Hello
I was using the previous version of ntop without any problems, but it
started to report me database corruption even when ntop is the only one who
read and update these databases.
Ntop was running perfectly in debian sarge (stable version) together with
another tools.
Asking for the solution to my problem somebody adviced me to download the
last version of ntop from the cvs servers.
for this new version I had to install rrdtools from the source code, and I
took care of all necessary dependencies, but installing the new version
together with the rest of tools I have in my debian I faced
problems,clicking over the images for 'Active End Nodes' did not show me any
graphs.
I tried to solve the problem in different ways but still today I don't have
the answer for this issue.
I installed a fresh version of debian sarge with only ntop, according to the
same procedure I used, everything was visible, but still, I can not have a
whole computer only for ntop.
I installed a fresh debian with xen to use virtualization, in this way ntop
could have a virtual machine only for it.
but after configure everything and try install ntop in the same way I did
with a fresh debian I have another problem.
-In the main page, in the section related to 'Network Load' now appears
like another ntop's page and inside I can read
*************************
Error 404
The server cannot find the requested page (page expired or ntop
configuration ?).
Received request:
"GET /graph_if.svg HTTP/1.1"
Warning
ntop does not currently have any information about host graph:i [ Whois ] .
This is most likely because the host information has been purged as
inactive. You may wish to consider the -c | --sticky-hosts option, although
that option may substantially increase memory requirements.

I tried to use -c and --sticky-hosts option at the moment to call ntop but
nothing happened
Moreover here are the logs after install ntop on the virtual machine, as you
can see other warning is reported

*************************
I don't like to use virtualization because it generates for me another
problems.
In case I have to monitor multiple network segments, I need to use multiple
network cards, I still have to find the way how can I do it with xen because
for the virtual machine with ntop will be necessary to configure multiple ip
addresses associated 1-1 to the real network interfaces I might have.
If I could find the way to put ntop in the same scenario as it was before
with the previous version, it will be great for me, in this case I can avoid
the use of xen who generated additional overload on the server.
I'd like to know if it's a mistake in mi procedure of installation, or if
are necessary antoher checks to figure out why ntop doesn't execute properly
on the previous scenario
it's a collection of efforts to install ntop properly.
Thanks in advance for any help
