#Windows walk-through

The following steps describe how to use this tool on Linux. We used Centos 7.0 (x64).

The following steps may require root privileges.

##Step 0: Get a copy

git clone https://github.com/andymalakov/libpcap-latency-meter.git

The following notes assume that you placed them into LATENCY_METER directory.

##Step 1: WINPCAP library

Download and install winpcap. We tested with version 4.1.3.

##Step 2: jNetPcap (Java wrapper for LIBPCAP)

  • Download jNetPcap. We tested with version 1.4.r1425.
  • Copy jnetpcap.dll and jnetpcap-pcap100.dll into LATENCY_METER/bin.
  • Copy jnetpcap.jar into LATENCY_METER/lib.

##Step 3: Build it ant build

##Step 4: Verify setup

Let's capture some network traffic. Build script includes 'hello' target that displays network interfaces discovered by WINPCAP and captures first few packets from interface #0.

ant hello
hello:
