Fedora Servers :: BUG: Unable To Handle Kernel Paging Request At [xxxx]?

Nov 10, 2009

[Note: I'm typing this entire thing out. It probably isn't 100% verbatim. And I am using an older version of the kernel because 2.6.30.9.96 was not behaving either.]

Code:

CentOS 5 :: Unable To Handle Kernel Paging Request?

Apr 8, 2009

I am trying to install CentOS 5.3 on a computer where I successfully installed Windows XP.

Booting from the DVD I got the following error:

OpenSUSE Install :: Unable To Handle Kernel Paging Request At Ffffc90010b8000?

Aug 3, 2010

I've been trying to install Opensuse 11.3 from the Kde live cd, but the installation hangs when I'm almost done. Right at the beginning the installation is interrupted right with text that among other things says:

Bug: unable to handle kernel paging request at ffffc90010b8000. After a while though, the installation picks up and continues by itself. I'm then able to complete the necessary steps and I reboot the system so that it can complete the installation.

After reboot there is a new text message that says that the bios does not support EEC memory or something to that effect and then continues with the installation. When it has completed 82% of the autoconfiguration the installation just stops and stays that way.

I've had no problem installing previous releases, from 10.2 up to 11.2, on the same machine.

I've checked md5 sum and also checked the media before proceeding with the installation.

Upon reboot after the first installation step, I also tried the failsafe mode but got the same result.

On the January 31st Oops, I just rebooted. On the March 14th Oops, I reformatted the two swap partitions as follows: mkswap -c /dev/sda2; mkswap -c /dev/sdb2 On this last Oops, I turned off the swap for 24-hours, then decided to turn it on again after doing the above mkswap again. During the previous uptime, I had dumpcap packet capture running, but this last reboot, I'm not going to run it.

Fedora Servers :: FC10 Kernel Panic - Stale NFS File Handle

Mar 20, 2009

A FC10 server hung and had to be power-cycled. I suspect it hung because of an nfs mount timeout.

Now it does not boot. The error is libc.so.6 not found. Kernel panic. Attempting to kill init.

Booting under rescue:

ls: cannot access libc-2.8.so: Stale NFS file handle

Is there a way to reboot to a clean state? There must be some NFS cache file.

I also tried to cp rescueCD:/lib64/libc-2.8.so to the old lib64 dir, but get the same "Stale NFS file handle" message.

Fedora Hardware :: NVidia FX5200 Only Works With An Old Kernel Xxxx.i586?

Feb 1, 2010

I was helping my cousin move to the GNU Linux world and I was faced with the following problem: He has a MSI nVidia GeForce FX5200 PCIe (128MB vRam) Graphics card. I followed a couple of instructions here in getting that card to work, but the drivers that I was able to load up to his 23 bit system refused to load after system boot up (white flashing letters would come up, X server refusing to load). I was only able to load the system with full 3D hardware accelerated support when I loaded the old xxxxx.i586 based kernel from the GRUB list, while the current kernel that was being used was xxxx.i686 based one.

Currently there was two kernels in the list, so I manually edited the GRUB file to change the boot identifier number from 1 (xxxx.i686) to 0 (xxxx.i586) so every time that the computer would be powered on, it would load that kernel up automatically without having to reselect it manually each time.

Yesterday, my cousin picked up his computer, he was fine and happy with his fedora core (version 11, because Version 12 had major problems with this graphics card, its on the "test" list still, and the developers of fedora, or the developers of that other 3rd party software source seems to be in the middle of testing it for FC12 compatibility)

He told me today that after he ran the "updates" for fedora and installed them, when he rebooted the system, he would see that same while characters in the top left section of the screen flashing and it would get stuck there, he told me that he was able to solve the problem by rebooting and selecting the xxxxxx.i586 kernel from the list. He also told me that he saw three kernels from the list.

For what I see here, this driver will only load with the i586 based kernel, and I also am seeing that each time that he updates his system he may have to go thru this again. My question is this: Will fedora 11 change his default kernel each time that he runs Fedora Updates? If so, what can I do to prevent that change from occurring.

Also, is there a limit on the kernels that appears on the GRUB list, if each updates brings a new kernel entry on the GRUB list, will the list get very large one day? or will Fedora remove one or more kernels, in other words, what is the maximum number of Kernels Fedora keeps on the GRUB list? and will there be a point that Fedora updates will delete that working i586 kernel leaving him with a non booting system? Or will that nvidia driver "magically" start working with some future update after the developers fix/improves what ever is keeping that nVidia driver from loading with the latest updates?

Ubuntu Servers :: Handle Splitting Services Up Between Two Servers?

