nf_conntrack_ipv4_compat_init() --> register_pernet_subsys() --> ip_conntrack_net_init() 创建/proc文件ip_conntrack和ip_conntrack_expect nf_conntrack_in 分析: /*conntrack的工作主要是: 1. 由skb得到一个tuple,对数据包做合法性检查。 2. 查找net->ct.hash表是否已记录这个tuple。如果没有记录,...
运行状态中通过 sysctl net.netfilter.nf_conntrack_buckets 进行查看,通过文件 /sys/module/nf_conntrack/parameters/hashsize 进行设置 或者新建 /etc/modprobe.d/iptables.conf ,重新加载模块才生效: options nf_conntrack hashsize = 262144 1. 3、还有些相关的系统参数`sysctl -a | grep nf_conntrack`可以调优(...
