Hi,
I have a Linux redhat 9 machine and it is required from me to install some modules.

Before I start the installation, how can I make sure that a specific model (mod_ssl, tun, ...etc) are already loaded into the kernel??


Thanks in advance for your help

Cheers
Bassam

modprobe -c only shows the modprobe configuration - not whether a module has actually loaded.

lsmod is the one you want.

The easy way to load is using modprobe:

modprobe <module>

This will resolve module dependecies and load the modules you need.

Viewing all loaded modules is done by

lsmod


Hope this helps
