It seems the socket connection through paramiko (v1.10.0) is not stable.
I have two computers. The python code is on the PC one. The connection sometime is successful and sometime is not (Same code). When the PC paramiko code fails (socket.error, 10060), I use my Mac via terminal ssh login the server and everything is fine.
I use set_missing_host_key_policy in the code. But the Mac has the key I guess. I typed yes when login at the first time.
If the unstable connection is caused by the hotkey, how do I get the host key? From the server or somewhere in my local folder (win7)?
