OpenSUSE Network :: Strange Ifconfig Statistics For Eth0 With 2.6.37.2-1-desktop Kernel?
Feb 28, 2011
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 :
Code:
grzes@opensuse:~> Linux opensuse.local 2.6.37.2-1-desktop #1 SMP PREEMPT 2011-02-25 19:59:41 +0100 i686 i686 i386 GNU/Linux
The hardware and drivers I'm using :
Code:
02:00.0 Network controller [0280]: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01)

I 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?

A network client computer gets ip address from dhcp server, loads initrd and failed on Loading Istallation System stage 4 or 5. If I try to continue installation in manual mode I get an error net_activate: ifconfig eth0 up failed I tryed network cards from different vendors it did not help. Ubuntu linux installs successfully in current environment.

I have a problem with the network. Worth two network cards and Ian wan. Do not take the ip. When the system boots not included until you do the command ifconfig eth0 up. 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.

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.

Installed a TP-Link TG-3269 Gigabit card in a machine running OS 11.3 32 bit, when I go into Yast, Network Devices, Network to try configuring the card I get this errormsg: 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. Couldn't find any mention of the card in dmesg's output, (though the 8139 onboard card is in there) there is some stuff about pci host bridge but I don't know whether they would be relevant or not
The chip on the card says it's rtl8169sc but lspci lists it as being 00:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8369 (rev 10) Done some googling and there don't seem be any drivers for a Realtek 8639 and it returns no matches from a search on realtek's site, but there is a driver there for rtl8169sc chips, which I downloaded and installed, no errors when installing it Even after a reboot I still get the same error in Yast's Network Settings screen, lspci still lists it as 8369 and the device isn't listed at all if I run ifconfig

I cannot seem to create a tun device using ifconfig, even though the module is loaded, and the node tun is present in /dev/net and appears to have correct access permissions, trying to use nstx which requires the tun device. Only thing I can think of is adding an alias, but not sure where, since there is no /etc/modprobe.conf or /etc/modules.conf in SUSE 11.3.

I have created my own distribution with susestudio.com , based on jeOS template and it works well But I have some problems with network configuration. I make a default configuration with susestudio ( configuration -> General -> network ) and I put for example 172.16.0.185 address. I also put a script which configures IP address with different informations coming from for example a serial port to make my own IP address. This script make the new address and call the ifconfig system program. For example, the script calls "ifconfig eth0 172.16.0.182". And now, I can ping the two addresses, 172.16.0.185 and 172.16.0.182. Is this normal ? I thought the new command "ifconfig eth0 172.16.0.182" would overwrite the old value ( 172.16.0.185 ). It works as this on other distribs ( like ubuntu ) but not on opensuse.
I know that I can have 2 addresses but using the following syntax : "ifconfig eth0:1 A.B.C.D" (if kernel supports aliases ) , and I don't know if it is normally possible to have 2 address from the same subnet. How can I overwrite the default config , and not to have the first address available ?

I'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:
htpc:~$ ifconfig

Interrupt:23 Base address:0xe000
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.

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:
proc fs indicates 43:
sys fs indicates 43:
Relevant part of lspci -vv output for irq 17 (this belongs to wlan0 and not to eth0):

I have a laptop running 11.2 with an internal Broadcom-based Wi-Fi card that's working fine. I'm trying to get 802.11n going with the WUSB600N. The USB ID on this device is 1737:0079. I believe this means it's a "V2" with an RT3572 chip.
No driver loads for this device when it's plugged in. If I do a "modprobe rt2870sta", a driver loads, and syslog shows "rtusb init" and "usbcore: registered new interface driver rt2870". But ifconfig -a doesn't show a new network interface. I've also tried building the RT3572 driver from the manufacturer's web site. It builds fine, and modprobe will load it, but I get the same results as the rt2870sta driver.

Yesterday I installed 11.4. First it did run very nice but now I am facing an odd problem: I am mounting on my new 11.4 box a folder via nfsv4 from an opensuse 11.2 server (updated to kernel 2.6.33.6).
I got some folders where the 11.4 cannot see files which are defenitely present on the server. They are completely invisible to the client! In one particular case I have eg. 108 files in the folder on the server, but the 11.4 box only sees 107. One is missing. It does not show up using ls and I also can't access it blindly using eg. cat. The file does not differ from all the others in that folder regarding permissions/ownership/acls etc. It is also not big (1728 bytes) nor is it a special file (link/socket etc.just a plain C header file). That single file is just not visible when mounting with nfsv4 on the 11.4 box. When mounting it with nfs3 instead the file is visible. But for obvious reasons I want to stick with nfsv4.
I restarted all nfs related daemons on both the server and the client a couple of times but it does not make any difference. I also cannot find any problems in any log files on the server or client up to now. I rebooted the client but not the server (I can't do that right now as it is in heavy production).
I do not see these problems with other opensuse boxes running 11.0/11.2 or 11.3 in my network. They can see/access these files quite nicely. This is really strange. Does any have a clue what is going on here or how I can narrow that problem down?

