NTOPNG CERTIFICATE INSTALL
Upon doing so, the application will retain any supplementary group memberships that the initial user has (in the typical case, this is the root user) – and if the root user is not member of the napatech group, then after dropping privileges, the application is not allowed to access the Napatech SmartNIC device, since when ‘napatech’ group is present, the Napatech 3GD driver will use this group to control which users can access the SmartNIC. 1 To create the self-signed certificate you need to: 1.1 Install OpenSSL On Debian/Ubuntu: sudo apt-get install openssl OnRedHat/CentOS: sudo yum install openssl On OSX do: brew install openssl 1.2 Create your SSL certificate inside the ntopng folder execute the command: make cert and follow the instruction 1. The reason for the problem is that the ntopng application attempts to drop user privileges to another user, by default this is the ‘nobody’ user. is TCP SSL Certificate Throughput Flow traffic dump to persistent storage. Ntopng web interface is accessible: from specified TCP port (default is 3000 with access only from green interfaces) from Server Manager using a proxypass. The ‘root’ user is not member of the ‘napatech’ group.The ‘napatech’ system group is present in the system.pcap-napatech-3g.c 1417: napatech_pcap_read_segment: NetRxOpen failed ((NTE_MODULE_NTIPC_CON):IPC connect socket failed)
# LD_PRELOAD=/opt/napatech3/lib/libpcap.so. The ntopng application can interface to the Napatech SmartNIC via the libpcap interface.ĭepending on how the Napatech 3GD driver has been setup/installed, the user may face a "NetRxOpen failed" error upon starting ntopng:.
