General :: When Are Insmod And Mknod Not Enough?
Jan 19, 2010
I'm trying to install an open source driver BADDRV on Suse 11, x64 system.What I have done:installed kernel source. make. insmod ./BADDRV.ko.On Redhat 5, this just works and I can run the user program that calls open(/dev/BADDRV) and its ioctls.On Suse 11 there is no entry in /dev so I add mknod /dev/BADDRV c 0 0.The user open(/dev/BADDRV) fails with errno 6.(I also tried mknod /dev/BADDRV c 244 0, per suggestion of dmesg. No difference.)There is an rpm provided with the driver. Installing the rpm on Suse 11 works and then the user program works. The only problem with the rpm is that it requires kernel source to be installed, which I can't ask of my customer base.

I got "Invalid Module format" error while using insmod command. Later i understand that the file is compiled in previous version of Linux. But, currently i don't have the source files to recompile in new version of Linux. I have tried with -f option. Still, It is not working. Is there any other way to solve this problem.

I am using a windriver Linux. I have built the I2c-core, i2c-i801 and i2c-dev drivers and they are getting inserted while booting. After boot up, there are sysfs entries in /sys/class/i2c-dev/i2c-0 and /sys/bus/i2c/i2c-0. But there is no entry in /dev. In dmesg, it shows a line:
Quote:
i2c /dev entries driver. But it does not creates any entry in /dev.

I've a problem with character device mounting. I've a character device module code. Here is the code
Code: /* chardev.c: Creates a read-only char device that says how many times
* you've read from the dev file
*/
#if defined(CONFIG_MODVERSIONS) && ! defined(MODVERSIONS)

I am still new to porting wifi drivers. I am currently porting Ralink RT5370 driver, no problem with the compilation but when I execute insmod operation I got a lot of errors regarding RTMP. This is a part of the error I got:
rt5370sta: Unknown symbol rausb_buffer_free
rt5370sta: Unknown symbol RtmpOsFreeSpinLock
rt5370sta: Unknown symbol RtmpOsPktHeadBufExtend
rt5370sta: Unknown symbol RtmpOSTaskNotifyToExit
rt5370sta: Unknown symbol RtmpOsGetNetDevName
rt5370sta: Unknown symbol RtmpOsHtonl
rt5370sta: Unknown symbol RtmpOsAtomicInterlockedExchange
rt5370sta: Unknown symbol RtmpUtilInit
rt5370sta: Unknown symbol RtmpOSTaskInit
rt5370sta: Unknown symbol RtmpOsAtomicInit
insmod: can't insert '/home/rt5370sta.ko': unknown symbol in module or invalid parameter
Based on the some forum that I've read, adding the MODULE_LICENSE("GPL") is one of the solution. I did add it inside usb_main_dev.c and recompile but I still get the same errors.

i created a sample module and while trying to insert it i am getting the message "Killed". But when I did lsmod my module was listed out there and was 'Used by' 1. Maybe because it is in use I cannot do a rmmod on my module. How to overcome this, that is do a rmmod while it is still in use?

My team member want to use "mknod" command for build root file system of our project...
But, mknod is only excutable by "root".
I don't want to let them know the root password.
I think that "sudo" and "fakeroot" are the way to use mknod...
Except for those command, are there any way to use "mknode" ?
OR
Is there any solution for make "root file system ?"

I was trying to compile and insert a module. The module compiles fine and creates tool.ko file(am compiling it from Desktop). Next when I try to use "insmod tool.ko" , it gives em this error: insmod: error inserting 'tool.ko': -1 Operation not permitted.I tried to use modprobe instead , thinking it might install the dependencies(if any) by itself: "modprobe -v tool.ko" but it gives me this error
FATAL: Module tool.ko not found
I went over some linux forum posts and tried to resolve it but no use.I copied all the files from Desktop to the /lib/modules/2.6.34.7-0.7-Desktop/build folder and then ran the commands but still face the same problem. Used this "/sbin/depmod -a " thinking it might update the modeprob.conf file, but no use !

where the printk messages are stored when we call a insmod? I'm using Slackware, and I think my distro can store these messages on others place.

After a reboot, my PC just hang. It says "insmod : error inserting '/lib/raid456.ko : -1 File exists ..." then followed by a kernel panic. I have tried to boot using rescue mode but it couldn't find any Linux partition, thus no /mnt/sysimage was mounted. It left me at a shell and I'm stuck there.

