My host machine's running Ubuntu with Windows XP guest via Virtualbox.
My Ubuntu host have one serial port(/dev/ttyS0), and now I want to use hyperterminal inside XP guest to send & recieve data via serial port(COM0) to my Ubuntu host
On the Ubuntu host I use pyserial to read & write data to XP guest.
How to setup Virtualbox for this case?
Thanks!
I think you are using the same serial port on your host and guest OS's.
If yes, you can't.
Or you bind the guest OS serial port to the real serial port and use another serial port on your host (connected by a null modem cable), or you have to use sockets on the host. This socket is created by VirtualBox ( http://www.virtualbox.org/manual/ch03.html#serialports):
On a Mac, Linux or Solaris host, a local domain socket is used
instead. The socket filename must be chosen such that the user running
VirtualBox has sufficient privileges to create and write to it. The
/tmp directory is often a good candidate.
On Linux there are various tools which can connect to a local domain
socket or create one in server mode. The most flexible tool is socat
and is available as part of many distributions.
In this case, for on the Linux host, you won't be able to use PySerial.
But on the guest OS, PySerial will work fine, as to the guest OS the virtual serial port will look like a real one.

I am trying to make an IOT using nodemcu and a LED. I want to access the Ubuntu Server(which is installed in the virtual box) through some other network(outside my LAN). How can I do it? I read many articles online, but I am not able to figure it out. I tried port forwarding but it did not work.
I am not sure what I am doing wrong. Is there's a problem in the port forwarding, or I am following a wrong method.
I have installed Ubuntu Server 16.04 LTS on my laptop via VirtualBox. I have installed LAMP. Also, network set to bridged adapter, plus I have dynamic IP
As I logged in, I ran ifconfig. It gave me the inet address as 192.168.16.101
Did you set the VM network interface to be NAT or Bridged?
If it is NAT, then you are essentially double NATTed which means you will need to port forward from your router to the VM host and then you will need to port forward from the host to the VM as the IP assigned will be local to the host machine.
However, the easiest is to set the VM network interface to Bridged.
This will mean the VM will be able access your network directly as it should be on the same subnet as your laptop and appear as another device, which your router will be able to port forward to.
I currently have a virtual machine running on Windows. The VM is running Linux and has a virtual box network between the windows machine and the linux machine. The VM is running a application that I want to be able to connect to from the outside world.
To make this possible I tried port forwarding from the windows internet interface, to the windows virtualbox interface. Finally I created another port forward from the windows virtualbox interface to the Virtual machine interface.
netsh interface portproxy add v4tov4 listenport=5000 listenaddress=10.11.65.103 connectport=7890 connectaddress=192.168.56.1
netsh interface portproxy add v4tov4 listenport=7890 listenaddress=192.168.56.1 connectport=5000 connectaddress=192.168.56.101
So if I connect to the 10.11.65.103:5000 on the Windows Machine it will be the same thing as connecting to 192.168.56.101:5000 of the VM.
[Win Internet Intf] [Win VM Intf] [VM intf]
10.11.65.103:5000<----->192.168.56.1:7890 <------> 192.168.56.101:5000
Unfortunately, this is not working for me... Can someone tell me why? Am I using port forwarding correctly?
If you use a bridged network adapter your Linux machine should pick up an IP off the host network (if you have DHCP enabled on the network, or set a static IP on the linux box). Then you should then not need the port forwarding.
If you cant use that approach and are using a NAT adapter (which it looks like you are), then you will need to enable port forwarding within VB. The details are in section 6.3 of the VB Help with this in place you should only then need the first port forward, VB will be doing the second.
Dont forget to make sure the relevant firwalls on the Windows and Linux machines are open.
I want to set up an exported VM on an Ubuntu Server using VirtualBox on headless mode.
I have the VM up and running and bridged with the ethernet interface of the host (em1), so the dhcp of the host should now assign an IP to the VM if I'm not mistaken.
Is there a way to check if this is working and if yes to get the VM's IP?
Since this is on headless mode so without GUI, the only way to login to the VM is through ssh and for that I need the IP..
welthenwel,
you can do this with VBoxManage.
from a shell, just type:
VBoxManage guestproperty enumerate VM_NAME --pattern */IP
and you will get as response something like in the below image.
now, ignore the fact that I run this cmd from a Windows host, because its behaves exactly the same from inside a linux host
I'm not very familiar with VirtualBox. Bridged with VMWare Workstation meant the IP is given by your default DHCP server, which means you could look up the assigned IP address there (e.g. your router - if you have access to it).
Another option would be a ping sweep of your network segment as I believe Ubuntu doesn't drop ICMP requests.
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 have Oracle Virtual Box installed on Ubuntu 10.10. I want to gain access to my script that runs on local. My virtual operating system connects via network and takes an ip address, but how would someone access my script that runs on local? Which ip address can be used?
If you use bridged network and your VM is on Ubuntu 10.10. One easy way is to use ssh. By default ssh is installed and configured in Ubuntu 10.10. You can connect to it by :
ssh you_virtual_machine_ip
ssh is a powerful tool and your can run scripts when connected to the host.
If you are in Windows System, Putty is a great tool of ssh client.
type this from your host os
and you have to open the port 80 from guest OS (Ubuntu)
