Napatech
Configuration & building
First Installation
The old way
- download latest Napatech drivers and untar it into e.g. /opt/napatech3
- build the driver
- download the the sniffer's source
cd /usr/src git clone https://github.com/voipmonitor/sniffer.git cd sniffer ./configure
Install all libraries that the configure needs.
- edit INCLUDES and LIBS_PATH lines in the Makefile
INCLUDES = -I/usr/napatech3/include -I/usr/local/include ${MYSQLINC} -I jitterbuffer/ ${JSONCFLAGS} ${GLIBCFLAGS} LIBS_PATH = -L/opt/napatech3/lib -L/usr/local/lib/
- run make
- check it's built properly
root@server:/usr/src/sniffer# ldd ./voipmonitor | grep pcap libpcap.so.1 => /opt/napatech3/lib/libpcap.so.1 (0x00007fc0b69b0000)
- replace original binary in the /usr/local/sbin
- run it
The new way (from the sensor's version 24.23)
- download latest Napatech drivers and untar it into e.g. /opt/napatech3
- build the driver
- download the the sniffer's source
cd /usr/src git clone https://github.com/voipmonitor/sniffer.git cd sniffer ./configure --with-dpdk-include=/opt/napatech3/include --with-dpdk-lib=/opt/napatech3/lib
Install all libraries that the configure needs.
- run make
- check it's built properly
root@server:/usr/src/sniffer# ldd ./voipmonitor | grep pcap libpcap.so.1 => /opt/napatech3/lib/libpcap.so.1 (0x00007fc0b69b0000)
- replace original binary in the /usr/local/sbin
- run it
Upgrade
The manual way
cd /usr/src/sniffer git pull make
- copy to the original directory and restart sensor
The automatic way
- set these options into voipmonitor.conf
upgrade_by_git = yes git_folder = /usr/src/sniffer configure_param --with-dpdk-include=/opt/napatech3/include --with-dpdk-lib=/opt/napatech3/lib
- restart sniffer
- do the upgrade via clicking in the GUI
The sniffer will perform (after click on UPGRADE in GUI) git pull,configure,make_clean,make, service voipmonitor stop, make install, service voipmonitor start.
Settings
- in voipmonitor.conf

Timing source In napatech where timestamp of packets is shifted to GMT and you want use system time instead: GMT:
TimeSyncConnectorExt1 = PpsIn
System dependent:
TimeSyncConnectorExt1 = NttsIn
