New Package: ntopng

yefryf

Recently I've installed ntopng in my pfsense firewalls and It's really a good tool, thank for the package.

I am reading and investigation to learn more about this tool and I would like to know if it is possible to upgrade the ntopng's version to 1.2. By the way, when I access to the dashboard it showing the attached message.

@jimp thanks again for taking the time to create this package…

couple of things,

1 Should we have to worry about this error in the system log?


ntopng: [Prefs.cpp:408] ERROR: Unable to create log C:\Windows\Temp/ntopng.log

2 I should read the manaul but there isn't much under the admin menu as far as configuration. I was hoping to re-name the interfaces to laymen names.

2.1.4-RELEASE (i386)
built on Fri Jun 20 12:59:29 EDT 2014
FreeBSD 8.3-RELEASE-p16

@jimp:

We can't take direct donations anymore. It's not quite enough for a Gold subscription or I'd say just get one of those. But you can pick up some stuff from the pfSense store with that and you'll get some swag out of it on top of us getting a cut. :-)

Could I ask, Jim: why can't people donate anymore? I know I did last year, and suddenly it was gone. I bought a Gold to support (and buy you all a beer ;D ) but I kept on wondering: why did you remove the donations? It is people wanting to show their appreciation, and some money seems better than no money (but then again, this is the stupid economist speaking here: if there is anything we don't understand, it is money ;D ;D ;D ).

Eeehm, sorry for the mildly intelligent question, but: on my nano 2.1.4 boxes there is no ntop or ntopng package available in the list… What's wrong here? :o

Not until 1.2 shows up in FreeBSD ports. I'm told it's being worked on.

I don't think it's worth worrying about

I don't know the nitty gritty details, but since we're not a non-profit organization, taking donations in that way has some weird tax/legal issues. The beancounters said it caused more trouble than it was worth.

ntop isn't compatible with NanoBSD installs, only full installs.

Too bad!!

btw: If I had the choice between paying an invoice (including VAT) and giving a donation, I knew which option I would choose… :-D

Right :P

Well it so happens I am a post-academic bean counter ( ;D ), and the thing is:
1. I don't know the specifics of US GAAP (Generally Accepted Accounting Principles), theree might be a twist in there, but:
2. (Donation/1+ VAT-percentage) (so: 50/1,06 assuming VAT 6%) should do it, at least under IFRS (International Financial Reporting Standards).

Of course, neglecting the 'twist' mentioned before.

But, to my knowledge, there is no country in the world that forbids companies receiving money that can be taxed both VAT and profit tax.

The offset is the paypal fee. Which I believe is 3-5%.

Which I would assume would make it worthwile: 50 dollars from me, minnus the VAT, minus the corporate tax, still leaves nett money even when offset against the paypal fee.

Sincerely,

Sr. Beancounter ;D

Hi,

For the record, I think I found out what the problem was with my pfSense installation and this package. I did a bit of digging and found that there had been a previous installation of NRPE on this firewall which had somehow or another failed or been aborted, which must have corrupted the config. When I examined the /cf/conf/config.xml file, I discovered that this installation was still showing in the the 'installedpackages' section. The description for NtopNG was below, but the xml for the associated menu items was completely missing. Editing the config.xml, inserting the relevant xml for Ntop, resolved the problem completely.

Thanks for a very useful contribution to the pfSense community!

Is it possible to have this program display the bandwidth used per time period?

@scotty562:

It's possible to get historical views for individual hosts for a predefined date/time range. You'll have to enable historical data storage:

1. open a terminal and log in with root account
2. open the launch script with an editor:


vi /usr/local/etc/rc.d/ntopng.sh

3. add "-F" to the last command in the "rc_start()" block, so it should look like this:


rc_start() {
        ldconfig -m /usr/pbi/ntopng-amd64/lib
        /usr/pbi/ntopng-amd64/local/bin/redis-server --dir /var/db/ntopng/ --dbfilename ntopng.rdb &
        /usr/local/bin/ntopng -s -e -F --dns-mode '0'  --local-networks '192.168.0.0/16,172.16.0.0/12,10.0.0.0/8' &
}

4. stop and start ntopng:


/usr/bin/killall ntopng
/usr/local/bin/ntopng -s -e -F --dns-mode '0' --local-networks '192.168.0.0/16,172.16.0.0/12,10.0.0.0/8' &

I haven't been able to get the aggregate on an interface - is that available somewhere? edit: The total data throughput is available at 'Overview'.

You could edit '/usr/local/pkg/ntopng.xml' so you dont have to edit /usr/local/etc/rc.d/ntopng.sh when you reboot or resave ntopng options in the gui

Mr. Jingles

That is ONE sexy package :P :P :P

(I don't really know what I am looking at, but I am like that bird that likes anything that blinks (Dutch: ekster): this is some interesting 'bling-bling' to study ;D

(On another note: how comes no site shows up normally in IE, you would have expected MS to understand something now after 35 years and an army of 150.000 employees. Firefox is getting more bloated by the second (2 gigs of RAM currently, for-a-browser?), Chrome is NSA, and Opera apprently has decided to come a 'living dead').

Adding a new checkbox option to enable that should be simple. I don't have time at the moment but I'll keep it in mind next time I poke at the package.

Or someone could add it and submit a pull request.

funny you brought this up… i'm already on it :-) might be ugly since i'm not a programmer but sure can copy and paste... hehehehe

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?
