The quoting in this thread is so confused I'm not going to try and unravel it. The Sytem -> Preferences -> Startup Applications menu item is only for desktop applications running in a session. That is quite a bit different than system services, sometimes called daemons. Typically the radius service is installed under the name radiusd following the convention that daemons have a "d" appended to them. That means you're trying to control a system service not a session based desktop application. This is done at the command prompt level with chkconfig or via a gui with system-config-services. You might have looked at: http://wiki.freeradius.org/Red_Hat_FAQ#How_do_I_start_and_stop_the_FreeRADIU... If you build from source and you don't know what a System V Initscript is then the algorithm is: 1) Stop 2) Install the pre-built package with all this stuff already figured out, tested, and done for you so you don't have to learn how to build from source *and* integrate with the OS, all the while making a lot of learning curve mistakes. Installing pre-built packages typically takes 1 minute of your time. Wasn't that easier? Fedora, RHEL, and CentOS all have current packages available.
