CentOS 5 Networking :: Replacing The Kernel To The Non Xen Version If I Dont Have The Install CDs?
Jan 9, 2010
I have recently set up a CENTOS server using the kernel 2.6.18-164.el5xen (x64 5.4 Install I believe). Originally I set it up with Xen to becasue I was goig to create the odd VM on it, however I no longer need to do this.Further, I believe I am having networking issues due to the installation of Xen. The machine cannot seem to locate any network addresses (eg websites) unless I put in a hosts entry for them. I believe this networking issue would be easier to rectify if the virtual networking interfaces for Xen were not installed but to do this requires a Kernel replacement. Im not experienced with doing this and the machine is located remotely to me and I dont have the original install CD available.How would I go about replacing the kernel to the non Xen version if I dont have the install CDs?
i'm currently running centos 5 with kernel version 2.6.18-92.1.22.el5 is there any way to update to kernel version >= 2.6.27 via yum ? if not via yum is it advisable to compile from source?
I have just downloaded CentOS 5.3. The kernel version is 2.6.18.xx However, when I updated the kernel version has not changed. Still 2.6.18. Unless something went wrong with the updates. The most up to date kernel is 2.6.31.xx I was thinking shouldn't it update to this new kernel? On my Fedora 12 I have 2.6.31. However, I thought the kernel of 2.6.18 would have been updated as least a little.
I just ran "yum update" to download the latest kernel from the repository, and noticed that it's 2.6.18-164.11.1 while the latest on www.kernel.org is 2.6.32.4.Out of curiosity, why is there such a discripency between the two? Lack of resources to test and build binaries?
I want a new kernel RPM in my custom CentOS 5 kickstart distro. I built the kernel, got a nice kernel RPM out, and replaced it in my ks.cfg. The install goes fine until the very end, where Anaconda prints some spurious stuff about mkinitrd failing.I get why it might fail -the kernel version argument to mkinitrd was no doubt for the old kernel. But I have no idea where this is -it's not in the ks.cfg afaict, and so I don't quite get where Anaconda / mkinitrd gets it from.
I'd eventually like to use this kernel for the installer as well, but I think I understand that process much better.How do I tell kickstart / Anaconda / mkinitrd to use the new kernel version number?
it said the kernal requires an X86-64 CPU, but i only have a i686 CPU. what do i need to do to get the appropriate kernel. i am using windows xp now and want to move to linux. do i just need to try ubuntu or can i do something to change mine in windows now to go ahead and upload Zorin
I have been able to load CentOS on my computer. I have the motherboard DG41TY from Intel. It seems that the only problem I have is my network card does not work. On the Intel site there is a link to download the network driver for Linux. I did that. It's an rpm file. realtek-r8169-kmp-default-8.004.00_2.6.16.60_0.21-0.i586.rpm is the name. When i right click and say install it tried to connect to the internet for some thing and fails. of coarse it does there not loaded yet. I added a second nic that cent did recognize and got me online. I want to load the on board driver and remove the add on card. When I try to load now I get missing dependencys.
I am learning Device Driver programming. In the tutorial material they have mentioned to download "main-line� kernel. I have installed Ubantu 10.4. Now I want to install kernel in that. Which version of Kernel should be downloaded and installed for Ubantu 10.4?
A problematic system has this kernel: 2.6.35-22-generic #34-Ubuntu SMP Sun Oct 10 09:26:05 UTC 2010 x86_64 GNU/Linux
A working system has this kernel: 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux
Can I put the working kernel onto the problematic system? I've copying the contents of /boot from the working system (I did *not* copy the /boot/grub directory). Should I manually start editing grub.cfg for a dual kernel boot or is there a better way? The problematic issues are with video playback (choppy after upgrade) and video capture - you can only open the capture device once, then you have to reboot since upgrading.
I was trying to update the new nvidia drivers since they dont seem to work in the newer kernel, or to try to fix it but now when i run yum update I get a screen like this:
Downloading Packages: Running rpm_check_debug ERROR with rpm_check_debug vs depsolve: kernel-uname-r = 2.6.38.3-18.fc15.i686.PAE is needed by (installed) kmod-nvidia-2.6.38.3-18.fc15.i686.PAE-1:270.41.06-1.fc15.i686
i'm using this guide videos - howto: debian linux kernel compilation, part 1 and the author says i need kernel 2.6.26 this version of kernel doesnt longer exist in kernel.org website and the only 2.6.26 i found is a patch here. should i use the patch? or download another version of kernel?
