Honestly, there's no actual reason for me to ping the xbox. I originally got interested because I ran a quick nmap scan to see everything on my network and realized there was an IP address missing. I only saw:
192.168.1.1
192.168.1.2
192.168.1.4
That's when I tried to ping the Xbox and obviously it didn't work. For some reason I thought that it was because I had recently configured Arch with a static IP and I wasn't sure if for some reason that was affecting how I was communicating with other devices using DHCP. I actually forgot what I did that allowed nmap to see the xbox on the net, but once it showed up I tried pinging it and I got no response. Arping is the only thing that works.
Anyway, just thought it might make a nice discussion for the new gaming board.
EDIT: By the way, have you guys ever scanned an xbox for open ports with nmap? It's kind of hilarious how unsure it is. Nmap be all like:
"Um....I uh, I don't really know but, if I had to guess I would guess IIS.....or maybe NFS. Also, and this is just a guess but this OS is either IBM , linux 2.6, HP embedded, or Fujitsu Siemens ReliantUNIX"
