Articles, notes and random thoughts on Software Development and Technology
Latest package is nagios3 – to install:
<code>sudo apt-get install nagios3
A good article on setup and config is here.
To restart the Nagios server after making config changes: sudo /etc/init.d/nagios3 restart
Part of the install instructions above told me to create a user ‘nagios’, but the default config is setup to allow ‘nagiosadmin’ access to monitor services. Accessing the wepages you get this:
<code>"It appears as though you do not have permission to view information for any of the hosts you requested... If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI and check the authorization options in your CGI configuration file."</code>
To fix this, edit /etc/nagios3/cgi.cfg, and replace ‘nagiosadmin’ everywhere with ‘nagios’ (assuming the user you created was called ‘nagios’)
If you startup Windows 7 beta and press F8, which used to take you into ‘Safe Mode’ in prior versions, the only option you have now is a ‘Repair Mode’ which attempts to do something to repair your install. While it’s running there is a dialog with a Cancel button on it. If you press it it says ‘The repair operation cannot be cancelled’. Hmm – that’s useful. A bit more polish needed there I think.
I read in the release notes that VirtualBox 3.0 has experimental support for DirectX – this is neat since some Windows games maybe able to now run inside a Windows guest running under VirtualBox. The fine print in the 3.0 manual however mentions you need to install the Guest Additions into Windows when it’s running in safe mode otherwise the DLLs get overridden.
