"failed to get MAC address for machine"

here is the jist of things.
installed leopard and have it pimped out to my personal specs. I like where everything is and how things are working. No issues. just so you know, i only use WIFI for internet, i share with the guys upstairs. In order to get wifi on my machine, i use a USB dongle. works great no issues with it ever, well until i physically broke it. No big deal. So i replaced it with another one, different drivers/chipset worked.. And since i installed leopard i only backed it up once with TM, i dont care for daily/hrly backups, weekly is fine for me. Now after 2 weeks and a new usb network card. TM gives me an error. i click on the little red i and it says "the backup volume could not be found" so googled and searched the forums not much help, so i tried and formated my ext drive repaired and click on TM again, same error. In the error log in console, right after i turn on TM i get this error, "failed to get MAC address for machine" then 180 secs later, TM fails. again, and again.
Can anyone tell me where i can find what MAC address its looking for??? ethernet has never been plugged in to my machine ever. its only been online via USB wifi. Im really lost here, i dont know what i can do.. im sure if i try another drive ill get the same error. please help if you can.. much appriciated.
Jamie

yeah i get a 'failed to get mac address' message too. what's weird is that it seems that leopard 'broke' my ethernet (there was no mac address, couldn't connect to the internet through ethernet after a clean install), and then 10.5.2 'fixed' it. for some reason, i have an 'ethernet 2' heading in system preferences that works correctly and has a mac address and everything, while the regular 'ethernet' tab doesn't work at all. however, i still get this time machine error. i don't understand why time machine is so incredibly fickle. sorry, i'm really of no help to anyone, other than adding another voice to the frustration.

How to get MAC address from client machine ?

Hi dear,
We are implementing security measures for a banking system, so it is required that we track the MAC address of the registered clients along with other parameters. How do we get the MAC address from client machine using ADF or running scripts in client side?
thanks all

Hi,
Welcome to OTN.
Your question has nothing to do with ADF as such. Googling would give you plenty of such topics.

Thanks in advance

You have several ways under *nix
ifconfig -a | grep HWwill output something like
eth0 Lien encap:Ethernet HWaddr 00:11:FF:74:FF:B4combined with Runtime.getRuntime().exec("")and Process.getInputStream()you should be able to read it easilly.
Under Windows (and Linux of course) try jpcap (http://sourceforge.net/projects/jpcap)
You can also use jnative as a generic tool (http://sourceforge.net/projects/jnative)

How to find MAC address for WAN port for Airport Express 2nd Gen.

The New Airport Express has a LAN and a WAN ethernet ports. How can I find the MAC address for the WAN ethernet port as my Service Provider needs it for provisioning....I can fid MAC address for Ethernet and for two wireless 2.4 & 5GHz but not for WAN ethernet port using Airport Utility 6.1

Many thanks for the swift response. However, there is no WAN MAC address on the box or on the device anywhere. I even used magnifying glass to find one .
The airport utility shows only three mac addresses. One for 2.4GHz, one for 5GHz and one fo the ethernet (LAN port) whereas there is another ethernet port in the device mentioned as WAN port and I am still not able to find the MAC address for the WAN ehternet port for Airport Express (2nd Generation).
Will appreciate a response to make th device work wiht my service provider as providing them the WAN mac address is a must. Had there been an option for cloning mac address, the issue would have not been there.
Many thanks again - in advance.

How to get Mac Address of Remote Computer

Hi All,
I tried to find out a solution for finding Mac Address of a remote system, then first i tried with finding it with local address using the following code it works fine for me.
public class MacAddressFinder {
     public static void main(String[] args) {
          try
               InetAddress ipAddr = InetAddress.getLocalHost();
               System.out.println("Current IP address : " + ipAddr.getHostAddress());
               NetworkInterface nwIntf;
               try
                    nwIntf = NetworkInterface.getByInetAddress(ipAddr);
                    byte[] hwAddr = nwIntf.getHardwareAddress();
                    System.out.print("Current MAC address : ");
                    StringBuilder sb = new StringBuilder();
                    for (int i = 0; i < hwAddr.length; i++)
                         sb.append(String.format("%02X%s", hwAddr, (i < hwAddr.length - 1) ? "-" : ""));
                    System.out.println(sb);
               } catch (SocketException e) {
                    e.printStackTrace();
          catch (UnknownHostException e) {
               e.printStackTrace();
But when i tried this piece of code in jsp with the following code i am getting NeworkInterface object value as null and there by i am unable to get the Mac Address of a remote computer.
InetAddress ipAddr = InetAddress.getByName(request.getRemoteAddr());
NetworkInterface nwIntf = NetworkInterface.getByInetAddress(ipAddr);Can you please suggest me how to find out the Mac address of remote system?
Thanks,
Uday

first of all, NetworkInterface only exposes the NetworkInterfaces of the local computer. secondly, you cannot find the mac address of an arbitrary remote computer. that information is not available outside of the local subnet. and java doesn't expose a way to discover it even for computers on the local subnet.

