OpenSUSE Install :: Extract A Config From Running Kernel
Oct 17, 2010
I'm looking to extract a config from a working kernel..that much was pretty easy..all ya gotta do is "cp /proc/config.gz ." which will put it in whatever directory you're currently in and then do a "gzip -d config.gz" to get the config file.
Now...after that it gets a bit tricky..Linus says you should never compile a kernel in /usr/src/ because those header files in ../include should never change. He says you should extract a new kernel gz in your home directory and compile it there. I tend to agree (who am I to argue?). Anyway..whereever your sources are this is where you need to copy the config file...
Like this...my home dir is "/home/dart". So I would put the kernel sources there under "/home/dart/linux". I would cd to /home/dart/linux and do "cp /proc/config.gz ." then "gzip -d config.gz" which should leave you with a file called "config", then "mv config .config"
Now here's where I run into a problem..when I do "make xconfig" I get this...
Tried to install the qt3-devel packages from CD but guess what? I ran into cdrom errors which is what I was trying to fix in the first **** place...catch 22 eh?

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've read about some sort of tools that help with kernel configuration.Can anyone tell me anything about these?It seems that you use the tool(s) on a running system. You use the running system for a while. The tool(s) gathers data and leaves bread crumbs. The tool(s) then process the bread crumbs to create a candidate config file for a fresh kernel build. The goal is a kernel build that contains parts you actually use and omits parts you don't use or don't need -- all the while using arcane knowledge of dependencies among various kernel features to (hopefully) avoid building a still-born kernel.

I accidentally deleted my .config for my kernel configuration on Linux, and seem to remember there was a way to retrieve the kernel configuration via the proc filesystem somehow. Is this still possible, and if so how would I do it?

I have a config file called hosts.cfg.
It contains entries like this:
Quote:
There are many more of these entries in the file, over 500, all in this same format: each host has a "define host" followed by 18 directives contained in squiggly brackets.
If I want to know all the hosts that are in the hostgroup called SERVER_GRP, I suppose I would need to read every hostgroups line (8th directive in squiggly brackets) that contains SERVER_GRP and output the corresponding host_name line (1st directive in squiggly brackets) from that entry.

Firefox informed me that I should get the latest version. I naively listened to that voice, and was taken to a download screen. I downloaded it. I was hoping for a self-installer, because I'm used to windows. It opened in KPackageKit, or something named similar. I extracted it to my documents, because frankly, I have no idea where to extract it to. Anywhere's I've looked says that most software comes as a package, which you can search for and install in YaST. I searched for "firefox", and nothing new came up. how to extract things to the right place/install them correctly with YaST?

default in openSUSE 11.2 we have installed kernel-desktop. This kernel is optimized for the desktop.
What is the name of kernel optimized for server machine? In my case Firebird database + Apache + PHP?

I have a requirement where I want to extract the full name of the process running in my box. I tired various options of ps. The wide option gave me the full command but that contains command, the interpreter and also the arguments passed.
Code:
XX XX XX XX XX XX /usr/bin/sh /path/to/exe/myexe.sh arg1 arg2 arg3.
Is there any way from ps or any other command I can extract the full name of the command
Desired Output :
Code:
/path/to/exe/myexe.sh or myexe.sh

A few days ago yast did update my computer to a new kernel-desktop 2.6.31.12-0.1.1.
My mainboard is an ASUS P4P800-VM with Intel ICH5 chipset. This new kernel is not able, to poweroff my computer. Older kernels were able to poweroff the computer.
How can I roll back to the older kernel? Yast does only offer the recent kernel.
In /boot there are only files of the recent kernel.

Intel Pentium 4 HT, 3000 MHz, Frontside 800 MHz/Cache 1 MB
3 GB Ram
AGP nVidia 7600GS/512 MB, nVidia driver 190.53, installed from yast.

I have a Dell Inspiron 5160 with a volare xp5 video card (only recently supported under linux most linux distros and OpenBSD)Thus far I have done graphics install of KDE based on 11.2 and -- froze end of install and at at the logon / splash screen dueing the reboot could not get to a successful run level 3 text logon. (commandline was vga=x317, I think if n ot it was closeInstalled gnome using text install -- first boot (vga=normal - (default from install)) succeeded at configuring X and started gnome.
I really want KDE so I tried again Text install == hung near the end of the install after printers -- I assume trying to configure XRebooted no command line parameter at all ( no vga=) -- hung at login password screen (blank)Rebooted again with -- vga=normal 3 -- and got a text mode login prompt and successfully logged in -- now I can not find the page that talks about sax2 configuration from run mode 3. This video card needs to be set for VGA I think maybe vesa at 1024X768 16 colors (I succeeded at this under OpenBSD)I believe if necessary I can probably successfully edit the x config file but I would like to try the recommended approach first (as a non-root user as recommended) -- can anyone direct me to that page I cannot find again. It discussed 11.3 x config recovery with a section at the bottom for 11.2 and earlier

I just re-installed 11.3 KDE. I kept my old /home directory on a USB drive. Now I would like to replicate my panels. Where are the desktop config files kept?

