deb files and install them manually (follow the right steps because there are some dependencies): wget Well, the other way to get these packages installed would be downloading the.
Ntopng not showing new interface update#
The easiest way to get these packages installed would be installing their sources in APT : wget Īnd do an update of package list : apt-get clean all But I’m pretty sure it works with 14.04, maybe I’ll test it and update this post according to it.
I used Ubuntu 12.04 amd64 with latest updates for this setup.
Ntopng not showing new interface license#
Sadly, this one is not free, and you will need a license to get it working in production environnement as the default-installation provides a 20K flows limit per nprobe thread, then it stops collecting them. That means that if you have a couple network devices on a network, and you want to know what kind of flows are going through your network, you will have to install a separate tool, which is also developped by the ntopng guys : nProbe. It cannot work as a netflow collector too. Just to clarify things before we put our hands in the dirt, ntopng is a netflow analyzer with a nice web-interface, that can get the traffic of its own interface. Well, as I will have to install the whole setup myself again, I prefer write it here and share it with you. It may be necessary to schedule a cron job to clear out the cache periodically and restart ntop after deleting the older folders.Maybe you thought the same as I thought when I searched online for good ntopng tutorials : “damn, I’ll have to make my own”. If you have a high-volume router that you are monitoring, you may end up hitting a folder limit for your rrd interfaces directory(max of 32 000) depending on how you have flows being processed/parsed.If there isn't data present, make sure firewall on both router and ntop host have port 2055 (and possibly 2056) open from the router to the ntop host.Finally, softlink /usr/sbin/e to /usr/sbin/fprobe. Copy /etc/conf.d/fprobe to /etc/conf.d/e and change interface line to IP on gre interface and port line to 2056. To monitor 2 interfaces (gre1 given as example), copy /etc/init.d/fprobe to /etc/init.d/e1, edit BIN= line to point to /usr/sbin/e.If receive error regarding font not found you can add ttf fonts: In case have trouble creating password, you can delete previous databases and recreate again:
