A Channel is meant to behave like a socket, and has an API that should be indistinguishable from the Python socket API. Because SSH2 has a windowing kind of flow control, if you stop reading data from a Channel and its buffer fills up, the server will be unable to send you any more data until you read some of it. (This won't affect other channels on the same transport -- all channels on a single transport are flow-controlled independently.) Similarly, if the server isn't reading data you send, calls to `send` may block, unless you set a timeout. This is exactly like a normal network socket, so it shouldn't be too surprising. Instances of this class may be used as context managers. c C s3 | | _ d | _ d | _ t | _ d | _ d | _ t � | _ t � | _ d | _ t | _ t | _ t j � | _ t j | j � | _ d | _ d | _ d | _ d | _ d | _ d | _ t j � | _ t | � | _ t j d � | _ d | _ t j � | _! t | _" t | _# d | _$ d | _% d S( sm Create a new channel.

If the server allows it, further x11 requests can be made from the server to the client, when an x11 application is run in a shell session. From :rfc:`4254`:: It is RECOMMENDED that the 'x11 authentication cookie' that is sent be a fake, random cookie, and that the cookie be checked and replaced by the real cookie when a connection request is received. If you omit the auth_cookie, a new secure random 128-bit value will be generated, used, and returned. You will need to use this value to verify incoming x11 requests and replace them with the actual local x11 cookie (which requires some knowledge of the x11 protocol). If a handler is passed in, the handler is called from another thread whenever a new x11 connection arrives. The default handler queues up incoming x11 connections, which may be retrieved using `.Transport.accept`. The handler's calling signature is:: handler(channel: Channel, (address: str, port: int)) :param int screen_number: the x11 screen number (0, 10, etc.) :param str auth_protocol: the name of the X11 authentication method used; if none is given, ``"MIT-MAGIC-COOKIE-1"`` is used :param str auth_cookie: hexadecimal string containing the x11 auth cookie; if none is given, a secure random 128-bit value is generated :param bool single_connection: if True, only a single x11 connection will be forwarded (by default, any number of x11 connections can arrive over this session) :param function handler: an optional handler to use for incoming X11 connections :return: the auth_cookie used s MIT-MAGIC-COOKIE-1i s x11-reqN( R! t binasciit hexlifyt ost urandomR RH R RI R RJ RK RL RN R" RO RP t _set_x11_handler( R t screen_numbert auth_protocolt auth_cookiet single_connectiont handlerRV ( ( s4 /usr/lib/python2.7/site-packages/paramiko/channel.pyt request_x11� s$ ) c C sd t � } | j t � | j | j � | j d � | j t � | j j | � | j j | � t S( sx Request for a forward SSH Agent on this channel.

The default is ``False``, but in some cases it may be convenient to have both streams combined. If this is ``False``, and `exec_command` is called (or ``invoke_shell`` with no pty), output to stderr will not show up through the `recv` and `recv_ready` calls.

An EOF condition is considered "immediate data" for `recv`, so if the channel is closed in the read direction, it will never block. ``chan.setblocking(0)`` is equivalent to ``chan.settimeout(0)``; ``chan.setblocking(1)`` is equivalent to ``chan.settimeout(None)``. :param int blocking: 0 to set non-blocking mode; non-0 to set blocking mode. g N( R� R!
