But now it has vanished and i donno when. i tried ifconfig eth0 up but no use. The result of cat /etc/network/interfaces is as follows
auto lo
iface lo inet loopback
just install opensuse today, but my system can not found eth0, ifconfig ,just have not eh0 infomation,only got lo infomation,
View 1 Replies View RelatedI'm trying to get my Ubunutu and OSX systems to connected via a cat5 cable to transfer some large files around very quickly. Now i know normally this would require a crossover cable as it's a direct connection but the macbook/OSX can handle changing the wires round to make it work like a crossover cable as I've done it before. However the macbook creates a self-assigned IP or as I've tried I've set it to :
IP:10.10.0.1
Subnet: 255.255.255.0
Then I've setup the Ubuntu system both through the System>Admin>Network panel as:
IP:10.10.0.2
Subnet: 255.255.255.0
and my /etc/network/interfaces file is the same;
#lines added to get static crossover cable working
auto lo
iface eth0 inet static
address 10.10.0.2
netmask 255.255.255.0
Yet when I run ifconfig in the terminal eth0 isn't present
Code:

Also even when I try and ping 10.10.0.2 either from my OS X or the actually Ubunutu machine all I get is:
Code:
ping 10.10.0.1
PING 10.10.0.1 (10.10.0.1): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
Yet the Ubunutu machine is also connected to Wifi and when I ping it's own address I get the expected response. To me it just seems like eth0 isn't being recognised somwhere or it's not turned on yet I can't seem to find any toggles or settings for it anywhere. Further more if I check >System>Admin>Network Tools the IP for eth0 is 0.0.0.0. What could be going wrong and why no IP set correctly?
I've got a vmware install of Fedora 12 running as a server. This install has the /etc/sysconfig/network-scripts/ifcfg-eth0 file configured with the proper info and the service has been restarted. When I run ifconfig I only get the loopback interface, when I run ifconfig -a I can get the eth0, but without the pre-configured ip address. When I enter ifconfig eth0 up I can activate the interface, but without the afore mentioned ip address. I need to be able to yum ssh, install it, and run it with rsa keys. Can do none of this without an interface obviously.

Code:
sudo ifconfig eth0 down
sudo /etc/init.d/networking stop

The network card is connected to a router, he does not see it. Router working, tested. Network card is working well, tested on Windows. RX RT packages go, withheld support for ipv6 and packages no longer go.
View 14 Replies View RelatedI have been noticing a trend on boxes running 11.4 getting RX dropped packets where prior to 11.4 they did not get them. Basically every box running 11.4 now logs dropped RX packets. Have tried changing cables, and in one case replaced the NIC with a different brand (and driver) nic. Also played with receive buffers and yet the counters still increment. In addition to OpenSUSE, I run several operating systems to include Centos, Scientific Linux, Debian, OpenIndiana, HP-UX, VMS and so forth. So far this anomaly has only shown up on machines running OpenSUSE 11.4. Any one else noticing this on your OS 11.4 machines? If so, were you able to resolve?

When using the Ubuntu 10.04 Live CD I had no problem connecting through my wired network connection. After installation all I can find is the Wireless connection.
I have a Toshiba Satellite A70 laptop. A check of the system shows no eth0 available. What do I need to do to get the wired connection back again?
Also, if the wired worked before installation, why doesn't it work afterwards?
The computer and system in question is the laptop from my description and openSUSE 11.3 with a different kernel from this repository :[URL]..free to move this thread if it should reside in the beta/prerelease forums section. The IMHO relevant information about my hardware and system is shown below.
The kernel I'm using :

On my system (OpenSUSE 11.4 - kernel 2.6.37) ifconfig indicates different interrupt number for eth0 than proc aqd sys file system.
ifconfig indicates 17:

On my machine (Desktop PC) I have 2 network card : wireless (rt61 802.11) and a wired card (BCM44). When I install debian 5.
The wired card is detected and logical name eth0 is assigned, while wireless is not assigned I install firmeware* software to configure the card. It is done in some way ( I used mnetwork from mepis, it works fine).
Now the problem: eth0 disapears, and no eth0 inteface found? ifconfig gives just wlan0.
Question: Why there is no eth0, it was before configuration of wlan0 ?
How to active again eth0, or ho to create the logical eth0?
i know this is crazy, but im using a [URL] and have loaded a copy of "red hat linux 7" on the computer. i have no idea what kind of hardware config/spec stuff i should have in my immediate vision, and if i did i'm not sure how i would make sense of it all. linux loaded fine. didnt save drivers. eth0 not showing in ifconfig report, but lo is connecting to network, other host cannot ping linux and vice versus
can mount a cdrom, but not a usb flash dont quite understand how the load methods work involving /mnt/cdrom/"usbutils-0.86tar.gz" eth0 problems and gnome rpm stupidity keeps me from upgrading sys from old version to a newer version, cant even find the cmd to show me that info, sorry. have usb files i want to mount, dont know how to loAD THE CDROM FOLES, SO EVEN THAT ISNT WORKING OUT HAVE DISCS WITH howtos just need to stay focused on steps to get desired end result, while trying to learn too much info for what im currently doing between all the f!@#@ing windows i have open.
i have a problem. I cant find anything except my mac address if i type "ifconfig eth0" in terminal.There is no gateway adress ip adress and netmask. This is wierd. How can i asssign those to a eth0?

When I try execute a variety of basic commands (including ps, ls, ifconfig, locate), I receive the error 'no such file or directory'.
Here are some suggestions that I've found online, that I have tried without success: I did a 'whereis ps' and found the file in the /bin/, and have checked that '/bin' appears when I do 'echo $PATH' I did a filesystem check which showed my hard drive as being clean I tried doing a 'sudo chmod 777 ps' but was told that I dont have permission. I don't think permissions for these files would have changed though (and I can't check as I can't run the 'ls' command).

View 2 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'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.
