Host changing MAC of guest

Hi, this is beyond belief. The ipconfig in guest shows MAC address a, and the host has MAC address b. However, the guest reports that dhcp sent it an address that was already in use. Upon checking the log of the router, I realised that it DHCP server recieved
the request from address b, which is the host's MAC. Any ideas on why this is happening? I have tried changing routers but the symptoms are still here.

Yes, Hyper-V and wireless adpaters is tricky, you should read Ben's article about that

  • Ovmcli change ip on guest machine (running Windows XP)

    Hello,
    I'm new to OracleVM but find it very useful.
    We had previous expierences with VMWare virtualization in our company
    (VMWare server 2.0). It had VMWare tools which included cli (command line interface).
    I need to change IP address of Windows XP guest machine.
    To be exact: our guest machine is running windows XP, our host is Oracle VM.
    We want to change IP from let's say: 10.60.60.200 to 10.60.60.201 on our guest machine running XP.
    In WMWare we used:
    $command = "netsh interface ip set address LAN static 10.60.60.200 255.255.255.0 10.60.60.1 1";
    and a command that fired the action $command:
    vmrun -T server -h HOST_IP_ADDRESS -u HOST_USER -p HOST_PASSWORD -gu GUEST_USER -gp GUEST_PASSWORD runScriptInGuest "DATASTORE TEMP/xxx.vmx" cmd /c & $command;
    Is there something similar to "runScriptInGuest" or is there any other way to change IP of guest machine in Oracle VM?
    I tried to use
    ovmcli with:
    vm nic conf
    but the options don't include changing IP.
    As far as I can see there is only:
    --serverpool_name
    --vm_name
    --nic_name
    --new_nic_name
    --bridge
    --rate_limit
    --enable_qos
    --disable_qos
    options available for configuring network interface adapters.

    The problem with changing IP inside the virtual machine (windows XP) is that
    we use dynamic virtual machines. By 'dynamic' I mean that we have a set of templates that
    we clone, start, configure and then run application tests on them. The purpose of all
    this is that we want to have identical operating environement for all tests. In this way
    we can relate to results as done on exactly the same computer.
    The whole process (cloning, starting, configuring, restarting, running application tests and then pausing VM) is done
    from scripts - so we CANNOT just manually log via VNC into machine and change it's IP.
    We tried to use STAF (http://staf.sourceforge.net/) but it operates on IP
    so we can run with this tool any task except changing machine's IP.
    (STAF doesn't deal with the change of IP in time.
    Apart from this it sends response with new IP when
    server excepects response from old IP).
    Summerizing - runScriptInGuest from VMWare solved the problem for us
    because it ran a CONSOLE command inside Windows Guest
    which changed the IP. runScriptInGuest doesn't rely on
    machine's IP so everything ran smooth.
    Is there any other way to change this ip
    from SCRIPT. I mean some way to run this command
    remotely on windows or do this through OracleVM virtual machine configuration ?
    I hope it clears the question.

  • Change MAC address on Intel Mac?

    Is it possible to change the MAC address of an Apple computer using an Intel chip and if so, how?
    Open Firmware on PPC machines made it easy. I don't know about EFI.

    Hello Kappy,
    Why is it not a good idea to change the MAC address?
    Thanks Kevin
    Because it is intended to be a globally unique identifier of hardware. The MAC address can be changed on modern systems but why? See here for more info http://en.wikipedia.org/wiki/MAC_address
    Here are some reasons a person may want to change their MAC address. None of them sound like legitimately valid reasons.
    From http://www.irongeek.com/i.php?page=security/changemac
    To get past MAC address filtering on a router. Valid MAC      addresses can be found by sniffing them and then the deviant user could      assume the MAC of a valid host. Having two hosts on the same network can cause some network stability problems,      but much of the time it's workable. This is one of the reasons why MIC      Address filtering on a wireless router is pointless. An attacker can just      sniff the MAC address out of the air while in monitor mode and set his WiFi      NIC to use it. Interestingly, a lot of hotels use MAC filtering in their      "pay to surf" schemes, so this method can be an instant in for cheap skate      road warriors. 
    Sniffing other connections on the network. By assuming      another host's MAC as their own they may receive packets not meant for them.      However, ARP poisoning is generally a better method than MAC spoofing to      accomplish this task.
    So as to keep their burned in MAC address out of IDS and   security logs, thus keeping deviant behavior from being connected to their   hardware. For example, two of the main things a DHCP server logs when it      leases an IP to a client is the MAC address and host name. If you have a      wireless router look around on it's web interface for where it logs this      info. Luckily there are tools to randomize this information (MadMACs).
    To pull off a denial of service attack, for instance   assuming the MAC of the gateway to a sub net might cause traffic problems.      Also, a lot of WiFi routers will lock up if a client tries to connect with      the same MAC as the router's BSSID.

