问题
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
回答1:
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
回答2:
The paramiko.RSAKey.from_private_key_file method requires the private key file to be in "PEM" format. Examine the file you're trying to read and see if it begins with a line that says:
-----BEGIN RSA PRIVATE KEY-----
If it doesn't have that line then it's not PEM.
If it's not PEM then you'll have to find some way to create a PEM version of the private key. (EDIT: the original poster used PuTTY's puttygen utility to export the private key into a PEM-format file.)
Make sure that the new file has the same ownership and limited access permissions that the original id_rsa file has, so that nobody can steal the key by reading the file. Then, obviously, modify your paramiko call to read the key from the new PEM-format file.
