So, I have started toying around with my AppleTV and realized I wanted to make it a bit more sane for my environment.
1- Make it possible to ssh in to your AppleTV. You can do this with atvusb-creator/ (You can find various guides on how to do this online)
2- ssh appletv.local -l frontrow
3- sudo tcsh
I have a slower internet connection at home so desire to run all my web requests via my proxy-cache. The settings are hidden in /Library/Preferences/SystemConfiguration/preferences.plist . I went ahead and copied the file and made a backup (always a good idea!) then performed a few edits, replacing the section that reads Proxies with the following (naturally updating my IP address accordingly).
<key>Proxies</key> <dict> <key>AppleProxyConfigurationSelected</key> <integer>2</integer> <key>FTPPassive</key> <integer>1</integer> <key>HTTPEnable</key> <integer>1</integer> <key>HTTPPort</key> <integer>3128</integer> <key>HTTPProxy</key> <string>IP.ADD.RE.SS</string> </dict>
Hope these things help you out.
