First I must say that I have no idea what kind of problem it is (Ubuntu/Windows/vmware/secureW2), so I hope anyone can select the necessary information from this mess.
I am running an Ubuntu 15.04 guest on a Windows 10 host using the vmware Virtual Machine. The Ubuntu internet icon in the right hand corner claims that it has a (wired) connection, yet I can't browse or ping google. Windows 10 is successfully connected by wi-fi, vmware uses a bridged connection (automatic) and my router enables DHCP. I can successfully ping my router from within the VM (at least, I assume 192.168.1.1 still refers to my actual router, and not some virtual router). In windows I can see two network adapters running (VMnet1 and VMnet8), both of which say they're enabled but have no internet access. I tried installing the bridge protocol in them, I tried using NAT instead of a bridge, but all to no avail. I was still connected just a few days ago when I was at school, which makes me think SecureW2 (a program responsible for connecting me to the school wi-fi) could also be involved somehow.
Everyone thanks in advance!
Turns out it was DNS related, caused by Ubuntu and SecureW2. The /etc/resolv.conf file was set up specifically for the LAN at school, for which I blame SecureW2. I "solved" it by adding my router IP to (the top of) the name server list, though I know this is only a practical solution.

I've run into a problem adding IP's to an SME server VM.
Determining if ip address xxx.xxx.xxx.xx is already in use for device eth3...
Error, some other host(mac address) aleady uses address xxx.xxx.xxx.xx.
Now, of course, I started looking at other servers hosted in Proxmox and outside of it as well, finding no other device using the IP addresses in question.
You could ping one of the addresses, but not the other.
More precisely I could ping the local address, but not the public one.
I realised that the device using the IP's is actually Proxmox itself. When I disabled the interfaces in the host (ifdown vmbr6) I could assign the address to the server in question after that.
The IP's are configured like this in the Proxmox network tab.
vmbr6 Linux Bridge enp5s0f0 xxx.xxx.xxx.xx 255.255.255.0
Now I might add that the SME server is being migrated using this guide:
https://www.caretech.io/2017/10/17/migrating-virtualbox-vdi-to-proxmox-ve-5/
Though I don't think it's related to the networking issue.
So steps that I've taken to try and fix the issue are:
Rebooted the SME server
Restarted the networking service on the SME server
Rebooted Proxmox
Removed network interfaces from the SME server
Changed the interface model from VirtIO to IntelE1000
Tried changing the MAC addresses
I've been battling this issue for 2 days and any and all help would be appreciated. Kind of in a hurry to migrate our services from VirtualBox to Proxmox.
Thank you.
I am using OSX Mavericks and VMWare Fusion v6.0.2.
I am running two Virtual machines, one Windows 7 Pro, and the other Debian Sid.
I do not wish to use NAT networking through the Host, I prefer to have the VMs sitting directly on the network, but I am having a problem getting the bridged networking functionality of VMWare Fusion working correctly. I have set the VMWare Network preferences page to Bridge the VMs to the Mac internal WiFi adapter.
Both VMs can ping the router, and they both get valid DHCP assigned IP addresses for the LAN. They can both connect to the Internet over the network bridge and browse and download files.
My problem is when I wish to communicate between the VM->Host, Host->VM, or VM->VM over other ports. For example if I try to SSH from OSX Host to the Debian VM, the request times out. The Windows 7 VM has a SQL Server running on it, but I cannot connect to it from the OSX host, or from the Debian VM. The Debian VM has a xsp4 web-server running on port 8080, but neither the OSX host nor the Debian VM can access it.
I can ping from Host->VM, VM->Host, and VM->VM with no issue, they can all see each other on the network, and the OSX host is sharing network folders to the Windows 7 VM without a hitch. It seems like it is allowing some communication, such as DHCP requests, Ping requests, Windows Network Shares, and Web Browsing, but is not allowing anything else.
I have turned off the Windows Firewall, OSX Mavericks firewall is turned off, and the Debian VM doesn't have selinux or iptables firewalls installed.
I have found several similar question threads while researching this problem, but a lot of them are for much older versions of VMWare Fusion, or are for VMWare Workstation which has different network preferences.
I can get these scenarios working to a degree if I switch VMWare's network settings to use NAT instead of bridging, but that messes up the IP addresses of the VMs, I want to keep them on the same network.
For what its worth, I did eventually come up with an answer for this.
There are two different versions of VMWare Fusion 6.x, Standard and Professional.
I was using the Standard version.
I changed the licence for a Professional licence, which allows you to add new network configurations in VMWare Preferences (and other cool things like that).
I added a new network with the default options, then assigned all of my VMs to that new network interface. I also turned on Promiscious mode in settings, but that might not have changed anything.
I then rebooted the VMs, set them up correctly to work on their new IP addresses, and Lo and Behold, I was able to establish connections between VM->Host and VM->VM. Exactly what I wanted.
I realize that this post is several years old, but since I had such a hard time with an issue similar to this, I wanted to post my answer as well, though I am not positive it really solved my issue. No problems still.
My setup:
MacBook Pro (Retina, 15-inch, Mid 2015)
OS X El Capitan
My problem:
In order to allow me to clone my private school git repository using ssh keys, I have to run a bridged network connection for my Windows 10 Eduction VM using VMWare Fusion.
What I've Tried:
http://www.kapilarya.com/windows-sockets-registry-entries-required-for-network-connectivity-is-missing
https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1016466
And several other blog posts and forum replies, all attempting to do somewhat the same thing.
