IPV6 套接字的本地地址不在接口上

Question

创建 TCP6 套接字并连接到服务器时，为套接字选择的本地地址不在主机的任何接口上。为什么不同？

在下面的示例中，主机的 eth0 IPV6 地址是 fe80::10ff:36ff:fef5:611d。由于客户端是从 fe80::10ff:36ff:fef5:611d%eth0 连接的，我希望套接字的本地地址是相同的。但是 netstat 显示它是 fe80::10ff:36ff:f.

$ nc -l6v :: 10023
Listening on :: 10023
Connection received on fe80::10ff:36ff:fef5:611d%eth0 37402

$ nc -v fe80::10ff:36ff:fef5:611d%eth0 10023
Connection to fe80::10ff:36ff:fef5:611d%eth0 10023 port [tcp/*] succeeded!

$ netstat -6tn
Active Internet connections (w/o servers)

Answer 1

地址被截断。尝试将 netstat 与 -l

一起使用
