Fedora Networking :: Eth0 Says Inactive On F10 Reboot

Apr 1, 2009

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?

Ubuntu Networking :: Eth0 DISABLED Upon Reboot - Lucid

Sep 7, 2010

Network card (82566DM-2 Gigabit Network Connection) is DISABLED upon reboot. Only way to bring it out of disabled mode is to rerun dhclient to obtain a DHCP lease. Upon reboot though, the NIC is back into disabled mode.

A workaround I have found is to uncomment the iface line in /etc/network/interfaces, but considering I have 14 identical PCs to this one, and only this one is currently giving me grief, I am trying to find the root cause

The machine successfully obtains an IP using the PXE boot option in the BIOS - so I can hopefully rule out hardware problems as a cause. Network cable has been replaced, as the location of the machine to a different switch port.


# The loopback network interface

Ubuntu :: Raid Array Inactive After Reboot?

Apr 24, 2011

I had some issues with my RAID6 array (with 15 disks), where 5 disks got disconnected (each five disks is connected to the motherboard via 1 SATA cable), which brought down the RAID array. I fixed this problem via readding the disks and running the array:


mdadm -R /dev/md1

However, after rebooting, the array appears inactive, and I have to go through the same motions to fix this and make it active.
The array is present in the /etc/mdadm/mdadm.conf, though also 2 other raid arrays (3 arrays total):


DEVICE partitions
# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes

General :: RAID Disk Inactive After Reboot

Aug 12, 2010

I just configured two raid setups but after a reboot they are not mounted and seem to be inactive.

md127 = sde1, sdf1 and sdi1 (raid 5)
md0 = sda1 and sdh1 (raid 0)
root@server /]# cat /proc/mdstat

ARRAY /dev/md0 UUID=65c49170:733df717:435e470b:3334ee94 auto=yes

As you can see they now show up as inactive. And for some reason sdi1 and sdh1 are not even listed. What can I do to get them back? To make matters worse I placed some important data on them, and even if I was clever enough to keep an extra copy on another drive, guess which drive that was? So, I need to get them activated as is (at least so I can get the data of them) before I can rebuild them from scratch. I'm running Mandriva 2010.1 and rated tehm using the built in disk partitioner.

Ubuntu Networking :: Connection To Network - Terminal: Ifup Eth0 Don't Fix Until Next Reboot

Mar 3, 2010

I have my ubuntu box hard wired into my network. It all works fine, until I reboot my ubuntu box. After reboot, it can no longer see the network. I have it set up with a static ip. Not sure that I set it up completely correctly but it works fine...when working.. To fix the problem, I enter terminal: ifup eth0 That fixes all know problems until next reboot. What do I need to do so that it will remember settings and automatically be hooked into the network at power up?

Fedora Networking :: WLAN Card Goes Inactive

Mar 5, 2009

I have been using FC10, it works well with wlan for sometime and goes inactive after some time and hence network goes unavailable. Even after few attempts to reconnect doesn't help. Rebooting helps in bringing it back temporarily.

Fedora Networking :: No Internet Connectivity - Status Inactive PAN0

Mar 3, 2009

I'm new to Fedora 10 and still a newbie with Linux in general. I installed F10 on an old PC I had....and the install went well..however, I'm having Internet Connectivity issues.

Here is what I did so far:
Did an ifconfig command and I have the following:
pan0 Link encap: Ethernet HWaddr D2:30:36:AF:61:95
inet6 addr: fe80::d030:36ff:feaf:6195/64 Scope: Link
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:30 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes: 0 (0.0 b) Tx bytes: 8676 (8.4 KiB)

When I go to the Network Configuration Panel I see the following:
Status: Device: Nickname: Type:
Inactive pan0 pan0 Ethernet

Tried to activate and it states Activating network device pan0, please wait... determining IP information for pan0.... A few minutes pass by then. It indicates it failed. Cannot activate network device pan0! I have disabled the Controlled by NetworkManger and enabled the Activate device when computer starts.

Fedora Networking :: Flaky Internet Connectivity - Network Inactive In NM Panel

May 28, 2011

I just installed F15 on a laptop that previous had F12 working well. During install, it finds my wireless card and seems to set it up fine. The full install ran with the wireless active without any problem that I could see. Now, when I start up, I see Network Manager tells me that the wlan is active, but it doesn't show my specific network. If I click on the NM tray icon and open up the panel, my network is shown but it is not "active".

I can double click on it and it will become active - shows the little globe next to the antenna. This works fine for about 2 web pages worth and then FireFox 4 stops being able to find web pages. If I go back to the panel, double click on my wireless network (which looks like it is active already), and reactivate it, I can get the page I was looking for in FireFox, but within a couple of minutes it will stop.

Likewise with yum, while I'm installing software, I'll occasionally get errors like this:
[URL]: [Errno 14] curl#6 - "Couldn't resolve host"
If I reactivate my wireless network in the NM panel, it continues fine. Other computers/phones connected to this network seem to work fine. Is NM known to be problematic in F15?

CentOS 5 :: Reset Eth0 Without Reboot

Jul 18, 2011

after the 5.6 update I started loosing the connection to my router. Having had issues with routers before I assumed that the router was on its way out. However I happended to have a laptop handy the other day and thought I would give it a try (after eth0 went down), router was fine(same cable too). I have tried bringing eth0 up/down (gui and ifdown/ifup) and restarted the network(gui and cli) but it will not get an ip(as I recall it does recognize that the cable is connected). If I do a reboot, eth0 comes up immediately. The log just shows repeated dhcp requests. I tried a dhclient -r but it errors out with no link found. It has been doing this since 5.6 came out (roughly once a day) so I THINK that it is not a hardware issue(should have died completely by now if it was). PSU voltages show stable and unchanged. It does use the forcedeath driver. 5.6-64bit fully updated.

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 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
The G4
eth0 - Public IP for ssh
eth1 - Private IP

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).

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:


eth0 Link encap:Ethernet HWaddr 00:1f:16:ba:4c:8c

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:

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 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 :: 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
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 :: B43 Inactive When Computer Shut Down And Restarted

Feb 22, 2011

I have v 10.10 and I had to hook up with ethernet cord to download and activate both broadcom b43 and sta drivers. Once they were both downloaded and activated my wireless worked fine. (Also I have an hp mini 210-1000 if that helps.) After unplugging my laptop and using it, if it dies or if things are running really funky and it seems like it could use a restart, or on one of the many occasions where I am not going to be using it for a few days and just shut it down, as soon as I start it back up.

I find that sta driver still says activated under system - admin - additional drivers, however the b43 now says inactive, and my wireless wont connect to any router, even though it can detect them, until I connect with the ethernet cord and redo the whole driver activation for both, and then restart. This happens every time, and although I don't often take my laptop out of my room, my router is away from my desk, so this is a major inconvenience when i have work to do, or if I were to ever take it out somewhere with me.
