python paramiko模块ftp报错：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/paramiko/sftp_client.py", line 170, in from_transport
return cls(chan)
File "/usr/lib/python2.7/dist-packages/paramiko/sftp_client.py", line 132, in __init__
raise SSHException("EOF during negotiation")
paramiko.ssh_exception.SSHException: EOF during negotiation
解决方案：
sftp服务问题：
首先，查找sftp-server安装位置，find / -name sftp-server
然后，vim /etc/ssh/sshd_config ，查看sftp路径是否正确，修改。
最后重启sshd： systemctl restart sshd