May 29, 2010

I got my hands on a couple old servers. An HP tc2021 and a Proliant ML110. Sure they're ancient, but I thought they would make a couple of great Ubuntu Servers for a new "start up" business I'm trying out. Now I've got to decide the best scenario to distribute the load between the two servers. I'm going to make an internal domain and will probably be running the following: Kerberos, Samba, Apache, Postfix, mysql, bind, dhcp, SVN, GCC, and Nagios. So in summary, I'll have the following roles; domain controller, web server, file server, and network monitoring services. how they would handle splitting these services up between two servers?

Fedora Installation :: Xen-kernel - Unable To Boot In Normal Kernel

I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.

Ubuntu Servers :: Unable To Select Server Kernel With Preseed?

Jan 6, 2010

I'm currently trying to use preseed to build an ubuntu server box over the network. I'm using the netboot.tar.gz from the karmic main mirror. By default it installs the standard kernel (linux-2.6.31-16-generic), and I want to use the server kernel (the metapackage linux-server which should install linux-image-2.6.31-16-server). I'm using a minimal build:

d-i base-installer/kernel/override-image string linux-server

Ubuntu Servers :: How Many Connections Can XAMPP Handle

Jul 23, 2010

i would like to know how many connections per sec/min/hour, xampp can handle. I'm going to run SMF forum on my box, because i'm not ready yet with real server solution. System stats are: G31M-S2C; 2x2GB Kingston@920Mhz; E5200@3500Mhz; 500GB@7200 Seagate, all powered by Lucid x64. In a time i will migrate to a quad, mobo with raid support, etc. but at that point i'm want to know how much connections can xampp handle. Because of the forum nature, i think of auto deleting topics witn no new replys in 5 days for saving place (there will be minimum 1 and maybe max 5 photos per thread, maximum size 2Mb for each).

Ubuntu Servers :: Handle Webroot Permissions When Uploading?

Jul 29, 2011

I have been plagued by this for some time. How many times do you need to run chown -R user:www-data or similar to your webroot directory.I have been searching via Google and this forum. I have yet to find a definite answer to handle uploading and creating new files usable by apache2.Scenarios can vary. Some folks put there webroot inside a /home directory. Some users leave the default location as /var/www.I have a two part question.. Why do I often read "Apache runs as user=www-data, therefore files need to be readable by such (www-data)", but the default install in Ubuntu includes an index.html with the following?

Code:
ls -l /var/www

Debian Configuration :: Network - Access Servers Request Failed

Feb 1, 2010

I recently installed two PC with debian lenny (kernel 2.6.26). One is called serveur-debian1 and the second one serveur-debian2. I have installed gnome,samba, mysql5, apache2, php5, and Virtualbox,bridge-tools on them. On serveur-debian2, i installed an other virtual debian lenny with apache2,mysql5,php5,nagios and centreon on it to view my network. I remember having installed a soft to access nntp on serveur-debian2 in order to test nagios.

Since a few days, i have problem to access to my servers. rom my windows 7 client, i try to ping serveur-debian1. Response is OK but not for all resquets Always from the same computer, i try to ping serveur-debian2. Response is OK but not for all again.

When i launch a ping on serveur-debian1 and serveur debian2 at the same time i have:

ping 1 to 10: serveur-debian1: response OK
serveur-debian2: no response
ping 11to 14: serveur-debian1: no response
serveur-debian2: response OK
ping 15 to 25: serveur-debian1: respone OK
serveur-debian2: @ip serveur-debian1 network unreachable (there's no error, it shows me the ip of serveur-debian1)

If i switch on the debian virtual server on the serveur-debian2, and i ping it at the same time, the response is OK for all resquests. The problem is very strange. I can't have a correct connection and when i launch a request from a software which access the mysql server, the requests failed ...

Ubuntu Servers :: Controlling Files Listed By Directory Request

May 5, 2011

I use Apache 2.0.55 (Ubuntu) as a document server for a business association. When the document files expire, I change the permissions so that only the owner can open them but I like to leave them on the server so that they are all in one place.

Here is my trouble--when visitors come to the site and get the directory listing, all the document files show up, whether the visitor can access them or not.

Is there some way to configure the server to not show the inaccessible files?

I guess a few technical details might help. During their useful lives, the files permissions are set to 644. Once they expire, I change them to 600. After the change, the files are still visible. Setting them to 000 doesn't help either.

It might be of note, but directories behave differently than files. If I set a directory to 600, it disappears from the listing.

Ubuntu Servers :: Trigger A Shell Script Upon DHCP Request?

I have decided that I am OK with only one being able to have an Open NAT at a time, but I want to change the firewall rules according to which Xbox 360 turned on first. This way I can move between level in my house and play online without having to modify rules manually.
