	public static String getLocalIP() {
		String ip = "";
		try {
			if(isLinux()){
				Enumeration e1 = (Enumeration) NetworkInterface
						.getNetworkInterfaces();
				while (e1.hasMoreElements()) {
					NetworkInterface ni = (NetworkInterface) e1.nextElement();
					if (!ni.getName().equals("eth0")) {
						continue;
					} else {
						Enumeration e2 = ni.getInetAddresses();
						while (e2.hasMoreElements()) {
							InetAddress ia = (InetAddress) e2.nextElement();
							if (ia instanceof Inet6Address)
								continue;
							ip = ia.getHostAddress();
						}
						break;
					}
				}
			}else{
				ip = InetAddress.getLocalHost().getHostAddress().toString();
			}
