Linux file permissions problems

[sean04]

I'm having some difficulty running a program that is suppose to initialize my hardware. This driver was installed as root and when a user calls the initialize function from a user account, the program is able to run but, when this program calls the executable /sbin/insmod I get the following error:

insmod: "error inserting 'filename' " - Operation not permitted

But, when I run the same program as a root everything works fine.

What do I need to change to fix the problem?

[RobinVossen]

write down the current rights on /sbin/insmod
then give 777 rights to insmod

Chck out if it works now.

If so, Change rights to 620 (I hope I am right here).
If not, Change back to what you wrote down.

If the program works from root then the program has to be set to run as root. Make sure the owner of /sbin/insmod is root and then set permissions to 4755.

When you look at the file you should see:

# ls -l /sbin/insmod
-rwsr-xr-x 1 root root 7092 Mar 22 2007 /sbin/insmod