How to get delivery address for PO

I have a problem.
I am working on a SAP Script , which is for PO(Zmedruck_po) , which is a copy of
MEDRUCK.
I am asked to print the delivery adress in a window .
The scenario is like this .
In ME23N , under item details , there is a tab called DELIVERY ADDRESS
this has option to enter the adress details or a delivery number in the address text box .
If the address number is present i have to print that address , else i have to print the address which is entered in the delivery address tab.
If the delivey address number is there i have no problem in printing it ,But if address number is not there ,I need to know how to get the delivery address,
is it the plant address, company code address ... ?
I debuged ,but could not find out.
Can anyone help please .

Hi,
I don't know the table that is used to store the manual address on the PO but if you get your ABAPer to checkl the code in ME21N they should be able to tell you.
Or better still, if one of the other experts here know the table that is used they will post the solution.

How to get mac address?

I have used NetworkInterface.getNetworkInterfaces() for get list of interfaces
but under xp I not read interface informations.
Is possible that the problem is permission level of user?
Thanks.

Some call in Java are OS dependent and work better on some OS than other. If there is a permissions issue it is at the OS level and Java would not be aware of it. (But I doubt this is the case)
It is possible that information is not available under windows.
However you can call "ipconfig /all" and parse the MAC address from that.

How to get MAC Address of a stolen laptop by using Serial number?

Hi my Lenovo G560 laptop was stolen on 17/04/13. I have the serial number. In order to trace the laptop, I need the MAC address. Unfortunately I don't know the MAC address of my stolen laptop. My question is, is it possible to get the MAC address by using serial number?
Serial Number: xxxxxxxxxx
Moderator Note; s/n edited for member's own protection

hi Subrahmanya,
Sorry to hear about your trouble. Unfortunately, the only way to get the MAC address is to run a query on the unit (physically or or remotely). Using the serial number to query information on the system will list the devices that are included on the unit (this doesn't include the MAC address).

How to get MAC address list and HDD serial number from Windows and MAC machine?

Hi,
I'm developing a AIR application. I'm implementing the product key mechanishm. I need to identify the users' machines uniquely. I chose MAC address would be a better way. But a computer has list of MAC addresses including LAN card and Wi-Fi card addresses. So, I need to get the list of available MAC addresses from the computer and the Hard Disk Drive's serial number. HDD serial number would be helpful to cross verify the identity.
I'm able to get the MAC address using NetworkInfo class. But I need to get a list of available MAC addresses and HDD serial number.
Is there any classess to accomplish this task?
Thanks in advance.

See if this link can be of a little use to you.

How to get the address for saved context for the managed code in the 64 bit processor by such as .cxr

It is possible that the callstack at the time the exception was thrown is different from the callstack getting by running the ~*e !clrstack/~*k, so how to get the exactly exception
callstack ?
If it it x86 unmanned code, I can use the tips "s -d esp L1000 1003f" mentioned in the following article, but my case is
x64 manned code, I even can't find the ntdll!KiUserExceptionDispatcher in any of the callstack, any idea or reference is very appreciate.

I agree with James if you're looking for the most recent exception or want to print a specific exception. You can also use DumpHeap to filter out all exception objects currently in memory and DumpStackObjects to list any exception objcets present
in the stack on the current thread if you're probing for exceptions. The /d option, which provides DML output, works with many SOS commands as well and makes browsing through objects quicker.

If you didn't write it down the first time it will almost next to impossible to find it also this doesn't gurantee in any way you can get your laptop back either. MAC is only good if you wrote it down or registered it but if none of this is written down. And if you don't have tracking software installed the chances of getting it back is harder to get it back. So unless you see it being sold by someone or online this is the only real way you can track it down.
