RE: [JSch-users] session unexpectedly closed

[Liu, X. <xia...@le...>]

Hi,

Yes, scpTo sample does work for me. But in my code, i reuse the
same opening session to issue other commands like 'mkdir' 'ln -s' etc
besides copying.

The exceptions are:

SSH_MSG_DISCONNECT: 2 Received ieof for nonexistent channel 0.=20
Caused by: com.jcraft.jsch.JSchException: session is down
	at com.jcraft.jsch.Channel.connect(Unknown Source)
	at
com.lehman.etrading.management.tool.JSSHRemoteShell.exec(JSSHRemoteShell
..java:144)
	at
com.lehman.etrading.management.deployment.ServiceDeployer.doRelease(Serv
iceDeployer.java:347)
	... 8 more

It always fails on the line 'channel.connect()'. Is their 'debug' mode
or logging that
i can turn on to produce more debug information=3F My current workaround
is break down
a list of commands i need to do in separate sessions which probably is
not a good idea.

channel =3D (ChannelExec)session.openChannel("exec");
            channel.setCommand(cmd);
            channel.setXForwarding(true);
            channel.setInputStream(in);
            channel.setOutputStream(out);
            channel.setErrStream(err);
            channel.connect();
            while (!channel.isEOF());

Regards,

XLiu.

   |Hi, all, Hope you can help me with this. I created a session to do
   |multiple things like the following
   ...
   |Some are for copying files
   |            channel          =3D
(ChannelExec)session.openChannel("exec");
   |            OutputStream out =3D channel.getOutputStream();
   |            InputStream in   =3D channel.getInputStream();
   |
   |            //exec 'scp -t file' remotely
   |            String command   =3D "scp -t " + remoteFileName;
   |            ((ChannelExec)channel).setCommand(command);
   |            channel.connect();
   |
   |For some reason, the sessions are unexpectedly closed and throws
   |exception like:
   |SSH_MSG_DISCONNECT: 2 Received ieof for nonexistent channel 0.

I'm sorry, but there are not enough hints to guess what has happend.
Will jsch-0.1.16/examples/ScpTo.java work on your environment=3F

Thanks,

ymnk
