Possible errors in the latest release.

When a monitored interface goes down, i.e a virtual interface, ntop behaves unpredictable, not showing any graphs or becomes un-responsive or refuses to start/restart.

If a monitored interface does not excist (or goes down), I think ntop should just skip it.
Currently having problems with ntop together with a pptp vpn tunnel, that creates a virtual interface and sometimes it goes down because of other reasons.

Also getting loads of these

how can I reproduce this? What interface type you use and where (OS)?

make sure that you have configured the rrd plugin NOT to use rrdcached

Re: Possible errors in the latest release. [In reply to]

Thanks, will do over the weekend.

For now, I�ve deleted everything in the data-dir (/var/ntop) except the
ntop�pw.db file, restarted, and it seems to work, at least for now.

My guess is that ntop screwed up something and couldn�t recover from it.

Re: Possible errors in the latest release. [In reply to]

Compiled and up and running, since half an hour or so.

One thing I�ve noticed, it only sees half of the hosts on the local network

Furthermore, my CENTOS 5.3(5) router/GW is identified as Win95

My CENTOS 5.3 server is identified as linux 2.4

Re: Possible errors in the latest release. [In reply to]

Although ��db-file-path� is set in ntop.conf, it does display correctly in
the web-gui �Admin/Configure/Startup Otions� nor in
�Admin/Configure/Preferences�

I have set it in the configuration file as �/var/ntop� but in the gui its
�/usr/local/var/ntop/

However, in �About/Show Configuration� it is correct.

Same applies to other settings in the ntop.conf

Re: Possible errors in the latest release. [In reply to]

The GUI stores settings in a DB and has default values, that's what you're seeing.
