I'm trying to do ssh through middle server with python.

I tried to work as written at this example : SSH to machine through a middle host

but when I'm running the code, I'm getting the following exception paramiko.ssh_exception.SSHException: Error reading SSH protocol banner When I'm opens the terminal that executes the program password authentication is required in order to proceed

I also edited the ~/.ssh/config as follows:

Host cybnode13
        ProxyCommand  ssh root@cybhead1.lnx.biu.ac.il nc %h %p

My code is attached below

proxy_command = 'ssh -p %s %s@%s nc %s %s' % (password, proxy_user, proxy_host, host, 22)

proxy = paramiko.ProxyCommand(proxy_command)


client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(host, username=proxy_user, password=password, sock=proxy)

stdin, stdout, stderr = client.exec_command('echo HELLO')

What's your Python version? There was issue https://github.com/paramiko/paramiko/issues/673 on Python 3 – Samuel Dec 11 '16 at 13:18
@Samuel I'm using python 3.5, but the error exists when I'm using python 2.7 also – liorko Dec 11 '16 at 13:32
And what is Paramiko version? – Samuel Dec 11 '16 at 13:48
2.1.0 for python 2.7 and python 3.5 – liorko Dec 11 '16 at 13:54
Check if [this](http://stackoverflow.com/a/29225295/524743) answer helps – Samuel Dec 11 '16 at 14:01
Unfortunately it doesn't helps. I made some changes to ~/.ssh/config and update the question details. – liorko Dec 13 '16 at 08:11
