![端口 22:连接被拒绝,但只有 60% 的时间](https://linux22.com/image/955046/%E7%AB%AF%E5%8F%A3%2022%EF%BC%9A%E8%BF%9E%E6%8E%A5%E8%A2%AB%E6%8B%92%E7%BB%9D%EF%BC%8C%E4%BD%86%E5%8F%AA%E6%9C%89%2060%25%20%E7%9A%84%E6%97%B6%E9%97%B4.png)
我正在运行这个:
ssh_command = f'ssh -vvv -o StrictHostKeyChecking=no -i {private_key_file} ubuntu@{public_ip}'
# Use os.system to execute the SSH command in a subshell
os.system(ssh_command)
但是,这只有 40% 的时间有效。我见过的所有调试要么 100% 有效,要么 100% 无效。据我所知,我的连接性并不不稳定。我正在 ssh 进入 EC2。
我经常会收到这个错误:
OpenSSH_9.4p1, LibreSSL 3.3.6

我使用的是 MacOS 14.2.1,但正在通过 ssh 连接到 Ubuntu 服务器。当我手动 ssh 时,没有遇到任何问题。
