Debian :: Edit Connections" Shows That Ethernet Is Shown As "device Not Managed?
Jun 20, 2011
I have used the information available at wiki.debian.org/iwlagn to install firmware etc for my Intel Pro Wireless 4965 card.According to the network applet the connection is good, but it only seems to work when my ethernet cable is plugged in.I get no connection without the cable in, even though clicking on "edit connections" showshat ethernet is shown as "device not managed".With the cable plugged in I can get emails. Iceweasel will connect to the internet, but Epiphany will not.Without the cable I get no internet connection at all

I'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.

I use my T61 both wireless and in the dock, where I switch to the wired connection. After the latest round of updates, I seem to have lost the ability to switch to the wired network. When I turn the laptop on, I see it connect to the wireless network, but when I left click on the tray icon under Wired Network is says Device not managed. I have not made any changes to anything in the last couple weeks, besides some updates. How do I go about getting the wired network back in there?I tried to add eth0 back into System - Preferences - Network Connections, but whenever I try and add eth0, but it still says Device not managed.

I am trying to add an OpenVPN connection from the Network Connections GUI. The problem is everything is greyed out when I am logged on as a user. When I log in the GUI as root I can create the OpenVPN connection no problems. The problem with that is the option to use my newly created VPN connect does not appear when I log back into my user. I have tried adding my user into the sudoers file to no avail.
How can I give my user privileges to add OpenVPN connections?

My dad has an older netbook that I installed Ubuntu 10.10 to, but he complained that it was too clunky.So I did what any good son would do and installed GNOME and Ubuntu themes on top of the minimal version of Ubuntu 10.10.It does run much faster, but I have a small problem with the Notification Area: nm-applet IS running.Notification Area is added to my panel, and in view.I have two interfaces, one wired, one wireless, both function correctly (both manually configured with gedit)
Neither one of the aforementioned interfaces are being displayed in the Notification Area, and my dad is not familiar with Ubuntu or any of the commands, so this is really a must-have for him.

when I first installed it on my IBM thinkpad, the eth0 was working correctly. I had someone try to install the network card for me, and something was changed to where now the wired connection is displaying "device not managed".

Brand new Acer laptop | Intel chipset
Ethernet controller: Attansic Technology Corp. Device 1063 (rev c0)
During this week, I installed Debian twice on this system using NetInst, connected trough ethernet. Yesterday, I noticed the ethernet controller wasn't listed by lspci. I restarted, it appeared but didn't work. I turned off the system, started it a bit later and the device worked normally. This odd behavior has happened during the last twenty four hours. The ethernet controller appears and disappears. I enabled the "Boot from LAN" BIOS option to check the availability of the device right upon start and I'd say there's a 50% chance that it doesn't appear. I posted this message connected through the ethernet device.
I guess I should return the laptop because of this problem but I know very little about hardware and I wanted to ask first.

I just did a fresh install of Squeeze with a KDE desktop on my computer. I use this computer to run an instrument in my lab. The instrument is connected to my computer through an ethernet card. Since my reinstall I cannot figure out how to get my computer and instrument communicating again. I'm guessing that I need to somehow tell my computer to connect to the device, but I don't know how. Here is my interface configuration:
[Code].....
I think my instrument is connected to eth2, which does not show any inet addr or Bcast ip, so I'm guessing that is a problem. How do I fix this?

I think that's all that would be needed to help diagnose the issue. I'm kinda new to linux, and this is primarily a music machine.

Currently my setup is a road runner cable modem connected to a desktop via a ethernet cable. The networkmanager lists "Broadcom BCM440-BO 100BaseTX" device not managed. I've turned off the power to both the cable modem and the computer. I then turned on the power to the cable modem and then the computer. If I try the firefox browser, it can not connect to the internet.

I installed Linux 6, configured the network during the install with a static IP and when I do an ifconfig command it doesn't show an IP Address. Can't get out to the Internet because I don't think I have an IP/Address. I restarted network, went into preferences-network connections and everything looks fine, ran system-config-network and everything looks fine. When I do an ipup ifcfg-eth0 and get the message "Connection activation failed: Device not managed by NetworkManager". Is there an option I failed to load at install or I need to install now?

After the use of pppoeconf, the network manager does not recognise neither the wired nor the wireless connection anymore. (It nicely did it before that) I tried to replace the etc/network manager folder with that of a different machine. Still the same. What else can I do to reset Network Manager ?

I'm having trouble getting onto the internet with ubuntu 9.04. I have just moved house and have just got the internet set up here (typing this on windows laptop with wireless). My ubuntu desktop is plugged in to the network, but in the top right hand corner when I click on the network icon I get: "Wired network device not managed"
In my old house I had a static IP. Is this anything to do with it?

