Ubuntu Installation :: No More Network Connections After Update?
Jan 9, 2010
I'm running VBOX OSE and wanted to access files on my native machine (ubuntu 9.10) from my virtual machine (Windows XP professional)
Now, I can ping the native host from the XP box, but can't access the share.
I have tried re-sharing the directory but it won't work.
Another interesting aspect is that I can't access the VBOX either. It gives me the error:
"Error: Failed to retrieve share list from server Please select another viewer and try again."
Up until this morning it worked just fine.
Unfortunately I didn't pay attention which software was updated during the process.

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.

I have openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections. I want to play with my friends some lan games, but we are in different networks, so i want to create this gateway server so we can connect with VPN clients to this server and play freely.

Does anyone know how to permanently enable X connections from all machines on my local network. I keep having to enter 'xhost +' to allow X connections.

I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.

I have no Internet Access with Firefox
I first tried an upgrade from 11.3 to 11.4 and lost Internet Access, so i re-loaded 11.4 from scratch on clean partitions.
I am connected to my wireless WPA2/PSK connection, have an IP, am able to see the network.
I turned off and disabled the SUSE firewall.
I tried setting Firefox proxy settings to auto and to none, i dont use proxy.
I am currently posting this through an SSH connection to my 11.1 server from the new install of 11.4 on a Dell latitude D600 laptop (not using the on-board Broadcomm that is an issue for a later date).
I am running out of ideas anyone got a clue.

I had a google of this but can't find anything useful. I use networkmanager to configure my wireless card. Currently this only works when I'm logged in to KDE. If I log out the system loses the network connection. Is there a way to make it persistent using NetworkManager?

I have my box setup as a router/NAT with two different network cards. One for external connection(connected to the Cable Modem) one for internal connection(used for internal DHCP). It works perfectly when I manually activate the two interfaces after booting(both interfaces always show up as inactive after booting), then the DHCP server and firewall. I am confused, however, by which program has control of these interfaces.
First, there is the Network Configuration (System->Administration->Network), which is where I manually start the interfaces after rebooting. Both interfaces are set to "Activate when computer starts" in here.
Second, Network Device control(System->Administration->Network Device Control), which looks to be almost the same thing as the above.
Third, the NetworkManager applet(on the top bar) - both devices show up as unmanaged when I left click on this, but if I set "Controlled by Network Manager" in the "Network configuration" window(number one above), It still does not work. Can I get rid of two of these programs, or is there some way to edit the startup scripts to start my ethernet cards before the dhcp server/firewall(which is shorewall BTW)?

I just finished a fresh install of 11.3 on an HP 7900 small form factor and have no network connectivity. In Network Tools eth0 shows the state as inactive. Network Connections didn't have a connection, so after letting it create one there is no MAC address. I copied and pasted the MAC address from Network Connections eth0, set up a static address with default gateway, netmask, etc. all set appropriately and rebooted. Still no joy.
I want this to get an address via DHCP, I just set up a static address for testing.11.2 sensed the NIC without issue, but 11.3 doesn't seem to like me right now.I wanted to get this deployed on 40 machines today. Oh well.

I remember when using openSUSE 11.3 with KDE 4.5, the network connections started to show the last date used for my "NIC".I am using the plasmoid-networkmanagement plasmoid and KNemo.After I downloaded and installed openSUSE 11.4 64-bit, the network connection no longer shows the last date used. I have set up my card via Yast and Iam connected directly to the Internet. No proxy.To find where this is located, navigate to:Configure Desktop --> Network Settings --> Network Connections --> Wired tab.

I ran an update on ubuntu server today, and after a long install process, it spat out an error, telling me to run "sudo dpkg --configure -a". After I ran that command, I was no longer able to access my website or forum. I could really use some help with this one, I've tried so many things including disabling shorewall, restarting apache, so many things...

First a warning that I'm so clueless it hurts. Initially I entered the Linux world as a solution to my blue screening Alienware Aurora desktop (which later fried anyway ironically enough). I decided to give up on Windows for everyday use cause you can't strangle an operating system. My first and there after Linux experiences have been fantastic. Internet works without prompting through various distributions of Ubuntu, Mint, and KDE with the exception of enlightenment.
But now I come to openSUSE 11.4 and as my title suggests I'm having a hard time connecting to the internet. I've got a wireless card and router and all that jazz but I can't even select the options for wired or wireless connections under Network Connections in the Network Management Settings. Everything is greyed out except for VPN. I even have the desktop wired to the router and it still is not giving me any indication that it will connect.
I'm wary of trying to enter ip addresses and things of the like because I honestly don't know what i'm doing here.
My router is a Netgear N150 Wireless WNR1000 and in the Kinfocenter under Device Viewer I found my wireless card to be a RaLink RT2561/RT61 802.11 g PCI and my wired device thingy to be an Intel 82540EM Gigabit Ethernet Controller.

