New Package: ntopng

Cino

Pull request has been accepted and merged. You should see an update for ntopng in Package Manager

Mr. Jingles

I uninstalled it to see if this package perhaps made my box crash. After that, my log is flooded with this:

ntopng: [PeriodicActivities.cpp:83] ERROR: Missing script /usr/local/share/ntopng/scripts/callbacks/second.lua

Literally thousands of these lines, 1 per second it seems.

But it isn't installed anymore ;D

How might I perhaps fix this?

Thank you :)

The process must not have stopped. Try

killall -9 ntopng

Mr. Jingles

Worked marvelously, Jim: thank you ;D

Hello,
i can't use the historical feature. when i try to load historical data after setting interface and time interval i see this error message on the log

ntopng: [Lua.cpp:72] ERROR: ntop_find_interface : expected string, got number

i'm using 2.2-RC x64 release with Intel interfaces.
Has anyone tried this feature?

What interface is it best to listen on, just LAN interfaces or LAN + WAN?

Cino

@raab:

What interface is it best to listen on, just LAN interfaces or LAN + WAN?

LAN should be good. Or you can select both

jimp

If you are interested in identifying which local user is sending out specific traffic, then listening on LAN is best. LAN+WAN may catch some additional traffic that originates to/from the firewall that doesn't hit LAN.

If you are routing traffic (no NAT) then WAN alone works, too.

Wondering if anyone is experiencing readability issue for ntop? I am running it on pfsense 2.2 and seeing garbled texts on the RRD graphs.

Cino

@packeteer I haven't… Maybe stop it and wipe the DB? /var/db/ntopng and start fresh?

I have to say going from 2.1.5 to 2.2, what a difference with ntopng... I thought sqlite wasn't compile in 2.1.5 because I didn't see any historical data. With 2.2, everything is there. And I can rename interfaces and such

I've been messing with other options and thinking about adding the following options if there is a need:


--enable-aggregations (only works using -A, core dump if I use --enable-aggregations)
--dump-timeline
--dump-hosts
--dump-aggregations

https://svn.ntop.org/svn/ntop/trunk/ntopng/doc/UserGuide.pdf

Has anyone renamed an interface or stop a flow alert then stop/start ntopng or rebooted and noticed all customize you did is gone? I'll have to research but I'm wondering if it has somthing to do with redis-server

I installed ntopng in new install pfsense 2.2 with LAN,WAN (inactive),OPT1 (active), other packages: darkstat, squid3, squidguardian, sarg.
DHCP (31 static leases), DNS resolver (registering DHCP leases).
ntopng settings: capturing LAN, Decode DNS responses and resolve local numeric IPs only (default),
Turn historical data storages on ticked

to solve locating scripts problem:

ln -s /usr/pbi/ntopng-amd64/local/share/ntopng /usr/local/share/ntopng

To solve GeoIP problem: [Geolocation.cpp:59] WARNING: Unable to read GeoIP database /usr/local/share/ntopng/httpdocs/geoip/GeoLiteCityv6.dat

Downloaded geoIP in /usr/pbi/ntopng-amd64/local/share/GeoIP

cd /usr/pbi/ntopng-amd64/local/share/ntopng/httpdocs/
ln -s /usr/pbi/ntopng-amd64/local/share/GeoIP geoip

Now, my problem:
notpng show LAN hostnames based on network traffic such LAN hostnames, example:

ntopng db cleared
ntopng displays the LAN hostnames correctly
As for traffic, the LAN hostnames changed :
192.168.20.1 (LAN gateway, ntopng capture) hostname: zpf22.domain.local, ntopng show www.google.es, then clients1.google.com, then vl.ff.avast.com, etc.

You could avoid change LAN hostnames based in traffic?

Thanks in advanced, this amazing product!!

I split several unrelated issues off into separate threads, and I'm locking this one. Please start a new thread for each new issue rather than using a single thread.

Thanks!
