How to access guest VMs from outside network?

http://askubuntu.com – My problem is how to access guest VM from outside network. I am going to describe my problem in details. I have single machine with Ubuntu Server 12.04 LTS contains two NICs. One NIC is connected to my gateway(i.e. 10.0.0.1) and 10.0.0.3 is IP address of this interface. Another NIC has IP 192.168.0.3 but this is a part of Bridge(i.e. br0). I created two guest Ubuntu 12.04 LTS Desktop VMs with IP address 192.168.0.100 and 192.168.0.110. My /etc/network/interfaces file is as following: The loopback network interface auto lo iface lo inet loopback The primary network interface auto eth2 (HowTos)

Hey all,

I'm having a really odd issue.

I just upgraded my 11.11 server to 12.04, by performing a clean install.

I edited my /etc/network/interfaces file to the following:

Code: # This file describes the network interfaces available on your system # and how to activate them.

Hi !

Hi All,

I have 2 NICs in my U9.04 Server box (eth0, eth1). After I added 2 virtual interfaces for each physical interface (eth0:1,eth0:2,eth1:1,eth1:2), the MAC addresses of all the interfaces have changed to that of eth0. Because eth1 was configured to be on my local network, I can't access the box remotely anymore.

Have a 'new' mailserver running postfix on Ubuntu.

We are having some problems configuring the subnets & interfaces.

Basically 2 subnets (.253. & .254.) need to be connected through the 3rd subnet (.252.) where the Router is residing.

# This file describes the network interfaces available on your system # and how to activate them.

I am running Ubuntu Server 12.04. I have a wireless USB card. When I begin the boot process I see:

Waiting for network configuration

It turns out that the network never comes up. But once I get to the command line, if I type: ifup wlan0, then I have network access.

I'm running a backported KVM on a Debian Squeeze. ATM the KVM-Guest can't connect to the internet through the bridge I have set up. The guests can reach each other, the host but nothing outside. I can neither ping, nslookup or do anything to a remote address. The guest are configured to have a static IP.

Virtualbox FTP to host 8 weeks 4 days ago

For testing purposes I installed virtualbox to simulate a linux(64 bit ubuntu) server.

I configured my network settings like this: Adapter 1: NAT Adapter 2: Host-only

with my etc/network/interfaces configured like this:

#loopback network interface auto lo iface lo inet loopback

# primary network interface auto eth0 iface eth0 inet dhcp

#the host-only network interface auto eth1 iface eth1 in

Hi there,

I am new ubuntu user. I have tried to configure wireless usb adapter on my 9.10 desktop. Adapter did worked fine, but I have problems with wired connection now:

I can ping my router. Skype works fine (don`t need DNS), internet on virtual machine (winXP) works too.

THis is CAT of interfaces:

Ubuntu 12.04, cli only, on an old machine

I swear, it was working. But now, on boot I get "waiting for network configuration" for a while, then it says "waiting an additional 60 seconds for network configuration". When the machine finishes booting, I have no network.
