Better handling of finding the right local ip address
-----------------------------------------------------
Key: MUSE-91
URL: http://issues.apache.org/jira/browse/MUSE-91
Project: Muse
Issue Type: Improvement
Affects Versions: 2.0.0
Reporter: Andrew Eberbach
Assigned To: Dan Jemiolo
Priority: Minor
Fix For: 2.1.0
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;
}
}
}
