Networking :: Eth0 Works Great - Eth1 Not Working ?

May 14, 2010

Ok, so eth0 is up and working great. eth1, however, comes up with a link light, however the packet counters in ifconfig remain at 0. Appears that eth1 isn't working.

Here's my setup:

-Dell latitude CPi laptop with 2 PCMCIA network cards and no built-in ethernet.
-Slackware v11
-eth0 is connected inside my router on my 192 network. Static address with good connectivity
-eth1 is connected on the other side of my router in promiscuous mode in order to listen to the traffic coming into my network.

Troubleshooting so far: I have switched the pcmcia cards between slots and regardless of which card is in eth0 or eth1, eth0 works and eth1 does not. I have also switched the card dongle between cards as well as the ethernet cabling between the cards. With any of the combinations eth0 works like a champ but eth1 does not, so I think I've ruled out hardware problems.

Networking :: Eth0 Does Not Work After Shutdown/start But Works When Restart

Sep 13, 2010

When I shutdown computer and start it up, eth0 doesn't seem to show up (though lspci sees ethernet card and modules are loaded). When i reboot (which is exactly the same, in my opinion), it works good. I'm using Sabayon GNU/Linux, Gnome Network Manager applet.

Linux 2.6.34-sabayon x86_64

Ubuntu Networking :: No Eth0 Found After Installation From Live CD?

Aug 21, 2010

I tried searching but received hundreds of unrelated posts.

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?

Per the HowTo post a Wireless Issue Sticky, I have included the information in the 10 steps below.Here is the description of my problem: I am getting back into Linux after purchasing a new PC (have not owned one personally for several months). I purchased an HP, as I've had personal success with them. It is an HP Pavilion g4 Notebook.When I booted the Live CD, I was pleased that wireless just worked.However, after installing, wireless does not work.The Additional Drivers Tool appears to recognize my wireless card;however, when I attempt to active the driver, I receive an "installation failed" dialog.ere are two screenshots:And here are the results of the file from the second screenshot:

CentOS 5 Networking :: Wireless Works On LiveCD But Not When Installed

May 23, 2010

I've been using Linux for about 2 years now, mostly Ubuntu & derivatives, but I've also tried Fedora, Mandriva, and others. I wanted to give CentOS a try because I'm very interested in going for a Linux+ or similar certification, and so I'm looking to start learning how to configure & maintain Linux servers and so on. I have a friend who's a Linux sysadmin, and he recommended CentOS as a good learning tool.

Anyway, I've only got a wireless connection in my office at home (the actual cable modem is downstairs) so I intentionally chose a wireless adapter that would work with Linux -- it has a Realtek RLT8187 chip, for which there is support built into the kernel, or so I've read. It has worked out of the box in just about every distro I've tried, and indeed it worked OOTB when I tried out the CentOS 5.5 live CD.

However, when I actually installed the CentOS to my hard drive it no longer worked -- I have only a greyed out option for a wired connection (presumably since my motherboard has an ethernet adapter, but there is no connection). Why the wireless would work in the live session but not after install? Is there a firmware file or something I need to track down? I did look on this page, but it doesn't mention anything about RTL8187.

Ubuntu :: Eth0 Works Without Configuration - PC Doesn't Seem To Care About Anything

Mar 14, 2010

my internet connections works via my eth0 adapter. For Windows user this may be fine, but I actually would like to know what makes it connect. My /etc/network/interfaces shows:


No eth0 mentioned here. dhcp3/dhclient.conf consists only of commented-out lines, so no eth0 here either. In /etc/init.d I see there is this networking daemon. When I do


that magically enhanced eth0 works even if you want to shut it down. No wonder I don't get my wlan0 working, my PC doesn't seem to care about anything I am configuring here.

Networking :: Eth0 Fixed IP - Eth1 DHCP Gateway - Access To Eth0?

Aug 19, 2009

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 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?

Networking :: Production Server With Static IPs On Eth0 And Eth0:1 - Getting Private LAN On Eth1?

Jul 1, 2010

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
The G4
eth0 - Public IP for ssh
eth1 - Private IP

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).

Networking :: Ignoring The Unknown Interface Eth0=eth0?

Dec 18, 2010

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:


eth0 Link encap:Ethernet HWaddr 00:1f:16:ba:4c:8c
inet addr: Bcast: Mask:
inet6 addr: fe80::21f:16ff:feba:4c8c/64 Scope:Link

Hardware :: Eth0 Dead After Power Outage - Eth1 Works But No Connection

Oct 10, 2010

I setup a mythbuntu pc with an onboard card (eth0) so I could watch and listen to movies and music stored on my other pc in the basement. Everything worked fine until we had a power outage. I turned on the pc after the outage and had no networking.

I looked and saw no link lights. I verified the network port but plugging in a laptop. I got an ip and able to connect to the internet so the port is not the issue. I plugged in a pci 10/100 card (eth1) and booted up, got link lights, but no networking and not able to even ping the gateway. I setup a static ip in /etc/network/interfaces and added a route to the gateway/router. Still nothing.

Ubuntu :: 11.04 From The Live CD All Works Well And Pretty?

When ever I run Ubuntu 11.04 from the Live CD all works well and pretty. However, when ever I install it, my main monitor won't detect correctly and my second won't even display anything at all. Basically, Live CD runs perfect, Installation does not.

One other note: While running off the Live CD, there was no Unity. Running the actual installation, it is running Unity.. ?

Ubuntu Installation :: Live CD, Upgrade And Install Fail On 9.10 And 10.04 - 9.04 Works?

