无法通过 macOS 笔记本电脑连接到 Raspberry Pi。可通过其他设备连接

无法通过 MacOS 笔记本电脑连接到 Raspberry Pi。可通过包括 Linux 和 iOS 在内的其他设备工作。

这是 macOS 终端命令和输出：

ssh -vvvvvv -p 9091 [email protected]
OpenSSH_8.8p1, OpenSSL 1.1.1m  14 Dec 2021
debug1: Reading configuration data /usr/local/etc/ssh/ssh_config

从我看到的 PI

error: kex_exchange_identification: Connection closed by remote host
Connection closed by 192.168.1.107: port 63461

答案1

调试日志表明，即使在通过 TCP 连接发送任何 SSH 特定数据之前，TCP 连接也因某种原因失败。您可以尝试使用命令禁用连接超时。如果此方法不起作用，请尝试使用 WireShark 分析 MAC 到 PI 的 TCP 连接失败的原因。ssh -vvvvvv -o ConnectTimeout=0 -p 9091 [email protected]

要检查是否可以从 MAC 到 PI 建立 TCP 连接，您可以尝试，telnet 192.168.1.103 9091如果成功，您将看到类似以下内容：

bash> telnet 192.168.1.103 9091
Trying 192.168.1.103...
Connected to 192.168.1.103.
Escape character is '^]'.
