How to config the Coherence to work under multiple physical interfaces surrounding?

[szhairui]

 Hi everyone!

I met with a problem while using coherence under multiple physical interfaces surrounding.

As we known, we can use "interface = eth0" to specify coherence to use the interface eth0.

But my problem is that I use one wired network interface and one wireless network interface.

How can i get the interface name to configure coherence to use the wifi interface ?

I can find the name "wlan0" on Linux , but I can see nothing about the interface alias such

as "eth0" on win32. Where can i found it?

And one more question, how Coherence determind which interface to use without the config file

or without the interface configuration item under multiple pyhysical interfaces surrounding?

Thanks for your notice. And any response will do me a great favour.

isn't there an 'ifconfig' command on Windows too? That should display
the available interfaces.

On Windows I recommend to use the netifaces module, the plain python
methods to determine the interface to use don't work that well there.

Atm Coherence does only support one active interface - this will change
on the way to 0.7.

We try first to get the hostname and resolving that to an IP address.
If that fails or we get a loopback address back, we switch to plan b.

On Windows we use the first interface we get back from netifaces and
use that IP address. On Linux/BSD/OS-X we try either to parse
'/proc/net/route' or the output of the 'route -a' command to
determine the interface used for the default route, which on
a single homed host is usually the interface to use.

Regards,
Frank

The similar command on win32 is ipconfig, but it doesn't show any network
interface alias.

That's really a good news for us who want a more powerful MediaServer
Framework.

BTW, can someone suggest any primer studying materials for a newbie of UPnP
just like me?
