configure networking between vm on virtualbox - virtualbox

I installed virtual box on my window 7 laptop, when i install new vm and install ubuntu os,now when i choose nat everything works fine when i am unable to configure host-only network on it .
and one more problem i am facing when i clone that machine and start it and change mac address from setting and start sometime no network configured on the machine .
i actually want to start two vm on virtual box ,both machine have 2 network adapter 1 for nat to communicate any where and one for host and local vms. if is possible or not if yes tell me configuration . i already tried solution from googling no luck still .

You can achieve that using only "Host-only Networking".
Setup is as follows:
Host:
At least 1 Host-only Network is present and configured, e.g.
- ip address is set to: 192.168.56.1
- dhcp server: enabled or disabled (works on both)
Note the name of the Host-only network, e.g. "vboxnet0". This will be used in the next steps.
Guest VM 1:
1. Set Adapter 1 (or any other adapters) to "Host-only Adapter".
2. Make sure Name is set to the name noted in the Host section above, e.g. "vboxnet0".
Guest VM 2 (same steps with Guest VM 1):
1. Set Adapter 1 (or any other adapters) to "Host-only Adapter".
2. Make sure Name is set to the name noted in the Host section above, e.g. "vboxnet0".
You can now start your VMs, and verify connectivity by pinging.
Note that if you are using Windows, you must disable firewall or just enable network sharing and discovery.

i found the solution , we can use bridge networking/host -only networking for establish communication channel among vms and host os
we can use nat for one n/w adapter and we choose either bridge networking or host -only on another adapter .
nat for connecting vm to internet
bridge networking/host -only -- communication among vms and host machine

1-if you have firewall switch it off
do a bridged network using you primary adapter.
use static IP on both
it will work just did and it worked fine for me.

Adding more details :
open vmware
click on file --> preference--> network--> Host-only Networks
Step 1 :Click on add and give a name lets say : Virtual Host-only Ethernet Adapter
select tab:
Adapter : 192.168.92.1 (we can select ip range own)
Ipv4 Network Mask: 255.255.255.0
without this it will also work ,For safe side configure dhcp too:
select tab --> DHCP Server
Server Address : 192.168.92.1
Server Mask: 255.255.255.0
Lower Address Bound : 192.168.92.2
Upper Address Bound : 192.168.92.200
VM Machine level configuration:
Adapter1 : enable this adapter for NAT
Adapter2 : Enable Network Adapter --> select this checkbox
Attached to : Host-only Adapter
Name: Virtual Host-only Ethernet Adapter( name get from Step 1)
on linux machine :
2nd network interface configuration, eth1
#append below line in networking conf : /etc/network/interfaces
auto eth1
iface eth1 inet dhcp
for statics:
#append below line in networking conf : /etc/network/interfaces
auto eth1
iface eth1 inet static
address 192.168.92.5
#gateway 192.168.92.1
netmask 255.255.255.0
broadcast 192.168.92.255
network 192.168.92.0

Editing TCP/IP Stack in Vmware ESXi 6

I've added another TCP/IP Stack to vmware 6 ESXi but I'm unable to edit it - or any other TCP/IP either, it's greyed out. Any ideas?
You need to edit it via CLI (esxcli).
First, list your netstack:
esxcli network ip netstack list
I guess you've added new VMkernel interface as well, so in that example you want to set new network info for vmk adapter:
esxcli network ip interface ipv4 set --interface-name=vmk1 --type=static --ipv4=192.1
68.100.222 --netmask=255.255.255.0 --gateway=192.168.100.1
Afterwards, VMK network looks like:
esxcli network ip interface ipv4 get
Name IPv4 Address IPv4 Netmask IPv4 Broadcast Address Type Gateway DHCP DNS
---- --------------- --------------- --------------- ------------ --------------- --------
vmk0 99.211.211.116 255.255.255.240 99.211.211.127 STATIC 99.211.211.113 false
vmk1 192.168.100.222 255.255.255.0 192.168.100.255 STATIC 192.168.100.1 false

