Networking and Zune

[Zeek]

Well after going threw all the XNA related things and the "internet on the zune" theory, I got to thinking, if we found out what port it tries to listen to when you are sending the picture, I could make a simple java server to pick up any connections and continue from there. I mean we can already sync with the pc per say, wirelessly and that might just be the port we need, idk, but I'm gonna do some more digging into this. I mean we don't need a browser per say but having a online game (for games like valgard's fate), would be awesome to have.


So if anyone has some input on this or comments please reply!


Edit:Well I decided to check out some packets when the zune is syncing wirelessly, and when the zune, is just sitting idle connected wirelessly, I found out some interesting things.

One:My zune has a static IP.
Two:I got the port it uses, 15740
Three:While analyzing the packets going from and to my zune, I found that the zune when connected turns in a UPNP device, if you have a router you know what they are, so I decided to go deeper into the packets.
Four:The zune, yes was going onto the internet while it was sitting there idle, I thought that was pretty neat, actually it was connecting to my SERVER computer which has the internet on it, and idk what it was doing from there but it was communicating with the ICS(Internet Connection),

Five: As I was typing up this post I found a webserver on the zune, yes that's right, a webserver, http://my_zunes_ip:1040-1045/Device.xml, from there I could pretty much get all the info that was on my zune, even a image location, so I decided to go snooping around to see if I can find a folder of stuff, or perhaps another XML with like a directory of this webserver of stuff.


I'll try and keep you guys up to date on my progress here.

I gotta admit that's pretty awesome. But I don't see how this will really help trick the zune into believing a pc is a zune, since it goes ad hoc.

[Zeek]

Yea well, it would just need a pc to connect, but yea I thought it was pretty neat to, but I looked into and it's just a UPnP server, so I don't think it was exactly what we were looking for.


And another thing to, if I am able to isolate what the zune looks for when you are in a game, but one thing I am still puzzled about is, how the ad-hoc network works between the zunes, IP wise, if my zune already has a one pre-set to the wireless card in there.

Cool.

When you're using wireless sync, the PC discovers the Zune through UPnP, then initiates a connection over MTP/IP (which, as the name looks like, runs the MTP protocol over a network). I'm not sure about the role of device.xml though.

[Zeek]

The Device.xml is for the Zune Software, just like there is a ign.xml for my router's upnp server. I was gonna try and make a text based network game from computer to zune but since the network protocols were diff it wouldn't let me compile create a session to listen or join a session. So stumped for now... Still need to figure out how the zune to zune works, I'm hoping some day I'll get another zune here so I can test network lol, and maybe output some stuff but I doubt it.

[Red Sky]

it's a good outlook. I think you've delved deeper into this than anyone else on the zune boards, and possibly elsewhere. Good luck is all i can say, you're results are somewhat promising!

That's kind of funny. I just ran a packet capture while doing a wireless sync and found this thread by doing a Google search for Zune 15740. I'm going through the packet capture now and am wondering if it might be possible to sync wirelessly using a third party app using the information grabbed with the packet capture.

As far as I know, the same barriers exist to wireless syncing with 3rd party apps as USB syncing. The Zune software and the Zune itself must complete a certificate handshake before any data can be written to the Zune. This handshake should be possible to reverse engineer, but that isn't easy.

I thought I saw something were you can run Linux on the Zune.

[MehStrongBadMeh]

Nope, it has never been successfully pulled off. Your post also has no relevance to this thread.

keep up the good work Zeek! I have long waited for someone to make this happen!
