Ubuntu Networking :: ADDRCONF(NETDEV_UP): Eth0: Link Is Not Ready
Apr 22, 2010
My installation has stopped detecting my wired network. Another computer connects fine with the same cable to the same access point. As far as I can tell it is simply behaving as if there was no network available from that cable but obviously there is. It was working a couple of hours ago, and I didn't install or uninstall anything, just shut down and booted up again.
LAN is enabled in the BIOS ifconfig does display eth0 ifup eth0 returns "Ignoring unknown interface eth0=eth0" in the output from dmesg:
"ADDRCONF(NETDEV_UP): eth0: link is not ready"
network appears in lshw and is not listed as disabled

The past couple days I've been attempting to use ndiswrapper to connect to my home network wirelessly and have run into a slight problem. I'm able to install ndiswrapper (of course), and install the driver. ndiswrapper -l comes up good, showing the driver is in place for my netgear wg311v3 card.
modprobe ndiswrapper I am able to get to work without errors, except, when i type ndiswrapper -ma it writes another file to /etc/modeprobe.d/ndiswrapper causing the deprecation error.
The card scans for networks, and I'm able type in my encryption key.
However it doesn't connect. | grep comes up with the error that the wlan0 link is not ready.
I think I've also been able to determine that the configuration I've put in to the card through the network manager is not actually configured.
Anyone know how I could possibly connect with the card.. It seems it should be able to work. alias wlano is also in place.

I added an init script numbered just before bind9 starts, which needs to see the ipv6 link-local address on eth0. Sometimes this address is not configured, yet. In all cases it eventually is configured.
I am unable to find any script that is configuring the ipv6 link-local address (which is in part based on the MAC address). Does anyone know if there is some script or program that is supposed to be doing this, or is it an internal kernel function?
One workaround I am considering is making this init script go into a loop around sleep 1 to keep checking for the ipv6 address. But I'm concerned this might cause some problems. Any suggestions? I don't want to let it move on to start bind9 until the configuration this script does (more ipv6 addresses) is done.
This is on Ubuntu 9.10 server (for which there is not a prefix choice).

I am trying to run Firestarter firewall but keep getting the message ETH0 is not ready. This problem has been highlighted by others but is there a simple way of sorting this out, answers in other forums are wide and varied. but it's not clear if they have been successful.

I recently set up a Debian-based gateway+router on a remote site. I've installed OpenVPN and made a VPN bridge to another network (that server is also Debian). The main network has all the resources and also a VoIP server (asterisk). Bridge seems to work fine, except that every time a Linksys phone is used to call - after a few seconds I get:
Jul 20 12:16:05 sklad kernel: [403987.817695] eth0: link down
Jul 20 12:16:05 sklad kernel: [403987.817939] br0: port 1(eth0) entering disabled state
Jul 20 12:16:07 sklad kernel: [403990.113701] eth0: link up, 100Mbps, full-duplex, lpa 0x4DE1
[Code]....
So whenever the phone is used, network falls down for a few seconds. And of course this breaks the call. There is also another Linksys box (analog-to-voip) and it works fine most of the time. However sometimes this "eth0 link down" happens too. There is nothing more in syslog to analyze, so I don't know where to dig. Physical device of eth0 is D-link DFE520.

In Slackware current there's a problem where iptraf does not show eth0. Here's a link to the bug report and patch.

I've had this show on 2 different current PCs. Kernels 2.6.35.10 and 2.6.35.7. This is with an Atheros AR8121/AR8113/AR8114, and Realtek RTL8111/8168B.

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?

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).

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

I have a problem where I'm using Ubuntu linux to mount a Windows Vista machine's USB drive and access it on the web using Apache. I did have the USB drive plugged into the Linux machine directly and that was working via the web. FollowSymLinks is on in httpd.conf
[Code]....
The mount works and I can see the files (see above) from my regular linux user account. If I make a test file in /mnt and soft link to that, I can see it on the web. So it's just the mount to the vista machine that seems to be a problem. It's supposed to be a simple read-only mount and the apache login should (I think) be able to see the same generic root access permissions.
log from apache: [Mon Apr 26 20:39:42 2010] [error] [client 99.99.99.99] Symbolic link not allowed or link target not accessible: /home/user1/pub_html/Music, referer: https://xx.xx.xx/~user1/music.html
The credentials have a login and password that matches a special read-only account on Vista. I can see the files on the system from Linux, but not via the web. As mentioned above, a different link to the same /mnt area works fine via the web. I've tried several different mount options with no success.

I'm trying to start a service that depends on networking being started, whenever the computer is rebooted. Is this easily possible from an /etc/init.d script? I have tried creating a script here (conforming to the standards), but I'm really doubtful that it's even running on boot, let alone working. When I test it manually, it works.How can I make a script that runs on boot which runs after networking has been started?

I've tried to install Linux systems have been failures. Trying to make this work, trying to get on the right wagon, and it's frustrating as all get-out.
Installed netbook remix onto a HP Mini 1000 (1116NR?) and everything seems to be working alright, except no wireless networking. I tried a couple of things and now it shows "device not ready" instead of "disabled", so I figure I'm getting somewhere.
The device is:
Broadcom Corporation BCM4312 802.11b/g (rev 01)
I want in. This is my 3rd try over the years of running Linux and I always hit snags like this that I can't fix because I've never gotten to play with it enough to learn what I'm doing and generally don't have a 2nd computer like I do right now.

All I want to do is share my internet connection that comes through the eth0 cable to my wlan0 wiki card. Firestarter seems the convenient tool for doing this. BUT it keeps telling me wlan0 not ready. The card is connected correctly and network-manager does see incoming signals.

I just recently installed ubuntu, my first experience with linux. I don't know if it isn't recognizing my wireless card or if it is another issue, but I am unable to view any wireless networks/connect to any. When I click on the network icon it says "wireless" with Device Not Ready underneath.

I just installed Ubuntu 10.04 and I can't seem to get the wireless connection to function. Ubuntu either says that the card is turned off or if I toggle the wireless switch on my keyboard it then says 'device not ready.' I'm using a Dell Wireless 1397 WLAN Mini-Card, and it works fine when I boot in Windows 7.

I thought I'd give Ubuntu 11.04 (Natty Narwhal??) a try on an old Dell Latitude D600 I had lying around. Install went great. Everything seems to run nice and slick.. except one thing.. the wireless is giving me the old "Device not ready (firmware missing)" So I can only use my lappy on a leash.
It's a pretty common Broadcom NIC... and I've tried running the System / Administration / Additional Drivers and nothing comes up.
It seems to me I need a driver someplace...I don't know where or how to get it installed.

This morning I installed Fedora 14 on my laptop. During the setup, I was able to configure the wireless connection and use it to install additional software from the FreshRPMs and Livna repos. When the install was completed, I was surprised to find the wireless not working. When I click on the NetworkManager icon at the bottom right corner, I see "Wireless Networks" Under that it says "device not ready" and it is greyed out so it cannot be click on.
Running lspci -vnn returned

Kernel driver in use: ath5k

I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.
