I have a Linux virtualbox that I use for development. The stuff I'd like to share to the host operating system resides in /var/www. I tried setting up a samba share, but I can't seem to see my virtualbox on the network. Does anyone know how I'd go about doing this? I searched, but the only thing I've found is virtualbox's shared folders which isn't quite what I'm looking for.
By default VirtualBox networking defaults to an internal NAT implementation, which only allows the guest to access the network and not the other way around.
To access the guest from the host you have to use a different networking mode.
My preferred solution is host-only networking, because the guest appears as a proper networked-machine on the host, without being exposed to the public network.
Bridged networking would also do, but you'd have to secure the guest as if it was a separate machine and there may be networks where having two MAC addresses for a single physical PC is not advised or even allowed.
Why aren't shared folders what you are looking for, anyway?

I've a mac address which belongs to VMware virtual machine in my network(about 4k devices).
The virtual machine is used by VMware workstation on some host in my network.
All i got is a mac address of the virtual machine.
Is there any way to find it(by DOS/bash or similiar) without installing PowerCLI on each device or using arp table details(not allways the virtual machines appears there)?
thanks!
I very much doubt that this is possible since identifying host information from a guest could be a security concern. However, what you could do if using ”Workstation PRO” is to call the rest api from within the guest - if that sort of traffic is allowed.
I want to install Damn Vulnerable Web Application (DVWA) on VirtualBox, so I downloaded the DVWA.iso and I'm following this tutorial for its installation.
At step 9, they say to choose internal network, but I don't really understand why (is it a security problem if I don't choose this option?). Because if I select internal network after I've got an IP like 10.0.something and when I try to connect from my computer (not the VM) to 10.0.something/login.php that doesn't work. But if I select bridge networking, I've got an IP like 192.168.something and it works.
Could you explain me why is it important to choose internal network, and why that doesn't work when I choose this?
Internal network on VirtualBox creates a network between boxes on the same host . I can't see the next steps of the tutorial you linked but my guess is that it will ask you to install Kali (or similar distro) on another box on that same host. This is what most people do.
Setting 'internal network' allows the 2 machines to talk to each other without any contact with the outside.
It is considered a security measure because the DVWA is a vulnerable machine so some people think that you shouldn't be giving access to internet to it, but I guess it's more about 'best practice' than a real security risk because in most cases firewalls, routers and ISP will prevent outside attackers to connect directly to that machine in any case.
Anyways, if you are using another computer on the same network to connect to DVWA you should be ok in using a 'bridged' connection on VirtualBox (this it will give to the DVWA an IP sitting on the same network of the host and of your computer). In NAT mode VirtualBox acts like a router, it may still be a good solution for you but not sure if the box is reachable from other computers as I think VB settings may affect this case.
If you are using instead the Host as a penetration testing machine, 'host only' should be good to allow the host and the VM to talk.
Try to put both of the machines on the NAT so that you can ping onto the dvwa from wherever you're doing the hacking from! so essentially both of the machines should be on NAT setting if the they're both on a virtual machine.
Is it possible to create different Linux OS in Virtual Box and set different IP address and ping one host through the other?
I configured 2 Linux running on Virtual box with different IP address but when I ping the other one i get no answer.
Yes it's possible, what i can recommend you is to connect the virtual machines in bridge mode so each machine has a ip and is shared with your host machine
Yes is very possible.
There is several ways to achive this. One is use "Bridged Networkin".
You can see more hereVirtual Box - Network configuration
It should work as #Arthur85 said, set the vms into bridge mode. If it does not work, then check whether they are in the same subnet. If it does not work even in the same subnet, check the iptable rules.
I am new to embedded linux development.I have inherited a particular way of Embedded linux development from the previous developer.
I was just wondering if there is a more industry standard way of working.
This is how he was working,
There is an ARM embedded linux board which is not on the corporate network and has a fixed IP address of 192.168.0.52.I have a virtualbox based linux host which is connected directly to this linux board via an Ethernet cable.This host has an NFS shared with the target for running the cross compiled binaries.I have to set a fixed IP address for the host of 192.168.0.50.Then I can telnet with the target to run the compiled binaries on the NFS folder. Also as the VM host is not connected to the corporate network.I cannot use the company issued SVN for version control.So what I do is have a shared folder via virtual box between Windows and Linux host and I manually keep transferring the files which I have to commit/test.
What I would I ideally like, is both networks connected to the corporate network,so that I can update the OS,use version control.Is there way by which the VM on Windows access the corporate network and also be connected to the target.IT is not willing to give a static IP to the target.If we connect the target via DHCP what is the best way to discover it on the network.Also IT is concerned about the traffic it will generate.Can I use a switch to create a subnetwork,so that the target can have a fixed address?
Another question is they are open to a linux based host as well.Is a VM based linux any worse off than a Linux PC.The only problem I have been having are networking based issues,not really Virtualbox issues.But I am curious to know if there are any limitations at all.
In order to have the VM connected to the corporate network, you can setup the VM network adapter in bridge mode.
In order to discover the embedded device, you can use the arp command (for instance: arm -i eth0 -a).
If you have got two network interfaces you could also connect the remote device directly through this interface and setup a dhcp server in your VM.
Personally, I think that with the VM you can do everything that you need (cross-compiling the Kernel and bootloader and creating the remote File System). I have been using a VM for embedded linux development on a AT91SAM board without problems at all.
I'm setting up a linux server in a VM for my development.
Previously I've had PHP, MySQL etc etc all installed locally on my Mac. Apart from being a security risk, it's a drag to maintain and keep up to date, and there's a risk that an OS upgrade will wipe part of your setup out as the changes you make are fairly non-standard.
Having the entire server contained within a VM makes it easily upgradable and portable between machines. It means I can have the same configuration as the destination server and with shared folders even if the VM gets corrupted my work is safe on the host machine.
Previously with the local installation I was able to develop on convenient URLs like http://site.dev. I'd quite like to carry this over to the VM way of development but I'm struggling to figure out how, if it's possible at all.
Here's the problem:
In Bridged mode, the VM is part of the same network as the host. This is great but I can't choose a fixed IP address as I may be joining other networks and that address may be taken already. I'd like a consistent way of addressing my VM.
In NAT mode I can't directly address the VM without using port forwarding. I can use http://site.dev if I use the hosts file to forward that to localhost and then localhost:8080 forwards to the vm:80. The trouble is I have to access http://site.dev:8080 which is inconvenient for URL construction.
Does anyone know a way around this? I'm using ubuntu server and virtualbox.
Thanks!
The answer is to define a separate host-only network adapter and use that for host->guest communication.
You can do this by powering down the guest and adding the adapter in the VM settings. Once that's done you can boot the guest again and configure the new network interface however suits you best. I chose a fixed IP address in an unused range.
