General :: Compiled A Kernel With TUN/Bridge Support But Cannot Find /dev/net/tun?
Jan 20, 2011
I compiled my own kernel with tun/tap and bridge support. Both modules load fine at boot time (I could read that in the dmesg output). Now I want to use it, and the /dev/net/tun node is not there, so my application gives that error. I'm trying to bridge openvpn connections. Is it possible that udevd is not doing his work?
PS: I'm on a WD MyBook World Ed NAS device. It's ARM, so I cross compiled the kernel from my debian linux machine. I also installed debian on the NAS.)
I want to add Sandy bridge support to linux 2.6.32.20.I have linux kernel 2.6.32.20 ,and Sandy bridge changes were added from kernel 2.6.33.4.Please can anyone suggest how to backport the kernel support for Sandy bridge.
I have compiled and installed the mplayer tarball and I have disposed of both the tarball and its contents. There was the option to compile either for the physical console alone or for both this and the GUI. And I really don't remember which one I did choose.
About a month ago, I decided to go deeper in my Linux knowledge. I've been reading a lot and found out that Arch linux would be my learning distro. As I was installing Arch, it was a pain at first but I really learned a lot which I would never ever learn with Mint. Now I decided to take a step further is which "compiling your own kernel".
MY PROBLEM:
Everything was smooth in my Arch for a 2 weeks until I decided to compile my own kernel. I currently have a Nvidia GTX 460 1GB card.
BTW, the method I used to install nvidia with 2.6.37 was
Code: pacman -S nvidia nvidia-utils and that worked with all of the .37 kernels (-1 -2 -3 -4) which was download from kernel.org.
When I compiled the .38 (using the same .config of .37), it just boots up to the terminal (not loading gdm). However, I could still login by typing my username and password. So I've checked dmesg of both .37 and .38 and noticed that the Nvidia driver is not loaded in .38.
I tried reinstall it by running pacman and it doesn't do anything. It was thinking of uninstalling nvidia and nvidia-utils but there are so many dependencies conflicts (like screensaver, compiz, etc).
Since, I didn't want to mess up my .37 install, I just grabbed an old HDD and installed from scratch again. This time, I compiled the .38 kernel first (without gui) and then installed nvidia nvidia-utils. It was the same problem.
With this observation, I'm concluding that the nvidia and nvidia-utils from pacman is not compatible with .38.
I've read that I have to wait for nvidia to release a driver that will be compatible with the .38 kernel. Is that true? Does it mean I have to wait for nvidia/nvidia-utils to be updated from pacman? How would I know when it is updated?
I've also read about nouveau, but I guess that is not for me because it doesn't support 3D.
Is there a work around for me to use nvidia/nvidia-utils with .38?
Is nvidia and nvidia-utils proprietary drivers? What is the difference with these two and the one you download directly from nvidia?
First of all, I apologize for the bombardment of questions. As you can tell, I'm so clueless on how nvidia drivers work on linux in general (since it was spoon fed by mint) and I really would love to learn about this is a deeper level. Could someone please explain to me (LAYMANS terms) how nvidia works (and possibly a solution to my issue).
EDIT: Additional info - I have a netbook that also runs arch. It uses an Intel GMA integrated video chip which I used "xf86-video-intel" from pacman and I believe since it is open source, it works with .38 fine. So does that mean if you use an open source driver, it will work with all other kernels?
I read this on Patrick's twitter: Considering compiling future 32-bit x86 Slackware packages for i686 and finally leaving i486 and i586 support behind. Would the devs mind sharing why the change hasn't been made? I'm guessing there must be a lot of Slackware users with 15-20 year old computers that want to run the latest software.
I compiled my kernel, compiled scsi support into kernel, used the new kernel and initrd, the boot failed.Then ,i unzip my initrd, found that sd_mod.ko can't be insert, i added it manual, and reboot OK.so, why! in the kernel configure , the sd_mod.ko is set to <M> , but why it can't be found in initrd?
I just set up my Debian Squeeze (previously I was an Ubuntu/Kubuntu user) with KDE and Catalyst 10.8 to run my HD5070 graphics card. I've read alot on various forums of all the 5xxx users like me unable to properly setup the system and others who say thier video watching, wine game playing and composition are working fine. The problem is tearing while playing video or manipulating windows within the DE. I have read ALOT about this subject as it is obviously very important to me. I've read alot 60+ page threads on phoronics full of names like xv and libva and about using mplayer with gl so on and so forth. Problem is, I can't find a wiki to explain how they mesh together. My questions are:
1. Are certain libraries compiled with acceleration support? 2. If so, why are other libraries not compiled with acceleration support? 3. I get a feeling the libraries these guys are using are different ffmpeg and stuff that those in the repos. Are they? 4. If so, where do you get them?
In short, how does one get compositing and watch a movie tear free (the tearing occurs with or without compositing)? No amount of xorg.conf playing fixes it and the driver is properly installed with direct rendering.
I'm trying to find out when QME2572 (Qlogic) card became support by the kernel. We have a RHEL 5.1 system that is moving to new hardware, however the kernel at this release doesn't support the new hardware, due to the Qlogic card change. I tired the Redhat KB and Bugzilla. Is there a Kernel change list etc I can search. Never really played around with the kernel too much so I'm just after some pointers for looking up this information. Offically its not supported until Redhat 5.3, I'm trying trying to research kernel info so I can tell the customer they have to upgrade.
