Compiling Nagios from source

This article is a quick log of my adventures while compiling and running nagios from source. The context is that I needed a solution to monitor my machines at work, but did not have root privileges on the machine I was to use. Therefore, the install we will be documenting is in this particular context:

  • User does not have sudo privileges.
  • User has mailing privileges.
  • User can host files on the apache httpd server.

Connecting to remote X server

This article will show you how to connect to a remote Unix host in graphical mode, by using two different methods. We'll explore X forwarding (with Cygwin/X) and VNC. As an example, we will show how to connect to the UQAM university network. Please substitute proper server information with your own, if you are not an UQAM student.
