This only creates the Transport object; it doesn't begin the SSH session yet. Use L{connect} or L{start_client} to begin a client session, or L{start_server} to begin a server session. If the object is not actually a socket, it must have the following methods: - C{send(str)}: Writes from 1 to C{len(str)} bytes, and returns an int representing the number of bytes written. Returns 0 or raises C{EOFError} if the stream has been closed. - C{recv(int)}: Reads from 1 to C{int} bytes and returns them as a string. Returns 0 or raises C{EOFError} if the stream has been closed. - C{close()}: Closes the socket. - C{settimeout(n)}: Sets a (float) timeout on I/O operations. For ease of use, you may also pass in an address (as a tuple) or a host string as the C{sock} argument. (A host string is a hostname with an optional port (separated by C{":"}) which will be converted into a tuple of C{(hostname, port)}.)

It's a rather obscure option and can be safely ignored. In server mode, the remote client may request "group-exchange" key negotiation, which asks the server to send a random prime number that fits certain criteria. These primes are pretty difficult to compute, so they can't be generated on demand. But many systems contain a file of suitable primes (usually named something like C{/etc/ssh/moduli}). If you call C{load_server_moduli} and it returns C{True}, then this file of primes has been loaded and we will support "group-exchange" in server mode.

This is a shortcut for L{start_client}, L{get_remote_server_key}, and L{Transport.auth_password} or L{Transport.auth_publickey}. Use those methods if you want more control. You can use this method immediately after creating a Transport to negotiate encryption with a server. If it fails, an exception will be thrown. On success, the method will return cleanly, and an encrypted session exists. You may immediately call L{open_channel} or L{open_session} to get a L{Channel} object, which is used for data transfer. @note: If you fail to supply a password or private key, this method may succeed, but a subsequent L{open_channel} or L{open_session} call may fail because you haven't authenticated yet. @param hostkey: the host key expected from the server, or C{None} if you don't want to do host key verification. @type hostkey: L{PKey} @param username: the username to authenticate as. @type username: str @param password: a password to use for authentication, if you want to use password authentication; otherwise C{None}. @type password: str @param pkey: a private key to use for authentication, if you want to use private key authentication; otherwise C{None}. @type pkey: L{PKey} @raise SSHException: if the SSH2 negotiation fails, the host key supplied by the server is incorrect, or authentication fails. sBad host key from serversExpected: %s: %ssGot : %s: %ssHost key verified (%s)sAttempting password auth...sAttempting public-key auth...N( RURR.RRRsRRR(Rt auth_passwordtauth_publickey(R%thostkeytusernametpasswordtpkeyR((sQC:\Documents and Settings\red08xgu\Desktop\python_webupdate\paramiko\transport.pyR{s$"    2,, cCs<|iiz|i}d|_|SWd|iiXdS(s} Return any exception that happened during the last server request.

A handler is used to answer arbitrary questions from the server. On many servers, this is just a dumb wrapper around PAM. This method will block until the authentication succeeds or fails, peroidically calling the handler asynchronously to get answers to authentication questions. The handler may be called more than once if the server continues to ask questions. The handler is expected to be a callable that will handle calls of the form: C{handler(title, instructions, prompt_list)}. The C{title} is meant to be a dialog-window title, and the C{instructions} are user instructions (both are strings). C{prompt_list} will be a list of prompts, each prompt being a tuple of C{(str, bool)}. The string is the prompt and the boolean indicates whether the user text should be echoed. A sample call would thus be: C{handler('title', 'instructions', [('Password:', False)])}. The handler should return a list or tuple of answers to the server's questions.
