twisted.conch.telnet.AuthenticatingTelnetProtocol(StatefulTelnetProtocol) class documentationtwisted.conch.telnet
View Source
(View In Hierarchy)
A protocol which prompts for credentials and attempts to authenticate them.
Username and password prompts are given (the password is obscured).
When the information is collected, it is passed to a portal and an avatar
implementing ITelnetProtocol
is requested. If an avatar is returned, it connected to this protocol's
transport, and this protocol's transport is connected to it. Otherwise, the
user is re-prompted for credentials.
| Method | __init__ | Undocumented |
| Method | connectionMade | Called when a connection is made. |
| Method | connectionLost | Called when the connection is shut down. |

Inherited from StatefulTelnetProtocol:
| Method | lineReceived | Override this for when each line is received. |
| Method | telnet_Discard | Undocumented |
Inherited from LineReceiver (via StatefulTelnetProtocol):
| Class Variable | delimiter | The line-ending delimiter to use. By default this is b'\r\n'. |
| Class Variable | MAX_LENGTH | The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384. |
| Method | clearLineBuffer | Clear buffered data. |
| Method | dataReceived | Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.) |
| Method | setLineMode | Sets the line-mode of this receiver. |
| Method | setRawMode | Sets the raw mode of this receiver. Further data received will be sent to rawDataReceived rather than lineReceived. |
| Method | rawDataReceived | Override this for when raw data is received. |
| Method | sendLine | Sends a line to the other end of the connection. |
| Method | lineLengthExceeded | Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way. |
Inherited from Protocol (via StatefulTelnetProtocol, LineReceiver):
| Method | logPrefix | Return a prefix matching the class name, to identify log messages related to this protocol instance. |
Inherited from BaseProtocol (via StatefulTelnetProtocol, LineReceiver, Protocol):
| Method | makeConnection | Make a connection to a transport and a server. |
Inherited from _PauseableMixin (via StatefulTelnetProtocol, LineReceiver):
| Method | pauseProducing | Undocumented |
| Method | resumeProducing | Undocumented |
| Method | stopProducing | Undocumented |
Inherited from TelnetProtocol (via StatefulTelnetProtocol):
| Method | unhandledCommand | A command was received but not understood. |
| Method | unhandledSubnegotiation | A subnegotiation command was received but not understood. |
| Method | enableLocal | Enable the given option locally. |
| Method | enableRemote | Indicate whether the peer should be allowed to enable this option. |
| Method | disableLocal | Disable the given option locally. |
| Method | disableRemote | Indicate that the peer has disabled this option. |
Inherited from Protocol (via StatefulTelnetProtocol, TelnetProtocol):
| Method | logPrefix | Return a prefix matching the class name, to identify log messages related to this protocol instance. |
| Method | dataReceived | Called whenever data is received. |
Inherited from BaseProtocol (via StatefulTelnetProtocol, TelnetProtocol, Protocol):
| Method | makeConnection | Make a connection to a transport and a server. |
Called when a connection is made.
This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here.
Called when the connection is shut down.
Clear any circular references here, and any external references to this Protocol. The connection has been closed.
