Networking :: VirtualBox - Connecting Host And Client

Oct 15, 2010

I am trying to config linux box as router.

I have CentOS 5.5 client and host in VBox. I can't connect them (I am using bridge adapter mode) as I don't have router in between.

I just created DHCPD on host, and followed


But that don't seem to work also. Host is and client is but when I ping host from client, it says Destination host unreachable.

Networking :: Connecting Debian Client To Voyager Client Via Crossover Cable?

Jan 6, 2011

trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:

# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp

Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used and used a NetMask calculator to give me a NetMask of (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:

# The loopback network interface
auto lo
iface lo inet loopback


I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?

The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?

Networking :: Connecting Through XP On Virtualbox?

Dec 13, 2010

I can connect to the Internet using the Windows Drivers for my USB iBurst pppoe modem running in a VirtualBox VM running Windows XP on my Ubuntu 10.10 host. I haven't been able to get this working under Linux.

Is there any way I can connect to this from the Linux host.

Networking :: Vpnc Working Under Virtualbox Under Windows But Not On Host?

Aug 8, 2010

Our company uses a customized vpnc (based on and almost the same as vpnc 0.5.3). I first tested it on a Windows host under Virtualbox everything works straight away. But when I want to use it on a Linux host directly it always ends in "No response from target". I have tested this on Fedora 12 and the latest Ubuntu.
I thought of firewall settings but iptables -L on Ubuntu returns an empty list even.

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 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 As I say, I manually made no config changes.

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 ( from the host ( 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 through to the default out at, but it's not. I think a clue is in routing, but I don't know what's wrong.

Networking :: Samba Setup - Windows 7 Host - CentOS Machine Using VirtualBox?

Is there anything that I should do different or anything that I should be aware of? Also, once this is set up, how do I transfer files between the two machines?

Ubuntu Networking :: Connecting To UWF's EDesktop Via Terminal Server Client?

Apr 27, 2011

I'd document here the way to get to eDesktop through linux (debian, ubuntu) at the University of West Florida (UWF), since they appear to only support Windows through their documentation on the University web site, and the link through Argus (the secure web site) doesn't work in Linux. This is sometimes needed to use the University resources (libraries and computer programs) from remote locations, and otherwise a google search is fruitless. I had to have a guy in the computer science department show me how to do it. This may apply for other Universities with similar setups. It was impossible for me to figure it out on my own, I had to go back to my old 9.04 partition to get the info...

1) Open Terminal Server Client (Applications>Internet>...)

2) Insert as follows:


Protocol: RDP


3) OPTIONAL BUT RECOMMENDED click Save As and save it as a quick connect so you don't have to refer to this again.

4) Flip through the other tabs and configure as desired, and click Connect!

General :: Distro To Use As VirtualBox Host?

Apr 23, 2011

A family member has got a windows PC (with a Pentium 4 w/o hardware virtualization support) that keeps winding up infected and crudding up. As I would like to minimize family IT support time, I figured the easiest thing to do was to wipe it, put Linux on it, install XP pro (they don't want a more recent one) in a VirtualBox virtual machine, and take a snapshot. I'd set up a shared drive on the host where they could store all their stuff, so that when it inevitably gets hosed, all I have to do is roll back to the snapshot.

This leaves me with the question - which host distro would be the best choice? I'm looking for three things - ease of maintenance on my part (updates, configuration, etc.; I have a background in slackware, but have some exposure to Ubuntu), minimalism (so that the bulk of the system's resources can be devoted to the VM), and virtualization-readiness (say, so I can have the computer automatically go from power up to virtual machine power up, thereby minimizing the user exposure to the host).

Obviously, I would like it if it has all of the standard tools that will allow me to do remote maintenance, also.

I've looked at Ubuntu server JeOS, and it seems enticing, but I can't seem to find out whether it can be used on a desktop system, i.e., with a GUI, etc.

Fedora :: VirtualBox Ping From Guest To Host?

Dec 9, 2009

I have VirtualBox v3.1.0 r55467 running on f12 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.


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:


Stopping VirtualBox kernel module [ OK ]
Removing old VirtualBox netadp kernel module [ OK ]
Removing old VirtualBox netflt kernel module [ OK ]


dmesg gives me nothing. I have scoured the web .. and even asked on #vbox and #fedora cant get.

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...

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?

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?

Ubuntu :: 11.04 Host In VirtualBox - Unity Config

Apr 28, 2011

I just installed 11.04 32 bit (downloaded today) in Virtualbox (4.0.6), with host 64 bit Win7. I'm trying to get Unity working. I've searched and found references to the fact that the Host graphics card must support 3D, which I believe mine does (nVidia GeForce 7900 GTX). Also found some references to try the following:

After the OS install, I did this:
sudo apt-get update
sudo apt-get install virtualbox-ose-guest-utils

Then rebooted and did this:
killall -9 gnome-settings-daemon && gnome-settings-daemon

I also installed the latest Guest Additions. In the VM settings I have the "3D" tick checked, and have 32M RAM allocated to video. But no Unity shows up, just normal desktop.

Any ideas?

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
