7212 time wait sockets recycled by time stamp 虽然叫做 TWRecycled 但实际它指的是 reuse 的连接数,不是下面要说的 recycled 的连接数。其反应的是 LINUX_MIB_TIMEWAITRECYCLED 这个计数,在__inet_check_established 内 reuse TIME WAIT 连接后计数 net.ipv4.tcp_tw_recycle 该配置也是要基于 TCP Timestamp,...

假设主动关闭方跳过TIME_WAIT状态或者处于TIME_WAIT状态很短的时间后进入CLOSED状态,此时主动关闭方如果使用相同的源端口,发起SYN建连请求,被动关闭方由于还处于LAST_ACK状态,收到SYN包,此时就会回复RST包,导致新连接无法正常建立起来。 2、 新的TCP连接被建立起来了,延迟包可能干扰新的连接 当使用原来的五元组来建立...
To achieve high performance, the TCP timestamp option is enabled by default in general Linux versions. If this option is disabled, the quick reclaiming function of TCP time-wait sockets (net.ipv4.tcp_tw_recycle) will be invalid. This low-risk vulnerability may have the following impact: Attac...
SLB on TIME_WAIT. For the client, if the TCP kernel parameters tcp_tw_recycle and tcp_timestamps are both set to 1, normally the sockets in the TIME_WAIT status will be quickly recycled. But the current phenomenon is that the sockets in the TIME_WAIT status is not quickly recycled. ...