I'm new to openSUSE and as a matter of fact, to linux too. I've got a Linksys WUSB600N wireless adapter which used to work fine with some live versions of linux that I was testing out before moving onto suse... Each time, upon booting using live CDs, I used to copy the driver I had downloaded from:
SpeedShare - Download rt2870-kernel-2.6.24-nemesis.tar.bz2
Then 'make' and get into the driver's os/linux directory to load the driver using 'insmod rt2870sta.ko' Now, upon doing a 'make' and 'make install', followed by the 'insmod rt2870sta.ko', I get the error saying:
insmod: error inserting 'rt2870sta.ko': -1 Invalid module format
I tried doing 'modprobe -rv rt2870sta' and didn't get any error messages. But while doing 'modprobe -v', this error shows up: insmod /lib/modules/2.6.27.7-9-default/kernel/drivers/net/wireless/rt2870sta.ko
FATAL: Error inserting rt2870sta (/lib/modules/2.6.27.7-9-default/kernel/drivers/net/wireless/rt2870sta.ko): Invalid module format

I am trying to install a third party driver and the provided makefile makes a call to insmod. Whenever I try to install this I run "su", so I am root and should have permissions. However, when I run "make install" I get the following output:
Code:
# make install
Unloading any instances of foo module
Loading new foo into running kernel
insmod: error inserting 'foo.ko': -1 Operation not permitted
make: *** [install] Error 1
Like I said before, I'm doing this as root, so I don't see how this is possible. Additionally, every time I try to do this it seems to cause a lot of damage to whatever kernel I'm currently booted in; USB and ethernet (and hence the Internet) stop working and I have to wipe the kernel and reinstall it.

My Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

PackageKit is a system designed to make installing and updating software on your computer easier. The primary design goal is to unify all the software graphical tools used in different distributions, and use some of the latest technology like PolicyKit to make the process suck less.

II'm a front-end web developer, I've always developed on Windows with technologies like XHTML, CSS, Javascript and Flash, I've dabbled with PHP and MySQL. I am well used to Windows workflows and tools, from Photoshop to Notepad++, Filezilla and WAMP server stacks to After Effects, and a swathe more - but always on Windows.I'm at a point where I think I need to start seriously developing on a Linux box, specifically at the moment to create web apps based on Node.js, but compiling tools and programs has become a task I'm more frequently required to do.
My question? I need to get my hands on a user-friendly install of Linux, but which one? I need common interface developer tools (lists welcome) to replace... well as many tools I have on Windows as possible.I need to be readily connected to the internet, I need OS updates to not destroy my workflow by crashing the OS, as I've seen Ubuntu do to various friends. I want efficiency, I need to be able to customise what I need to in order to perform development tasks.I guess this could be a long list, but - I don't have practical working knowledge of the Linux OS, nor how it "compares" to Windows (excuse my faux pas). I'm obviously willing to learn, but I'm far, far more keen to just... continue interface development, just on Linux instead of Windows.

He just want an account so he can use Squirrel Mail.

I have the impression that not that many people understand the scope and limitations of GNU General Public License. This is somehow my basic understanding of it. If I take a program covered under the GNU license, first of all I have the right to get the source code. Second, I can modify it at will. Third, I can redistribute it as will too but the new code will necessarily will have the same GNU license. This made me wonder how people actually can charge for software derived from Linux, for instance, Red Hat. Well, my impression is that they really make profit only out of services. In this thread [URL] I think I found a lot of confusion, even from a moderator (not intended to offend). Red Hat is based on Linux and it is necessarily covered under GNU. Somebody probably bought the program from RHE and can make it available at no cost.
Nevertheless, the moderator decided to warn the user. In this article [URL] it says the following:"Our training is not designed to promote vendor lock-in. Though these courses are based on Red Hat Enterprise Linux, the source code for [RHEL] is available to the community via the GPL [GNU General Public License]," said Red Hat spokewoman Leigh Day. This thread [URL] shows yet more confused people. Is there is a glitch in this type of license that prevents programs like RHEL to be redistributed for free? Why their license page doesn't mention GNU license? Or the problem is just that people get overwhelmed by this license and are afraid to be penalized and get paralyzed? By the way, RHEL is just the example. The key question is about the license!!

What is the general opinion of the Mandriva and Debian distros? Mainly asking what kind of user you consider the distro to be for (beginners, advanced, total newb, whatever), and whether you think they offer as much to an extremely experienced user as they would to a newb.Those are my two favorite distros, and I really like Mandriva a lot. I'm trying to pick one to stick with throughout, but I'm not really sure if Mandriva is too automated and Windows-user oriented like Ubuntu (I haven't really delved into the deeper aspects of Linux so I have zero experience in this area now). This might sound a little elitist but I don't want to be using Mandriva and just be automatically dismissed as a newb on first impression just because I'm using Mandriva (although admittedly I am a bit of a newb at the moment, I don't plan on staying one).