  • Can't change MAC address of my wireless card on Windows XP

    Dear Forum Members,
    I have recently bought a notebook, Lenovo IdeaPad G550L (I haven't found section for the G series here on the forum) and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly changed MAC address. I installed the recommended driver, available from Lenovo's website, version 5.10.38.14. I tried the common way to change the MAC address, went to Control Panel -> Network Interfaces -> Broadcom Wireless Network Adapter -> Configure... -> Advanced -> Locally administered MAC address, and changed it to a different address (without ":" or any separator characters). Unfortunately this common solution won't work at all. Although, no error messages are produced when changing it (so it seems successful) my wireless router shows me the original MAC address of my integrated wifi card. Tried to restart my computer, my router, everything.
    * Tried different drivers, downloaded a driver from HP which had a separate wireless configurator, Broadcom Wireless Utility. It worked like the driver from Lenovo (except this one hasn't got the utility), but I was still unable to change my MAC address.
    * Tried a different driver from SoftPedia, version 5.10.79.14 (this is newer than Lenovo's), it didn't work either.
    * Tried Nathan True's MACShift utility. It seemed to change the MAC address, but my router showed the original, so it didn't.
    * Tried to look for official Broadcom drivers on www.broadcom.com but found nothing for BCM4310.
    * Finally, I booted my alternative OS, the latest Ubuntu Linux, and used the kernel driver b43 for my wireless adapter. I tried to change my MAC address using the command ifconfig wlan0 hw ether .... and connected to my network. It worked, my router showed the changed MAC so the hardware (or the firmware) is capable of doing this by the right driver/firmware.
    I tried to address Broadcom with the issue, sent them a letter like this post they replied that they are not competent, they wrote the following (I guess this was an automatically generated message because it got back in 10 seconds ) from [email protected]:
    "As the chipset supplier, Broadcom provides driver support to our customers - the manufacturers of wireless devices - that ultimately provide products to end customers, such as wireless LAN vendors, cable modem vendors, and notebook providers. It is up to these manufacturers to provide product-specific drivers and software support to their end customers. Please contact the manufacturer of your wireless device for their current drivers"
    Then I addressed Lenovo with the problem, their answer:
    "Dear ******,
    Thank you for contacting Lenovo, the makers of ThinkPad and ThinkCentre products. As I understand, you have purchased a Lenovo IdeaPad G550L and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly change MAC address.and you would like to know is there an official driver for Windows XP that allows you this basic feature like b43 in Linux. We apologize,Please do speak with our Idea pad technical Team at 877-453-6686 Option 1-2-1-2 for further assistance.
    If you have further questions or concerns, please feel free to contact us at 866-42-THINK (84465) option number 2. We will be happy to assist at that time.
    Once again, thank you for contacting Lenovo.
    Sincerely,
    Lenovo Websales/CustServe"
    So this means I should call them and spend extra money for phone bill of international calls because of their fault of providing a basic feature that is to be expected from every single wireless card in the market. Should I believe that a guide over the phone is more efficient than a step-by-step solution or a link to an alternative driver? I'm getting kind of disappointed. At least they have understood (or copy-pasted) my problem, dutch comfort though.
    Any ideas? Anyone experienced the same problem and solved it? Is there an official (or even unofficial) driver for this device for Windows XP that allows me this basic feature (like b43 in Linux)?
    Thanks in advance,
    str4ngS

    Yes, I have posted this thread to different forums after I realized that Lenovo "customer care" is not likely to help me out and even wirelessforums.org members couldn't come up with any ideas for days, that's why. I have already written that helper applications like SMAC (or etherchange or macshift) don't work, because they do the same thing in the system as I change it in the driver panel, so they use the same method which simply does not work.
    Locked? Definitely not. If yes, why can I change the MAC of my adapter under Ubuntu Linux using b43 open-source driver if it's really locked? Or you mean it's locked from software, because Lenovo or Broadcom didn't want their users to change their MACs or they just forgot to release a fully-functional driver? Well, then I would like to have a driver in which it's not locked, because this is a basic feature of my adapter of which the hardware is capable.
    I have already contacted Broadcom, see their (automatically-generated) answer in my initial post, but I will try to do that again with more foresight.

