Nagios installation issue

[FTL Nagios]

Start again and follow

http://nagios.sourceforge.net/docs/3_0/quickstart-ubuntu.html

Change the version numbers to whatever version you are installing obviously
as to whats wrote in that guide as its quite old.

Also you need to install "apt-get libssl-dev" before you install the plugins
or the 1.4.16 plugins will fail to install properly

Job done.
