RPyC SSH连接

Question

我正在尝试使用RPyC在google上的2个VM实例之间建立一个客户机-服务器连接。我有以下代码：

服务器端：

import rpyc

class MyService(rpyc.Service):
    def on_connect(self):
        # code that runs when a connection is created
        # (to init the serivce, if needed)
        pass

    def on_disconnect(self):
        # code that runs when the connection has already closed
        # (to finalize the service, if needed)
        pass

    def exposed_get_answer(self): # this is an exposed method
        return 42

    def get_question(self):  # while this method is not exposed
        return "what is the airspeed velocity of an unladen swallow?"

if __name__ == "__main__":
        from rpyc.utils.server import ThreadedServer
        from rpyc.utils.authenticators import SSLAuthenticator
        authenticator = SSLAuthenticator("myserver.key", "myserver.cert")
        server = ThreadedServer(MyService, port=12345, authenticator=authenticator)
        server.start()

客户端：

import rpyc

conn = rpyc.ssl_connect("myserver", port = 12345, keyfile=None,
                        certfile=None)
conn.execute("print ('world')")

当我运行Client.py时，我会得到以下错误

socket.gaierror: Errno -3名称解析的临时失败

我认为这与keyfile和certfile有关，但我不知道如何设置它们。有什么想法吗？谢谢!

Answer 1

GAIERROR：Get A Info Error

当名称解析失败时，会出现此错误。

如果两台机器都是Linux，则在/etc/hosts文件中添加条目，或者将"myserver“替换为IP地址。

Answer 2

检查名称"myserver“是否可访问，否则将其替换为IP地址。
