Is another instance of ntop running? Fri May 21 11:15:30 2004 2. Make sure that the use you specified can write in the target directory If I chown nobody:nobody /var/lib/ntop/, ntop appears to start. Howver, I don't know if that is the best way to fix the problem. Perhaps a new ntop user/group?
Same thing for ntop-2.2c, after "chown -R nobody:nobody ntop/" also rrdtool works now.
fixed in portage
