why does no one answer ? :-((

Matthias,
I have committed a patch this week that double checks some activities with the virtual hosts handling. I am sure that this patch isn't enough but as I cannot reproduce the problem here I have to wait until somebody provides me a way to do that.

In addition please remember that:
1. ntop is a project carried on a voluntary basis
2. we are not forced to answer to all mails (I wish I had time for that) as we release the software according to the GPL licence (i.e. no guarantee)
3. we are free to assign priorities to our development activities (I'm busy with RRD now right now)
4. we provide (see http://www.ntopsupport.com and http://shop.nop.org) commercial support for companies like yours. Feel free to take advantage of it.

Regards, Luca

hi,

my ntop -V stats:

ntop v.2.1.3 MT [i686-suse-linux] (10/14/02 03:33:02 PM build)

on a suse linux 8, uname -a stats:

Linux fw 2.4.18-4GB #1 Wed Mar 27 13:57:05 UTC 2002 i686 unknown

ntop is build manualy from the sources.

ntop is started like this:

/usr/local/bin/ntop -u nobody -w 3000 -P /usr/lib/ntop
- -p /usr/lib/ntop/protocol.list -i eth0,eth1 -M -S1 -m 10.10.0.0/16

the problem:

on this system ntop crashes after a random period of time without any
messsage. additionaly i can crash ntop by clicking "stats" ->
"networkload" and then on one of the graphs.

any suggestion ??

TIA
