NTOPNG – NTOPCONTRIBUTOR LICENSE AGREEMENTBLOGNBOX NETFLOW/IPFIXTHE NTOP TEAMNTOPNG EDGE ntopng is the next generation version of the original ntop, a network traffic probe that monitors network usage. ntopng is based on libpcap/PF_RING and it has been written in a portable way in order to virtually run on every Unix platform, MacOS and on Windows as well.. ntopng – yes, it’s all lowercase – provides a intuitive, encrypted web user interface for the exploration of realtimeNTOP - PACKAGES

APPLICATIONS AND CATEGORIES Custom Categories¶. As shown above, ntopng already assigns a default category to the known L7 protocols. Nevertheless, it’s also possible for the user to specify a list of additional hosts to be included into a particular category. ntopng provides 5 empty “custom categories” dedicated to this task, but users are also free to modify the othercategories.
USING NTOPNG WITH NPROBE Using Behind a Firewall¶. In the remainder of this section it is shown how to connect nProbe and ntopng in presence of a NAT or firewalls. Indeed, the examples given above might not have worked well in case there was a firewall or a NAT between nProbe and ntopng. PFSENSE — NTOPNG 4.3 DOCUMENTATION Note. If you already have ntopng community build installed from the builtin repository, please remove it and also delete the data directory under /var/db/ntopng COMMAND LINE OPTIONS Ntopng uses Redis as a backend database to store user configuration and preferences. Redis must be started before ntopng. By default the location is localhost but this can be changed by specifying host and port where Redis is listening.
