Fedora Networking :: Eth0 No Longer Managed In NM

Aug 27, 2010

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.

Fedora Networking :: Eth0 Connection Failed - Device Not Managed By NetworkManager

Aug 10, 2010

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.

Ubuntu Networking :: Nm-connection-editor Eth0 Not Managed

Aug 25, 2010

I'm getting rather fed up with this Network Manager applet on Ubuntu and its seemingly erratic behavior.I often use my laptop for things like dhcp server to do pxe boot on other machines for netboot installs and other stuff. Often I have to set static address on eth0 etc.I know how to set a static address for eth0 by editing /etc/network/interfaces and all that good stuff, but when I click on the Network Manager applet, it says 'Wired Network - not managed'.I may have deleted it for some reason, but why does it no longer appear, even though eth0 is working?I've also found in the past that changes to interfaces in the Network Manager, such as giving eth0 a static address, do not seem to stick?

Fedora Hardware :: Eth0 Device Not Managed?

Fedora Networking :: Bridged Networking And NetworkManager - No Network Connection Because Network Isn't Managed

Mar 2, 2011

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)

But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)

The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.

Is there a way to have both of these pieces of functionality?

I am using FC14

Networking :: Eth0 Fixed IP - Eth1 DHCP Gateway - Access To Eth0?

Aug 19, 2009

5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.

I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.

Code: echo !HH | nc 192.168.1.6 80

I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?

Networking :: Production Server With Static IPs On Eth0 And Eth0:1 - Getting Private LAN On Eth1?

Jul 1, 2010

I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.

My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...

The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2

Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...

I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).

Slackware :: Eth0 No Longer Recognized After Upgrade And ASUS Mobo Replace In -current

Jan 27, 2010

My office has a box which is, by necessity, dual-boot WinXP/Slack. The Slackware I'm running there is -current, all great and fine. Until now... It turned out that my mobo, an ASUS P5KPL-CM, died after a power surge. Since the XP needs software activation, we replaced it for an exact copy of the mobo. After the change the box worked fine in XP, and I was able to connect to the network via the Ethernet interface. BTW, the Slackware version is Slackware-current, updated as of the Jan 9 update (after that I was no longer able to connect to the Net with Slack). However, in Slackware there was a problem: eth0 was no longer recognized. Using /sbin/ifconfig only listed the lo (loopback) interface. The lspci output is:

Code:

01:00.0 Ethernet controller: Attansic Technology Corp. Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (rev b0)
Subsystem: ASUSTeK Computer Inc. P5KPL-CM Motherboard

Networking :: Ignoring The Unknown Interface Eth0=eth0?

Dec 18, 2010

I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side. In Lucid I can ping my router, and the network manager says I'm good to go, but I can't get to any web sites. It all started when I tried to put my laptop on another network by mimicking the settings of a computer I had just unplugged from the network. MAC address and all.

ifconfig eth0:

Code:

eth0 Link encap:Ethernet HWaddr 00:1f:16:ba:4c:8c
inet addr:10.136.9.147 Bcast:10.136.9.159 Mask:255.255.255.240

Fedora Networking :: Cannot Get IP Address For Eth0

Aug 2, 2009

I downloaded Fedora 10 32bit and put it on a Dell Dimension 8200 to save it from the recycle bin. Everything seems to work except I cannot get an IP addr. Roadrunner is my ISP using a cable modem and a Linksys Instant Broadband Series Etherfast Cable/DSL router model BEFSR41. In system-config-network, the nic shows inactive. If I activate it a window opens saying "determining IP information for eth0". After a short time the message adds the word "failed". Using a Windows PC on the same network, I can look at the DHCP connections on the Linksys and I see the MAC addr for the PC running Fedora.

From the OS installation, /etc/sysconfig/networking/devices/ifcfg-eth0 has following:
DEVICE=eth0
HWADDR=00:80:ad:d1:88:c9
ONBOOT=yes

Fedora Networking :: Eth0 Restricted To LAN Only

Jun 21, 2010

I'm guessing this is a r8169 problem. This worked for a while after upgrading to fc13 (from fc12)

I'm not able to get off the local network with eth0. I can though with eth1. Both interfaces are connected to the same switch and have the same network, gateway, and dns server addresses.

The odd part is I am able to ping eth0 from off the LAN and get a reply.

Wireshark capture is attached.

Fedora Networking :: Eth0 Says Inactive On F10 Reboot

I just installed Fedora 10. I entered my static network info in Network Configuration. When rebooting, the eth0 says Inactive. I've read many articles about this problem on earlier versions and tried many of the suggestion, but have not found a definite way of solving this. Is there a better way or a workaround to get this machine on the network?

I'm using Fedora 12 on a box with 2 separate NICs in different subnets. The problem is that after a reboot, both NICs always show up as eth0 when you left click on the networking icon on the top right. I have to manually change one of them to eth1 & then things start working.

DEVICE=eth0

Fedora Networking :: How To Manage Eth0 While Use Gnome

Jun 3, 2011

I'm using Fedora 14 with gnome as my GUI.As you know , there's gui tool which manages network adapter , either wireless or wired.After every login into fedora , I should click on network manager icon on taskbar and choose System eth0 to establish and enable eth0. I want it to be done automatically.

Previously , I used opensuse 11.4.It has a tool in yast which allows you to choose how to configure your network adapters , traditional or knetworkmanager mode.I can't find this like tool in gnome on fedora.

how I can configure network adapters to start or not during startup?

Fedora Networking :: 12 - Networking Eth0 And Eth1

Jan 12, 2010

I am trying to setup linux box as router.

What i am trying to do is:

1. I am trying to setup NIC via network not NetworkManager
2. I have assigned the ip to both NIC with #ifconfig eth0 192.168.1.1
3. #Ifconfig shows my nic and ip
4. restart the service network .
5. #ifconfig shows nothing. NO NIC card

I dont want the network manager coz i dont want to install the gui on router and network manager works only in gui mode. ( i think my this understanding is correct)

I tried to configure the NIC with Network Manager

When ever i restart the network service i have no out put from ifconfig

I tried to configure the NIC with #setup command as well and select the dhcp option

I can not find any ifcfg-eth0 in /etc/sysconfig/networking-scripts/

Ubuntu Networking :: Wireless PC Card Not Managed By Nm-applet?

Jan 11, 2011

I'm trying to get a wireless PC (PCMCIA?) card working under 10.04 desktop. It does not seem to be recognized by nm-applet and I cannot see any particular reason why. I have disabled the built in wireless (Intel 2200) in both BIOS and by blacklisting the appropriate module so there should be no interference from that. The card is a Linksys WPC300N V1. It has Power and Link/Act LEDs both of which remain dark.

Here's the information I have collected regarding the card:

lshw:

Code:
hbarta@willow:~$ sudo lshw -c network
*-network
description: Ethernet interface
product: 82540EP Gigabit Ethernet Controller (Mobile)

[Code]....

I saw a comment about 'You need to have "managed=true" for NetworkManager to bring the interfaces up. in '/etc/NetworkManager/nm-system-settings.conf and did so but I see no change.

I understand that modules must be compiled to support network-manager but I would expect that to be the case with modules that ship with 10.04. I don't see any obvious indications for why this is not coming up with network-manager. Is there something I;m overlooking or something else I need to do?
