I have a similar problem. My eth0 also disappeared after an upgrade to Ubuntu 10.04, and didn't come back after downgrading back to 9.10. The LEDs on my ethernet port are *not* flashing. Does this mean my network card is dead, or is there any hope I can get back online?

View 1 Replies View RelatedI have just upgraded a CentOS 5.2 box to Centos 5.3
I did have a bridged networking setup for Virtualbox which worked well. eth0 was bridged with br0. br0 boot protocol was DHCP and it sent its DHCP_HOSTNAME to the windows DHCP servers.
since the upgrade the br0 does not get an address but the eth0 does. I found that the scripts in /etc/sysconfig/network-scripts/ifcfg-* are getting rewritten.
I figure I may not need to have a bridge any more so I stripped that out to try to get a simple network setup working. I now just have eth0. I edited /etc/sysconfig/network-scripts/ifcfg-eth0 so that it looked like this,

I have a problem with my system. Fedora 12 64bit I was tinkering with enabling rawhide and upgrade firefox(3.6 / namoroka) and pidgin. Then I disabled repo. downgrade pidgin again with its dependencies (glib2 or was it glibc2). Long story short, the next time i boot up, there are a lot of error / FAILED. Boot into run level 3 is fine. But i cannot use yum and it give error regarding libglib.so or something and phython need it. Locate found those item, so it might be because the version is wrong because of those upgrade / downgrade process. Sorry if the problem isn't clear, but can anyone give direction what should i provide.

View 1 Replies View Related5.10 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 recently installed Fedora 10, having chosen that version in order to be able to use the packages created by the Planet CCRMA group for doing audio recording (they don't have F11 packages ready yet, AFAIK). Last weekend I got a prompt to upgrade my system, and I naively accepted it, not even realizing that it was an upgrade to F11.
The upgrade didn't work, for reasons that I still don't know (probably a video driver issue), but since I know the F10 installation worked, and Planet CCRMA is not up to F11 yet, I'd just like to downgrade myself back to F10.
Can I just re-install Fedora 10 from the DVD I used before, or will the F11 installation cause problems? I haven't really done any work that I mind losing, so I'm not too concerned about overwriting my previous installation.
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.

Last weekend I upgraded my Opensuse 11.1 machine (pretty clean) to 11.3. After the upgrade, the NVidia graphics no longer worked, but more importantly, eth0 was not bound to my Intel 82566DC gigabit ethernet controller. I fooled around in yast network devices long enough to know that everything there is configured correctly. The Yast message at the bottom of the Network Settings screen says:
"Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details."dmesg output shows nothing related to networking. The boot screen shows:
Setting up (localfs) network interfaces:

Any ideas here? I've googled till my fingers were tired and all I've found are references from folks with real hardware issues. This machine worked fine for me under 11.1. Now I can't get 11.3 to bind the nic.
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.

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:

How to active again eth0, or ho to create the logical eth0?

I'm about to add pci ethernet card. Currently the mobo nic is eth0. When I add the new card will it by definition be eth1 (or will it become eth0 and the mobo nic become eth1)? The broader question is: how are the "eth's" numbered at boot time? If I were to add a 2nd pci nic, could I predict which would be eth1 and which would be eth2 (based on pci slot number??)? Is there somewhere to readup on this to get a broader understanding?

I recently installed Lucid 10.04 on a P-IV desktop. The install went extremely smooth and Ubuntu was up and running. Hats off to the Ubuntu folks for the excellent user-friendly experience in the installation process. However , I have run into a networking issue. I connected my PC to the router issued by my ISP. This is a plug-n-play type of connection where the username/password settings are stored in the router and there is no configuration required in Ubuntu for accessing the internet. All I need to do is connect the router and my PC using the LAN cable. I was able to surf the net without any issues.
A few days later , this ISP service was down and hence I switched to another wired ISP. This ISP required me to dial a connection using another supplied router. I setup the connection using pppoeconf where I was asked to enter username/password. Again I was able to surf the internet without any issues. Next , I shutdown the system and before booting it , I switch back to my original ISP connection (the plug-n-play one). But now I am not able to connect to the internet. The router lights show that my PC is connected to it , but when I issue ping 192.168.1.1 to check connectivity with the router configuration, I get
Code:
$ ping 192.168.1.1
connect : Network is unreachable.
Also , issuing ifconfig does not show eth0.
NM-applet also does not appear in my notification panel at the top.
How I can go back to using my original plug-n-play ISP connection? I have read some posts about networking issues , but none quite like this one. Please note that all my Internet connections are Wired connections.
Here is my interfaces file
