Introduction Network Probe is a network traffic monitor and protocol analyzer that gives you an instant picture of the traffic situation on your network. It displays detailed information about the type and amount of network traffic, and helps you identify potential problems and bottlenecks in your computer networks. http://www.objectplanet.com/probe 1 Chapter 2. Installation Windows installation Double click the Network_Probe_2.x-install.exe file and follow the instructions. During the installation, a packet driver will be installed as well. A restart of the computer is required after installation is done, otherwise the packet driver won't start. The 2.x version will not overwrite any existing 1.x versions. If you have a 1.x version installed, you can copy the file "Program Files/Network Probe/config/config.txt" to "Program Files/Network Probe 2/config/config.txt", to keep old configura- tions. Any logged data from the 2.x version can also be copied from "Program Files/Network Probe/ statistics" to "Program Files/Network Probe 2/statistics". The first time Network Probe is started, you are prompted to set a password for the "admin" user. http://www.objectplanet.com/probe 2 Linux installation 1. Open a terminal window and change to the directory where you downloaded netprobe-xxx.tar.gz. Un- pack the file by typing "gzip -cd netprobe-xxx.tar.gz |tar xvf -". 2. Change to the newly created netprobe directory and open the "netprobe" file in a text editor. Locate the line starting with JAVA_PATH= and insert the full path to your Java binary directory. Do not in- clude a trailing "/". 3. To start the probe, type "./netprobe start". You need to be logged in as root to run Network Probe. The http://www.objectplanet.com/probe 3 first time you start Network Probe, you will be asked to set a password for the admin user. Startup parameters can be set in the line starting with STARTUP_PARAMETERS=, located in the file "netprobe". To keep configurations from older versions of Network Probe, copy the file "config.txt" from the con- fig folder in your old Network Probe directory to the config folder in the new Network Probe direct- ory. Any logged data data from version 2.x can also been copied from the old statistics folder into the new statistics folder. Mac installation 1. Unpack the downloaded netprobe-xxx.tar file by double clicking it. 2. Open the newly created netprobe directory and open the "netprobe" file in a text editor. Locate the line starting with JAVA_PATH= and insert the full path to your Java binary directory. Do not include a trailing "/". 3. To start the probe open a terminal and change to the newly created netprobe directory. Type "./netprobe start". You need to be logged in as root to run Network Probe. The first time you start Net- work Probe, you will be asked to set a password for the admin user. Startup parameters can be set in the line starting with STARTUP_PARAMETERS=, located in the file "netprobe". To keep configurations from older versions of Network Probe, copy the file "config.txt" from the con- http://www.objectplanet.com/probe 4 fig folder in your old Network Probe directory to the config folder in the new Network Probe direct- ory. Any logged data data from version 2.x can also been copied from the old statistics folder into the new statistics folder. License key To enter the license key click on "Setup" and then on "Probe configuration". Enter the license key in the input field and click the "Update" button. Deployment The Home Edition (free) of Network Probe supports single-computer mode only, so only traffic going from/to the computer where Network Probe is installed will be picked up. It can be connected to a nor- mal port on the switch. For full utilization of Network Probe, a license key is required, which will enable promiscuous mode. Promiscuous mode means that it can pick up all network packets which the network card sees. Make sure you install the probe on a computer with a network card capable of promiscuous-mode operation. If the card does not support promiscuous mode, a warning is shown on the login screen (also in Home Edition): http://www.objectplanet.com/probe 5 The computer should be connected to a mirrored port on your network switch, also known as a SPAN (Switched Port Analyzer) port. The normal operation of a switch is to send packets only to the computer they destinate to, but a SPAN port receives a copy of all packets going through the switch. A SPAN port is normally available on managed switches only. It is also possible to use Network Probe on a wireless network, as long as the wireless NIC supports promiscuous mode. After installation, you can log on to the probe using any web browser from any computer having access to port 7030 on the computer where Network Probe is installed. Strategically install a copy of Network Probe on each subnet you want to monitor, and log in remotely from a single central location. http://www.objectplanet.com/probe 6 System requirements • Windows XP, Windows Vista, Windows 2000, Windows 2003, Linux, FreeBSD, MacOS X, Solaris (with root access) • Sun Java Runtime Environment 1.3 or higher.
