first of all your ntop fails on creating directory /var/lib/ntop/rrd so check if directory exists and you have rights to it asuser nobody (thats user ntop is starting as)

[bacil]

OK,

JUST TESTED THIS.it appears that there is bug in install and /var/lib/ntop is installed with wrong rights there are two ways around it

1. faster one

sudo chown -R nobody:nogroup /var/lib/ntop

2. slower but nicer

sudo chmod 755 /var/lib/ntop

sudo mkdir /var/lib/ntop/rrd

sudo chown -R nobody:nogroup /var/lib/ntop/rrd

and then you can run


sudo ntop &

and connect to it on http://localhost:3000
