Method Details

addWindowBytes(self, bytes)

Called when bytes are added to the remote window. By default it clears the data buffers.

Parameters:: bytes
(type=int)

channelOpen(self, specificData)

Called when the channel is opened. specificData is any data that the other side sent us when opening the channel.

Parameters:: specificData
(type=str)

closed(self)

Called when the channel is closed.

dataReceived(self, data)

Called when we receive data.

Parameters:: data
(type=str)

eofReceived(self)

Called when the other side will send no more data.

extReceived(self, dataType, data)

Called when we receive extended data (usually standard error).

Parameters:: dataType
(type=int); data
(type=str)

getHost(self)

Return a tuple describing our side of the connection.

Returns:: tuple

getPeer(self)

Return a tuple describing the other side of the connection.

Returns:: tuple

loseConnection(self)

Close the channel.

openFailed(self, reason)

Called when the the open failed for some reason. reason.desc is a string descrption, reason.code the the SSH error code.

Parameters:: reason
(type=error.ConchError)

requestReceived(self, requestType, data)

Called when a request is sent to this channel. By default it delegates to self.request_<requestType>. If this functio returns true, the request succeeded, otherwise it failed.

Parameters:: requestType
(type=str); data
(type=str)

Returns:: bool

startWriting(self)

Called when the remote buffer has more room, as a hint to continue writing.

stopWriting(self)

Called when the remote buffer is full, as a hint to stop writing. This can be ignored, but it can be helpful.

write(self, data)

Write some data to the channel. If there is not enough remote window available, buffer until it is.

Parameters:: data
(type=str)

writeExtended(self, dataType, data)

Send extended data to this channel. If there is not enough remote window available, buffer until there is.

Parameters:: dataType
(type=int); data
(type=str)

writeSequence(self, data)

Part of the Transport interface. Write a list of strings to the channel.

Parameters:: data
(type=list of str)
