Debian Configuration :: VirtualBox: Host-only Networking: Static IP Guest Addresses?

Jun 6, 2011

Debian Testing host, Winduhs XP guest. Winduhs is not allowed to directly access The Internets, and I am not setting up bridging as that makes it possible for the guest to mount layer 2 attacks on the LAN. I need for the guest to tunnel through the host without being able to see anything on the host, so it can then get access to The Internets, while being protected by iptables (Shorewall).

Used to be with VMware I had host-only set and the guest in a different class c (192.168.2.1) from the host (192.168.1.1) I turned on ipforwarding, set Shorewall rules, and it all worked. Now I have everything set with VirtualBox, and it does not work. Guest can ping its interface but not host. Host can ping vboxnet0. Host is supposed to masquerade guest's 192.168.2.1 through to the default out at 192.168.1.1, but it's not. I think a clue is in routing, but I don't know what's wrong.

Ubuntu Networking :: Unable To Reach Guest OS In VirtualBox From OSX Host

May 18, 2011

Recently I've been unable to load web pages, hosted on my Ubuntu Guest in Apache, from my OSX Host. In fact, I can no longer even ping the Guest OS from the Host. In the past, when I did ifconfig on the Guest, I got an IP of 10.0.1.n. Now I'm getting 10.0.2.15--the default NAT Address. The thing is, I didn't change any settings recently. What I did do is run software update for OSX, Ubuntu, and updated VirtBox.

Current Versions:

VirtBox 4.0.8 r71778
Host: OSX 10.6.7
Guest: Ubuntu 11.04

why I can no longer access my Guest OS from my Host? I spent hours on this last night, to no avail. What would cause the Guest IP to change from 10.0.1.n to 10.0.2.15? As I say, I manually made no config changes.

CentOS 5 Networking :: Multiple Static ISP IP Addresses / Servers Configuration

Mar 31, 2011

I have a CentOS5 server with dual ethernet adapters + Webmin installed as my Router / Firewall / DHCP server working successfully with 1 static IP from my ISP. I also have 7 additional static IP addresses from my ISP needing to configure to individual servers inside my network. I have configured the additional virtual interfaces, but am lost on how to route data specifically from additional ISP address to specific internal network address.

Below is my desired configuration.
98.173.159.xx1 = eth0 physical interface ==> eth1 192.168.1.1
98.173.159.xx2 = eth0:1 virtual interface ==> 192.168.1.10 ==> CentOS Server 2
98.173.159.xx3 = eth0:2 virtual interface ==> 192.168.1.20 ==> CentOS Server 3
98.173.159.xx4 = eth0:3 virtual interface ==> 192.168.1.30 ==> CentOS Server 4
98.173.159.xx5 = eth0:4 virtual interface ==> 192.168.1.40 ==> Mac OS X Server 1
98.173.159.xx6 = eth0:5 virtual interface ==> 192.168.1.50 ==> Mac OS X Server 1
98.173.159.xx7 = eth0:6 virtual interface ==> 192.168.1.60 ==> Network Attached Storage Server 1
98.173.159.xx8 = eth0:7 virtual interface ==> 192.168.1.70 ==> Windows 2008 Server 1

Fedora :: VirtualBox Ping From Guest To Host?

Dec 9, 2009

I have VirtualBox v3.1.0 r55467 running on f12 2.6.31.6-162.fc12.i686. The guest is Windows XP SP3. I need to enable bridged mode for the virtual network interface on the guest. Everytime I enable bridge mode the following error occurs.

Quote:

Failed to start the virtual machine Windows XP. Failed to open/create the internal network 'HostInterfaceNetworking-wlan0' (VERR_SUPDRV_COMPONENT_NOT_FOUND). One of the kernel modules was not successfully loaded. Make sure that no kernel modules from an older version of VirtualBox exist. Then try to recompile and reload the kernel modules by executing '/etc/init.d/vboxdrv setup' as root (VERR_SUPDRV_COMPONENT_NOT_FOUND). When I run '/etc/init.d/vboxdrv setup' i get the following compilation error:

Quote:

Fedora Installation :: F12 As A Guest On XP Pro Host Using VirtualBox?

