python - Python sshtunnel-如何验证SSH连接？

Question

使用Python，在执行以下操作后如何验证SSH连接是否成功:

server = SSHTunnelForwarder(
    (host_or_ip, 22),
    ssh_username = "ssh_username",
    ssh_private_key = path_to_key,
    remote_bind_address = (another_host_or_ip, 5432)
)

server.start()

Answer 1

我用它来查看隧道是否打开:

server.skip_tunnel_checkup = False
server.start()
server.check_tunnels()
print(server.tunnel_is_up, flush=True)

在日志中，您将看到:

{('0.0.0.0', 44004): True}  # this tunnel is up
{('0.0.0.0', 44004): False}  # this tunnel is not up
