if you plain to use nagios with ssh, first install openssh and make 
connections with hosts to get their keys then connect on the server 
supporting nagios as nagios user
#su nagios
generate a couple of keys
#ssh-keygen -t rsa
find the key id_rsa.pub and rename it in authorized_keys and put this 
key on the host you want to monitorize in a nagios' folder (ie 
/home/nagios/.ssh permissions have to be set to 700) and casually you 
can chown to nagios the directories.
then for the event-handler you'll connect through sudo like this
/usr/bin/ssh nagios at hostname 'sudo  /etc/init.d/http restart'
of course this have to be in a script that will start according to some 
parameters.
