What is the name of kernel optimized for server machine? In my case Firebird database + Apache + PHP?
I am using eclipse, and whenever a pop-up appears (like auto complete, error detail, suggested fix - usually triggered by mouse-over) over the text field, the caret no longer types. I imagine the text field lost focus when the pop up appears but never got it back.
I can re-enable typing by either alt-tab, or switch workspace then back. But it is REALLY annoying since I need to do this every 30 seconds. The same problem happens to terminal, tex editor, and many other text fields.
I am using an ACER Aspire ONE (N270 atom, 2GB, Intel GMA945). I noticed after upgrading to 2.6.32 kernel but now I have checked with older kernels, they all have the same problem.
How to check kernel type before install whether it is 32 bit or 64 bit in Redhat Linux.

When my computer boots, it tries to mount it as EXT3 then EXT2, fails both types and then tries EXT4. Here are the messages.
Code:
EXT3-fs (sda2): error: couldn't mount because of unsupported optional features (240)
EXT2-fs (sda2): error: couldn't mount because of unsupported optional features (240)
EXT4-fs (sda2): mounted filesystem with ordered data mode
So, eventually / is mounted correctly, but I think this is slowing down my boot time. Does anyone know how to fix this.
after updating kernel and installing nvidia drivers, the startup splash(I dont know the proper word) has changed into bar type. How can it be corrected .

previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive
I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.

sh: gnuplot: not found
Just to double check my work, I ran the following code:
y=[1 2 3];
plot(y);
I am copying the file form one directory to another directory using shellscript.
Here i want to get the Mimetype/Content-type of the file.

I recently installed debian squeeze 32bit on a second partition of my amd athlon 64 X2 dual core machine.Currently it is using linux-image-2.6.32-trunk-686 kernel.But linux-image-2.6.32-trunk-amd64 is available.on the repository.Is it a 64bit kernel or 32bit kernel optimized for amd64 architecture?

I am an experienced Linux admin and have been using SuSE for many years. My development machine has had every version of SuSE since '02 and although it is a little old, is in good working order. (AMD
2400, 2 gig RAM, 160 Gig IDE disks - SuSE on disk 2) (OpenSuSE 11.1 with the latest kernel works perfectly. This install is on a spare HDD prior to doing a full install on my usual HDD.)
When I try to install SuSE 11.2 from DVD, the load kernel operation hangs at 97% (using both normal and safe kernel), however, I can install from live CD without any problem. I have tried the same DVD on a few "older" machines and had the same problem. I initially thought it was the actual DVD but re-burning has the same problem. I have also tried another DVD writer - same problem.

Code:
I would have thought that removing a given kernel package would trigger the removal of the older kernel headers. Can someone confirm that is, or is not, the behavior? I ask this because it seemed to me that the older kernel header packages were indeed removed when I removed some older kernel packages.
For example, the linux kernels I have installed are:
Code:
Also, the linux-headers packages I have installed are:
Code:
So, when I get around to removing the linux-image-2.6.25-2-amd64 package like this:
Code:
I would expect apt-get to automatically also remove linux-headers-2.6.25-2-amd64 and linux-headers-2.6.25-2-common. Is that what will happen, or do I need to explicitly state all three packages on the apt-get remove command?
The 486 kernel works just fine, and while I have only 1GB of RAM at the moment I hope to have 2GB someday and would like to take advantage of the dual core CPU, so I would like to configure grub to run the 686 kernel by default. For whatever reason, it runs the 486 right now and the 686 fails in a major way: there is no network connectivity at all. It could be plugged into my cable modem router and it shows no wired connections. The fact that one works and the other doesn't puzzles me since I haven't touched either since the install and a few rounds of upgrades.
I should mention I'm newbie but getting better; I managed to install debian on this x60, yet while preserving the factory install rescue & recovery partition and preserving the factory install MBR so that ibm-specific hardware functions (thinkvantage button, etc.) still work. This required me to use dd to copy the first 512 bytes of my debian partition to a file in the windows partition, etc., and modifying the windows bootloader. (I wish I had learned dd long ago--it rocks). I did this because if I ever resell the X60, the fact is most people use MS Windows and having that partition adds a perception of value to some potential buyers; not to mention I paid $ for it (I was young & stupid) so why should I delete it. I also backed up the recovery partition on another drive using dd over NFS in case the hd ever heads south.
Anyway, I've never been comfy with messing with the kernel. I did once recompile a module for ALSA because it had a bug in it for an old Yamaha integrated sound card on an old PIII and the newer version worked [alsa fails on this x60 too but I think I found a post on here that has a solution I will try later]. But I'm clueless as to networking modules, not to mention the correct module is installed already from Intel for this chipset. So what is there to do?
Here's a clue: the ifconfig output is radically different from the 686 and 486 kernels. Looks like hardware is not being detected since eth0 fails to show:
I would show the diff output below if it weren't so long--and not allowed--upon 2 text files, the first holding the output of modprobe -l under the 486 kernel and the second under the 686 kernel.
I'm attempting to install the driver for my atheros AR8131 PCI-E Gigabit Ethernet adapter (in my Lenovo laptop) on my newly installed RHEL5 system (it's not currently being recognized).
I tried using: 'make install' but hit an error "Makefile:61: *** Linux kernel source not found."
After this, I tried: 'sudo yum install kernel-devel kernel-headers'
To rectify this, but hit this error "No package kernel-devel available" (and the same for the headers). What should I do?
I am using DEBIAN 6.0 and I wannna update my kernel from 2.6.32 to 2.6.38. Every time, I do it but after the installation & rebooting into the new kernel it gives me error "UNABLE TO BOOT INTO THE KERNEL".

