As far as I'm aware, centos have never shipped a 2.6.35 kernel with any release, and that's the sort of error you get with a openVZ "stab" (or Stable) kernel, where unless the host provides you with the modules, there's not a lot you can do about it. > <snip> > > Appreciate suggestions on how to get kernel 2.6.35.4 to install the > whole IP tables package, especially the STRING and RECENT options (in > -m). Perhaps you might want to talk to your hosting company about what they're selling you, because it certainly isn't a 'pure' centos install. Steve.
