2. 对方端口未打开,发生在连接建立 如果端口打开,只是sync_backlog满了的话,sync简单被丢弃,表现为超时,而不会rst。 3. close Socket 时recv buffer 不为空 例如,客户端发了两个请求,服务器只从buffer 读取第一个请求处理完就关闭连接,tcp层认为数据没有正确提交到应用,使用rst关闭连接。 3. 移动链路 移动网...

ICMP is used by a device, often a router, to report and acquire a wide range of communications-related information.
主要的不同就是No response seen,你可以检验一下上一小节的请求包。 8. Examine the ICMP error packet in your screenshot. It has more fields than the ICMP echo packet. What is included in those fields? 可以看到在错误包的IMCP中包含了原始IP和上层端口号ICMP的信息。
No response to multiple traffic– an ICMP message can’t be sent in response to traffic that comes from multicasts, broadcasts, loopbacks, or invalid addresses No guarantee of delivery– as we have seen in examples above, some administrators might consider them to be a nuisance and configure...
I find it intresting the docker network gateway response works but not outside. However interesting that may be the test code fails in the Ping class at the docker gateway address hop 1. So that may be a red herring. # traceroute -I 8.8.8.8 traceroute to 8.8.8.8 (8.8.8.8), 30 hops...
