java 获得 ip 地址

一般情况获得本地所有的ip地址：
try   {
InetAddress   address   =   InetAddress.getLocalHost();
System.out.println(address.getHostAddress());
String   name   =   address.getHostName();
System.out.println(name);
InetAddress[]   addresses   =   InetAddress.getAllByName(name);
for(int   i=0;i <addresses.length;i++)
System.out.println(addresses[i].getHostAddress());
}
catch(UnknownHostException   uhe)   {
System.err.println( "Unable   to   find   IP ");
}
}
try   {
InetAddress   address   =   InetAddress.getLocalHost();
System.out.println(address.getHostAddress());
String   name   =   address.getHostName();
System.out.println(name);
InetAddress[]   addresses   =   InetAddress.getAllByName(name);
for(int   i=0;i <addresses.length;i++)
System.out.println(addresses[i].getHostAddress());
}
catch(UnknownHostException   uhe)   {
System.err.println( "Unable   to   find   IP ");
}
}
但是以上方法在linux下是不行的，
