This probably depends on distro. (You're not running bind under MS
Windows are you?? :-).
Generally, services like bind, sshd and such should be managed with their
runlevel control scripts rather than just killing PIDs. Have a look in
/etc/rc.d/init.d/ for the scripts that control services. Then either run
them directly (usually if you run one of these with no args you'll get a
useage message) with a 'status' argument to see the status of the service
and with a 'stop' argument to halt them. Eg. to stop your ssh daemon, run
or, under RH (which I use), do
service sshd stop
for the same effect.
To control whether they start at all, look at the symlinks in the
/etc/rc.d/rc<n>.d/ directories where <n> is a number between 1 and 5
(between 0 and 6 actually but 0 and 6 are system halt and reboot so these
should only hold 'kill' symlinks). You'll see two sets of symlinks, all
of which link to the scripts in the init.d directory. One set of links
beginning 'K<nn>' are 'kill' symlinks and <nn> is a number that specifies
the order in which they are run. The other set, beginning 'S<nn>' are
When you change runlevel, the 'kill' scripts in the new runlevel are run
first with 'stop' arguments. Then the 'start' scripts are run with
'start' arguments. These symlinks can be modified by hand but probably
should be managed with that distribution's 'runlevel editor' tool. I use
RH's 'chkconfig' commandline tool.
If you cite your distro, those in the know will detail the commands to
