I have the this error when I run sysctl -p in Debian 5.0.8.

error: "net.netfilter.nf_conntrack_acct" is an unknown key

My sysctl configuration

net.netfilter.nf_conntrack_acct = 1
net.ipv4.netfilter.ip_conntrack_max = 9527600
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 7200

Output of lsmod

Well, it's saying that you have a setting net.netfilter.nf_conntrack_acct in your /etc/sysctl.conf, but when sysctl tries to load that setting it has no idea what it is. Did this used to work in the past? Maybe you installed a new kernel which does not support that sysctl.

EDIT: based on your comment about the kernel version you are using, it looks like your older Debian does not support that sysctl. See this debian mailing list thread for details - looks like it was added in 2.6.29.

You will have to recompile your kernel or upgrade to enable that feature.
