Connecting Ps3 To Powerbook Interweb

I’ve been trying to share media between my Powerbook and Playstation 3 so that I can keep all of my audio and video files on my external hard drive, and watch them on the TV. Haven’t figured it out yet (looks like 3rd party software is necessary). But in the process, I’ve gotten it so my PS3 is now online, wirelessly connected to dial-up! Woo!

So far I’ve been able to log into the Playstation Network and use the PS3 internet browser, but no multiplayer inside a game (keeps timing out, understandably). Also doesn’t help that all of my games are out of date and ask to download updates before connecting. It’d be a riot if I could attempt multiplayer over dial-up though.

Anyway, it took a lot of trial + error to get my laptop to share internet via AirPort (using “DHCP” – whatever that means), so here’s my former stumbling block:

Make Internet Sharing DHCP work with an Xbox/Xbox 360 (or PS3!)
(for OSX 10.4+)

1. Start Internet Sharing if it’s not already running.
2. Open NetInfo Manager, located in /Applications » Utilities. Authenticate as an administrator using the lock icon in the lower-left.
3. Navigate to the /config/dhcp node (so that dhcp is selected in the browser pane).
4. In the lower pane, find the reply_threshold_seconds property and change its value from 4 to 0.
5. Quit NetInfo Manager and then restart your Mac.
6. After the restart, open NetInfo Manager again and confirm that reply_threshold_seconds is still 0.

Hope it helps someone!
