upnp

I want to list my available upnp/dlna renderers on my local network in console mode. I can do that with gupnp but not in console mode gssdp-discover (from gupnp-tools) will list devices and services advertized over SSDP: gssdp-discover -i wlan0 --timeout=3 You can also specify the target (as uuid or a service/device type): gssdp-discover -i wlan0 --timeout=3 --target=urn:schemas-upnp-org:device:MediaRenderer:1 来源： https://stackoverflow.com/questions/18363833/how-can-i-list-upnp-server-renderer-in-command-line-console-mode-on-linux

Is there any way to use UPnP for NAT traversal on Android with a 3G/4G connection, and if so, is it carrier dependent? No, for the time being thee is no way to do that, for the simple reason that the mobile carriers don't use residential-class NATs - what they have is "Carrier-Grade NATs" CGN, see here http://en.wikipedia.org/wiki/Carrier-grade_NAT , and these devices have very different port allocation and management mechanisms from the residential gateways. See the Carrier-Grade NAT (CGN) related documents in this collection: http://www.scribd.com/collections/3292450/P2P PS there currently

I created a small program to test UPnP Multicast (Visual C# 2010 Express, running on Windows 7 Professional 64 Bit). I can receive the UPnP NOTIFY Messages from UPnP Devices in my Network. But when i send the M-SEARCH Message, i get no Answers. I have tested the same code on a iOS environment (Monotouch for iOS, running on a iPhone simulator on a Mac). There it runs fine and i get all the search responses from my UPnP devices. I can also see the M-SEARCH message from my windows program. It looks like Windows (or a Firewall?) is hiding the search responses. Any idea? Here is the code:

I'm working on a P2P application, and I need to get it to communicate through NAT Routers / Firewalls using UPnP. However, it doesn't seem that the .NET Framework includes support for UPnP. Is there a UPnP Library for .NET? C# or VB.NET? UPDATE: I have since found the NATUPnP 1.0 Type Library (NATUPNP.DLL) COM Component that is part of Windows (since Windows XP) that allows you to easily setup/maintain Port Forwarding using UPnP. I wrote an article with code samples here: .NET Framework: Communicate through NAT Router via UPnP (Universal Plug and Play) There is a COM library that's easy enough
