The probe must be started manually with the "-noip" parameter if the NIC doesn't have an IP assigned to it:
java -jar Probe.jar -noip Probe startup initialized... loading protocol definitions... Enter name of network device to open (i.e. eth0): eth1 Probe is running Please open http://linux:7030/ in your web browser.
On *NIX, you can use the device name as parameter to "-noip", to avoid interaction:
java -jar Probe.jar -noip eth0 Probe startup initialized... loading protocol definitions... Probe is running Please open http://linux:7030/ in your web browser.
