Specified by:

attach in interface SSH2TerminalAdapter

Parameters:

session - The session to attach to.

detach

public void detach()

Description copied from interface: SSH2TerminalAdapter

Detach from the session

Specified by:

detach in interface SSH2TerminalAdapter

startChaff

public void startChaff()

Description copied from class: TerminalInputChaff

Start sending chaff

Specified by:

startChaff in interface SSH2TerminalAdapter

Overrides:

startChaff in class TerminalInputChaff

Overrides:

stopChaff in class TerminalInputChaff

closed

public void closed(SSH2Channel channel)

Description copied from interface: SSH2ChannelCloseListener

Called when the channel is closed.

Specified by:

Specified by:

sendTypedChar in class TerminalInputChaff

Parameters:

c - The typed character to send.

sendFakeChar

protected void sendFakeChar()

Send a fake character. Sends a packet which is the same size as a real keypress packet but it contains no data.

Specified by:

sendFakeChar in class TerminalInputChaff

sendBytes

public void sendBytes(byte[] b)

Send a number of bytes.

Specified by:

sendBytes in interface TerminalInputListener

Parameters:

b - Array of bytes to send.

sendBytesDirect

public void sendBytesDirect(byte[] b)

Description copied from interface: TerminalInputListener

Send some bytes directly to the host. This does not echo the characters and bypasses any line buffering. This is typically used when replying to some query from the host.

Specified by:

sendBytesDirect in interface TerminalInputListener

Parameters:

b - array of bytes representing characters to send

signalWindowChanged

public void signalWindowChanged(int rows,
                       int cols,
                       int vpixels,
                       int hpixels)

This function should be called by the actual terminal window whenever it is resized.

Specified by:

signalWindowChanged in interface TerminalInputListener

Parameters:

rows - new number of rows

cols - new number of columns

vpixels - new number of vertical pixels

hpixels - new number of horizontal pixels

sendBreak

public void sendBreak()

This function should be called by the actual terminal window whenever the user wants to send break. A break length of 500ms is used, since most devices will recognize a break of that length.

Specified by:

sendBreak in interface TerminalInputListener

Overrides:

sendBreak in class TerminalInputChaff
