Try enabling these services on the server: Peer Name Resolution Server (Install through Server Management) Peer Discovery Server (Install through Server Management) Simple Service Discovery Protocol Service (SSDP Service) Then simply ensure that the Firewall Rules are modified; by default they block IPv4 / IPv6 Teredo Tunneling driver. IPv6 needs to be supported as it … Read more
Another interesting question that arises is of BitTorrent because they can work on any device and even behind a NAT. I am not able to get any explanation of how BitTorrent works. This statement looks like you assume that bittorrent needs full connectivity to operate. That is incorrect. Behind a NAT device you will still … Read more
No Already answered here for more details: Do websockets allow for p2p (browser to browser) communication? Update: The WebRTC protocol and API is making rapid progress and allows a Data Channel to be established between two peers (you still may need a STUN/TURN server for the initial NAT traversal and setup).
There’s no way around having to know at least one initial peer to discover more. Fully P2P protocols, such as Gnutella or Gnutella2, or the simpler Overnet (made famous by Storm Worm), are based on each client having a start-up list of a few peers. These can come off a web-based automated tracker for example. … Read more
No. Browsers can only initiate WebSockets connections, not receive them. The W3C browser API spec only defines how to start an outbound connection. You can make an application that would both initiate and accept WebSockets connections, but browsers do not do this. You might look at Pusher App which you could use to build a … Read more
Here on Stackoverflow are several topics about P2P connections in browsers: Will HTML5 allow web apps to make peer-to-peer HTTP connections? What techniques are available to do P2P in the browser? Does HTML5 Support Peer-to-Peer (and not just WebSockets) Can HTML5 Websockets connect 2 clients (browsers) directly without using a server (P2P) Is it possible … Read more
Here’s a bug report on the feature you’re requesting. It’s status is “reviewed” but I don’t believe it’s been implemented yet. http://code.google.com/p/android/issues/detail?id=82
With trackerless/DHT torrents, peer IP addresses are stored in the DHT using the BitTorrent infohash as the key. Since all a tracker does, basically, is respond to put/get requests, this functionality corresponds exactly to the interface that a DHT (distributed hash table) provides: it allows you to look up and store IP addresses in the … Read more
You can get the device model number using uname from sys/utsname.h. For example: #import <sys/utsname.h> NSString* machineName() { struct utsname systemInfo; uname(&systemInfo); return [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; } The result should be: @”i386″ on the simulator @”iPod1,1″ on iPod Touch @”iPod2,1″ on iPod Touch Second Generation @”iPod3,1″ on iPod Touch Third Generation @”iPod4,1″ on iPod Touch … Read more
Ok, they’re fundamentally a pretty simple idea. A DHT gives you a dictionary-like interface, but the nodes are distributed across the network. The trick with DHTs is that the node that gets to store a particular key is found by hashing that key, so in effect your hash-table buckets are now independent nodes in a … Read more
