Luca, ....eeeeer.....yes. I'm unexperienced using a debugger on linux.....but i'm not totally dumb, so if you could lend me a hand and tell me how to start. Ntop is installed as a package, i have not compiled it. So the first step sould be to download the source and compile it?

Can you please investigate with a debugger and report to me? Thanks, Luca Thorsten Volkmer-Wolf wrote: > Hello community, > > It's been a while since i've been here.....so: 'hello again'.
