The answer to your questions depends on the dameon you wish to
restart. However, generally speaking, you can use kill -HUP <pid> to
restart/reinitialize a daemon. To use portmap as an example, try using the
command 'ps waux | grep portmap'. You should get back a line that looks like:
daemon 420 0.0 0.2 832 412 ?? Is 12:28AM 0:00.00
/usr/sbin/portmap, which gives the pid of 420.
You can kill the portmapper with kill -9 420. To restart portmap, issue the
command /usr/sbin/portmap. If you want to restart/reinit, do kill -HUP
420. This allows you to work with portmapper while the server remains up. Of
course, if someone is using a service that depends on the mapper, then you
may crash them if you restart the service. NFS comes to mind.
