Remove need for changing DNS settings. #45

SMTDDR · 2014-06-29T17:00:17Z

It would be nice if you created a domain name the same string length as "nintendowifi.net" that will point to your server and be accepted by your apache config when it sees that host in the Request's Host header; doing the same thing it would have if the host said "nintendowifi.net". I could make a Riivolution patch that replaced all "nintendowifi.net" with "ramen.altwfc.net" and thus people won't need to change their DNS settings. They'll just start riivolution and I'd provide a patch called "Use altwfc servers".

Background

TL,DR - Make the subdomains ".ramen.altwfc.net"(same string length as "nintendowifi.net") point to altwfc's IPaddress and Hostname ".ramen.altwfc.net" be accepted on your apache config the same way "nintendowifi.net" currently is.

Right now, this is what I see:

Anything that makes accessing the server easier is good in my books. Especially since this is just an Apache configuration, it should be trivial to add.

Keep in mind that some games have their own servers located on non- nintendowifi.net domains, and would require their own special patches for this to work.

SMTDDR · 2014-07-05T08:20:27Z

@mm201

Really? ugh, I want one riivolution patch that resolves this completely. Could you give me an example of URLs of any game that talks to servers not ending in "gs.nintendowifi.net"?

mm201 · 2014-07-05T17:23:25Z

Pokémon Platinum and onward communicate with pkgdsprod.nintendo.co.jp for Global Terminal things (battle videos and some gimmicks). Pokémon Black/White and onward communicate with pkvldtprod.nintendo.co.jp for anti-cheat. They also communicate with one of several subdomains at pokemon-gl.com for Game Sync. (The subdomain depends on the language of the game.)

ghost · 2014-07-05T17:27:40Z

yes,because every server have a different communication,like in black & white,use the pkvldtprod for anti cheat,but nobody likes that

mm201 · 2014-07-05T17:31:46Z

It doesn't matter if you like it. The game hangs and returns an error message if there's no response from the server.

SMTDDR · 2014-07-06T15:06:17Z

@mm201
Ah, so just 2 domains? nintendowifi.net and nintendo.co.jp that you know of?

mm201 · 2014-07-06T20:52:05Z

There's a third one in there, pokemon-gl.com.
Also, it's only Pokémon I've been researching. Other games could be using anything.

I wanted a generic riivolution patch. The info you have given me makes it clear that each game may end up needing its own specific changes. Closing this github issue, a *.ramen.altwfc.net domain resolve isn't going to accomplish what I hoped.

mm201 · 2014-07-07T14:12:17Z

There's no reason you can't make a patch that works for the generic games without special servers. I don't even know which (if any) Wii games use special servers. A general purpose patch could still work 99% of the time.

SMTDDR · 2014-07-07T15:29:40Z

@mm201 ....oh...these servers you've mentioned are only for Nintendo's handheld systems that you know of? I'm hoping all WII games stick with "gs.nintendowifi.net".

mm201 · 2014-07-07T15:33:40Z

See the compatability list for a list of games which are working with only basic *.nintendowifi.net connectivity.

Requiring DNS or a custom patch for a small subset of games isn't that big a problem.

SMTDDR · 2014-07-07T15:37:55Z

@mm201
Interesting. I guess that makes sense, all those games are working when pointed to altwfc's DNS which only redirects nintendowifi.net requests afaik. I sure would like to see the network captures of the games that don't work on that list.

mm201 · 2014-07-07T15:41:20Z

The thing is, there are several different reasons a game might fail. Requiring a custom server is only one of them. They might require a custom gamestats server (custom, but hosted under nintendowifi.net), or use unimplemented parts of the Gamespy protocol.

Edit: And altwfc is redirecting pkvldtprod.nintendo.co.jp requests to my server.

SMTDDR · 2014-07-07T15:57:22Z

@mm201
True... but still curious to see if any of them is a simple'ish fix.

Edit: And yeah, I forgot that altwfc deals with more than just WII games.

Excellent,

Looks like *.altwfc.net points to your custom server, this is good enough for now to experiment making a riivolution patch that'll replace "nintendowifi.net" with "ramen.altwfc.net". The only catch now is the fact that the game will set the request header as Host: ramen.altwfc.net, which will result in a 404 response from your system because you're expecting naswii.nintendowifi.net but I'll have a proxy setup such that the riivolution patch will replace https://naswii.nintendowifi.net with http://altwfc.ramen.dontrush.me so I can get all the requests, change the header and send them to altwfc's server.

All the non-naswii requests, I can patch .gs.nintendowifi.net into .japan.gs.altwfc.net ...same length string.

SMTDDR · 2014-07-10T10:14:40Z

Okay, riivolution patch works... I can get online without changing my DNS settings.

https://www.cloudshark.org/captures/d638a18f5333

The only catch is altwfc's apache rejection of naswii.ramen.altwfc.net as a valid host request headers. If that was fixed, then there would be no need of my custom server to rewrite that request.

SMTDDR · 2014-08-28T13:36:40Z

I guess this won't be happening

kyle95wm · 2014-12-14T06:01:15Z

It's sad really, I was really hoping we could have something like this

mm201 · 2014-12-14T06:03:37Z

It's easy to add, you just need to kick the right person. Probably Nagato or Eearslya.
