depmod command in linux

[rahatekarabhijeet]

I am not able to run the depmod command because of /lib/modules/*/modules.dep is read only, due to failure of depmod command i am not able to run modprobe command. Because depmod creates the entry in modules.dep file, and which is used by modprobe command for it's execution.

On most systems, you will need to be root in order to run depmod, insmod, and modprobe.

i am executing those commands in root as a user.
i redirected the result in other location i ask for modprobe command to read from
that location by,
depmod -n module_name > file
modprobe -v < file
but this is also not working

It would help if you posted what error messages you are receiving when these commands fail to run.

Although you might be doing this, I just want to note that there is a difference between running AS root (switching using 'su -' or running a command via 'sudo'), and running IN the root directory ( / ).

Are you a member of the sudoers group, or did you switch to root using the 'su -' command before you tried?

Okay, time for you to explain a little more about your system.
What distro are you using?
Live CD or Local install?
What kernel version?
What Filesystem are you using?
What user are you executing the command as?

currently i am doing work on board support packages,
in which i am using squash fs in which dependancy file is read only with root
also,
that's why i am trying another way by which i can able to execute modprobe command,
so could it be possible to provide the things to modprobe command which it looks into depndency file by another way.
