> SSH server doesn't know when auth completed

> Key: SSHD-203
> URL: https://issues.apache.org/jira/browse/SSHD-203
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 0.8.0
> Environment: Windows
> Reporter: Andrew C
> Assignee: Guillaume Nodet

> To the best of my knowledge, there's no way, in a customised SSH server, to
> detect when the client connection's auth has successfully completed. As a
> hack I came up with:
> public class RelaySshSession extends ServerSession {
> private final RelayService relayService;
> public RelaySshSession(RelayService relayService, SshServer server,
> IoSession sshIoSession) throws Exception {
> super(server, sshIoSession);
> this.relayService = relayService;
> }
> @Override
> public CloseFuture close(boolean immediately) {
> relayService.unbind(this);
> return super.close(immediately);
> }
> private boolean authorized = false;
> @Override
> public WriteFuture writePacket(Buffer buffer) throws IOException {
> if (!this.authorized) {
> byte[] bytes = buffer.array();
> if (bytes.length > 5 && bytes[5] ==
> SshConstants.Message.SSH_MSG_USERAUTH_SUCCESS.toByte()) {
> // need to send the auth packet before starting network
> session so that the
> // local service packets always follow the service.
> WriteFuture writeFuture = super.writePacket(buffer);
> // Tell the server side to start.
> relayService.bind(this);
> this.authorized = true;
> return writeFuture;
> }
> }
> return super.writePacket(buffer);
> }
> }
> As an example for why this might be useful, consider a dispatcher that
> accepts multiple clients. As long as any client is active the custom server
> send dispatch messages.
