    Hello there,

    I have recently ordered a new dedicated server from Ezzi.net, it's great. I've just got this one and VERY annoying problem. It seems that iptables has messed up after I did a kernel upgrade.

    I get the following error in an email about every 5 minutes:

    iptables v1.2.11: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
    Perhaps iptables or your kernel needs to be upgraded.

    These keep coming and coming, I've tried updates and other stuff, tried Google and did searching, didn't really find anything that would lead me in the right direction to get this resolved. I am currently running an AMD Athlon64 3000+ with Centos 4.3, kernel version is 2.6.16.16.

    If anyone has any information or any solution for this problem I would be greatly appreciative. Thank you in advanced.

    Go on, have a guess
    Are you using the kernel that comes with CentOS? If not and it's a custom kernel, then you need to enable all the netfilter options when you build the kernel to be sure that the iptables modules are all available.

    No, it's not the default kernel that CentOS comes with. It is indeed a custom one I built my self because the default kernel has bugs managing memory. Thanks, I am looking at the options now. :)

    Any suggestions on a kernel that is custom built, every netfilter option was set to M and the monolithic is enabled? Everything except bandmin works, this is all I am getting errors on.

    I can only suggest building a kernel with LKM support instead of a monolithic one and doing it that way to ensure the modules you need are loaded as needed. I've not had a problem myself with iptables when building a kernel, but you do have to check down at least two tree's, IIRC, for netfilter options on the latest kernels. Can't remember them off-hand I'm afraid.
