Can anybody tell me how modprobe knows where my module is located?
How can we change that path?
Thanks in advance.
bye,
Eshwar

just type in a console "man modprobe" it tells you what you need to know. the config file is /etc/modprobe.conf incase you need that too. it looks under /lib/modules/2.X.X/kernel for the main modules

modprobe is a program that can be deleted if ya want to (i did), its just a symlink to insmod (with some tag i think), but for simplest module loading just type
insmod (modname)
like:
insmod unix (for unix domain sockets)
insmod isofs (cdrom files system suport)

I know that friend i am asking about modprobe probing Path.
its ok i have found it. But i dont know how to change it.
if you know please let me know.

can you tell me how this "modprobe" fetch the module path?

The path "/lib/modules" is hardcoded into modprobe.

The complete module path includes the kernel version number like what the command 'uname -r' returns

The path to modprobe itself is configurable directly in the kernel:
'cat /proc/sys/kernel/modprobe' will tell you the current value. You can do:
'echo /path/to/my/mdoprobe > /proc/sys/kernel/modprobe'
to change that value.

modprobe is not the same as insmod -even if modprobe is a symlink to insmod. if the program is called as modprobe, then it does module resolution, first installing any modules needed by the one you are trying to load.

This is a really, really old thread you revived...

yes...its old thread...i am newbie...so i want to know from which path the kernel will load all the modules while booting..?

/lib/modules/current-kernel
That is, modutils is aware of the version of the running kernel and uses whichever path matches that. The last part of that path would always be what matches the output from the command 'uname -r'.

The content of /lib/modules/2.6.26 is

sharief@sharief-desktop:~$ cd /lib/modules/
sharief@sharief-desktop:/lib/modules$ ls
2.6.26
sharief@sharief-desktop:/lib/modules$ cd 2.6.26/
sharief@sharief-desktop:/lib/modules/2.6.26$ ls
build modules.dep modules.ofmap modules.symbols
kernel modules.ieee1394map modules.order modules.usbmap
modules.alias modules.inputmap modules.pcimap source
modules.ccwmap modules.isapnpmap modules.seriomap
sharief@sharief-desktop:/lib/modules/2.6.26$

in this which will the correct file used to load the modules when kernel boots?

Those mapfiles are used to alias the location of the modules. They are not the mdoules themselves. modprobe uses configuration files under /etc when they are present /etc/modules.conf or under /etc/modules.d
What is it exactly that you want to know or change?

i didnt have any file called /etc/modules.conf or module.d...

i have only this files under /etc:
modprobe.d
modules
modutils
in this which file you are telling?

It can be anyone of those. modprobe can use several different ways to find out how to load modules and the names of the files and location have change some over the years. You still don't say what you are trying to do. I can't really help you if I don't know what you want. Do you need to force loading of certain modules, or pass parameters to modprobe for certain modules?
If your system uses hotplug or udev, then those systems are responsable for loading most modules, so it gets even more complicated. What was your question again?

Actually my question is from which path the kernel loads the "modules" when kernel boots?its from which path..you told that "/lib/modules/uname -r"...under that directory there is lots of files...i want specific file under that directory....and how it loads..thats my question....

The o/p of /etc/modules is:

sharief@sharief-desktop:~$ cd /etc
sharief@sharief-desktop:/etc$ cat modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

fuse
lp
sharief@sharief-desktop:/etc$

The o/p of /etc/modutils/ is

sharief@sharief-desktop:/etc$ cd modutils/
sharief@sharief-desktop:/etc/modutils$ ls
bluez nvidia-kernel-nkc
sharief@sharief-desktop:/etc/modutils$

The o/p of /etc/modprobe.d/ is

sharief@sharief-desktop:/etc$ cd modprobe.d/
sharief@sharief-desktop:/etc/modprobe.d$ ls
aliases blacklist-framebuffer bluez lrm-video
alsa-base blacklist-modem fuse nvidia-kernel-nkc
arch blacklist-oss ipw3945 options
arch-aliases blacklist-scanner isapnp thinkpad_acpi.modprobe
blacklist blacklist-watchdog libpisock9 toshiba_acpi.modprobe
sharief@sharief-desktop:/etc/modprobe.d$

which is correct one in the above file and directories...i am not sure..Thats why..Thanks