  • Changing MAC Address

    Recently i have been trying to change my Router's MAC Address. I have a WRT54g v.3. I have done it before where i had unplugged the internet cable going from the wall to the modem. I saw the change on the 192.168.1.1 status page. And i noticed with a proxy and the new changed MAC address i was able to get into gaming servers i hadn't been able to before because my IP was banned.
    Now when i try to change my MAC address, it doesn't seem to change on the router stautus page like it did once before. I'm sure that it's possible to concel my identity of my old IP and get a new IP (through a proxy), many people do this for security reasons so i'm hoping linksys products can offer some kind of security by doing this.
    btw, sorry about the name, if it's possible can it be changed to Joe. Thanks guys.

    Your MAC is "stuck" to that router, you need to spoof it. Google it.

  • Safari will not load sites hosted on .Mac

    Ever since the most recent update, I have not been able to view any of my four websites hosted on .Mac. It doesn't hang with the spinning ball or crash, it just goes to a blank screen...no error warnings or anything. It does this on all four of our household Macs (they all have the latest update). I can pull up these sites perfectly on any other browser.
    Anybody else having this problem? Is there a way to revert to the older version of Safari or a fix?
    I've tried emptying the cache and sometimes that resolves it, but not for long...then it's right back to the same old same old and sometimes it doesn't help at all.
    Thanks for any and all input on this matter!

    Are you accessing the sites directly or through URLs that are being forwarded to your .mac sites? If it is the latter, it is probably the same problem being discussed in:

  • How to change mac address on mac

    i'm sry i'm not sure if this is the right section or not but yeah.... nyways does anyone know how to change mac address on a macbook?

    If you have not updated your OS you can use the following command.
    sudo ifconfig enX ether xx:xx:xx:xx:xx:xx
    You will need to replace the X with your network number and the xx:xx:xx:xx:xx:xx with the mac you want to have.
    Then run
    sudo ifconfig enX down
    sudo ifconfig enX up
    This change will last till your next reboot.
    cheers
    NOTE: This is not working in 10.5

  • How to change mac address on time capsule

    Hi there,
    How to change mac address on time capsule?

    There are routers that allow you to create/clone a mac address to whatever you like. Since many companies use the mac address to 'register' a unit connected to it's system, you usually just have to let them know you've changed your router and they will reset your system to accept connections from the new device.

  • Linksys WAP300N Change MAC address, console and etc

    Linksys WAP300N is very very suxx.
    Not simultaneous work of 2,4 and 5 Ghz, very buggy firmware and not reasonable price.
    I have 3 psc of this...
    About topic:
    Linksys WAP300N #1 updated to v1.0.03 - 5 Ghz stops working normally. Clients disconnect on heavy load.
    I want roll back to v1.0.00 but on official site no 1.0.00 firmware.
    OK. I am dump flash ic from normal, working WAP300N #2 with v1.0.00 and
    flash this dump to broken WAP300N #1 - 1.0.03. All is ok - AP is working, but MAC address from #2.
    I want access to bootloader for change MAC. I connect RS232toTTL cable to AP board serial port, but seems no normal
    serial it has. FFFFF.
    What can I do? If who has v1.0.00 firmware - please upload somewhere.
    p.s. Advise - if you buy this - do not update to v1.0.03. If not buy - DONT BUY!

    I don't have v1.0.00 firmware but I'd rather you properly isolate this by checking if you have experienced this to your other wireless devices. Because if the same scenario happened to all of your wireless devices connected to 5GHz, then it's best to change the 5 GHz network wireless channel. Preferred channels are 36, 40, 44 and 48 which are recommended to less likely suffer interference.  Also, make sure to take note each of the device's MAC address if you're trying to setup wireless MAC filter and do it manually. I normally use this link when I'm setting up wireless MAC filtering.

  • Changed Macs and want to download all tracks

    I changed Macs and want to download all my music from the cloud because streaming it is just hopeless.
    I can't find a simple way to do that. Most people suggest selecting all, right clicking and selecting 'Download' but when I do that, 'Download' is not an option offered in the menu.
    It's prolly something simple and obvious but I can't find it - anyone point me in the right direction?
    For a flagship product, iTunes sure ain't simple...!
    PS Using latest release of iTunes

    Downloading from the cloud is not really the most efficient or efficacious way to transfer your personal data to a new computer. These Apple KB articles will help you transfer the data more efficiently:
