how to prevent a module to load ?
I mean I dont want the "fealnx" module loaded automatically, at system startup

# lsmod |grep fealnx
fealnx 38664 0
mii 22400 1 fealnx

# grep fealnx /etc/modprobe.d/blacklist
blacklist fealnx

# modinfo fealnx

# rmmod fealnx

then reboot the system, but module "fealnx" is loaded... why ?
I have restricted the "usb disks" via the "blacklist" method successfully, but the blacklist method(/etc/modprobe.d/blacklist) is not working for this module(fealnx)

Well, someone more knowledgeable might tell me this is an inelegant solution, but you can try adding the line

install fealnx /bin/true

to /etc/modprobe.conf.

thanks reed9 .. yes your solution works

but why its not working the way I was doing, i.e in
/etc/modprobe.d/blacklist
blacklist fealnx
?

thanks once again for help

My guess is, somewhere some system service needs the module, and that overrides the blacklisting. The install /bin/true line means, whenever the system attempts to load the module, it's forced to execute the command 'true', which does, well, nothing, and returns success. So the module never loads.

Hmm nice explanation, but I think in my case that should not be the reason, because this module(fealnx) is for the NIC (Myson 100/10M Ethernet PCI Adapter), and I have set this nic to

BOOTPROTO='none
STARTMODE='disable''

so I think that "any system service should not need this module".

well I am not arguing with you, I am just sharing the thoughts of a dumb(i.e me)

once again thanks for nice explanation