Answer:
After numerous attempts to reset just about everything you could, I took a step back and brainstormed. Then I thought, if my host machine (Macbook Pro) could connect wirelessly to the internet, this bridged connection should still work. I checked the Network Adapter's MAC Assigned to the VM's Network Adaptor and it was different from my host computer's wifi address (MAC Address). I then entered my host machine's wifi network address (MAC Address) in as the effective MAC Address for the Windows VM Network Adaptor and..voila, internet.
I'm running Apache etc (actually MAMP at the moment, but soon to be replaced by individual Apache, PHP, MySQL...) on my Mac, for testing my websites locally/offline.
I want to be able to test all my local sites (domains *.dev) from any and all of the following, without having to update the hots file on each device (some of which, such as un-rooted phones, don't even allow editing of the hosts file):
Obviously, my Mac itself...
Any device on any local network to which my mac is connected (My Mac doesn't necessarily always have the same IP address)
Any virtual machine running on my Mac (in Parallels) – primarily, various versions of Windows (my Mac does always have the same IP address on Parallels Shared Networking)
Now, I read that dnsmasq may be able to help, and have installed it on my Mac using Homebrew. I set it up to start on startup, and my dnsmasq.conf reads as follows:
address=/.dev/127.0.0.1
This has the effect of allowing any domain *.dev to work on my Mac itself, which is a start.
Next I tried to make it work in a Parallels VM by setting the DNS server to be the local IP address of my Mac. However, this doesn't work – because dnsmasq returns 127.0.0.1 as the IP for any lookup for *.dev, but of course this makes the VM look for the site on the VM itself, rather than on my Mac... which obviously doesn't work.
So I'm a bit stumped. Can anyone give me any tips? Is there a way to set up dnsmasq to do what I want, or should I be looking at another method?
Thanks!
I don't have any experience with Parallels but with Virtualbox you can set up a bridged network connection. I presume Parallels has something similar. This will set up an internal network (e.g. on 192.168.1.*) and you can probably assign fixed IP addresses to that. Like this you can give the Mac a fixed IP address which you can also use in your dnsmasq configuration - but you might want to have two TLDs for this so that .dev can keep pointing to 127.0.0.1 while .devel points to 192.168.1.xx.
I am using VMWare Player 3.1.0 on Host OS Windows 7 Professional 64-bit. My guest is is SUSE Linux ES 10. My guest OS (SUSE) runs JBoss App Server which I access from host using HTTP. I used a "Bridged" connection to set up all this.
My problem:
When I am connected to network on the Host (using wired network adapter) I can connect to the http server on the Guest OS and browse the application. However, when I am disconnected from the network on Host (unplugged the wire), I cannot access to the guest OS app server and browse the application. I use the guest OS ifconfig command to find out ip address of the guest OS. This ip address does not change whether connected or disconnected. I have even tried using Wireless Data card, but that does not work either.
I have tried "NAT" as well as "Host Only" connection and rebooted the guest but it does not work either. I think for some reason the guest OS can only recognize the physical network card (which is disconnected).
I need to run this machine (my laptop) independently of the network because I use this for demo and need to be able to connect from my host OS to Guest OS.
I am not sure I understand exactly what you are trying to do, but I do know setting up a working NAT configuration will offer you the most flexibility.
Click the networking icon and select settings, Select NAT.
Follow these steps on your Unix OS
cd /etc/sysconfig/network-scripts
Make a backup of your ethernet adapter configuration
cp ifcfg-eth0 ifcfg-eth0.bak
Next modify the settings to look like the following:
DEVICE="eth0"
BOOTPROTO="dhcp"
HWADDR="What ever was here on your system"br/>
NM_CONTROLLED="yes"
ONBOOT="yes"
Save your changes
Restart your network adapters
/etc/init.d/network restart
Try nslookup www.google.com
You should now be able to connect back and forth from your Windows Host and Linux guest.

-p.s. I had screenshots, but I do not have the 10 points yet to post images.
I figured that the solution is to restart the VM after making the changes to the NetWork setting on the VMWare. I selected Network for the VM as "Host Only" shutdown the VM and started it again. After that I was able to do what I wanted to do (i.e. browse the web application on guest from the browser in the host machine) without connecting the host to the network.
So key to the solution in my case was to make the network changes and restart the VM.
Any comments suggestions welcome...
I'm a complete newbie to VMWare and troubleshooting networking issues.
I'm running the buildix app through VMWare Player on my laptop. Things work fine when I'm connected to my home wireless network.
However, when I'm not connected to a network, my wireless card is turned off (eg., to save power) or when I'm connected to another wireless network, the Buildix appliance / VMWare player fails to get an ip address.
I only want the appliance to be able to communicate with my laptop.
I've tried this in all 3 networking modes : Host-Only (which is what I believe I want), NAT and Bridged, all with no success.
I've also taken a look at the settings by running vmnetcfg.exe in the VMWare Player install dir, but can't see anything obvious here.
Can someone please assist?
Regards
Marty
Host-Only mode is probably the way to go in your case. The problem is NAT and Bridged mode are relying on some third-party DHCP server to provide an IP address, and that server is not available when you are running disconnected.
VMware Workstation (not sure about Player) provides a built-in DHCP server if your machine is configured onto the right virtual network switch. You can also adjust which virtual switch has the DHCP server, what IP addresses it gives out, etc.
If Player does not support this feature, you may be forced into setting the IP address of the virtual machine manually. This is dependent on what OS you are running.
