当我运行我的Python脚本时,我在paramiko 库上遇到错误......
但是脚本的结果不理解。任何人都可以帮助解决这个问题..!?
这是错误:
**Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/paramiko/transport.py", line 2044, in _check_banner
buf = self.packetizer.readline(timeout)
File "/usr/local/lib/python3.5/dist-packages/paramiko/packet.py", line 353, in readline
buf += self._read_timeout(timeout)
File "/usr/local/lib/python3.5/dist-packages/paramiko/packet.py", line 540, in _read_timeout
x = self.__socket.recv(128)
ConnectionResetError: [Errno 104] Connection reset by peer
在处理上述异常的过程中,我遇到了另一个异常
这是新的异常:
Traceback (most recent call last):
