Module provides class BaseClient.
BaseClient(shell=None, log=None, loop=None, encoding='utf8', encoding_errors='strict', force_binary=False, connect_minwait=1.0, connect_maxwait=4.0, limit=None, waiter_closed=None, _waiter_connected=None)¶
Base Telnet Client Protocol.
Begin on-connect negotiation.
A Telnet client is expected to send only a minimal amount of client session options immediately after connection, it is generally the server which dictates server option support.
Deriving implementations should always call
Callback, return whether negotiation is complete.
Parameters: final¶ (bool) – Whether this is the final time this callback will be requested to answer regarding protocol negotiation. Returns: Whether negotiation is over (client end is satisfied). Return type: bool
Method is called on each new command byte processed until negotiation is considered final, or after
connect_maxwaithas elapsed, setting
This method returns False until
connect_minwaithas elapsed, ensuring the server may batch telnet negotiation demands without prematurely entering the callback shell.
super().check_negotiation()is called and conditionally combined when derived.
Called when the connection is lost or closed.
Parameters: exc¶ (Exception) – exception.
Noneindicates a closing EOF sent by this end.
Called when a connection is made.
super().connection_made(transport)is called when derived.
Process bytes received by transport.
Time elapsed since client connected, in seconds as float.
Encoding that should be used for the direction indicated.
The base implementation always returns
default_encodingor, when unspecified,
Called when the other end calls write_eof() or equivalent.
Get optional client protocol or transport information.
Time elapsed since data last received, in seconds as float.
