Hi Guillaume,
There is no such thing... I will surely use the mailing lists for further
communications.
Long time back I asked for the help regarding the implementation of
sftpclient using apache sshd library...
My plan is to execute sftp commands in sftp subsystem mode.
In my entry class, I have added chunk of code shown below:
ClientChannel channel =
session.createSubsystemChannel( "sftp" );
InputStream in = new ByteArrayInputStream(
"ls".getBytes() );
channel.setIn(in);
channel.setOut(System.out);
channel.setErr(System.err);
channel.open().await();
And in ChannelSubsystem.java class, below api is provided:
protected void doOpen() throws Exception {
super.doOpen();
log.info("Send SSH_MSG_CHANNEL_REQUEST subsystem...");
Buffer buffer =
session.createBuffer(SshConstants.Message.SSH_MSG_CHANNEL_REQUEST, 0);
buffer.putInt(recipient);
buffer.putString("subsystem");
buffer.putBoolean(true);
buffer.putString(subsystem);
session.writePacket(buffer);
}
After executing the entry class I got following logs:
2012-04-12 18:25:14,106 [main ] INFO ChannelSubsystem
- Send SSH_MSG_CHANNEL_OPEN on channel 0
2012-04-12 18:25:18,202 [NioProcessor-2 ] INFO ClientSessionImpl
- Received SSH_MSG_CHANNEL_OPEN_CONFIRMATION on channel 0
2012-04-12 18:25:18,204 [NioProcessor-2 ] INFO ChannelSubsystem
- Send SSH_MSG_CHANNEL_REQUEST subsystem...
2012-04-12 18:25:18,227 [NioProcessor-2 ] INFO ClientSessionImpl
- Closing session
2012-04-12 18:25:18,230 [NioProcessor-2 ] INFO ChannelSubsystem
- Closing channel 0 immediately
My question here is, why is it closing the session after sending
SSH_MSG_CHANNEL_REQUEST for subsystem?
