Examples of ServerSessionCallback

ch.ethz.ssh2.ServerSessionCallback
The interface for an object that receives events based on requests that a client sends on a session channel. Once the session channel has been set up, a program is started at the server end. The program can be a shell, an application program, or a subsystem with a host-independent name. Only one of these requests can succeed per channel.
CAUTION: These event methods are being called from the receiver thread. The receiving of messages will be blocked until your event handler returns. To signal to the client that you are willing to accept its request, return a {@link Runnable} object which will be executedin a new thread after the acknowledgment has been sent back to the client.
If a method does not allow you to return a {@link Runnable}, then the SSH protocol does not allow to send a status back to the client (more exactly, the client cannot request an acknowledgment). In these cases, if you need to invoke methods on the {@link ServerSession} or plan to execute long-running activity, then please do this from within a new {@link Thread}.
If you want to signal a fatal error, then please throw an IOException. Currently, this will tear down the whole SSH connection. @see ServerSession @author Christian
