Sniffing the ethernet frames

Similar Questions

• Grouping of NETWORK cards causing the ESXi to retransmit ethernet frames received.

  I had an HP Proliant DL380 G5 ESXi 5.1.0 connected to a Cisco 3750 Switch stack.

  All by performing a tcpdump on a host without a report, I discovered that he was under the bombardment with ethernet frames for the MAC address of a computer virtual located on a host across the data center. After a few brief troubleshooting, I discovered that I was able to stop those erroneous frames by disabling NETWORK adapters on my VMWare host group.
  
  I believe that in my situation when ESXi is configured to use two network cards to all frames received on vmnic0 and retransmits them on vmnic1 and vice-vesa. I experienced these symptoms when ESXi is configured for failover with an active adapter and adapter mode standby and I also experienced the same symptoms in the following load balancing configuration.
  

  
  

  Symptoms: some time after activating the load balancing, all frames Ethernet for the MAC address of a virtual computer on the affected host are broadcast on each switch port in the entire data center.
  
  Steps to reproduce:
  (1) implementation below configuration.
  (2) unplug the ethernet cable connecting vmnic1 and switch1 port gi2/0/4
  (3) run the host 1.1.1.1 EI - n - q tcpdump on any machine physics linux in the data center (don't even have to be connected directly to 1).
  Confirm there is no packet seen with the IP address of 1.1.1.1 destination
  (4) plug the cable between vmnic1 and switch1 gi2/0/4 port ethernet
  (5) wait 60 to 120 seconds
  (6) watch a burst of frames ethernet with the destination MAC address of the VM (which owns 1.1.1.1) in the output of tcpdump

  hostname switch1

  I apologize for the delay in my response.

  Unplug physically 2 cable NETWORK card on the host and configuration mirrored port on the switchport to 1 NETWORK adapter of the host, I have been able to confirm that the host VMWare issues guides on NIC1 with a destination MAC address of one of its own VM.

  After carefully reviewing the captured data, I noticed that the destination frames wrong "02:bf:cb:50:a2:76" MAC address actually belonged to "Local Area Connection 1' one of my Windows 2003 Server WHAT VM installed on the suspected host.

  Dig a little deeper, I discovered that this virtual NETWORK card is presented to the operating system as
  Name: Local 1 network connection
  "Type: VMware Accelerated AMD PCNet adapt."
  MAC: 02-BF-CB-50-A2-76

  But the configuration of the virtual machine in vCentre is
  Name: Network adapter 1
  Type: Flexible
  MAC: 00: 0C: 29:fa:e8:83

  Note the different MAC addresses.

  Digging a little further I discovered that Windows 2003 server has configured on "Local 1 network connection" network load balancing and NLB is the cause of the altered MAC address.

  Rather than to investigate further I have just placed a load balancer linux before the server windows 2003 cluster and that you turn off NLB.

  But I suspect that there is still a fundamental problem in the Virtual Switch VMware with how he learns the MAC addresses of the virtual machine is using flexible vNIC. In particular, with a virtual machine that uses a form to override the MAC address such as that used by NLB.

• How to configure the Ethernet Apple TV connection

  With the new Apple TV Remote app how configure you a 3rd Gen Apple TV which is connected by ethernet? It seems that the Apple TV Remote app requires the Apple TV to be connected via WiFi.

  the ethernet port is located on the back

  your router must enable DHCP, if you are having problems with the wired connection, you can reset the router to the default settings. See the page of Web developers for information on this.

  the remote control does not connect over wi - fi, so it does not matter if the device is on a network, or not the remote control is concerned.

  Apple TV (3rd generation) - technical specifications

  If you can't fix this, go to settings, forget the current network of wi - fi and restart the device

  Settings > general > network > Wi - Fi

  
  

  Settings > general > restart

  
  

  If you are unable to connect with a wired connection, check the cable connection and verify that the cable works.

• When you export (share) a project, how to choose the thumbnail of the freeze frame which restores the clip?

  I just shared (exported) a project that is a simple take a clip for a friend who has downloaded on its website. The problem is that, when the video ends by playing on his site, he returned to a freeze frame that seems completely random and is not the image I want. How to choose the exact image that the video will return as "thumbnail by default?"

  Thank you

  Cannot set lla at the FCC. Many layout site Web apps will allow you to set the poster frame for the video files.

• What is a substitute for the migration assistant? I tried in vain for three hours to migrate files from a macbook pro to each other so that even if connected with the ethernet cable the computers never see each other.

  What is a substitute for the migration assistant? I tried in vain for three hours to migrate files from a macbook pro to each other so that even if connected with the ethernet cable the computers never see each other.

