While uploading a zip file to SFTP, we are getting the below error. The same code is working fine for another application. We are using jsch-0.1.44.jar for SFTP connection. java.io.IOException: inputstream is closed at com.jcraft.jsch.ChannelSftp._put(ChannelSftp.java:571) at com.jcraft.jsch.ChannelSftp.put(ChannelSftp.java:431) at com.jcraft.jsch.ChannelSftp.put(ChannelSftp.java:398) aused by: java.io.IOException: inputstream is closed at com.jcraft.jsch.ChannelSftp.fill(ChannelSftp.java:2326) at com.jcraft.jsch.ChannelSftp.header(ChannelSftp.java:2350) at com.jcraft.jsch.ChannelSftp

I'm working on a project using R-Hadoop, and got this problem. I'm using JSch in JAVA to ssh to remote hadoop pseudo-cluster, and here are part of Java code to create connection. /* Create a connection instance */ Connection conn = new Connection(hostname); /* Now connect */ conn.connect(); /* Authenticate */ boolean isAuthenticated = conn.authenticateWithPassword(username, password); if (isAuthenticated == false) throw new IOException("Authentication failed."); /* Create a session */ Session sess = conn.openSession(); //sess.execCommand("uname -a && date && uptime && who"); sess.execCommand(

Has anyone seen where JSch leaves sshd sessions open? I've got a java client which performs regular SFTP connections (it polls every one hour) and it seems to leave behind a sshd session. These eventually build up over time and causes us to have a "too many files open" exception in the OS (it hits the limit per process(1024) for those who are interested). In my client I close the SFTPChannel, then the Channel (redundant really as closing the SFTPChannel closes the Channel) and lastly the Session, so I'm pretty sure I'm cleaning up correctly (and I can see I have a 'disconnect' for each

I am trying to use jsch to connect to a remote switch and run some command and extract the output. I am able to connect to the switch using , however the command output is not available in the inputstream. Maybe i am not doing it the right way. Here's the code session = jsch.getSession("user", "10.0.0.0", 22); session.setPassword("somepwd"); session.setConfig("StrictHostKeyChecking", "no"); session.connect(); System.out.println("connected to remote host"); Channel channel = session.openChannel("shell"); OutputStream ops = channel.getOutputStream(); PrintStream ps = new PrintStream(ops);
