On linux you can set up a virtual interface using
ifconfig eth0:0 ....
There's these questions:
How do you create a virtual network interface on Windows?
virtual network interface for windows
But they talk about vpn or loopback. VPN wont work in my situation as I'm trying to talk to a machine I don't have control over that sits on a hardwired subnet, which is not the one I get via dhcp. Loopback doesn't work as it doesn't actually talk to the physical device.
There's a hack on WinXP that lets you override dhcp by hacking the registry, but it was disabled in Win7 for security reasons.
For the record, the only solution we found at $WORK that actually solved the problem on Win7 (embedded) is a custom MUX (multiplexer) driver derived from source from Microsoft. That let us set up two different virtual adapters with the different configurations.
AddIPAddress doesn't let you add a static address to an adapter using DHCP in Win7 (it works in XP, but they disabled it in Vista).
AddIPAddress can be used to add a new IP address (and subnet mask) to an existing network adaptor. This should let you talk to a computer on a different subnet to the default.

I'm using a Windows Server 2019 server from Microsoft Azure. I have installed Hyper-V with the management tools and am now trying to setup a Ubuntu 14.04LTS VM inside of Hyper-V. I create a new External Switch however when setting up the Ubuntu instance there it tells me that there is an issue with the DHCP server. When I check my network connections for the newly created switch there is IPV4 connectivity, with packets being sent and received.
Things that I have tried:
-Ensured that inside of the Virtual Switch Manager that in my newly created virtual switch, the external network is selected as my main internet adapter. And that the "Allow management os to share this network adapter".
-Tried selecting "Internal Network"
-Inside of the ubuntu server, tried dchlient -r and dhclient eth0 to try to retrieve a new IP (For internal network this has worked, but without internet access, for external ip it hangs on the command dhclient eth0)
-In Network Connections I have tried bridging the two connections (out of desperation, "bricks" the vps causing me to not be able to rdp, must create a new azure vm)
-I have tried right clicking the main "ethernet" inside the Network Connections and allowing sharing options to other users.
Please help as I'm quite lost as to why the Ubuntu Guest is not connecting to the internet with the new network switch
The virtual switch connection types are very confusingly named, and sharing is somewhat flaky. I've had best results with the Internal Network. Most of the time it just works but there are certain situations when the NAT service breaks and you will have to restart some combination of the host and guest machines, possibly both -- I've not found a way to just restart the virtual switch service without restarting the host OS.
If you need to use the External Network type, be aware that your actual physical router will be in the mix, so you must make sure that it is properly configured, especially if you're doing MAC filtering on your router and the guest is not using the hardware MAC. This usually happens because of the virtualisation process itself, even if it's not something you've configured in the guest.
I have a setup with a few Linux devices and one windows device connected to a switch. I would like a way to tell the windows machine which IPs the Linux machines get when booting. I have tried to populate the arp table on the windows machine by pinging broadcast but I have not succeeded because windows doesn't reply to broadcast.
I have tried also nmap but that is not an option because it takes really long to scan (the net mask is 255.255.0.0)
You could set up a static IP and other network settings on all the Linux machines.
then on your Windows system edit your HOST file with the names and ip addresses.
This should bypass the need for a DHCP or DNS.
However other systems on the network will not be able to find your systems.
Regardless you still need to speak to the guys who administer the network to add your linux systems in.
It is rather impolite and/or against policy and somewhat bordering on illegal; to simply plug in your systems into the network not owned by yourself.
So if you have a right or need, the administrators will listen and should help you.
For sake of automation I need to be able to manually set the IP address of my Virtualbox guest (which is an OS X) to a fixed IP.
Can this be done using VBoxManage? I need to avoid the GUI.
Thanks
in your virtual machine setting, you can find networking adapters. You have some choice :
Network Address Translation (NAT): Used to share the host's IP address
If all you want is to browse the Web, download files and view e-mail inside the guest, then this default mode should be sufficient for you, and you can safely skip the rest of this section.
Bridged networking
This is for more advanced networking needs such as network simulations and running servers in a guest. When enabled, VirtualBox connects to one of your installed network cards and exchanges network packets directly, circumventing your host operating system's network stack.