  You can connect otherwise?  USB or FireWire or love at first sight?  You can connect both machines and start the one you want to transfer to target disk mode.  If your other machine is up and running with an account on it and you just want to move files, you can simply drag and drop the FRO the machine mounted TDM, or you can use the migration wizard.

  Or, if the other machine still starts and runs, you can start both computers and connect to the same wifi network and share the hard drive like machines on the network.  Access them in the finder on the new machine files and drag-and - drop, or use the wizard migration, on wifi.

• MB Pro restarts randomly with the ethernet cable is plugged

  I recently bought a thunderbolt reduction - Ethernet [1] and it works very well. The problem is that when it is plugged in, my MacBook Pro (13', 2015, i5, 8 GB) gets very hot. This isn't a problem, but the next thing is really annoying.

  Whenever I'm not load, but the ethernet cable is connected, and MacBook goes into sleep mode, the system turns off instead. Thus, for example, when I don't have the power cable and if go for 5 minutes, the system automatically sets the mode 'sleep'. When I come back, it is turned off, and when I hit the power button, a black screen with the Apple logo and a text in several languages, saying that the system restarted because of a problem. After that, MacBook starts normally.

  The same phenomenon occurs:

  • When the power cable is not connected and I close the screen
  • When the power cable is not connected and I SLEEP manually the MacBook
  • When the screen is closed and I plug the power or the ethernet cable

  I use OS X 10.11.

• How to extend the network and using the Ethernet port to connect an older computer without wifi capability

• Satellite Pro L630-12: the Ethernet controller v v. WLAN network card

  Basic questions:
  My Satellite Pro L630-12F has (A) an Atheros AR8151 PCI - E Gigabit Ethernet Controller, and (B) Broadcom 802.11n Network Adapter.
  Toshiba continues regularly informing me that a Wireless Lan Driver update was released, which I need to install.

  First question: is Wireless LAN Ethernet controller driver or the network card?

  I have check the versions on my machine of both (A) and (B) with the PC diagnostic tool and find that (B) is the latest version (5.60.48.35) and (A) is a very old version (1.0.0.26). I download the latest version (9.2.0.316.0) of "Atheros Wireless LAN Adapter" for my machine from the Wireless LAN Driver download page (Windows 7 (64)) and run the file. But, everywhere I look, my machine continues to say that the version of (A) is (1.0.0.26).

  Second question: am I update the Ethernet Atheros controller when I download and run the Atheros Wireless LAN Adapter?
  If Yes, then why doesn't it show the latest version information?

  Sorry for the basic questions, but I found no explanations in various forums on the difference between 'ethernet controller', 'network card' and 'Wireless LAN' after searching several times. I'm afraid that Toshiba keeps informing me that I don't have the latest version of the wireless LAN driver despite my efforts to follow their instructions.

  > First question: is Wireless LAN Ethernet controller driver or the network card?

  Ethernet controller can be both; WLan and LAN in your case I guess that WLan is Ethernet controller, it would seem if the WLan driver is not installed

  Your laptop L630-12F seems to bear card Broadcom BCM94313 WLan and the driver can be found here:

  This is driver LAN!

• Satellite Pro R50 - B - not able to find the ethernet LAN driver

  I'm working on a windows 7 64-bit Image for the portable Satalite Pro R50 - builfing B.

  I can't locate the Ethernet adapter at all.
  I tried all the downloads of drivers on the official website, but nothing works.

  There is no unknown device in Device Manager and there is no other than the wifi network adapters those. Ethernet is enabled in the BIOS.

  The building had been tested on 8 different cell of the same model so not just a case of port defective. We plague equine laptops were build with Windows 8 and works very well.

  Any suggetions?

  All the drivers, but also the Realtek LAN driver (Win 7 32 bit 64 bit and Win 8.1) can be downloaded from the Toshiba UE driver page:
  http://www.Toshiba.EU/innovation/download_drivers_bios.jsp

  I think that the laptop was equipped with the Realtek module and the driver from the driver page should work.
  But you can also use the mini PCI database to find out more information on this module.

  Have you tried to install the driver in Device Manager?

• The WAN Port is communicating with the Ethernet switch?

  I have a Comcast gateway that the router is disabled in so it acts only as a modem. This is related to an Airport Extreme, which serves as my router via the WAN on the AE port. I created a different WAP with a Capsule temporal from the airport, located downstairs with an Ethernet cable from one of the Ethernet ports on the AE to the WAN on the TC port. I think it's what we call a 'roaming network.