Host and virtual machine cant ping each other

My hosts is Win 10, virtual machine is ubuntu on VMware play.
I fixed the VMnet1 IP as 192.168.32.1 and set static address 192.168.32.10 in /etc/network/interfaces on Ubuntu.
But I can't ping each other successfully.
Who can tell me the reason in detail?
Thanks in advance.
enter image description here
You should do next:
1. Check if Virtual machine's network use bridge mode (not NAT)
2. Use the seme network and subnet on Win10 net interface and Ubuntu (look at screen please http://prntscr.com/9u5b38)
at first sight there is not a problem.
you can provide for dhcp to assign ip address automatically for ubuntu and then you can restart network service.

using VMWare Player 5, how can I access a web server running in a VM via an external machine?

Win7 PC running Rails in an Ubuntu VM via VMWare Player. I'm working on a site and would like to show it to a friend who's outside my network.
I found this blog post, which got me very close: http://blog.fardad.com/2012/06/vmware-player-and-custom-nat-port-map.html
OK, so I have the VM that is using NAT. As I understand it, that means that the VM will appear to have the same IP address as the parent machine to outside traffic.
I went into NAT settings and added port forwarding:
Host Port: 8200 Type: UDP Virtual IP Address: 192.168.198.184:3000
OK so my understanding is that I should now be able to go to 192.168.1.1xx:8200 (the IP of my 'real' PC) and access the webserver running in the VM. But when I go to that address, I don't get anything. I can ping 192.168.198.184 (the VM) from the PC.
What I want to be able to do is go into my router and set up a port that will eventually forward into the VM.
It seems like I'm missing something very small but I don't know what that is. Help, please.
If anyone is curious how to get the Virtual Network Editor:
go to the vmware-directory and run in elevated cmd.exe-box
rundll32.exe vmnetui.dll VMNetUI_ShowStandalone
http://communities.vmware.com/message/2155960#2155960
Find the vmnetnat.conf file, usually located in
C:\ProgramData\VMware\vmnetnat.conf
or
C:\Users\Application Data\VMware\vmnetnat.conf
Edit vmnetnat, add similar line in the [incomingtcp] section
8200=192.168.198.184:3000
Restart VMware NAT Service.
Try using Bridged network option in vmware player instead of NAT. It replicates your physical network.
You can use an http proxy to do that, by doing that you don't need to expose your entire private network, check out this blog post for more information how to access docker containers from external devices

How to connect from a VMware guest machine to the server installed on a Windows 7 host machine?

How to connect from a VMware guest (virtual) machine to the server installed on the host (physical) machine? Things like typing "localhost" in the address bar of a browser in a guest machine don't work. My host machine's OS is Windows 7 64 bit with WMware Workstation installed on it, if it matters.
EDIT: The Bridged network connection in combination with referring to 192.168.0.10* from the guest machine did work (replace * with a digit starting from 0 until it works).
If you use "Bridged" Network Connection (see Virtual Machine Settings: Network Adapter), your VM will be given an IP address on the same LAN as your host machine. At that point, you can just HTTP to your host's IP address, eg. http://192.168.0.100
You can also do that with the other options, but with NAT and Host-only (if I recall correctly) your host machine will appear to your guest machine to have a different IP address than its real LAN address. So Bridged is the easiest and is likely your best bet, unless you have some specific needs.
First thing to do: Check that you have the network up and running. Try to ping the host system or any web site from the console of the guest OS, let's say ping www.google.com.
If you received any answers then please try writing the IP number of the host machine in the addressbar of the browser on the guest machine (NOT localhost :P). You should be able to see any web service running (Tip: Open the console of your windows 7 and type ipconfig, then find the ethernet adapter corresponding to VMWare and you'll find the IP number of your host system).
If you didn't received any answer at all when you did ping then check the network configuration of VMWare to use Bridged Connection --at least that's how it works for me.
Good luck!
In a guest machine, localhost refers to the virtual machine itself. Refer to the host just as you would from any other machine: by its IP address.
Note that it may be using a second "virtual" network adapter to communicate with the guest. Check the VMware to find out, and to find the second IP address.
Just use the same IP sub net for your VMware machine, if your windows system has ip address class C 192.168.0.10 So assign 192.168.0.120 IP to your Vmware machine and make sure that Firewall allow the traffic in vmware and also add the listener port manually in vm machine. go to system - administration- firwal-add port 1521.
Thanks

