Open a terminal window and change to the directory where you downloaded netprobe-xxx.tar.gz. Unpack the file by typing "gzip -cd netprobe-xxx.tar.gz |tar xvf -".
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 include a trailing "/".
To start the probe, type "./netprobe start". You need to be logged in as root to run Network Probe. The 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 config folder in your old Network Probe directory to the config folder in the new Network Probe directory. Any logged data data from version 2.x can also been copied from the old statistics folder into the new statistics folder.