  My question is, can I connect my switch Gigabit 8 ports in one of the Ethernet ports on the TC to complete connections wired to all devices connected on it, or should I first connect EI to the switch 8 ports and then connect the switch to the port WAN TC to complete my network "roaming"? In other words, plug it into the port WAN AE or TC still allows you to use other Ethernet ports as a switch?

  Thank you!

  can I plug my Gigabit 8 ports switch in one of the ports Ethernet on the TC to complete wired connections to all devices connected on it

  Yes, assuming that the TC has been configured to run in Bridge Mode, which would be normal.

  or should I first connect EI to the switch 8 ports and then connect the switch to the TC WAN port to complete my network "roaming"?

  It would be considered preferable to wiring, if it is convenient to do so.  For example, in the configuration of the wiring in the previous example just above... If there is a problem with the time Capsule, then all devices connected to the switch to the time Capsule would have a problem as well.

  If the switch is connected to the AirPort Extreme, and the TC is then connected to the switch... If the TC has a problem, the other devices connected to the switch of will not be affected.

• HP Pavilion g6-1310ea: can not find the ethernet controller driver

• HP Pavilion g6t - 1 d 00: cannot find the Ethernet drivers

  I have a HP Pavilion g6t - 1 d 00 Mobile (product #-A1J17AV;) Series # 5CG217015R) with Windows 7. The operating system has crashed so I reinstalled a fresh copy of Windows 7 (64-bit) on my computer.

  The HP support site is not all the drivers for the Ethernet wired network adater. The Device Manager has the Ethernet controller, PCI Device, network controller and peripheral other SM Bus controller listed under, and he says there is no driver installed for these devices.

  In addition, all the other drivers on the HP support site are for Windows 8, nothing for windows 7. I tried to install the wireless broadcom and intel drivers (I don't know which one I have), but they no longer work.

  Could you please tell me where I can get the correct drivers?

  Thank you.

  Neel

  Hello:

  Here are the drivers you need for the:

  SM Bus controller: Install first this driver and restart the PC.

  This package contains the driver and Intel Chipset Installation Utility for the notebook models and operating systems. This utility allows the operating system to show the correct name for the Intel hardware that is installed in the Microsoft Windows Device Manager.

  File name: sp55095.exe

  Ethernet controller:

  This package contains the Realtek driver local area network (LAN) that allows the NIC (NIC) Realtek chip in the notebook models that are running an operating system supported.

  File name: sp55040.exe

  PCI device:

  This package contains the driver that allows the Realtek card reader in laptop models running a supported operating system. The card reader allows users to read or write to removable storage cards supported, which are typically used in digital cameras, digital music players and cell phones.

  File name: sp55038.exe

  Since your computer laptop is a CTO model, there may be several different model wireless cards which might have been installed on your PC.

  Please view the ID of the hardware for the network controller (which is the wireless card needing a driver).

  To find the hardware ID, click on the network controller device in Device Manager.

  Then click on the Details tab in the upper part of the window network controller.

  Now you will see a drop-down list of property, and it will be set to the Description of the unit.

  On this list and select the item at the 2nd (hardware ID).

  After the first string of characters you see in the window.

  Also, here is the link to the page of the W7 driver for your laptop.  It has all the drivers and the software you need except for the controller driver smbus I have a template with similar equipment.

• Dynadock U3.0 - cannot use the Ethernet port after update 8.1 Win

  Hello world

  I use a u3.0 dock Dynadock with my Vaio PCS 13.
  I'm not able to use the Ethernet port on the Dynadock since I updated my Windows 8.1 device update 1.
  Before that everything worked well.

  I'm not able to re-install the drivers correctly (tried 7.6m0, 7.5m2). While the game driver tries to start, I get an error message, Setup is not able to put a bunch of registry (SYSTEM\CurrentControlSet\Services\DisplayLinkGA\D evice1) keys (up to 0). (Image 1)

  If I ignore these messages and do not install the driver, the Ethernet port will not installed in Device Manager. (Image 2)

  If I try to install the driver manually (DisplayLink network adapter NCM), I'll get an error message that a driver has been found but that access has been denied. (Image 3)
  I started the safe mode and could install the driver. But if I reboot in normal mode, the machine could not be started.

  I also tried to disable UAC and I am logged on as administrator 'real '.

  Please find the attached messaged (in German) error:

  Hey Buddy,

  Controller driver Ethernet can be both: WLAN or LAN card. All the drivers and tools can be downloaded from the official website of Toshiba:
  http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

  You have installed Windows 7 Ultimate, but may I ask why you haven t used the Toshiba with Windows 7 Home Premium recovery disc? On this disc are all the drivers and tools are installed because it s a picture of factory for you don t have stress with driver and installation tool.
