RE: Segmentation fault [In reply to]

See howto ask for help at http://snapshot.ntop.org for the information we
need to look at your problem. Off hand, if it's a version prior to 2.1.2,
grab the source and upgrade.

Hi all.
I'm using ntop in a FreeBSD 4.6-RELEASE machine because I have to monitor
a 12M bytes trafic LAN. But I can't run the proces because the program
crash with the message "Segmentation Fault".

RE: Segmentation Fault [In reply to]

Thanks for the quick reply Burton. Is there a search feature for the
archives ? I didn't see one and was
having difficulty tracing the thread through the text file. Assuming I
saw everything, the answer is to get
the patch and this will fix the seg fault ? Is there anyway to get the
patch without CVS ?

RE: Segmentation Fault [In reply to]

Ok, never mind on getting the code I was able to access a server with
CVS and followed the instructions:
$ cvs checkout -r ntop_2_2_patches .

This looks like the complete build however, do I completely rebuild Ntop
or is there a way to apply the changes ?
I don't see anything with patches in its name. This is assuming the
patches are what I need to fix my problem.
Let me know if I'm on the right track.

RE: Segmentation fault [In reply to]

Very first, update your NTOP version. V2.0 is a bit long in the tooth,
as NTOP is now as 3.1, which seems to be very stable and full of
features.

Second, I would recommend getting an updated box (both h/x and os). For
a busy network, NTOP needs ram, a lot of it too.

RE: Segmentation fault [In reply to]

More than long in the tooth, totally unsupported (and, I might add for VERY,
VERY good reasons - ONE of which is the dozens of hash table resize problems
in the 2.x versions - there are lots of other reasons).

3.1 is the ONLY supported version. RPMs and source are available at
SourceForge. I'm pretty sure somebody has a deb package, but it's no big
issue to build from the source - see docs/BUILD-NTOP.txt

Re: Segmentation fault [In reply to]

OK - thanks for all your input. I was running the older 2.x version
because that was the version that was packaged for Debian and that
apt-get install grabbed.

Does anyone *own* or otherwise maintain the packages for Debian?

Anywho, I grabbed the newest from CVS and after recompiling some older
libs and adding a few more I was able to compile and run ntop v.3.1.1
MT.

I am a happy camper.

Cheers,
jeff

RE: segmentation fault [In reply to]

I found it was a dodgy version of libpcap on my linux box that kept
doing that.

I luckily had the option of rebuilding the entire machine, but im sure
it was libpcap..

Subject: [Ntop] segmentation fault

Folks -

I'm having segmentation faults and crashes on a newly built server. My
goal is to simply capture traffic on a Netgear switch with a port in
monitor mode.

The line I get in the window when ntop dies is:

Segmentation fault ntop -P /usr/local/share/ntop -u ntop -L

my environment:

RedHat FC5
ntop 3.3.3
Dell D600 with 512 MB RAM
Startup line: ntop -P /usr/local/share/ntop -u ntop -L

Does anyone have any ideas as to the cause?

thanks!

Re: Segmentation Fault [In reply to]

Please help me to understand.

ntop crashes after a couple of hour. I can't use it.

Any suggestion please ?