Jan 3, 2010

I have tried a few times already the following procedures: start a new installation (each time, I create a new VBox VM) with the Fedora 12 DVD iso attached to the DVD drive of the VM. I select the default setting, like US english, US keyboard, local time (GMT +8), standard installation ... etc). The installation process had been smooth to the screen the system asking for a reboot after installing something like 1100+ packages. Then I click the reboot button offered. The VM restarted but each and every time, it came up with the following error message:

Booting from local disk...
FATAL: INT18: BOOT FAILURE

There was no other error message durint the installation process. It would be very much appreciated if some one can tell me what went wrong and how to solve it. I believe even I try again the same way, it will end up with same result. Is it a software or hardware problem? In case software problem, is it Fedora or VirtualBox?

Slackware :: 13 Guest Additions For Virtualbox On Xp Host?

Jan 26, 2010

pretty comfortable at the command line and in kde. found 2 'supplementary kernel drivers' for virtualbox at slackbuild (thank you heinz!). followed the how-to at slackbuild and built and installed both packages, but additions weren't working. (i thought they were standalone) noticed the 'supplemental' in their description, and so installed the guest additions for linux from vbox site. additions still not working. at this point i start restarting my slackware vm, and redoing everything in various sequences. finally, additions work! but i'm not sure why! critical pieces and sequence for getting guest additions working once i have slackware installed?

OpenSUSE :: Access Web Server On VirtualBox Guest From Host OS

Sep 4, 2010

I used to be able to access the web server I had running on my guest OS in Virtual Box from my host OS. I also had it set to the network settings of "Host Only Adapter". Then I needed to access the internet directly on the gues OS, so I changed my settings on the guest OS to "NAT" (in virtual box), and in /etc/network/interfaces, I removed the loopback stuff and the static IP I'd put in. Now no matter what I do, I cannot get it back to being accessible from the host os! I even did a completely NEW install of Ubuntu guest OS in Virtual box Guest OS: Ubuntu 10.04 Desktop Host OS: OpenSUSE 11.3 VirtualBox: 3.2.6

OpenSUSE :: Virtualbox Where Host Can See Webserver From Guest And Reach Internet?

I have set up my guest OS in VirtualBox so that it has a static ip and is using a bridged adapter. As a result, I can see the webserver that's hosted in guest from my host OS's web browser. However, for some reason my current setup does not allow my guest to reach the internet. What settings do I need to enable both?

Slackware :: VirtualBox Guest On Win7 Host - Folder Sharing?

Jul 13, 2010

I have a Win7 laptop with the latest version of VirtualBox installed. It's a dual core proc with ram to spare. So, I installed Slack64-13.1 and it rocks! I'm really impressed that Slack is running at what appears to be native speed, but in virtual machine. Hardware response is normal, WIFI and LAN are both working great for my normal tasks.So, I downloaded a few much needed patches, and new ISO image for one of my old desktop PCs. Now, my problem is I can't connect my USB cdwriter to my virtual slackware or share folders in the Win7 install with the virtual slackware. I read a few of tutorials on the Oracle VBox website, and several of the ones here on LQ, and none of them seem to solve my problems.

General :: Using Samba To Share A Folder From A Guest With A Windows Host In VirtualBox

Mar 15, 2011

I would like to share a folder from a Linux Guest with a Windows host (with read and write access if possible) in VirtualBox. I read in these two links: here and here that it's possible to do this using Samba, but I am a little bit lost and need more information on how to proceed.

So far, I managed to set up two network adapters (one NAT and one host-only) and to install Samba on the Linux guest, but I have the following questions now: What do I need to type in samba.conf to share a folder from the Linux guest? (the tutorial provided in one of the links above only explains how to share home directories) Are there any Samba commands that I need to run on the guest to enable sharing? How do I make sure that these folders are only available to the host OS and not on the Internet? Once the Linux guest is setup, how do I access each of the individual shared folders from the Windows host? I read that I need to mount a drive on Windows to do this, but do I use Samba logins, or Linux logins, also do I use localhost? or do I need to set up an IP for this?