I'm trying to run extract-ikconfig because I've mistakenly deleted an old kernel config that I'd like to recover. However, when running the script from the latest (2.6.32.5) tree I run into this error:
Quote:
ERROR: Unable to extract kernel configuration information.
This kernel image may not have the config info.
Coincidentally, this happens with all of my kernel images. Is it a fixable problem? I should really set CONFIG_IKCONFIG_PROC next time..
I have recompiled a few kernels, but all on 32bit systems so not sure if that has anything to do with it.
Running Arch Linux 64bit, most recent version.
Kernel Output:
Code:
My first thoughts was that it might be my grub bootloader configuration, so had a big play around with that but it didn't fix it. Also made sure support was built for filesystems. However almost all that Fstab mounts are ext3 anyway, and certainly the root and /boot are. Now thinking it may be a memory error so will run a check when I shutdown.
Dell laptop booting from a USB stick with a CentOS 5.5 minimum installation.

1. Does minimum installation not drop on a kernel or initrd with ext3 support? I can't imagine that's true, but have to ask.
2. The USB stick is single partition ext3. Maybe there is some limitation specifically related to USB stick booting that requires boot to be FAT16 or FAT32? Except the CentOS 5.5 installer refuses to let me install on either FAT.
3. How can I do the equivalent of lsmod on a linux installation that will not boot? i.e. I have CentOS x86_64 running in VirtualBox, I can plug the USB stick in there, so how do I get information on the USB stick's kernel and initrd if I can't boot from it?
4. Is it possible to rebuild the i386 based initrd on this USB stick, when the computer is not booted from that stick, with a system that's x86_64 based?
System Info:
Dell Latitude i686 Laptop which has run CentOS 5.5 and Fedora 12,13,14 in the past, and boots from Fedora 14 Live CD transferred to a USB stick. So I know USB booting is possible on this machine, and this stick.
The process of creating the stick:
CentOS 5.5 i386 on a USB stick. Old Dell i686 laptop which has previously run CentOS 5.5 installed from DVD, and has successfully booted from this same USB stick holding transferred Fedora 12,13,14 Live CDs. CentOS 5.5 was installed onto the USB drive directly by the CentOS 5.5 DVD installer (running virtualized in VirtualBox 4.02 on Mac OS X 10.6.5.). No errors or complaints during installation.
For whatever reason, the installer did not do some things correctly. First Grub wasn't working correctly, I got that sorted out and have the Grub+CentOS splash screen, it finds vmlinuz and the initrd, and then I get a kernel panic.
Ext3 was built into the kernel and that's why I'm getting this message. I do not know how the installer would have dropped a kernel or initrd during instalation that that don't contain such a basic thing that obviously comes in linux kernel 2.6.18-89 EL.
I write the network driver. Transmission of packets in user space I do through netlink socket`s. In user space there is a handling of packets and their transmission on other device (however, it isn't important).
Problem in that any time, packets through the driver in system, and is reverse, are transferred normally. But then there comes the moment when the kernel crash. If to look in syslog it seems to me that comes deadlock. Also I think that it is related with netlink socket`s.
I can't find the information on that anywhere how correctly to use netlink socket`s in kernel space. Can at you will any a reason into the account of synchronization of sockets and the driver in kernel space?
I can give the driver code if it is necessary.
