Homebrew RELEASE yaDNS-NX - Yet another DNS for connect your Switch to your WiFi without internet - In a docker

[Dinoster]

Awesome release buddy. I was seraching for something like this for a long time.
One question: Any way to test that it actually works after putting the command?

1: check you have passed both local and Internet network checks.
2: Enter eShop (you should fail to load). If you successfully entered eShop then i think you messed up somehow.
3: FTPD and you are able to transfer files to and fro just fine.

Only problem I got is if you have docker set up to start when you start windows after you power cycle your pc the script doesn't take for some reason and you gotta restart docker. So I just turned off start at login and start it manually.

Is it somehow possible to savely play fortnite on a modded switch? Because my friend has a switch and want to mod it but also want to play fortnite.
And i have a second question: Can i run this on a pi zero?

You cannot play online with this. Your switch will not know what internet is Also is not safe to play any online game if you have modded your switch.
And with the second question, yes, I didn't tested on a RPiZero but it should run docker, so it should work.

This worked great for me, despite this being my first time using Docker, thank you for the software and concise guide. This makes it easy to transfer files through FTP to the Switch while completely blocking it from the internet using my router's firewall.

I would like to implement this kind of functionality in my hacked zsun (since it has sufficient space, and my A5-V11 injector dongle does not), but would like to use lighttpd instead of nginx. Any pointers on how to return proper headers for the query with lighttpd?

Never used Lighttpd, but you need to return a http 200 OK with the X-Organization header
Something like this

$HTTP["host"] =~ "^nintendo\.net$" {
  setenv.add-response-header = ( "X-Organization" => "Nintendo" )
}

And the same for nintendowifi.net, I don't know how can lighttpd return a 200, maybe it can work with a blank .html file or with a "Content-Type" => "text/plain" header.
That from the load balancer's side, but also you will need to serve a DNS server, I'm using bind9/named, I don't know if the zsun can serve a dns server or if can intercept or modify the client's queries.

docker start yadns-nx
Error response from daemon: driver failed programming external connectivity on endpoint yadns-nx (bf55661d97e9d2e2a362be6556934f999dc43df197e672ad0900ee96115b3f27): Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error (Failure EADDRINUSE)

Any clue what's happening here? MacOS, connected to internet via ethernet and connected to a local network (with no internet) via wifi. The wifi router is plugged in purely to send things from the Mac to the Switch, it has no WAN access or cables plugged into it or anything. Trying to use the Mac's wifi IP as the DNS. Switch will connect to wifi, but fails internet connection test so it won't let me use that connection.

It seems that you have something else running at the port 80. This docker needs to use the port 80 and 53. You need to check what service is using that port. Do a

lsof -n -i:80 | grep LISTEN

in a terminal or use netstat or another software to see if you have another process using the port 80. Also check if there isn't another instance of docker already running on that port.

Oh whoops, duh, I have apache running on my computer as a webserver. Hmm...can I just change the html file that I serve up (it currently says "It works!" which I think is just some default apache thing) to include the headers and OK 200 and whatnot, and just not have docker run on port 80?

edit: actually maybe I'll just change the port for apache, might be easier that way because I already know how to do it

edit 2: it worked, now im just gonna end up forgetting to navigate to a different port whenever i use my webserver within my home :-p also is 1.8MB/sec basically my max transfer rate here? seems painfully slow...but I guess I was mostly doing this for novelty's sake anyway...

You may not need my docker after all , editing your apache vhosts to manage *.nintendowifi.net and *.nintendo.net with OK 200 and the custom header should be enough, but you will also need to install bind9 for the dns side and you're done.

This docker shouldn't affect your bandwidth, it doesn't act as a proxy or any MitM. The service only responds when the Switch ask for nintendo's servers.

I will see what I can figure out.

The hacked zsun is running openwrt barrier breaker, and has a full implementation of both a DNS server and a full router + firewall implementation. (by default it uses dnsmasq, but bind can also be used. Has a 32mb internal flash, and more than enough processor and ram to run nginx, but I would prefer something lighter, hence the question.

Given the small size of the device (it's about the size of an SX dongle), and the fact that it has a convenient microSD slot (meaning it can function as a poor man's NAS/DLNA server), it is a nearly perfect appliance to live inside the switch's dock on the USB port. (the door will close easily with it installed.)

Before you ask, it is capable of connecting to an SSID, *AND* running another virtual SSID in STA mode, at the same time. The only caveat with that is that both need to be on the same channel. This means it can quietly be a man in the middle for the switch, and when tinfoil gets network install functionality, it can be the go-to device to put NSP files on for network installation.

It looks really a great device for the price and size.
Go for the dnsmasq+lighttpd combination, it should be a way to manage custom domains, something like this: https://github.com/RMerl/asuswrt-merlin/wiki/Custom-domains-with-dnsmasq

If you can run also a fusee-launcher listener then it's the potential ultimate device for Switch's hacking haha
+ DNS to block nintendo servers
+ Fusee launcher with interchangeable payload on the microusb
+ FTP and nsp vault

Do a custom 3D printed case and attach a usb C port

 

[Wierd_w]

Sadly, the device is not self powering, and is also too small for me to do the needed hardware modifications to make the connector face the host. This means it cannot be used as an injector dongle.

However, as a waystation for network installed NSPs, a place to stream all that meme-worthy anime from, and a place to do the DNS redirection/nintendo fakeout web services, it more than delivers.

I just used the following guide to get it to "more or less safely" connect to my local access point and do the network bridging with (and provide) the SSID it presents to the wild.
https://wiki.openwrt.org/doc/recipes/ap_sta

Now I just need to add the needed entries for dnsmasq, and configure lighttpd to return the correct x-organization string.

_______edit___________

Ok, OpenWRT wants so terribly to use uhttpd for LuCi, so I am gonna let it. I just moved it to an obscure port to listen on, then installed nginx.

dnsmasq is very easy to add entries for. Successfully set them up, and now nginx returns "ok" on http probes.

Just need to go unplug from the internet, and see if the switch likes the surrogate.

Thanks for creating this and posting the source. I had no prior experience with bind9, but managed to get it working on a debian server on my local network that was already running nginx.

 

[ShaytheStar]

Nice. My only question is...do I have to rerun the command and keep Terminal open every time I use this on my Switch? Sorry if that's a dumb question.

No, but you run the command to start yaDNS everytime you boot up or restart your pc.

Ah, all right. Thank you.
