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

interface = napa0

# filter option must be commented out !!! E.g.
#filter = udp or (vlan and udp)

/opt/napatech3/config/ntpcap.ini

# Napatech default ntpcap.ini file
[Common]
Ntpl1 = "Assign[streamid=0;txport=0;txignore=true]=all"

[napa0 ]
StreamId = 0
Tx = 0

old version

[napa0]
Rx1="Assign[streamid=252;txport=0;txignore=true]=all"
Tx=0

/opt/napatech3/config/ntservice.ini

[System]
TimestampFormat = NATIVE_UNIX
TimestampMethod = EOF 
HostBufferWaitMethod = 0 
SDRAMFillLevelWarning = 0

[logging]
LogMask = 0x07
LogToFile = 0
LogFileName = /tmp/Log3G_%s.log
LogBufferWrap = wrap

[Adapter0]
AdapterType = NT4E
BusId = 00:07:00:00
PacketDescriptor = NT
HostBuffersRx = [8,16,0]
HostBuffersTx = [8,16,0]
TimeSyncProtocol = NT
TimeSyncConnectorIn = Ext
TimeSyncConnectorOut = None
TimeSyncConnectorRepeat = None
TimeSyncTimeJumpThreshold = 1
TimeSyncTimeOffset = 0
MaxFrameSize = 9018
AltTPID = 0x8100
Profile = Capture
DiscardSize = 16
OsTimeSyncFailover = DISABLE

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
