So I'm sort of new to this, and I just experimented updating my Web server and Database server (containing no important data as of yet) to a new kernel version - Ubuntu 12.04.x x64 vmlinuz-3.8.0-38-generic. The install went very smooth, and nothing bad (seemed) to happen. While trying to install UFW for security purposes ... I needed to check if a module was running for them to work ... so I decided to type the command "lsmod" to see what modules were running. My Database server and my Web server have completely different modules running, but nothing was affecting either from hosting my sites. So I guess my main question(s) are, what modules are important and which ones should be running on start-up for security/stability (or does it matter?)? Also, is there a way to load all modules in /lib/modules/VERSION? And if so, would there be any benefits in doing so? And my last question, how come my Web server and Database server have different modules loaded (see blow)? (The Web server was originally installed with Ubuntu 12.04 x64 + Ghost 0.4.2 ... and the Database server just has Ubuntu 12.04 x64). My Web server is working just fine with only "floppy" running, but I'll need to enable a few more to make UFW work. On the other-hand, are all the modules currently loaded in my Database server necessary? (see below) ---------------------------------------------------- I'm just going to give a sample of what modules my Web server and Database server are currently running below to see if it helps answer any of my questions above: DB-SERVER = kvm_intel, kvm, vmwgfx, ppdev, ttm, microcodde, drm, psmouse, serio_raw, i2c_piix4, parport_pc, mac_hid, lp, parport, floppy WEBSERVER = floppy
