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?
View 1 RepliesI'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.
View 6 Replies View RelatedI'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?
Can I use the config for my current kernel (the jessie 3.16 one), and use it to build a more recent kernel (3.18)? Do I just copy across the config and try and build with it, or is there some tool that will bring across the existing config but also set up reasonable defaults for any new options in the newer kernel, and any other migrations that might need to be applied?
View 4 Replies View RelatedI'm recompiling my kernel on a dell latitude c600 running lenny as I type, and it's taking forever, so far upward of 4 hours.I think I'm getting drivers for ever piece of computing hardware since the univac So I googled "a kernel conf creator" and got [URL]... Its a nice, clean method for finding what hardware your using... you just run lspci cpuinfo make xconfig and put in all the info yourself. So I was thinking: this is exactly the kind of dull, repetitive behavior that computers were made for. Is there a program that can find my hardware info, and make the.config itself, with very little user input?Or should I reinstall debian on another partition and steal the .config from it? Or should I man it up and do it myself?
View 14 Replies View RelatedI'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.
View 2 Replies View RelatedI'm trying to set up my Intel Wireless 3945ABG (which is supported in the kernel) and I don't understand where to start if I want to use systemd to do this.
I've installed my Debian (Stretch Alpha4) base system using the wireless to download the necessary components but when I boot into the system I need to set up the wireless card separately.
I would prefer to be able to install wireless without the requirement of connecting via ethernet so no package installs other than what is downloaded by the installer.
I can't even find documentation on this specific issue because everyone seems to reference /etc/network/interfaces which AFAIK is not supported in systemd. How do I configure a wireless card using only systemd?

View 2 Replies View RelatedI'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:

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 run a network with about twenty Debian systems, currently running Etch. I maintain a central passwd and group file, which is regularly copied to each system. This works fairly well, but I have some problems with the system account UIDs and GIDs.
I find different systems often pick different UID and GID values for system accounts like bind, ntp, sshd etc. I think the values chosen at install come from the system UID and GID ranges, and are allocated sequentially, so the values on a system depend on which packages were installed, and the order they were installed in.
Is there any way to specify the UID and GIDs for system accounts at installation time? Are there any other thoughts on how to implement shared passwd and group files (apart from NIS, which I don't want to use)?
This may fall under the "ain't broke don't fix it" category but it's driving me nuts. I've got the Broadcom 4322 wireless adapter in my laptop and it works fine with broadcom-wl driver and kmod. However there is no ifcfg-eth1 file and the card does not show up in system-config-network.

I have also opened a terminal and run it from the command line (/usr/bin/system-network-config) and I get the same "Unknown error" pop-up. I was not the one who originally configured this server, so I am not sure of the history or how it might have been broken. I can't seem to find any debugging information or even any command line parameters that might give me a clue what the complaint is. There is no error number or any other helpful hint as to the cause of the problem.
I have been manually editing the config files so the server is up and running but it is tedious to manage the server without the GUI.Has anyone seen this before?

They have broken something in their download site and it is no longer possible to get the latest flash player in a .deb package by direct download. The FTP site is years out of date. And there is no way to get through the "help' system to contact the people running the web site.
