Additional info:
Problem is fixed in paramiko 1.15.1
https://github.com/paramiko/paramiko/issues/423

1. First check the Version of openSSH and python .

command to check openSHH version is :

On linux : ssh -v

Command to check paramiko version :

 .>>> import paramiko
>>> print paramiko.__version__
1.12.0

2. if your paramiko lib version is lower than 1.15.1 and openshh is higher than 6.7 , you have in problem .

Solution :

1) downgrade the openSHH version to below 6.7 .

or 

2) Upgrade the paramiko lib version to above 1.15.1

check your current python version when you upgrade the paramiko lib version .
