How to PERMANENTLY Remove a KLM?

RWild · 07-28-2003, 06:48 PM

Somehow I got a Cyclades multi-port serial module installed. It is a major interference in trying to log on but I cannot get rid of the damned thing. I have tried /sbin/moprobe -r cyclades and /sbin/rmmod -r cyclades. Both temporarily remove it from memory but on reboot, it's back.

I have some small cron files but crontab tells me that there are no cron files for any user on the system.

How do I find the Cyclades module and how do I get rid of it PERMANENTLY for all users?

Do you have it in your /etc/modules.conf?

No - nothing there about the Cyclades module.

The next thing I would do is to grep my rc directories for the string 'cyclades' to see if it is being modprobed at all. To be safe, I would grep /etc itself recursively, redirect output to a file and check every occurance.

Code:

#!/bin/bash

# fts - full text search

if [ $# -lt 1 ]; then
    echo "fts - Full Text Search"
    echo "Usage: $(basename $0) <searchText>"
    exit 1
fi

for  i in $(find . -type f -print); do
    if [ -r $i ]; then
        grep -Hi -e "$1" $i;
    fi
done

exit 0

A bare-bones script like the one I use may be used to do the text-search regular files starting from the current directory. A word of warning: the script assumes non-space-delimited filenames, does not check for file types etc.

Did cd /etc and then things of the form grep -R "cyclades" rc0.d/*.

Got not hits. Getting blerry-eyed, tired, and hungry. Must consume calories and snooze.

Chances are that youw won't find it by looking rc0.d , that being the HALT runlevel. I would look under /etc/rc.d/init.d specifically. Or comb the entire /etc since it usually isn't too big for a recursive grep to comeback in under 20-30 seconds.

Finally got to work on this Cyclades pain some more. Found a much of different cyclades.o files that apparently get generated automatically each time I use RedHat Network to update my kernel. When I do modprobe -c, I see

alias char-major-19 cyclades
alias char-major-20 cyclades

cat /etc/modules.conf yields many fewer lines - a bunch of blank ones and then some stuff having to do mainly with sound drivers.

In addition to the module files, there is an include file and a Perl script. Doing rpm -qf on the modules (RH 8) and other two files doesn't give anything useful in finding a package that installed the cyclades modules in the first place.

I still haven't found anything that tells me how to permanently prevent the module from loading on boot for the current kernel. How can I do this?

Looks like I need to find some kind of kernel configuration file to ensure that the module does not get built for future kernels. Pointers? Clues for the clueless?
