So if there are two hosts, both with the same MAC address, then the switch will update it's MAC table every time it receives a frame from either host. The reachability of either host will flap on and off and be inconsistent. Find Mac Address in Ubuntu with Command Line. Ubuntu is known for its simple-to-use interface and its Terminal feature. In this method, we are going to utilize our Terminal to find out more about our MAC’s IP address. The steps are below. Press Ctrl+Alt+T to open your Terminal. Wait for it to boot up.

I'm guessing the answer is no. But if restoring a full VM back into esxi or vsphere - is there a way to end up with the same Mac Address on the virtual ethernet card? I am asking because we have one application that runs on a server, where the product key is actually tied into specific settings on the NIC.

Never heard of this before and it seems stupid to me. Nic got deleted in some troubleshooting and re-added, but as a new nic with a new mac address. Now we are down until Monday when Tech support is available. TBH, I didn't look into Gabrielle's link to see it involved adjusting with the vmx files. I think there is an easier way. You can change the mac address via the vSphere client if you stop the VM and then do. 1) Right click on the VM then select Edit Settings.

2) Select the Hardware tab 3) Select the network adapter in question. 4) On the right panel there is mac address, select the manual radio button and then enter the new mac address there. 5) Restart the VM [Edit] @britv8, sorry I must have been editing my post and didn't see you supplied the same info first.

To do this we open terminal (Use Search) and type: cd /var/db/receipts/ Then you can type: “ls” (minus the quotations) to see the files in the list, but you don’t need to.

[/Edit] There are some issues with this method where you've moved a VM from an earlier host where it auto-ed the MAC address in one range whereas ESXi 5.1 + uses a different range to auto allocate. It then won't let you change the MAC Address manually to the previous range.

On occasion you will need to edit the hosts file on your machine. Sometimes because of an attack or prank, and others so that you can simply and freely control access to websites and network traffic. Microsoft kept the hosts file alive in Windows networking which is why it varies very little whether used in Windows, OS X or Linux.

The syntax stays mostly the same across all platforms. Most hosts files will have several entries for loopback. We can use that for the basic example for the typical syntax. The first part will be the location to redirect the address to, the second part will be the address that you will want to redirect, and the third part is the comment. They can be separated by a space, but for ease of reading are typically separated by one or two tabs. 127.0.0.1 localhosts #loopback Now let’s look at accessing the hosts files in the different operating systems Windows 8 or 8.1 or 10 Unfortunately Windows 8 or 10 makes it annoying to open apps as administrator — but it’s not too difficult. Just search for Notepad, then right-click on Notepad in the search results list, and choose to run it as administrator.

Step 1 – If you’re using Windows 10 this will be on the Start Menu. If you’re using Windows 10, it’ll look more like this: Step 2 – Once you’ve done so, open up the following file using the File -> Open feature. C: windows system32 drivers etc hosts Step 3 – Then you can edit as normal. Windows 7 Step 1 – To access the hosts file in Windows 7 you can use the following command in the Run Line to open notepad and the file. Notepad c: windows system32 drivers etc hosts Step 2 – Once notepad is open you can edit the file.
