             Some of you may face error during completing Lab 06. I am afraid may be this is because of the Nagios version that you are using currently. By default, suse 10 will give you Nagios ver 1.3. In order to upgrade the version of Nagios, here are the step that might help you. I also provide you the latest ver. of Nagios (ver 3x) as below:

1. Stop Nagios
2. Backup your existing Nagios installation
• Configuration files
• Main config file (usually nagios.cfg)
• Resource config file (usually resource.cfg)
• CGI config file (usually cgi.cfg)
• All your object definition files
• Retention file (usually retention.dat)
• Current Nagios log file (usually nagios.log)
• Archived Nagios log files
3. Uninstall the original RPM or APT package
4. Install Nagios from source by following the quickstart guides for SuSe
5. Restore your original Nagios configuration files, retention file, and log files
6. Troubleshoot and repair error if any
7. Replace all your configuration files (if possible)
8. Verify your configuration and start Nagios

Nagios ver 3.2.3.tar.gz

Step to install Nagios from external source

1.       Download latest version of nagios. Example nagios.3.2.3.tar.gz

2.       Extract the Nagios source code tarball

tar xzf nagios-3.x.tar.gz

cd nagios-3.x

3.       Run the Nagios configure script, passing the name of the group used to control external command file permissions like:

./configure --with-command-group=nagiosadmin

//./configure --with-command-group=nagcmd

4.      Compile the Nagios source code.
