I recently installed fedora core 5 on&nbsp; two systems.<br><br>Is the system/administration/services GUI thing discussed in the documentation somewhere? (I can't seem to find anything except selinux.) I'd like to know a bit more about what the consequences of turning off some services might be. There is a terse description available in the tool, but it doesn't make it clear what will happen if I turn 'em off. For instance, I don't really know whether I need to &quot;Listen and dispatch ACPI events from the kernel. (acpid)&quot; Hate to just turn them all off &amp; see what breaks.
<br><br>Also, I'm running nmap and lsof to try to figure out my open ports so I can close those I don't need and tell the firewall about the ones I do need. <br><br><br><div><span style="font-size: larger;"><b>nmap -sT -O mysystem ;&nbsp;
