Software :: Ethernet Interface Not Found

Jul 18, 2011

I booted an OS from live disk. The OS boots successfully but eth0 fails to start. I checked lspci , it outputs the exact ethernet card details :(Broadcom Netextreme II BCM5716 Gigabyte ethernet)

Ifconfig -a returns only loop back interface lo and sit0. The output of dmesg | grep -i 'eth' is :"Netfront : initializing network ethernet driver"

I was also able to find the kernel module bnx2.ko. I did insmod and lsmod lists it. I am not sure what exactly is the issue or how to debug this problem. Any assistance or pointer will be helpful. Thanks for your time.

General :: Ethernet Interface Not Found - Eth0

Jul 19, 2011

I booted an OS from a live CD. The OS boots successfully but eth0 fails to start. I checked lspci, it outputs these Ethernet card details:

ifconfig -a returns only the loopback interfaces lo and sit0. The output of dmesg | grep -I 'eth' is:

Ubuntu Networking :: Activate Wireless Drivers With No Ethernet Connection?

Sep 26, 2010

I'm been wanting to try Ubuntu for a while now, and when my mom's netbook started to get insanely slow with WinXP, I tried the Netbook Remix on a USB stick. I LOVE it, except I am unable to get the wireless working, which is the only thing stopping me right now from a full install.

I believe my problem is that I need to activate the two drivers "Broadcom B43 wireless driver" and "Broadcom STA wireless driver" which appear as unactivated when I go into the hardware drivers admin tools. Unfortunately this netbook (HP Mini Netbook FW376UA) does not have an Ethernet port, so I can't just temporarily hard wire it to activate these drivers.

So my main questions are: 1) How can I activate those drivers without an internet connection?, and 2) Do you think that activating these drivers is indeed the answer to getting the wireless working?

The details:
Machine: HP Mini Netbook FW376UA
Network Controller: Broadcom Corporation BCM4312 802.11b/g
Ubuntu version: Ubuntu 10.04 Netbook

I've a server with two NIC. Sometimes the server becomes unreacheable. When this happens, I did a reboot and then it works.. but when looking at the interface status (with ifconfig command), I've notice several "errors".So, I've tried to change NIC.. but the problem occurs again.I've also changed the port on the switch.

Ubuntu Networking :: PC Router Between Wireless And Ethernet Interface

Sep 2, 2010

I tried to setup a connection as below but face some problem (probably route table setting incorrect). Hope if anyone could shed the light.Basically, I have a PC1 (.1) and PC2 (.130) connected via a PC router. PC router has 2 interfaces: wireless (.2) and ethernet (.129). PC1 connects to PC router via LAN cable/wireless interface, while PC2 connects to PC router via cable. This settings try to simulate 1 wireless connection along the path (and because PC2 is too old to support wireless interface, we need a PC router). These interfaces are all under same 172.16.130.x subnet.

Ubuntu Networking :: Create 'Ethernet-over-IP'(or Tunnel) Interface?

Nov 28, 2010

I'm trying to create EoIP interface on ubuntu so i can create a simple tunnel to my mikrotik router. Is there anyone know how or even done that? If EoIP is not possible, is there any other simple way?

I had already read and thought about doing it with OpenVPN, but when I read the community documentation for OpenVPN on ubuntu 10.10, I fear it won't connect the tunnel to mikrotik OpenVPN server, since OpenVPN on ubuntu uses 2 certificate and 2 key files(as i read on the docs), but mikrotik configuration, i can see only 1 certificate can be applied on. This confuses me and make me decide to use EoIP(but i can't find any tutorial/docs about it). I don't actually need the encryption and security, i just need to create a tunnel for ubuntu and mikrotik.

Ubuntu Networking :: Persistent Ethernet Interface Naming

May 26, 2011

I'm running Ubuntu 11.04 on my desktop and the 70-persistent-net.rules file seems to be ignored. The ethernet interfaces are randomly shuffled around on boot (i have 4 interfaces). The original one was configured to have a static IP address (eth0). Is there anything that prevents the /etc/udev/rules.d/70-persistent-net.rules from being applied/used?

Fedora Networking :: How To Rename Ethernet Interface

Jun 20, 2011

I'm just installed Fedora 14 64-bits into a server which come with Multiple network interfaces, I'm found that the naming of each network interface is not in sequences in what I'm thought (e.g: the on board network interfaces name as Eth5 and Eth6, the additional card ethernet port name from Eth0 - Eth1 and etc). How to name the interfaces as what I wish to? What should I install to allow me to rename the interfaces.

Networking :: Fedora 14 - Ethernet Interface Does Not Get Activated Upon Reboot?

Nov 19, 2010

I have installed Fedora 14 about 4 days ago. I have set all the networking parameters like dns path, hostname etc. I have also ensured that I select the check-box for "Enable automatically when system starts" for eth0 interface. But weirdly, whenever I boot my system(or restart), I see that the interface eth0 is disabled. I have to manually enter as root and enable it, each time I boot/reboot my system. Why is this happening? Could you please suggest a way so that I have eth0 interface enabled always when I boot up?Also, my domainname also is not boot-persistent. What steps should I take to ensure that the domainname set once persists across reboots?

