WIth pfcount -i eth1 there is no packet drop.
And in the Application Protocol TAB arround 40~50% of traffic is
unknow while http and bittorrent are really low. HTTP have an average
of 30Mb/s and Bittorrent have 3Mb/s average. And Im very sure there
are more of those.
I tried opendpi_netfilter before (nDPI based sources) and bittorrent
was arround 40MBit and http arround 60Mbit
Also some things dont work for me. Like:
IP -> Local -> Network Traffic Map | this keep loading while dot is
consuming 100% CPU
In the Interface Report TAB, Remote Host Distance graph draw a very
big legend that goes from upper graph to bottom graph.
Im doing something wrong?
Thanks in advance.
PS: Sorry for my english
