What Programs Are Needed Under Redhat ?
 

What programs are needed under Redahat 9.0 in order to do Modprobe, lsmod, insmod ?

it should be able to do those out-of-the-box, as long as you are root...

This is what I get

[root@localhost dad]# modprobe
bash: modprobe: command not found

They're located in /sbin and its not in the path when you 'su', by default in redhat.
Therefore either use 'su -' or invoke the command with the path, ie '/sbin/modprobe'

to check what's in your path do a:

echo $PATH

to add "/sbin" if it's missing from that output just edit "/root/.bashrc"...

(i think it's .bashrc on redhat, i know it is on mandrake which is based on redhat...)

when u su
do 'su -'
