Yuri, your writing give me confidence to do fresh install of both ntopng and nprobe. I followed the same steps and it worked:).
In my office machine , I was restarting/starting the ntopng from the windows service tab. This time , I started using command-line. Or what about local-fw does it have to be turned off? Does ordering matters? Thanks. On Tue, Aug 25, 2015 at 6:05 PM, asad <[email protected]> wrote: > Sorry for confusion, that the problem I'm not seeing packets displayed on > UI.
