Hi,

I am running a Linode server (Ubuntu 10.04 LTS). There are two linux kernel modules, which are creating problem and not required by use. Modules are listed below:

nf_nat_sip
nf_conntrack_sip

Is there any one who can help me to remove these kernel functions. or Should i recompile the kernel again.


Thanks in advance for any help.

What you need is to "blacklist module". Search for that

PD: you can unload them now using "modprobe -r module_name". To prevent loading on boots, you have to blacklist them.

Thanks for reply. There are many files in /etc/modprob.d/ directory, as listed:

blacklist-ath_pci.conf
blacklist.conf
blacklist-firewire.conf
blacklist-framebuffer.conf
blacklist-watchdog.conf

Where should i make the entry of the module to disable it. Will the change take effect by making entry to the file. I have tried it in blacklist.conf file. But zcat /proc/config.gz tells that these modules are loaded.

I request to community members to help me.

All files under /etc/modprobe.d/ are processed on boot (this is why you see modules still loaded). You can edit one of them or add a new one.

To unload those modules without reboot, you can do "sudo modprobe -r nf_nat_sip" and "sudo modprobe -r nf_conntrack_sip". This is only valid until next reboot (you have to blacklist them to make it permanent).