Ubuntu Installation :: 10.04 Guest In VirtualBox On Win7 Broken Host-only Adapter?

Jun 5, 2011

Setup:

1. Microsoft Windows 7 64-bit Professional HOST Operating System
2. Oracle VirtualBox 4.0.6r71416 on top of Windows 7
3. Ubuntu 10.04 Lucid Lynx 32-bit GUEST Operating System in VirtualBox

I successfully installed the above configuration on May 15, 2011. I had some difficulty getting the Host-Only VirtualBox Adapter to work. I was forced to make a subtle change to the Windows Registry in order to get the Adapter to work correctly. I was successful. I used the Debian Update Manager to update my installation of Ubuntu. Nothing changed on the Windows 7 side. Now, Windows 7 says that the Host-only adapter is enabled, but I don't have a connection to the Ubuntu OS. I can't use PuTTY or WinSCP. When I invoke ipconfig on the Windows side, 192.168.56.101 is the IPv4 address. When I invoke ifconfig on the Ubuntu side, there isn't anything.

Ubuntu :: VirtualBox Guest Faster Than Ubuntu Host?

Dec 19, 2010

I've recently installed Ubuntu 10.10 64 bit (say host H). I also installed Ubuntu inside VirtualBox on H using the same image (say Guest G). I'm working on a fairly large java project. I've installed the same version of jdk (sun-java-6) on both H & G. To compile my project - it takes ~3 mins 10 secs (consistently) on H, whereas it only takes ~1 min 5 seconds on G . The full build (compile + tests) takes ~29 mins on H, whereas it takes only ~7 mins on G. Tests do a lot of writes to mongodb. This is very puzzling. I think it has something to do with fsync disk io etc. But I'm not proficient enough to dig further. Maybe it has something to do with partition sizes of H, G?

Debian :: VirtualBox Guest-only Internet Access

Aug 12, 2014

Is it at all possible to disable internet access for the Debian host while providing internet access to the VirtualBox guest(s)?

I plan to only hook up the host to the internet for updates, upgrades and installations, although if I can, then I will make a Debian guest to test everything out and download the files from there and install everything on the host without even a single host connection point.

Is this the indomitable approach to intercommunication security? If not, then what haven't I thought of yet?

Networking :: Iptables Configuration On Debian Dmz Host?

Jul 6, 2010

I am trying to set up a DMZ host - that is, one multifunctional PC between the WAN and the LAN. I've started with a basic router, and expanding upon that as the need arises. I am currently trying to gain access (from the WAN) to a website hosted on one of the servers in the LAN, but I am having trouble accessing the host from the WAN; I think my iptables configuration may be too restrictive. On the DMZ host, I'm using Debian (Etch). I have setup dhcp3-server, a script to configure iptables and pound (reverse-proxy). The (virtual) machine has 4 network cards: eth0, eth1, eth2, eth3; eth0 is the WAN, eth1 through eth3 serve 3 different virtual LANs.

All machines in the LAN (except one windows 2008 server - I might want to address that problem later) get their IP adresses correctly via dhcp from the DMZ host. All machines on the LAN can access the internet (including the 2008 server if I configure it manually) as they should. If I access http://localhost on the DMZ host, pound reports "The service is not available. Please try again later." - as it should.

I can ping the DMZ host from the WAN on 10.0.0.79 However, if I try to access the DMZ host from the WAN (http://10.0.0.79) I get "Unable to connect" from firefox. I'm sure this is not a pound problem, so I think it's in the iptables, or maybe I should be installing some extra software that I'm unaware of.

OpenSUSE :: Virtualbox Guest Additions: Set A Shared Folder In 11.2 Guest

Mar 4, 2010

OpenSUSE installed in a Virtualbox Virtual Machine and I want to set a shared folder.

1 - Set up a Virtual Machine and install OpenSUSE 11.2

2 - Create a shared folder on host (HostFolder)

3 - Setup the shared folder in Virtualbox Via the Virtual Machine details or via Devices > Shared Folders...

