Running ntop as daemon

Hello everyone

I just have a quick question: I'm trying to monitor my net usage on a
single local machine, and at the moment my primary interface is a USB
ppp modem, so I normally don't bring the interface up until after I've
logged in.

If I include ntop in my system daemon list (I'm running Arch Linux),
what is its expected behaviour if an interface is unavailable? Will it
exit or crash, or wait for the interface to become available?

Also, can I monitor multiple interfaces at once, for example, ppp0 and
wlan0?

Robbie

U can monitor multiple interfaces concurrently. I think ntop will skip an interface that's not up, but not sure. Try it?

Re: Running ntop as daemon [In reply to]

That's dependent on whether the OS presents it to the program in the scan...
since it's USB and thus dynamic, almost certainly it will not be seen by
nTop. nTop does not go back and re-scan at anytime (unless the source has
significantly changed in that area in the last 5 years).

So add a dependency to your startup scripts to bring the network up first,
then nTop. That's always a good idea - if you start nTop before the network
is up there's nothing to see here.
