 So im trying to configure ntop, which is currently running fine, to use another interface for monitoring. Currently its using the same interface the web pages are dilivered on.  So I goto to admin web page >> preferences and under the -i option it gives me "You cannot set the capture interface: missing privileges." fine so i need to be roo or whatever. then I click "Show configurattion" link at the bottom and get a page that gives me the parameters that ntop starts with. Under "start as" i get this line "/usr/sbin/ntop -d -L -u ntop -P /var/lib/ntop --access-log-file -i eth0 -p /etc/ntop/protocol.list -O /var/log/ntop "
awsome!!! the golden egg. I search the internet for hours trying to find where this line is kept and nothing every file it suggests is either blank or non existant. Im running Ubuntu 10 can anyone solve my mystery??!!  arg

That line nowhere to be found because it is generated by the start script for ntop: /etc/init.d/ntop
It contains the following lines:
  start-stop-daemon --start --quiet --name $NAME --exec $DAEMON -- \
  -d -L -u $USER -P $HOMEDIR \
  --access-log-file=$LOGDIR/access.log -i "$INTERFACES" \
  -p /etc/ntop/protocol.list \
  -O $LOGDIR $GETOPT

Open in new window


The bit you are interested in is  -i "$INTERFACES".
A bit of searching shows that /var/lib/ntop/init.cfg is included (via /etc/default/ntop), this init.cfg contains the following (on my box):
USER="ntop"
INTERFACES="eth0"
