The ntop init script uses a pidfile in the call to start-stop-daemon, but ntop doesn't create any pidfile. Thus, it looks like ntop gets stopped, but it is still running. Additionally, --retry 5 is not enough as ntop may take long time to shut down. I recomend --retry 30. Reproducible: Always Steps to Reproduce: 1. /etc/init.d/ntop start 2. /etc/init.d/ntop stop 3. ps |grep ntop Actual Results: Ntop should is still running. Expected Results: Ntop should not be running.

Ntop creates a pid file, oddly enough, to /var/lib/ntop/ntop.pid. I could not reproduce this: the init scripts works perfectly fine here. Can you give us more information?
In my experience, the created pidfile is /var/run/ntop.pid. Running "start-stop-daemon --stop --retry 30 --pidfile /var/run/ntop.pid" works for me.
Just to add that I just emerged ntop-3.2-r3 here and see the same behaviour. "start-stop-daemon --stop --retry 5 --signal 9 " in the /etc/init.d stop section appears to work here. $ sudo cat /var/lib/ntop/ntop.pid 18775 $ ps -e | grep 18775 18775 ? 00:00:00 ntop
Here too the pid file is /var/run/ntop.pid and --retry 30 actually works better than --retry 5.

Same problem here. Changing the path to /var/run/ntop.pid and setting the timeout to 30 seconds works. I had another issue, where ntop didn't work correctly. It did start, but much of the functionality didn't work at all. Setting LC_ALL=C before launching ntop fixed the problem. The same seems to have happened in Fedora, although their solution of only setting LANG=C didn't work for me: https://bugzilla.redhat.com/show_bug.cgi?id=219025#c113 The following patch solved all problems for me: --- /usr/portage/net-analyzer/ntop/files/ntop-initd 2007-07-24 23:13:25.000000000 +0200 +++ ntop 2008-03-01 19:25:10.000000000 +0100 @@ -17,12 +17,13 @@ start() { checkconfig || return 1 ebegin "Starting ntop" + export LC_ALL=C start-stop-daemon --start --exec /usr/bin/ntop -- -d -L ${NTOP_OPTS} eend $? } stop() { ebegin "Stopping ntop" - start-stop-daemon --stop --retry 5 --pidfile /var/lib/ntop/ntop.pid + start-stop-daemon --stop --retry 30 --pidfile /var/run/ntop.pid eend $? }
Any possibility of getting the fix to /etc/init.d/ntop added to an ebuild and cvs soon?

I've became the maintainer of ntop. Reassigned its bugs to me.
Fixed in cvs.
