I've two PS3s, one retail slim and one JB phat, I don't care about any of this, should I?
Its unlikely Sony will do anything to harm your console more than they already do (no going online). In certain countries it would be illegal for them to alter the working condition of your console without your agreement. Sure - they could probably put a message up on screen saying that you must upgrade to 3.50 etc, but they already do that.
Seriously think about it... they already have a system to get "sheep" to upgrade past 3.41... they would have already made their move if they could have done so.
Just think about it... Yes, your PS3 connect to Sony's servers.... why?? To check for firmware updates and remind you to update... any other reason? No.
Really... You all know Sont have had the most secure console since launch and they would do anything to keep it that way.... why all the court action and involve the law if they can simply use some sort of Ban Hammer??
There is no BAN HAMMER with Sony.... You just cannot get on PSN without updating firmware...
Just think about it some more before getting carried away by someone who see's communication between your PS3 and Sony and jums to conclusions... No need to thank me for pointing it out to you all.
What worries me is the possibilities of forced updates, I don't want to loose my 3.15! If I do I'll probably sue Sony for forcing an update which removes an advertised feature.
Edit: Don't get me wrong though, my console has never been jailbroken, I just want Linux.
If you miss putting a server on a whitelist, the worst that can happen is a game will just fail to update. It's much safer.
I understand what you're trying to do and appreciate your work on assembling the blacklist, but going the other direction seems like a better idea to me.
Let's say that PS3 will try to reach 4 different URLs during the game update - this gives you already 16 (or let's say 15) combinations of enabled and disabled addresses. With 5 URLs this numer basically doubles to 31 and so on and would be quite pain doing all this every time you'd like to update the game.
Other option is to simply disable HTTPS communication / port for your PS3 as both PSN login as well as most of the spying transfers is encrypted or pass it via customize proxy and simply block / throw away all SSL communication.
This entire thing is blown out of proportion. Banhammer? When we can't get online anyway? Ban from game updates? Then just install them as pkgs.
When no one fully understands the nature of the info sent when our ps3's "phone home" I for one don't care to find out the hard way. It took me all of 2 min to copy/paste these URL's into my router.
Wanna be one of the first victims when/if someone figures out a way to get us online again? Bury your head in the sand and let your hardware keep telling on you. Problem solved. No offense to anyone who is skeptical but enough time on the 360 scene and you learn to be precautionary.
PPL there found out the hard way about your offline unit logging backups in NAND and then phoning it all in the second you connected. If it takes very little of my time to do why not do it even if it never does any good? Being permabanned is a high price to pay and I'd never stop kicking myself if it turned out preventing it was something that was simple. IMHO it pays to err on the side of caution.
