Can't get "Bridged Adapter" to work in VirtualBox Network Settings
location: ubuntuforums.com - date: May 20, 2013
I'll start in this forum but may have to take the question to VirtualBox forum.
re: VirtualBox network configuration of VM Ubuntu-12.04.2 LTS server.
My problem is that I can't get Bridge Adapter to work in VirtualBox VM Ubuntu-12.04.2-i386-server.
I have the following configuration:
Ubuntu-12.04.1 LTS desktop as the host OS.Wired connection to cable modem.Installed the latest version of VirtualBox, 4.2.12.Installed on VirtualBox a guest VM Ubuntu-12.04.2 32bit server.
My problem is in setting up VirtualBox network so that I can access the guest server from my host desktop.
In VirtualBox Network Settings I have set Bridged Adapter (eth0).
However when booting up the VM a network connection isn't found.
When I login to the guest OS on VM and run ifconfig iI don't see an IP address against eth0.
If I try to run ping 184.108.40.206 from the guest OS I get ..
connect: Network is unreachable.
I cannot ping the guest server from the host OS.
If I then shut down the guest server and

I just jumped onto the Ubuntu (5.04) bandwagon, and I'm really impressed. I do have one question though. When I open the Newtork Settings application (System -> Administration -> Networking), the "location" I set does not seem to affect the settings. I am trying to have one wireless configuration for work and one for home where it is just a matter of changing the Location pulldown menu. When I try to change "Home," it seems to overwrite the "Work" settings.
Anyone have any suggestions?
How to copy Network Settings to a different machine
location: ubuntuforums.com - date: September 8, 2011
I have 30 Netbooks (+1 for my testing) used in our company for Academic Tutoring.
I rolled a customized version of 10.04 LTS running standard Gnome on my netbook, and used Clonezilla to copy this to the other 30.
One "small" (huge) mistake I made was that when I cloned the machines, I had not setup the 6 different wireless networks that these netbooks will be connecting to (5 locations in which these netbooks will be used so 5 SSIDs + 1 backup wifi router in case one goes down).
Now, I could enter SSIDs and (VERY Long) passphrases 180 times, but who the heak wants to do that?
The name of each machine is different ~ acer1 acer2 etc...but other than that the systems are identical. I manually went into each machine and changed the name in /etc/hostname and /etc/network/hosts.
Also, there is no encryption key for wireless networks (I had to agree on the test unit to store the networks in this insecure manner).
The 6 routers are setup using WPA2 with AES.
Reset All Network Settings (That's All)

Feeling guilty about hijacking, I'm posting here (setting myself up for the dreaded "double-post" chastising...)
The question is simple and was asked in another thread:
Is there a way of resetting all of the network settings to standard, as if a fresh copy of ubuntu had just been installed?
The resulting discussion trouble-shooting the OP's specific problems were detailed and informative, but failed to answer the fundamental question:
help me completely reset network settings to default
location: ubuntuforums.com - date: February 24, 2009
My network connections used to work fine until I started messing with them. I have undone my changes but now have odd problems. DHCP assigns all correct information but the internet still does not work. The only way I can make it work is by connecting using my Verizon WAN card and then the ethernet starts working (yes even after disconnecting the WAN card I still have internet).
My hardware works properly, I have tried /etc/init.d/networking restart and force-reload (don't know what force-reload does but i gave it a shot)
I also tried the same thing with /etc/init.d/NetworkManager
I just need to know how to completely reset my networking files to default as it came when i first installed.
Any help is greatly appreciated and if there is a duplicate thread i apologize but i did search for a couple days before posting.
Reset all network settings?
location: ubuntuforums.com - date: March 6, 2011
I've been having major problems with my wifi connection, the internet getting worse and worse, slower, bad connections, VPN dropping out all of the time etc (more info here: http://ubuntuforums.org/showthread.php?t=1692353)
Anyway, the wifi connection works impeccably under windows, and is worsening under Ubuntu. Ideally I do not want to have to format my linux drive and reinstall Ubuntu, thereby losing all of my settings, packages installed, etc. Is there a way of resetting all of the network settings to standard, as if a fresh copy of ubuntu had just been installed? Maybe removing the packages? Removing config folders? No idea how to go about that so I'd rather ask an opinion before breaking everything!
[SOLVED] Server network settings
location: ubuntuforums.com - date: July 3, 2008
Hello to all!
I have recently installed the 8.04 server edition on a spare machine that I want to use as a testing ground for hosting my own websites.
I found a tutorial that walks me through setting everything up the way I think I want it (for now) but I'm running into some issues.
I'm working to configure the file "/etc/network/interfaces" and I have some changes for my network I'm using the following:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
iface lo inet loopback
# The primary network interface
iface eth0 inet static
I think that is correct for my current router setup.
My problem is that I have never used VIM before and when I try to save the changes, I get a
[SOLVED] Linux Mint After update network settings do not work
location: linuxquestions.com - date: November 15, 2012
In the control center, the only option under Internet and Network is network proxy, which is of no use to me.
Under System, there is a Network Tools option, and here I can see the connections available on my machine (lo, eth0 and wlan0)
I am trying to disable the wlan0 to save power and just keep it off, and I would like to be able to configure the eth0 connection... okay sounds easy enough right..?
Well clicking on configure after selecting a device opens the "Network Connections" dialog (same one from Other section of CC).
However: there are no connections available! Under wired, when trying to add a connection, all the options are greyed out. I am wondering if possibly running Network connections as root would help, but there is no way to run it elevated from the control center.
Am i doing something wrong?
(it seemed to work previously... however that was thru the gnome-panel->network option, it showed all of the wireless networks available and it was q
[SOLVED] Editing network settings in a fresh CentOS 6.2 install
location: linuxquestions.com - date: April 29, 2012
After installing CentOS 6.2 yesterday, I've been having trouble figuring out the network settings so that I can access the machine through putty or secure ssh. I edited the /etc/sysconfig/network-scripts/ifcfg-ethlo in vi to give the machine a static ip address (192.168.1.3) and entered the netmask as 255.255.255.0 and set the router's ip as NETWORK=192.168.1.1 (which I got from my router).
I have access to the internet (I'm using the machine to type this) but can't seem to get access through ssh using port 22. I try to open the session, and just get a blank screen. I'm aware that I have probably missed something simple, but the answers I'm getting from various wiki's aren't providing any help, as they assume a level of knowledge I lack. Anyone have any thoughts?
I would prefer to make any edits using the command line and vi, as I am doing this to learn. Thanks in advance.
Network settings for bridged DDWRT
location: ubuntuforums.com - date: October 20, 2011
I am trying to set up my upstairs Ubuntu 10.04 desktop to use my upstairs router (running DD-WRT v24-sp2) as a wireless bridge to my downstairs router.
I believe the routers are set up correctly. Ubuntu can see both routers but cannot make the final hop onto the internet.
I have followed the instructions in
and all is as in the tutorials except when it comes to setting the desktop to obtain its IP and DNS automatically. I can do this in Windows but not in Linux. I assume it is this that is stopping me seeing the internet.