Well, I decided enough of the "cute" OSs and installed OpenSuse 11.3 as my sole OS.
I have installed three times today. The install goes well, no issues there, however, after the install, I run Updates and once that's complete, I reboot and that is where the trouble starts.
The first 2 times, (I installed with Auto-magic Login enabled) all I could get was a black background and what the Mac community calls the "spinning wheel of death". Well since I automatically logged in I could not determine if it was a System issue or a Profile issue, hence the re-install.
I first thought it was a kernel update problem, but hey, the system boots, so that didn't seem logical.
I had on this install had it happen also, but I (thankfully) was able to graphically login as root and delete my /home/jj/.config and /home/jj/.gconf (going by previous experience with a similar issue on other OSs).
I notice that after the install and during the update that my Desktop Effects turned themselves off. I know this because Docky tells me so when I run it. Another issue is I run kmahjongg or kbounce (Wife's Games) and the TitleBar is missing so this forces me to (re)run metacity --replace to get WM handles back.
Everything is stable at the moment, but I hesitate to reboot the system.
I have logged out and back in with everything being retained.

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.

I have a system running openSUSE 11.2 with Desktop and XEN kernel, as well as Windows 7 (not by choice though...). I have noticed a strange time issue, with Windows 7 and the desktop kernel the time is correct (like for example now: 1:32 PM) but in the XEN kernel it is ahead several hours (6:32 PM). If it was an issue between openSUSE and windows then I would think that it is a problem with the system clock but I don't know what would cause a time issue between kernels like that.

differences between Kernel Default and Kernel Desktop? I've found some past threads like this link and this other link, and some other google info, which suggest the only difference would be the io scheduler. Also, I see the default grub choice is "Desktop" and not "Default", so I take this as a suggestion to prefer one over the other.
However, my broadcom 4312 wireless only works on the "default" and not on the "desktop" kernel, so I guess there must be other differences. I just want to evaluate which one is the less long-term risk option to go.

I have a question during a new kernel compilation (I made a backup of my .config) file) However I ran into issues during the make oldconfig process and unfortunately I issued a make clean followed by a mrproper which cleared my existing .config file.
Since I have a backup of my previous .config file is there of restoring without changing the permission rights to file?

No more than 15 hours after a breezy installation and setup I somehow managed to stop the desktop manager from displaying. Once you boot into Suse, the loading bar goes across, a white flash, then a blank screen forever. I figured it was KDM once I booted into x11safemode and tried to boot the desktop manager, it recreated the situation.
I've tried un-installing and installing KDM again, however it seems to reuse the same config file. I'm thinking about deleting the config file mentioned, but I'm not sure what will happen when I install the desktop manager, if there's any setting up to get it to work with my setup, or even if that will fix the situation.

I just upgraded an 11.1 install to 11.2. The upgraded system appears fully functional but I get many "all config files need .conf" warning messages during boot. See below. I also did a clean install on another system to compare and the clean install does not exhibit the same behavior so the warnings are evidently related to it being an upgrade. The system's working but I would like to understand why this is happening and clean it up. This system provides some key services to my networks and I have spent a lot of time getting this and the systems it interacts with "just right" under 11.1 and I am not particularly interested in starting over except as a last resort.

Things were running fine until GNOME misbehaved;
GNOME failed to load telling me:
Install error, Configuration defaults for GNOME power manager have not been installed correctly.
So I

None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? yes

I'm installing CentOS for the first time to run mythtv on (I previously used Fedora, but the new version cycle was too quick). As part of the instructions I'm using, I am told to run system-config-boot (to ensure that centosplus kernel is loaded on boot). The problem is, I cant find this option in my installation of CentOS. Another option I have is to manually edit the grub.conf file, but I'm not sure exactly how I should edit it.

I just done a brand new install of fed12 and did all the yum updates. Apache seems to start ok and I always liked the http config tool but it won't run on Fedora 12. I downloaded and installed system-config-httpd.noarch 5:1.4.6-1.fc12 and it all went fine but when I try to start it I get the usual box asking for my root password, I type it in and press enter, the box disappears and then....nothing. If I run system-config-httpd in a terminal I get the same box asking for root passowrd but when I enter it I get a long scroll of text which ends with:
line 4: 2137 Aborted (core dumped) /usr/bin/python /usr/share/system-config-httpd/ApacheConf.py
I don't know what causes this. Is there any way to get the http config tool working?

I'm experimenting with 2.6.33-ck1 mainly because I want to try the BFS. I successfully configured and installed the patched kernel, but I'm experiencing various problems on the desktop. The biggest is Chromium not working at all, but there are several others, including graphical glitches in firefox. I'm sure I left some important module off or made a mistake for some settings My question is that is there a 2.6.33-fc12 kernel yet, and does it have a .config available? I'd like to load those settings in menuconfig and use them as a starting point to properly configure and complie a -ck patched kernel.
