* note
i'm hardcoding the libs for nrpe because
configure does this...
checking for type of socket size... size_t
checking for SSL headers... SSL headers found in /usr
checking for SSL libraries... configure: error: Cannot find ssl libraries
meh
# apt-get install libssl-dev
# ldconfing
# apt-file search libssl | grep libssl-dev
...
set up the nrpe daemon
# echo 'nrpe 5666/tcp # NRPE' >> /etc/services
# cp /usr/local/src/nrpe-2.15/init-script.debian /etc/init.d/nrpe
# chmod +x /etc/init.d/nrpe
# sysv-rc-conf
set to runlevels 2 3 4 5
q to exit :^)
edit nrpe.cfg to site specs
# vi /usr/local/nagios/etc/nrpe.cfg
run nrpe daemon
# /etc/init.d/nrpe start
running?
# netstat -an |grep 5666

check if npre is accessible. the rev show show up.

common prereqs:
libssl-dev
apt-file
sysv-rc-conf
note:
if you see the make error in npre section (make will not tell you, you have to watch the process):
./nrpe.c:269: undefined reference to `get_dh512'
a hint is when you rn /etc/init.d/nrpe and do not see the output:
Starting nagios remote plugin daemon: nrpe.
edit dh.h with C-code output if openssl is installed.
# openssl dhcparam -C 512 > /usr/local/src/nrpe-2.15/include/dh.h
and removing all between:
-----BEGIN DH PARAMETERS-----
-----END DH PARAMETERS-----
if running openssl comes up as not found,
apt-get install openssl
for ubuntu 10 and lower:
--with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib
if you do not want to roll your own:
apt-get install nagios-nrpe-server
apt-get install nagios-plugins
apt-get install nagios-plugins-basic
apt-get install nagios-plugins-standard
all the conf stuff resides in:
/etc/nagios
