this script should stop the ntop and start it again after 8 seconds.

I did some tests and ntop will be stopped with:

my $stop = `/usr/local/bin/sudo /usr/local/www/cgi-bin/ntop/ntop.sh st
+op` or die "cannot stop ntop: $!";
[download]

and started again with:

<br>
my $start = `/usr/local/bin/sudo /usr/local/www/cgi-bin/ntop/ntop.sh s
+tart`
or die "cannot start ntop: $!";
[download]

I cannot see errors on the ntop output.

I have only one problem if the ntop is already running,
an I start the script, I don't get any errors,
but if it was stopped before,
then I get an error:

Software error:
cannot stop ntop:  at /usr/local/www/cgi-bin/ntop/ntop.cgi line 41.

it needs to check first if the ntop is already running and then stop it.
