Hello,

I think I'll need to install a newer version of IPtables for my CentOS 5.6 since I updated the kernel to 2.6.32.41 and iptables-1.4.6 seems to be the older version that matches this kernel but CentOS 5.6 is shipped with 1.3.5 (this distro and it's 10 years old packages is starting to bore me...).

So I need to update iptables but I don't find good howtos on this subject...

So my question would be : how to build iptables from source and does it change anything to the procedure that I already have 1.3.5 installed ?

Hi there,

When you say you want to install iptables from source, do you have the source RPM?

Also you can update iptables using yum update iptables. I would suggest you to backup your iptables configuration file before doing this. You can find out iptables configuration file using: rpm -qc iptables

boring = stable. Why do you want the newer versions? What can't you do with the "old" release? Note that all relevant security and bugfixes will have been back ported to it...

Hello,
I can't yum update it, since 1.3.5 is the "newer" in the CentOS repos. I don't know much about RPMs usually I compile things with "make" and that kind of stuff, I was planing on using that file http://www.netfilter.org/projects/ip...4.11.1.tar.bz2 as a source.

You're indeed right on the boring = stable. Now I'm not sure I need the newer version, although I read that there are incompatibilities between old iptables and more recent kernels. Right now I have a problem that has to do with my kernel config, at least that's what I think, after fixing it I'll see if iptables runs fine, I hope it will but I'm getting ready for the worst.