I have been trying to build linux from source code and run it from my machine (intel platform).
Here's what I did:
Code:
I am using Grub2. When I rebooted the new kernel was in the grub list all right. But booting from that kernel fails with no errors or warning. The screen just goes blank. The disk usage indicator LED also doesn't glow which I guess means that the kernel isn't being read from the disk. I rebooted using my older kernel and it booted properly. Then, when I listed my /boot directory, I noticed that there was no initrd.img for 2.6.39. kernel in there, which I think is the problem.
I am attempting to compile the linux-2.6.35.13 kernel from kernel.org to use with an installation of Fedora 14 (2.6.35.11-83.fc14.x86_64). I've done this before with different kernel versions for older versions of Fedora, but I've encountered a new problem this time. Whenever I get to the "make install" step, I get the following:Quote:
sh /home/user/testing/source/linux-2.6.35.13/arch/x86/boot/install.sh 2.6.35.13 arch/x86/boot/bzImage System.map "/boot"
After having patched the kernel with an ABI-patch I cannot find it in the grub2-Menu OS: Ubuntu 10.04 LTS in /boot I can see: the original and the new config-file
A while back I compiled a custom kernel, 2.6.35. I forgot to add UDF support when configuring and compiling. Will I need to re-compile the kernel to get UDF support or is there some other way I can add it?
I have a few ogg files that I want to put on my phone. My phone doesn't play oggs, so I need to convert. It's just an audiobook so I really don't care about quality. Oddly, nothing I try seems to be up to the task. Here's what I tried so far:
sox my.ogg my.mp3: "sox FAIL formats: can't open output file `x.mp3': SoX was compiled without MP3 encoding support" mencoder: wants video too?? Wha?? vlc (from GUI): "p, li { white-space: pre-wrapStreaming / Transcoding failed: It seems your FFMPEG (libavcodec) installation lacks the following encoder: MPEG Audio layer 1/2/3. If you don't know how to fix this, ask for support from your distribution.
This is not an error inside VLC media player. Do not contact the VideoLAN project about this issue." lame my.ogg my.mp3: "sorry, vorbis support in LAME is deprecated." audicity (via GUI): success..but I'm now going to have to somehow script it. This is very annoying. It makes me want to rip directly into mp3 from now on. Is there an easy way to convert an ogg file to an mp3 from the command-line?
The new 2.6.35.7 kernel fails to boot on my Lenovo laptop. I had previously compiled a 2.6.35 kernel with a couple of different .config files and never had it boot properly. The failure occurs very quickly and I am including the final screenshot in case that helps.
I have just started to work with BeagleBoard and built the Linux kernel (version 2.6.30.5) and download to the board and it start. I have also connected to the board over serial to Putty terminal.
Now I want to connect to the Beagle Board using USB instead of serial and I am looking for some info on how to do this.
My goal would be to connect to board over USB and then be able to: * Download my own binary files/programs from PC over USB to BeagleBoard * Communicate over USB instead of UART/Putty to get log and execute commands
Question: How do I build the Linux kernel with USB support, meaning what settings should be ticked in menuconfig? Or is it already included?
How do I enable USB OTG in menu config?
I assume I would need some driver on my PC with Windows XP to connect to my BeagleBoard over USB. Were can I find this USB driver?
I have installed VMware (VMware-Player-3.0.1-227600.x86_64.bundle) on my laptop. When I open Vmware from Applications/System Tools/VMware Player.I get a window that says: VMware Kernel Module Updater Before you can run VMware, several modules must be compiled and loaded into the running kernel.When I click on install and after putting in my passwd.a window comes up with a list:
But it just try the first one and show an error (window) that says.unable to build kernel module see log file /tmp/vmware-root/setup-9572.log for details.I cannot even go into the folder vmware-root because it says I do not have permissions even though am an administrator.
When using make menuconfig - under Device Drivers --> Character Devices --> there should be an option with the label "Enhanced Real Time Clock Support" (CONFIG_JS_RTC).
The problem is that this option seems to only show up while using the menu method when other options are either enabled or disabled and I've entirely forgotten what should be what. I swear fingered it out once.
This is on an older computer (P4) so HPET is no good.
You would think that disabling the HPET option would enable the RTC option but that does not appear to be the case.
I understand I can just add the option to the .config file and avoid this hassle but I'm very interested to know how to make this work.
To show my appreciation I will do something nice for you such as call you a nice name or tell you that you are pretty (or ugly if that's what you prefer).
I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.
I want to use GCC 4.1.2 on a SLES 11.0 x86_64 system. SLES 11 comes with GCC 4.3, so I compiled 4.1.2 and `make install`'d myself. When trying to use it, I get:
Code: # /usr/local/bin/gcc-4.1 hello.c /usr/bin/ld: cannot find -lgcc_s collect2: ld returned 1 exit status hello.c is simply:
[Code].....
basically, I took SLES' gcc-4.3 ./configure line and removed the prefix & path directives and changed the program suffix. Considering I don't know the use of half those options I'm trying again taking as many defaults as possible.
But I don't know what I am missing. How do I get it so that I don't have to use -L or -static to use my gcc-4.1?
