I am trying connect to server using following spinet

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ip = ['x.x.x.x']
key_file = "/Users/user/.ssh/id_rsa"

key = paramiko.RSAKey.from_private_key_file(key_file)
ssh.load_system_host_keys()
ssh.connect(ips, port=22, username='XYZ', pkey=key, timeout=11)

But I am getting an error:

not a valid RSA private key file

I faced a similar situation and ssh-keygen comes to my help. You should make a copy of id_rsa and convert it to RSA type with ssh-keygen.

To Convert "BEGIN OPENSSH PRIVATE KEY" to "BEGIN RSA PRIVATE KEY"

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa
