_CommandTransport
is an SSH client transport which includes a host key verification
step before it will proceed to secure the connection.
_CommandTransport
also knows how to set up a connection to an authentication agent if it is
told where it can connect to one.
| Method | __init__ | |
| Method | verifyHostKey | Ask the KnownHostsFile
provider available on the factory which created this protocol this protocol
to verify the given host key. |
| Method | connectionSecure | When the connection is secure, start the authentication process. |
| Method | connectionLost | When the underlying connection to the SSH server is lost, if there were any connection setup errors, propagate them. Also, clean up the connection to the ssh agent if one was created. |
| Instance Variable | _userauth | The _UserAuth
instance which is in charge of the overall authentication process or
None if the SSH connection has not reach yet the
user-auth service. (type: _UserAuth) |
| Method | _saveHostKeyFailure | When host key verification fails, record the reason for the failure in
order to fire a Deferred with
it later. |
Inherited from BaseProtocol (via SSHClientTransport, SSHTransportBase, Protocol):
| Method | makeConnection | Make a connection to a transport and a server. |

| Parameters | creator | The _NewConnectionHelper
that created this connection. (type: _NewConnectionHelper.) |
Ask the KnownHostsFile
provider available on the factory which created this protocol this protocol
to verify the given host key.
| Returns | A Deferred
which fires with the result of KnownHostsFile.verifyHostKey. | |
When the connection is secure, start the authentication process.
When the underlying connection to the SSH server is lost, if there were any connection setup errors, propagate them. Also, clean up the connection to the ssh agent if one was created.