I'm usually on 8.04, which I like to keep up to date. This morning, after downloading and installing the latest automatic update, the system refuses to recognise that I have any kind of network connection. I know it's not the hardware, as I'm reporting this on the same machine booted as something else. Is it possible to 'undo' recent updates ? and, if so, how ?

i am too new for linux..I installed Ubuntu 10.10 desktop edition from windows.When i am trying to configure network connections i am facing problems
Code:
udo pppoeconf
no working ethernet card could be found.If you do have an interface card which was not autodetected so far,you probably wish to load the driver manually using the modconf utility.Run modconf now?
/usr/sbin/pppoeconf: 523: modconf: not found Ifconfig

I installed 10.04 yesterday. The computer had an MS OS on it but I chose to format the entire HD for Ubuntu. The install seemed to go fine. When logged in there were updates available, and I installed all of them. After a reboot I tried getting on the internet and found that my network was 'disconnected'. I've checked the cabling, and that the LAN is still enabled in the BIOS. I assume the network had to have been functioning to do the original update. How do I figure out what changed. I've been reading the network section of a Linux book and came up with a little data that might help. My hardware is listed after the host file.
$ ifconfig
eth0 Link encap:Ethernet HWaddr e0:cb:4c:b6:6b:d6
UP BROADCAST MULTICAST MTU:1500 Metric:1

Here is the layout of my network:My cable modem plugs into eth0 on my ubuntu server which acts as a firewall (shorewall) and dhcp server to my lan. A dd-wrt access point is plugged into eth1 and then a bridge connecting my xbox360 and another bridge connecting a desktop computer.Everything works pretty well, except a few times a day, my network will just shut down. The wireless on my macbook and my wife's laptop will just shut down, and if my xbox is running, it will lose connectivity. It will be down for maybe a minute or two, and then come back up like nothing ever happened.I never had this problem when I had just a dd-wrt router running everything instead of my server.When I ssh into my server afterwards and run dmesg, this is what I will get:
Code:
[398598.251548] martian source 169.254.1.255 from 169.254.1.33, on dev eth1

Somewhere I've lost the Network Manager. it is listed in the installed programs as well as I can see all the components but do not see it in the menus anywhere nor the icon in the top panel... So even though I can connect to the wifi networks that I have connected to before it is very difficult to connect to new networks using Network Connections or so I find... I've tried reinstalling it many times but always find it saying installed but can't really access it... So how can I change that or are there a better network connection manager out there ???

i've installed ubuntu 11.04 on a friends Asus Eee pc 1005HA netbook. after the installation i tried to connect to the router using wireless, and when i enter the key, it fails to connect, so i tried using an Ethernet cable to connect but that doesn't work either,the network devices on the computer are:
Atheros AR8132 PCI-e fast ethernet controller
Atheros AR 9285 wireless network adapter
It lists the wireless device and the solutions to the problem, however, the solutions seem to be for Ubuntu 10.04 and also 10.10, and im not sure if it will work for 11.04 so far i have been unable to find out anything on the forums about the ethernet

I'm toying around with ubuntu + LTSP. I've managed to get the computers to boot off the network card "eth0". "eth1" is facing the internet. How would I go about the process to bridge the connections so the ltsp clients can access the net?

I upgraded my desktop from 9.10 to 10.04. The updated system works without problem - except that apt-get/Update Manager/Synamptic does not connect to the net anymore.
When I try to check for updates with the update manager, I get the message below. I have set different servers with the same result, and checked if there is a proxy set up somewhere, which is not. I also tried apt-get with the fix flag.
When I access the uri's with a browser, that works without a problem.
Message from update manager:

I am total newby in Ubuntu 10.04. I have just installed it in my office where I have two networks card one connect to a router giving the internet access and the other connected to the windows based work network providing access to the work network sources. In XP everything works fine as I can keep both connections alive and have the results I want.
However although I don't know how to do it in Ubuntu 10.04. Till now I have setup the first connection directly to my router and I have internet access but I cannot set the other one. Another question is how I can force ubuntu to use the router connection as the default one when I log in.

Since I installed ubuntu 10.04 I dont see my eth0 card in System->Preferences->Network _connections. Everything works fine but it puzzles me. In ifconfig iI just see the eth0, networking seems to be working fine, but it keeps puzzling me. Adding theinterface is no solution: add it and it doesnt show again

Using xubuntu 11.04, how do I maually give myself a static IP address and other IPv4 settings? I see the edit connections panel and saved a setting there but can't see how to use that setting. The only useable setting when I'm connected by ethernet is Auto eth0.

once I updated , there will be no connections to Internet in GUI , while it's available in TUI . So it's wired , huh ? Before upating, it's available both in TUI and GUI, though all the time the network-manager shows no connection , in fact , there is and both GUI and CUI . Now I updated , and it can't access Internet from GUI.
