Subject [jira] Commented: (MUSE-91) Better handling of finding the right local ip address
Date Tue, 21 Nov 2006 12:47:10 GMT
    [ http://issues.apache.org/jira/browse/MUSE-91?page=comments#action_12451627 ] 
            
Jose Antonio commented on MUSE-91:
----------------------------------

I have this problem too with my current project. I need a service that generates a notification
with and EPR to a service that must be called at some point but when that EPR is generated
it gets the 127.0.0.1.
As the EPR can be modified before sending it, I can use the code above to work aroud this
while a better method to find the local IP is implemented. It's a shame that it's not going
to be resolved for the 2.1 release.

> An interesting problem surfaced recently. If you want to figure out an EPR (for subscription,
say) you'll need to get the ip address. However, InetAddress.getLocalHost().getHostAddress()
can bind to a local interface and get either a loopback address or a 192.168.X.X address...
this is bad. Here's some code to look for the first non-loopback and non-local address.

> String hostAddress = InetAddress.getLocalHost().getHostAddress();
> Enumeration interfaces = java.net.NetworkInterface.getNetworkInterfaces();
> while(interfaces.hasMoreElements()) {
> 	NetworkInterface nextInterface = (NetworkInterface) interfaces.nextElement();
> 	Enumeration addresses = nextInterface.getInetAddresses();
> 	while(addresses.hasMoreElements()) {
> 		InetAddress address = (InetAddress) addresses.nextElement();
> 		if(!address.isLoopbackAddress() && !address.isSiteLocalAddress()) {
> 			hostAddress = address.getHostAddress();
> 			break;
>          	}
>        }
