Based on RFC 854: TELNET Protocol Specification, by J. Postel and J. Reynolds Example: >>> from telnetlib import Telnet >>> tn = Telnet('www.python.org', 79) # connect to finger port >>> tn.write('guido\r\n') >>> print tn.read_all() Login Name TTY Idle When Where guido Guido van Rossum pts/2 snag.cnri.reston.. >>> Note that read_all() won't read until eof -- it just reads some data -- but it guarantees to read at least one byte unless EOF is hit. It is possible to pass a Telnet object to select.select() in order to wait until more data is available. Note that in this case, read_eager() may return '' even if there was data on the socket, because the protocol negotiation may have eaten the data. This is why EOFError is needed in some cases to distinguish between "no data" and "connection closed" (since the socket also appears ready for reading when it is closed). To do: - option negotiation - timeout should be intrinsic to the connection object instead of an option on one of the read calls only i��NtTelnetiii�i�i�i�i�i�i�i�i�i�i�i�i�i�i�i�iiiiiiiii i iii iiiiiiiiiiiiiiiiii i!i"i#i$i%i&i'i(i)i*i+i,i-i.i/i0i1i�i�i�cBs@eZdZd dejd�Zdejd�Zd�Zd�Z d�Z d�Zd�Zd �Z d �Zd d�Zd�Zd d �Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Zd�Z d d�Z!d d�Z"d d�Z#RS(!s�Telnet interface class. An instance of this class represents a connection to a telnet server. The instance is initially not connected; the open() method must be used to establish a connection. Alternatively, the host name and optional port number can be passed to the constructor, too. Don't try to reopen an already connected instance. This class has many read_*() methods. Note that some of them raise EOFError when the end of the connection is read, because they can return an empty string for other reasons. See the individual doc strings. read_until(expected, [timeout]) Read until the expected string has been seen, or a timeout is hit (default is no timeout); may block. read_all() Read all data until EOF; may block. read_some() Read at least one byte or EOF; may block. read_very_eager() Read all data available already queued or on the socket, without blocking. read_eager() Read either data already queued or some data available on the socket, without blocking. read_lazy() Read all data in the raw queue (processing it first), without doing any socket I/O. read_very_lazy() Reads all data in the cooked queue, without doing any socket I/O. read_sb_data() Reads available data between SB ... SE sequence. Don't block. set_option_negotiation_callback(callback) Each time a telnet option is read on the input flow, this callback (if set) is called with the following parameters : callback(telnet socket, command, option) option will be chr(0) when there is no option. No other action is done afterwards by telnetlib. icCs�t|_||_||_||_d|_d|_d|_d|_ d|_ d|_d|_d|_ d|_ttd�|_|dk r�|j|||�ndS(s�Constructor. When called without arguments, create an unconnected instance.
