如何在 ~/.ssh/config 中使用带有主机定义的 Paramiko?

How to use Paramiko with host definition in ~/.ssh/config?

对于我的 SSH 连接,我使用这个 ~/.ssh/config:

Host gwhost
Hostname gw.hostname.com
User user
IdentityFile /home/user/.ssh/priv_key
ControlMaster auto
ControlPath ~/.ssh/%h-%p-%r.sock
ControlPersist 120

Host *.my-example.com
User user
IdentityFile /home/user/.ssh/priv_key
StrictHostKeyChecking no
ProxyCommand ssh -q 'gwhost' -W %h:22

我可以像这样从终端连接到主机:

ssh one.my-example.com

我想使用 Paramiko 在远程主机上执行一些命令。 我试着这样做:

host = 'one.my-example.com'
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
user_config_file = os.path.expanduser("~/.ssh/config")
config = SSHConfig.from_path(user_config_file)

ssh.connect(hostname=host)
stdin, stdout, stderr = ssh.exec_command('ls')
lines = stdout.readlines()
print(lines)

启动后出现这个错误

in <lambda>
    retry_on_signal(lambda: sock.connect(addr))
TimeoutError: [Errno 110] Connection timed out

那么我该如何使用 ~/.ssh/config 或者我不应该 ~/.ssh/config

Paramiko 只有 very limited support for OpenSSH ssh_config configuration file.

If 肯定不会像 OpenSSH ssh 那样自动使用 ssh_config

您必须使用 SSHConfig.from_path. And then use SSHConfig.lookup to lookup configuration for your hostname. And then use the returned dictionary to feed the arguments of SSHClient.connect.

实例化 SSHConfig class

强制性警告:请勿使用 AutoAddPolicy – 您正在失去针对 MITM attacks by doing so. For a correct solution, see Paramiko "Unknown Server".