Yesterday I did an upgrade and today my box is unable to connect to the internet.
I have tried another cable, it didn't help.
Basically NetworkManager does not connect eth0 to the network, if I try to run ifup from the command line I get:
Code:
I can see in network configuration settings, that the device has been correctly detected and eth0 interface is correctly activated, yet when I try to uncheck the box manage by NetworkManager and start it manually, it tells me that the cable is disconnected... I've tried two different cables, different ports on my router - no help.

I've been searching for a couple of hours and have not found any threads that solve my situation... hope I'm not repeating something here.
Setup: Notebook with openSUSE 11.2 using KDE 4. Using Network Manager to manage network connection (although I've tried configuring this using ifup as well with no luck).
I need to be able to connect to client networks via a network cable (Ethernet) and connect to the internet via my MiFi 2200 Mobile WiFi. Both cards/connections are active with the following:
I have no problem mounting drives from the client's network. But, can not reach the internet. If I disconnect the ethernet cable, the browser will immediately connect to the internet and load web pages.
I'm assuming the ethernet connection is taking precedence over the wireless connection?
I can't imagine that there is not a way to set this up. If Windows can do it, I'm sure openSUSE can!

I messed up my Network Connections when I put a different NIC in my computer. Now I just went back to using the old NIC. It shows up in ifconfig, but the GUI Network Connections is blank. When I manually Add the connection back to the GUI Network Connections, the settings are not reflected when doing ifconfig.For example, I change the IP address for eth0 in GUI Network Connections, save the settings,

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.

I am having trouble with connecting my Sony Ericsson phone with my Ubuntu 9.10 using USB. It doesn't matter how I choose to connect it - "File Transfer" and "Phone Mode" - both does not work. The phone IS charching, when it is connected, but it doesn't shows anywhere. When I type "lsusb" in terminal, it does not show me my phone. When I look in "/var/log/messages" there is NO error. It does not even show the procedure of connecting and disconnecting the phone. What could be the problem?

Every single time I enter the network manager to edit connections is crashes on exit. I am running opensuse on an Asus eee PC 1000HE with an Atheros network card. The crash report follows :
Distribution: openSUSE 11.2 (i586)
Gnome Release: 2.28.2 (null) (SUSE)
BugBuddy Version: 2.28.0
System: Linux 2.6.31.12-0.2-default #1 SMP 2010-03-16 21:25:39 +0100 i686
[code]....
As an extra point. I wish I could disconnect individual networks instead of just disabling networking to disconnect. I think the newer version of the network manager does this.

I want to disable the touchpad while typing on my girlfriends samsung nc10 netbook. (she always selects and deletes text accidentally.. )
I though, this would be possible with gpointing-device-settings. But there, the touchpad is not shown, only a IMPS/2Logitech wheel mouse is shown. Although there is only the touchpad and no mouse...
So how can I enable touchpad configuration there?

My wireless connection has been giving me some problems, so I decided to try a wired connection directly to the router. However, when I try to do that, it doesn't work. When I click the network manager icon, it says that the wired device is not managed.
ifconfig gives this:
Link encap:Ethernet HWaddr 00:13:d3:dd:12:79
inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::213:d3ff:fedd:1279/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[Code]...
I ran sudo dhclient to try release and renew my IP, in case that was the problem. It released and renewed successfully, but still didn't connect to the Internet.

I have a Kingston 8gb Datatraveler that has been giving me troubles lately. For some reason after I delete files from it it still shows up as full and the files are shown in the hidden trash files. How do I get rid of these files? I can't delete them as they just show back up. Also, I tried to format the drive with gparted and it won't unmount. When I right click and select information, at the bottom it says: Unable to find mount point. Unable to read the contents of the file system. Because of this, some operations may be unavailable.

I am trying out a Debian system on my at home desktop. The way that the desktop connects to the internet is via a wireless card. The installation went fine to my knowledge, I used a CD and the installation even used the wireless internet (albeit slowly) to download the needed packages to complete installation. Now when I try to connect to the wireless network Network Manager says that Wireless Networks are "not managed." I feel like I'm probably missing something either really simple and silly or something really big requiring a re-installation. Either way I can't even find an instance of this happening to someone else's system.

I was just using the mic and watched it stop working suddenly. I was in the middle of a skype test call when the graphical mixer level died down to zero in the middle of the call. When the test call was played back, the first part sounded fine then the sound got lower until it became inaudible. Since then I can't get any sound from my mic in skype.
Also, the audio input level graphically shown in Sound Preferences shows no fluctuations in sound as it used to before. The input device is enabled. I tried using Sound Recorder to record some sound clips and that worked fine. So the mic is working but Sound Preferences and Skype seem to have the mic level really low. I'm not sure what else to think considering it was working perfectly a few minutes ago. I've tried restarting, but that didn't fix it either.

Does a firewall exist, that shows "whois" info for ALL new connections that are attempted? Or even better, "smartwhois" info?New connections meaning, connections to IP blocks never connected to before. So you go to a site that belongs to owner A, and if an attempt is covertly made to connect to another site that belongs to owner B, an alert is shown and you choose if you trust this owner.
