Paramiko example using private key

paramiko_example.py

import paramiko
k = paramiko.RSAKey.from_private_key_file("/Users/whatever/Downloads/mykey.pem")
c = paramiko.SSHClient()
c.set_missing_host_key_policy(paramiko.AutoAddPolicy())
print "connecting"
c.connect( hostname = "www.acme.com", username = "ubuntu", pkey = k )
print "connected"
commands = [ "/home/ubuntu/firstscript.sh", "/home/ubuntu/secondscript.sh" ]
for command in commands:
	print "Executing {}".format( command )
	stdin , stdout, stderr = c.exec_command(command)
	print stdout.read()
	print( "Errors")
	print stderr.read()
c.close()

socket.py", line 918, in getaddrinfo for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 11001] getaddrinfo failed
what's wrong

Not working for me, while use the key using ssh client it works

Traceback (most recent call last):

Converting the key
resolves the error
ssh-keygen -p -m PEM -f ~/.ssh/id_rsa

thanks.
if your private key is in .ppk, you need convert to .pem.

I resolve this problem with version paramiko-2.10.4
