How to ssh connect through python Paramiko with ppk public key
i'm using Paramiko to connect through ssh to a server.
Basic authentication works well, but i can't understand how to connect with public key.
When i connect with putty, the server tell me this:
Using username "root".
Authenticating with public key "[email protected]"
Passphrase for key "[email protected]": [i've inserted the passphrase here]
Last login: Mon Dec 5 09:25:18 2011 from ...
I connect to it with this ppk file:
PuTTY-User-Key-File-2: ssh-rsa
Encryption: aes256-cbc
Comment: [email protected]
Public-Lines: 4
[4 lines key]
Private-Lines: 8
[8 lines key]
Private-MAC: [hash]
With basic auth the error i get (from the log) is:
DEB [20111205-09:48:44.328] thr=1 paramiko.transport: userauth is OK
DEB [20111205-09:48:44.927] thr=1 paramiko.transport: Authentication type (password) not permitted.
DEB [20111205-09:48:44.927] thr=1 paramiko.transport: Allowed methods: ['publickey', 'gssapi-with-mic']
I've tried to include that ppk file and set to auth_public_key, but didn't work.
Can you help me?

Ok @Adam and @Kimvais were right, paramiko cannot parse .ppk files.
So the way to go (thanks to @JimB too) is to convert .ppk file to openssh private key format; this can be achieved using Puttygen as described here.
Then it's very simple getting connected with it:
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('<hostname>', username='<username>', password='<password>', key_filename='<path/to/openssh-private-key-file>')
stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
ssh.close()
