Class Packetizer

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__

(inherited documentation)

Returns ``True`` if a new set of keys needs to be negotiated. This will be triggered during a packet read or write, so it should be checked after every read or write, or at least after every few.

Turn on/off the callback keepalive. If ``interval`` seconds pass with no data read from or written to the socket, the callback will be executed and the timer will be reset.

Read as close to N bytes as possible, blocking as long as necessary.

:param int n: number of bytes to read
:return: the data read, as a `str`

:raises EOFError:
    if the socket was closed before all the bytes could be read

Read a line from the socket. We assume no data is pending after the line, so it's okay to attempt large reads.

Only one thread should ever be in this function (no other locking is done).

:raises SSHException: if the packet is mangled :raises NeedRekeyException: if the transport should rekey
