ManageEngine NetFlow Plug-in for Linux non started

I have install the NetFlow plug-in downloaded from your site ( http://www.manageengine.com/network-monitoring/29809517/ManageEngine_OpManager_NetFlow_Plug-In_9000.bin), next, I run linkAsService.sh, but the plug-in doesn't start. My distro is the last Debian (6.0.3). Opmanager on this server works normally.

Whats wrong?