Fedora Networking :: FC11 Not Auto Detecting Ethernet Interface

Jun 10, 2009

On FC10, when system boots up, it would auto detect (from DHCP) and configure eth0.

This does not happen on FC11, but I can manually configure the interface. The entries in /etc/sysconfig/network-scripts/ifcfg-eth0 are identical on both OS releases.

Don't know if this is related, but when I run System->Administration->Bootloader, it fails system-config-boot - missing module kudzu.

Networking :: Bonded Ethernet Interface Can Ping Internally But Not Externally

Oct 14, 2009

So I keep reading that bonding ethernet devices is supposed to be easy. I have followed several tutorials and tried a few things on my own, and I can't seem to get it right. I currently have a setup that allows me to ping internally on my network, but when I try to ping externally I get the error:

Networking :: Ethernet Interface Leaves RUNNING State After Some Time

Jul 29, 2011

I am using RHEL6 on a server with 3 interfaces.

eth0 is connecting via a Cisco switch to the outer world and eth1 and eth2 to internal networks.

eth1 and eth2 are working without problems all the time, however I have the following incident with eth0: although it is RUNNING, and after it works for some time (like some hours), it then becomes incapable of sending/receiving traffic. Here are more details, after the interface exits the RUNNING state:

[root@mgt ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr E4:1F:13:6C:87:74
inet addr:9.162.91.26 Bcast:9.162.91.255 Mask:255.255.255.0
inet6 addr: fe80::e61f:13ff:fe6c:8774/64 Scope:Link
UP BROADCAST MULTICAST MTU:1500 Metric:1

[Code]....

I am wondering whether there this is because there is not traffic for some time and so the interface goes to idle. Is there any parameter I can tweak in RHEL6 to force the interface to remain RUNNING even in the absence of traffic (although I would be expecting that some 802.1 packets would be periodically flowing from the switch to the interface)?

Networking :: DHCPDECLINE Of Ipaddress From Mac Via Interface Not Found

Oct 15, 2010

My windows XP computer cannot get an IP address from the Ubuntu 10.04 DHCP server. It is configured on the DHCP server to receive a static address outside the main DHCP pool.

Partial config:

Quote:

subnet 192.168.168.0 netmask 255.255.255.0 {
pool {
failover peer "dc02";
range 192.168.168.1 192.168.168.164;

[code]....

The Windows machine seems to think there is already another computer on the network with 192.168.168.178, but it's wrong: there is no such address on the network.

Ubuntu Networking :: Unable To Activate Broadcom STA Wireless Driver?

Feb 4, 2010

I am using Linux Mint 8 Helena x64 Edition on Dell Studio 15 laptop which has Dell 1520 Wireless-N Mini Card. It does work when I boot from Live CD of Helena, connect to a wired network and download & install the proprietary drivers when prompted. But on the installed system, I am unable to activate the Broadcom STA driver. I tried completely removing and then reinstalling bcmwl-kernel-source and dkms packages from package manager.When I go to Administration -> Hardware Drivers and click on Activate for Broadcom driver, at first there used to be a window which said Downloading and it used to go away after few seconds and nothing used to happen. Then I installed few updates. At the time of writing, I have installed all the available updates. Now after clicking on Activate, I get this error :

Code:
Sorry, installation of this driver failed.
Please have a look at the log file for detains: /var/log/jockey.log

Ubuntu Networking :: Unable To Activate Wireless ( Sta Driver Broken )?

Jul 29, 2011

for over at week i have been trying to get my wireless card to work now. If i open Additional drivers, the non proprietary driver seems to be working and active. If i deactivate that and use the STA driver instead, it says active, but currently not in use. When i use the non proprietary driver, i can check mark on 'activate wireless', but nothing happens. When i use the STA driver there are no wireless options. I'm not sure if its important, but when i do "sudo lshw -C network" when the STA driver is active but not in use, the network status changes from 'disabled' to 'unclaimed'. When i came here, i tried to install "firmware-b43-lpphy-installer" as the sticky said i should, but the installation fails. It says my card is not supported: "Not supported card here (PCI id 14e4:4727)!"

Ubuntu Servers :: 9.10 2nd Ethernet PCIe Adapter Found Then Not Found?

Jan 24, 2010

During install of 9.10 server, both ethernet adapters were found. One is built-in to the motherboard, the second is on a PCIe slot. Selected the on-board adapter for eth0 during install, set fixed IP on the web, connected, updated, etc. w/ no problems. The second adapter is for the LAN.BUT, on first and subsequent reboots after installation complete the second adapter is not detected at all, as if it were not even plugged into the PCI or the driver not loaded. This happens on either of two slots, with two different adapters, Intel or Netgear, both pretty recent, and both of which are detected and work in a different box. 'Ethtool eth1' says device not found.This is a fairly recent motherboard 3N78EM).Since the adapter was found during installation I'm assuming that the problem is not with not the board. I've built several server systems with two or three ethernet adapters and have never run into this situation.

This was initially with 11.04, so I've decided to get back to 10.04, but the problem persists. Then, here we go with details:

networking checked - is enabled.
Ip configuration (I've got static local address) - is ok.
Ifconfig - recognizes eth0.
Iwconfig - recognizes wlan0.
Ping - 100% packet loss, always.
dig - goes on timeout.
netstat -an - doesn't show any connection with external address.
