Constructor Detail

ServerSession

public ServerSession(FactoryManager server,
                     org.apache.mina.core.session.IoSession ioSession)
              throws java.lang.Exception

Throws:

java.lang.Exception

Method Detail

close

public CloseFuture close(boolean immediately)

Description copied from class: AbstractSession

Close this session. This method will close all channels, then close the underlying MINA session. The call will not block until the mina session is actually closed.

Overrides:

close in class AbstractSession

getNegociated

public java.lang.String getNegociated(int index)

getKex

public KeyExchange getKex()

getSessionId

public byte[] getSessionId()

getServerFactoryManager

public ServerFactoryManager getServerFactoryManager()

getScheduledExecutorService

protected java.util.concurrent.ScheduledExecutorService getScheduledExecutorService()

handleMessage

protected void handleMessage(Buffer buffer)
                      throws java.lang.Exception

Description copied from class: AbstractSession

Abstract method for processing incoming decoded packets. The given buffer will hold the decoded packet, starting from the command byte at the read position. Packets must be processed within this call or be copied because the given buffer is meant to be changed and updated when this method returns.

Specified by:

handleMessage in class AbstractSession

Parameters:

buffer - the buffer containing the packet

Throws:

java.lang.Exception - if an exeption occurs while handling this packet.

readIdentification

protected boolean readIdentification(Buffer buffer)
                              throws java.io.IOException

Description copied from class: AbstractSession

Read the other side identification. This method is specific to the client or server side, but both should call AbstractSession.doReadIdentification(org.apache.sshd.common.util.Buffer) and store the result in the needed property.

Specified by:

readIdentification in class AbstractSession

Parameters:

buffer - the buffer containing the remote identification

Returns:

true if the identification has been fully read or false if more data is needed

Throws:

java.io.IOException - if an error occurs such as a bad protocol version

getHostKey

public java.security.KeyPair getHostKey()

getActiveSessionCountForUser

protected int getActiveSessionCountForUser(java.lang.String userName)

Retrieve the current number of sessions active for a given username.

Parameters:

userName - The name of the user

Returns:

The current number of live SshSession objects associated with the user

initAgentForward

public java.lang.String initAgentForward()
                                  throws java.io.IOException

Throws:

java.io.IOException

createX11Display

public java.lang.String createX11Display(boolean singleConnection,
                                         java.lang.String authenticationProtocol,
                                         java.lang.String authenticationCookie,
                                         int screen)
                                  throws java.io.IOException

Throws:

java.io.IOException