4 - Install dependencies for running the Virtualbox installer You need to install the right development kernelpackage for your machinetype (use 'zypper search -i kernel' to see what's installed) sudo zypper make gcc kernel-source kernel-hosttype/default-devel

5 - Run the Virtual Machine and go to Devices > Guest Additions This mounts an iso image in your OpenSUSE guest.

6 - Open a root terminal and run

cd /usr/src/linux
make oldconfig && make prepare && make scripts && make dep
cp ../linux-obj/$HOSTTYPE/default/Module.symvers .
make prepare

* A commenter on previously mentioned thread says this step is unnecessary but it doesn't work without on my system. I suggest trying step 7 first and returning to step 6 if that fails. *

7 - Run ./VirtualboxLinux yourhosttype .run from the mounted iso image.

8 - Create shared folder in OpenSUSE (GuestFolder)

9 - Test with sudo mount -t vboxsf HostFolder /home/user/GuestFolder It works? Great! Let's set up the system so it automounts for your regular useraccount instead of root-only access.

10 - Add this line to /etc/fstab HostFolder /home/user/GuestFolder vboxsf defaults,uid=1000,gid=1000 0 0

11 - It works for me but if it still doesn't automount after a reboot; sudo mount -a

Debian Configuration :: Exim4 Configuration For Local Addresses

Jun 17, 2010

I am working on a Debian 2.6.26-19 Distribution with exim4 as MTA. After a system restart a problem occurred with delivering emails to local addresses. These local addresses use a 1and1 mailserver for email. The MX records for the local domain are set correctly but exim does not use a DNS lookup for these addresses because it identifies them as local addresses. I figured this out by executing the exim4 -d -bt command. The dns lookup part of the result looks like this (I replaced the actual address with placeholders):

[Code]....

The eventual result of the exim4 -d -bt command is: [user]@[domain.ext] is undeliverable: Unrouteable address How can I make sure, that exim4 makes a DNS lookup for the local addresses instead of skipping it? I know that I have to edit a exim4 configuration file, but I could not figure out which and how.

Fedora :: Installing Guest Additions Virtualbox 13 Guest?

Jun 3, 2010

I had a lot of trouble installing Guest Additions within the Fedora 13 Guest on a Linux host. I had to mount the vboxGuestadditions.iso from the Device --> CD/DVD Devices menu. Then I located the appropriate package for my system. In my case it was the AMD64 Linux version.I ran this as administrator in Terminal. I used the "bash" command followed by the package name. This was after CDing the the appropriate directory. The packaged installed, I then rebooted and it worked fine. (Something that would make this easier is to load a script into nautilus that would allow me to open a locatation as administartor at the open window. I'm sure there is something in Fedora to do this but I couldn't find it in a hurry so I used the command line way).

Networking :: How To See Host Only Folder From Guest

Feb 2, 2009

My Windows guests see my VMware Host Only folders as \.hostShared Folders. But when I try to see them from a Linux guest, all I get is frustrated. No permutation of that seems to work. Because the Windows guests see the shared folders I know the host is doing its part in providing them. After two days of not finding an answer on the VMware Workstation forum I finally figured out that the problem really is how to look for them with Linux. With Linux I can turn off all NICs accept the Host Only NIC, put smb://172.16.138.1 into the address bar and see all the shares on the host, but not the folder designated as the host only folder. How to look for the shares with Linux?

Networking :: Connect VMWare Guest To Host?

Sep 14, 2010

I have VMWare on a notebook, guest Windows running on Linux host. The network in that virtual machine is configured as NAT. I want to share/transfer files from Linux (host) to Windows (guest). So I leave sshd always running on the notebook, I go into Windows and run an SSH/SFTP program. My Wifi router has address 192.168.1.1, my desktop has address 192.168.1.2 and my notebook has address 192.168.1.3. On the notebook, that SSH/SFTP program connects to 192.168.1.3 (i.e. the notebook itself) and everything works fine. But it's a notebook, and when I leave home with it, 192.168.1.3 is no longer accessible. How can I let the guest OS connect to the host OS when I'm away from my Wifi network?