Just over a year ago I did a main board processor and memory upgrade on my system. I was running Fedora seven i686. If I recall correctly I booted with the install disk and chose "repair existing system" or something like that. Then I typed "rpm -e --nodeps" which removed the existing kernels. Again going from memory I typed "yum install kernel" A new kernel was installed I rebooted and the system ran great.
I have been having sound problems that i can't resolve with Fedora 12 i686. The sound card drivers are not always loaded at bootup. I have posted here several times about this problem and i may have messed things up a bit with various attempts at repairing. I am wondering if removing and reinstalling the kernel as I did at the time of the upgrade might help.
Are the commands I listed correct? It's been a long time. I found the instructions on this forum but can't find them again.
Is there any legal way to install an older version of linux-kernel (say 2.6.35) on 11.04? By legal I mean - no source-compiling and third-party repo adding.
I am using OpenSUSE 11.4 64 bit with GNOME. I also use the Tumbleweed and Packman for Tumbleweed repositories. Accoording to uname -r, my current kernel version is 2.6.37.1-1.2-desktop.
How do I safely update to the latest stable kernel version?
I am new to OpenSUSE. Please provide step by step directions.
Is there a link to download a version of Suse with either kernel 2.6.26 or 2.6.28? For some reasons I have, I need one of these kernel versions. The newest download here, 2.6.37, won't work for me.
I am an openSuSE user for many years. My current installation is openSuSE 11.2. However, my first was SuSE 6.4 and I have been _constantly_ upgrading since then until reaching the current openSuSE 11.2. The technical issue I have been facing lately is with the kernel version of my current system: although it should be 2.6.31.5-0.1-desktop, as this is the one I have chosen via the online update mechanism and the yast2 system boot-loader procedure, grub shows it as preselected, the boot procedure in the end greets me mentioning this very kernel version, _but_ when I issue the command: uname -a in a command prompt, I am informed of using linux kernel version: 2.6.18.2-34-default #1 SMP PREEMPT
I am really quite puzzled, since I _cannot_ find any such vmlinuz file under /boot/ ! Could it be that my system properly runs with the expected kernel version, but uname mistakes it with a different one? Is there a way to determine the actual version of the linux kernel that my system currently runs with? If it's a problem with uname, have you got any suggestions that could potentially shed some light towards the origin/cause of the reported issue?
I have an cent os system,that i installed on my server. I have installed it with a graphical installation.(with graphic card) Now the system doesnt boot without a graphic card. I want use my server without a graphic card.
I upgraded form CentOS 5.2 to CentOS 5.3 and from VMware Server 2.0.0 to VMware Server 2.0.1 all work fine,but during boot when VMCI is loaded I've got the following message:kernel: vsock: no version for "VMCIDatagram_Send" found: kernel tainted.What does it mean? Have I to worry about it?
The first server I installed installed fine. The second server, installed with the same config, went to "kernel panic not syncing no init found try passing init= option in kernel" error. I tried reinstalling but it keeps going to that error after install reboot. The storage is ISCSI connected via Intel Server Adapter, which allows it to boot from ISCSI. Not sure if that's the cause for the problem, but the first server is connected to the same ISCSI and installed just fine.
Is there a way that I can make sure ISCSI module installs during installation? Although I think it is installed since it's able to copy the files and setup /dev/sda. I just wana make sure that it installs during setup.
The rest of the message is " located in /lib/modules/2.6.24-16-server/build". The version is Ubuntu server 8.04. Why can't it, and how can I help it along?
Sometimes a kernel image seems to have the same version as the backported kernel image, for example: linux-image-2.6.32-bpo.5-amd64 linux-image-2.6.32-5-amd64
Basicly just installed a fresh version of Cent OS 5.4 with apache httpd installed automaticly during the installation. The http daemon is running and when navigating to localhost i get the welcome cent os apache page thingy. The problem is when i put an index.html file in /var/http/www then try and navigation to localhost I get a 403 forbidden error.