VMWare - Virtual operating system static IP address

What is the best way to have a virtual operating system have a static IP address in VMWware. I would like to keep the IP address static since it is a virtual server.
You can configure VMware DHCP server [which runs on host OS] to assign a fix IP address to a VM each time.
According to vmware docs, configuration is stored at the following locations:
Windows XP
C:\Documents and Settings\All Users\Application Data\VMware\vmnetdhcp.conf
Windows Vista or Windows 7
C:\ProgramData\VMware\vmnetdhcp.conf
Linux (host-only)
/etc/vmware/vmnet1/dhcp/dhcp.conf
Linux (NAT)
/etc/vmware/vmnet8/dhcp/dhcp.conf
VMWare Fusion for Mac (host-only)
/Library/Preferences/VMware Fusion/vmnet1/dhcpd.conf
VMWare Fusion for Mac (NAT)
/Library/Preferences/VMware Fusion/vmnet8/dhcpd.conf
Static IP and DNS name by MAC example:
host ubuntu {
hardware ethernet 00:0c:29:c0:2c:58;
fixed-address 192.168.118.3;
}
For more details on this please see this blog post.
Assuming you're not using NAT-based VMWare networking, the answer isn't any different for a virtual (guest) server than for a real one. You can:
Assign a static IP via whatever mechanism the guest operating system supports.
Configure the guest operating system to get its IP address from a DHCP server, and configure the DHCP server to return a static IP address for the VMWare instance's MAC address.
If you want the VM slice / VM machine (guest) to have a static IP, assign it to the VM slice. Then on the VM Server select "Bridged" for the network adapter settings. This tells VMWare to use what ever IP settings you have established on the guest.
This works on my machine
Follow these simple steps. Takes just 5 minutes.
1. Note the MAC of the VM
2. On the host machine open C:\ProgramData\VMware\vmnetdhcp.conf
a. Or C:\Documents and Settings\All Users\Application Data\VMware\vmnetdhcp.conf
b. These 2 files are auto synced or mirrored.
c. Open the editor in Administrator mode. Eg notepad++. Otherwise you will get access denied message
3. Add a new entry at bottom of the configuration file, right before the "# End" marker. MyGuestVM is any unique name. Example below
host sunilW2008Server {
hardware ethernet 00-0C-29-05-2B-A0;
fixed-address 192.168.63.222;
}
3. Shutdown the VM and close the Workstation
4. Re-start the VMWare DHCP and NAT services for changes to take effect (From services.msc)
Notes:
the below folders are at sync automatically.. change at one place and the same will be reflected on the other folder
C:\ProgramData\VMware
C:\Documents and Settings\All Users\Application Data\VMware
A simple workaround, configure the vmware dhcp server to use longer leases.
In the vmware config folder (on windows 7 -- C:\ProgramData\vmware) edit the file
vmnetdhcp.conf and change the values of default-lease-time and max-lease-time to
something bigger say 4 months (4mo*30days*24hours*60min*60sec = 10368000).
Then restart the vmware dhcp server. Then release and renew the lease on the guest.
Now your guest IP is static for next four months.
If you prefer to leave the VM host configuration as default, it is also possible to configure the guest machine to request a fixed address for dhcp. This will work even for the NAT network. In the case of Ubuntu and dhclient, this is achieved by the following block in dhclient.conf:
interface "eth0" {
send dhcp-requested-address 192.168.1.222;
}
