Ossec insmod error

Let me preface this by saying that if you are not running Ossec on at least your external facing machines, then you should be. It’s great software!

The reason this post is here is for reference mostly and maybe to be able to help someone out later via their favorite search engine.

I have been getting a couple errors reported lately through Ossec emails that report: “insmod: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg”. Well, after checking, the actual error is found in /var/log/messages and is “floppy.o: init_module: No such device”. AHA! Well, it just so happens that these machines are servers *with no floppy*. The fix for this to turn off the errors seems to be to add “alias floppy off” in the /etc/modules.conf file and then run a “depmod -a”.
