Curl --interface 问题

我尝试为 curl 指定无线接口，但有些事情无法正常工作。

当局域网电缆断开时，它可以按预期工作。当局域网电缆插入时，连接超时。

参见下面的日志，首次尝试插入局域网电缆。

您可能需要使用--dns-interface。

来自手册页：

--dns-interface <interface>
       Tell curl to send outgoing DNS requests through <interface>. This option is a counterpart to --interface (which does not affect DNS).
       The supplied string must be an interface name (not an address).