Host-only networking
This can be used to create a network containing the host and a set of virtual machines, without the need for the host's physical network interface. Instead, a virtual network interface (similar to a loopback interface) is created on the host, providing connectivity among virtual machines and the host.
if you want specific IP for your virtual machine you can set in your guest vm ( ifconfig in linux & ipconfig in windows) and choose NAT in network adapter setting .

I'm currently working on a project involved in deploying Windows 7 (configured to our needs) to a lot of netbooks. For that I'm planning to use Acronis Snap Deploy and to push images through ethernet. I'm currently having issues with DHCP service though, because I'm using Windows 7 Ultimate on my PC (main). I tried to use programs which run DHCP services, but they all failed for some reason.
The thing is complicated with the fact, that my PC belongs to our corporate network with our our Domain and DHCP server - I connect to the network through WiFi.
I plan to use PCs Ethernet to create my own "private netbook network" :) I have to turn off my Wireless so that my PCs DHCP won't conflict with corporate's.
So my questions are:
1) If issue IS REALLY in DHCP programs, would I able to run Windows 2003 Server from Vmware Workstation, so that it would issue IP Addresses to the netbooks?
2) If you know better ways of deploying images to multiple PCs, can you advice me on that?
Thanks!
What network will netbooks be plugged in? You are talking about "private netbook network". Does it mean that all the netbooks are plugged in a network with only your PC and netbooks?
If so, you should install a DHCP server on your PC and enjoy. Netbooks get IP from your PC, no one knows about corporate network.
DHCP works by using broadcast. If your computer is connected to a corporate network that already uses DHCP, your new DHCP server may answer requests from other corporate PCs. You don't want that.
You need to make sure your DHCP server doesn't have a way to talk to the corporate network. You could put another network interface (like wifi you mentioned) in the PC, then make sure the DHCP server only hands out addresses on that non-corporate interface.
Using virtualization won't help unless the DHCP clients (the netbooks) are also virtual machines.
I am using a Macbook running 10.6. I am using VMware Fusion to run an Ubuntu Server minimal virtual machine. Ubuntu Server is running your basic LAMP stack.
I do my development in Mac OS. I have VMware share a directory from Mac OS to the Ubuntu Server. Ubuntu Server uses that directory for apache.
I access my server is Mac OS in firefox using the ip address of my virtual machine. This is a pain because I have to find out what the ip address is of my virtual machine each time I boot it up. I could set a static ip address but this causes problems if I move my Macbook from network to network.
Is there any configuration (NAT or Bridged or something) that would let me access my virtual machine from the Mac OS using localhost or something similar?
Thanks
NAT should be OK. Your VM is on a different subnet that way, you can give it the static IP you like, and it won't interfere with the (dynamic) IP on your real network.
What you are looking for is the host-only networking adapter as opposed to the NAT or bridged adapters. This creates a network interface on the virtual machine that only connects the actual host. It is perfectly safe to set an IP address for this interface that does not change, and there will be no tricky NAT getting in the way. It's a little network that only exists for communication between the real host and the virtual host. It's exact purpose is so you can do development like this. I use the same feature on VirtualBox all the time, but VMWare has it as well.
Now, with a host-only adapter you might be worried that your VM now has no access to the Internet. The answer is simple. Just make two adapters. eth0, eth1. Make one of them a bridged or NAT adapter for Internet access. Make the other one the host-only adapter for your development. Most modern Linux distros will automatically route accordingly. I know for a fact that Ubuntu does, because I do it all the time. Again, this is with VirtualBox. Your mileage may vary with VMWare, but I can't imagine it's that different.
I'm using Virtual Box and typing in the computer local address (for instance 192.168.1.100) instead of localhost did the trick.
Maybe I'm misunderstanding your question but why not just add an entry in your hosts file for the virtual machine? That way you can access it with some arbitrarily assigned name (like testmachine) instead of the IP.
This is the first tutorial I found through google: http://decoding.wordpress.com/2009/04/06/how-to-edit-the-hosts-file-in-mac-os-x-leopard/
This would work best if your VM has a static IP, BTW (either no DHCP or configure the DHCP server to give that MAC the same IP every time). That way you don't have to worry about changing the hosts entry every time the DHCP server gives the VM a different IP.
