When I boot the system I am getting this error message in /var/log/boot.log Dec 19 11:50:03 ns1 sysctl: error: 'net.ipv4.ip_always_defrag' is an unknown key Dec 19 11:57:16 ns1 random: Initializing random number generator: succeeded Dec 19 11:50:03 ns1 sysctl: net.ipv4.ip_forward = 1 Dec 19 11:50:03 ns1 sysctl: net.ipv4.conf.all.rp_filter = 1 Dec 19 11:50:03 ns1 sysctl: kernel.sysrq = 0 Dec 19 11:50:03 ns1 rc.sysinit: Configuring kernel parameters: succeeded
It disappeared between the 2.2 and 2.4 kernel. Did you do an upgrade or a fresh install?
I did manual upgrade on my 7.0 system with most upto date updates from /pub/updates/redhat/7.0/i386/ installed. rpm -ivh kernel-smp*rpm and switched the boot to new kernel.
if you have a 2.4 kernel, then just remove it from /etc/sysctl.conf
