Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Ok, I'm a relative Linux noob. I've managed to successfully download, make, make install, and cp the daily tarball for the rt2570 drivers (rt2570-cvs-2006031713) into rt2570.ko just fine. All of this was done as su (root privileges).
Then I get to insmod (still su, mind you), and I get back:
bash: insmod: command not found
I checked, and kernel-devel is installed. I'm running FC4 with kernel 2.6.15-1.1833-FC4 in i686 mode.
I did a man insmod, and I got the man page to come up for it, but no insmod itself. I'm guessing there's a package I'm missing, but I'm not sure what it is. I ran yum upgrade successfully just a couple of hours ago. Any help would be appreciated.
Thanks-- going into /sbin and running insmod and depmod as ./insmod & ./depmod -a worked.
Now the next question is how do I change the root's path so that next time it'll work without having to go into /sbin?
If you use 'su -' (note the dash) as the guy above said, then it also switches all the users environment variables so roots PATH also gets used, unlike 'su' which uses the current environment variables. This means /sbin will be included because it's in root's path.
Thanks. I understand it now. I looked back at the HOWTO for the rt2570 driver, and I missed the "- root" after the "su", thinking that just using "su" was enough. Thanks for the info-- I understand the use of "su" much better now.