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?

I'm new to this forum site and I was wondering how can I bridge a network between the eth0 and wlan0 connections?my eth0 NIC is a RealTek RTL8111B 10/100/1000 Ethernet Card (OnBoard) and my wlan0 NIC is a RealTek RTL8187B 802.11b/g WiFi USB Adapter Card.Are there any utilities, such as bridge-utils that I can use, except for Firestarter since Firestarter states that the eth0 connection is not established, or do I right-click on the network icon and select Edit Connections and go to Auto eth0 and under the IPv4 Address setting and select Shared to other computers and run a live connection there?The main reason is that I need an Internet connection for my Xbox 360, which is connected to my Linksys WRT54G 802.11b/g Wireless Router, that has DD-WRT firmware installed and 4 WiFi hotspots for any wireless device, such as my PSP, DS, DS Lite, Wii, Laptop(s), my brother's PC (needs a WiFi card), and my dad's PC (needs either a WiFi card or an Internet connection from my brother's computer to my dad's PC)

I have the following strange thing with a RHEL4 installation. Since last week, the system did a reboot and now something is really fucked up. During boot we get the following messages (don't care about 'strange' typo's, my colleague typed it 'blind' from the screen)
Code:
The strange thing is that we never see a 'could not mount blabla' or similar messages. First we thought it was a failing kernel update by plesk, but even after manually updating the kernel with RHN RPM's, still the same message. Booting with rescue mode and then chroot the system works. After that we even can start things like plesk and so on.
We double checked things with another RHEL4 install, and at least two things were odd:
1: the working machine has /dev/dm-0 and /dev/dm-1, the broken one doesn't
2: some files on /dev didn't have group root, but 252
We tried to recreate the /dev/dm-X nodes with [vgmknodes -v], output:
Code:
A fdisk /dev/sda shows: /dev/sda2 XX XXX XXXXX Linux LVM (I removed the numbers because this line is from another machine, but rest was identical)
We have a copy of the boot partition so if one need more info please let me know.

explain the difference between these two commands. I'm currently reading about changing your mac address and both of these commands show up a lot. They sound like the same thing to me. Is one better than the other, or do you need to use both to change your mac address?
Code:
sudo ifconfig eth0 down
sudo /etc/init.d/networking stop

I tried to update my fully-working 64-bit 11.1 system to 11.2. I used the network install and chose the Update option. It took a few hours so I didn't sit through the entire installation but when I returned the 11.2 login screen was displayed. Having logged in, however, I found that I couldn't access the network.The boot log showed that network had failed to start. "ifconfig" lists only the "lo" interface. "ifstatus eth0" returns "Interface eth0 is not available"
Network Settings in YaST lists 2 entries in the Overview tab. The first entry has Name:"NetXtreme BCM5755 Gigabit Ethernet PCI Express" and IP Address: "Not configured".The detail pane for this entry shows "NetXtreme BCM5755 Gigabit Ethernet PCI Express (Not connected) BusID:0000:3f00.0 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". The Edit and Delete buttons are both disabled for this entry.
The second entry has exactly the same name as the first with the IP Address listed as "DHCP4". I assume this was the entry that was carried over from the 11.1 system. The detail pane for this entry shows "NetXtreme BCM5755 Gigabit Ethernet PCI Express (No hwinfo) Device Name: eth0. Started automatically at boot. IP address assigned using DHCP4". The Edit and Delete buttons are both enabled for this entry.lspci reports "3f:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 02)"
lsmod lists only "edd", "loop", "sr_mod", "sg", "cdrom" and "dm_mod".
The files in /etc/sysconfig/network/ are "if-down.d/", "if-up.d/", "providers/", "scripts/", "config", "dhcp", "ifcfg-eth0", "ifcfg-lo", "ifcfg.template", "ifroute-lo",

My eth0 is not up everytime at boot up. I will need to <service network restart> to get it up.
I have used yast's /etc/sysconfig editor to set /etc/sysconfig/network/config -> MANDATORY_DEVICES to eth0
And I have also added <alias eth0 e1000e> to /etc/modprobe.conf.local
And also set eth0 device to activate device at boot time using Network Card Setup.
But eth0 is still not starting up at boot time. What should I do to get it up at boot time?
I'm using openSUSE 10.3. And no, I'm am unable to move to 11.2

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:
lo ...
Waiting for mandatory devices: eth0 __NCS__
29 28 27 ... 1 0 ... failed
eth0 no interface found ... failed
[code].....
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 want to set my desktop IP address to always be 192.168.1.2. The NetworkManager connects to the network automatically and the IP address is assigned randomly. I can set up another connection in NetworkManager and always change over. But is there any way to make the default eth0 interface to be permanently set to a certain address (using NetworkManager, not ifup)?