May 23, 2010

My first upgrade attempt to 9.10 ruined my install - there was no return and as 9.10 would not install either, I reinstalled 9.04 and everything was as expected.I decided to wait for 10.04 hoping the issue had been solved - unluckily it has NOT. Neither Live CD 9.10 nor 10.04 work. New Mint does not work either - to closely related to Ubuntu, but Suse live CD does. Played around with findings from different threads - like taking out "quiet splash --" and adding modprob parameter to no avail Prime suspect is HD and HD controller (ATA/PATA) - but I could not nail it.

Ubuntu Installation :: Live CD Works But No Display After Install / Solution For This?

Oct 10, 2010

I have this problem where the 10.10 LiveCD 64-bit works (as in I get full resolution display and no video issues at all). But after install, the OS boots successfully but there's no display. I know it's successful because I was able to login in the dark (sound works).

Here's what I have:
HP m9340f (NVIDIA GeForce 9500M GS with HDMI)
46" Sharp connected via HDMI
Windows 7, works fine.

Here's what I tried with no luck:
1. CTRL-ALT-F1 still doesn't show anything on screen, no terminal
2. Connected via VGA
3. Connected another 17" monitor via VGA, rebooted
4. Added vga=789 in grub before booting

The weird thing is that I had 10.04 before and it was working for a while then it suddenly stopped working. I figured I'd wait until 10.10 but I now have the same issue. I haven't tried 32-bit... I can give that a shot in a bit.

Ubuntu Installation :: System Freezes After Upgrade - No Live USB Works

Feb 5, 2011

I was running 10.04 with no problems. Upgraded. I may or may not have lost power before the upgrade was finished. Now my system locks out the keyboard and mouse on the login screen...nocapslock light or anything, but I know it's still running because the clock at the bottom increments once per minute. Booting safemode does not help, it simply hangs at some point on the scrolling black screen instead.I can boot 9.04, which is still installed on another partition, just fine.Is there any way I can boot to a terminal and try running apt-get again, to see if I can fix whatever's wrong?

Fedora Installation :: 12 Live/KDE: Only One Processor Core Works?

Mar 6, 2010

I wanted to try Fedora 12 Live/KDE on a newly-bought Fujitsu Esprimo P1500. Booting with no kernel options would just freeze the machine. After some random experimentation, I added the option "nolapic" and got a seemingly working machine. However, only seemingly, as it turned out that only one of the processor cores was working (the processor is a "Pentium(R) Dual-Core CPU E5300").

General ::Live USB That Works With Snow Leopard Macbook Pro From 2010 ?

Jan 24, 2011

I was searching for a long time for a Linux Live USB that I can boot my MacBook Pro from. Is there such a distro I can install on Snow Leopard or Windows 7? Update: I've found this:

"isohybrid" CD images (..) are special in that as well as the normal CD-based ISO9660 filesystem they also contain a valid-looking DOS-style partition table. Thus, if you simply copy one of these images raw to a USB stick a normal PC BIOS will boot the image directly. (...)Finally: I'd like to add support into xorriso for creating the nasty HFS hybrid images that are needed for booting Macs. The code that does this in cdrkit is probably some of the worst that I've ever worked with, and,I'd like to get away from it. If only Apple hadn't stupidly built their proprietary platform around this and had used open standards instead

Ubuntu Multimedia :: X-Server Works With LiveCD But Not On Installed 9.10

Jan 10, 2010

After a Christmas morning scramble trying to get Sims3 working for the kids, I ended up pulling an Nvidia 6200 AGP card out of a perfectly good Ubuntu box and threw it into the kids' PC. I replaced it in the Ubuntu system with an old Nvidia Geforce 2 Ti AGP. From the start I was unable to get any resolution higher than 800x600 with the GF2. Tried removing xserver-org, reinstalling, reconfiguring, etc. Installed the Nvidia legacy drivers, all no luck. Tried booting with a 9.10 live CD and it works perfectly - various resolutions, refreshes, etc. So, the card is capable. I've checked, rechecked, restored, modified xorg.conf to no success.

I'm at a text login now, startx returns (among other info) the following:
dlopen: /usr/lib/xorg/modules/drivers//nvidia_drv.so: undefined symbol: AllocateScreenPrivateIndex
(EE) Failed to load /usr/lib/xorg/modules/drivers//nvidia_drv.so
(EE) Failed to load module "nvidia" (loader failed, 7)
(EE) No drivers available
Fatal server error:
no screens found

Now, I've checked, and nvidia_drv.so is where it's supposed to be (in the drivers directory). What concerns me is the "//" in the directory path string in the (EE) above preceding the driver name - shouldn't this be a "/"? Is the command not able to find the driver correctly? Regardless, at this point my goal is simply to get the system to use whatever process the live cd is using which results in a working GUI. Don't need fancy 3d, etc, just want a working system.

Ubuntu :: Cannot Boot From Live CD With Installed

Feb 20, 2011

I have Ubuntu 10.10 fully installed on my laptop, I am trying to get my main drive partitioned so I can install windows as well, only problem is that I can't do that without using my live CD to unmount the drive. Heres the big problem, my CD just wont boot. when I try to boot from it nothing happens and my computer just starts up as normal as if there was no CD in the first place. I have set my CD drive as my main boot device in BIOS so I know thats not the problem, and I have also tried using an external USB drive to boot from with the same results. I used the same drives and CD to do the install just a few days ago so I'm fairly certain that they are not the problem. The only thing that I can think of that might be causing trouble is that when I installed I got a black screen on my first boot (caused by my nvidia drivers apparently)and had to edit my GRUB a little to fix it.
