An overview about the differences and similarities between these streams you can find at »Shell, Exec or Subsystem Channel« in the JSch wiki. Here some details for your use case. In the exec channel, the commands come from the command string you did give with setCommand(). The SSH server will pass them at once to … Read more
Tracing the root cause, i finally found that the public key of type dsa is not added to the authorized keys on remote server. Appending the same worked for me. The ssh was working with rsa key, causing me to look back in my code. thanks everyone.
I managed to make it work (tried to forward port to “localhost” rather than “127.0.0.1”, changing it fixed it) edit: I guess the server was listening specifically on localhost rather than 127.0.0.1
Have a look at Runtime.exec() Javadoc Process p = Runtime.getRuntime().exec(“ssh myhost”); PrintStream out = new PrintStream(p.getOutputStream()); BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream())); out.println(“ls -l /home/me”); while (in.ready()) { String s = in.readLine(); System.out.println(s); } out.println(“exit”); p.waitFor();
jsch 0.1.50 has been released and it fixes this problem. The download page for jsch is http://www.jcraft.com/jsch/

I just needed to add session.setConfig(“PreferredAuthentications”, “publickey,keyboard-interactive,password”); before session.connect(); and everything works perfectly now.
My understanding is that you want to access a mysql server running on a remote machine and listening on let’s say port 3306 through a SSH tunnel. To create such a tunnel from port 1234 on your local machine to port 3306 on a remote machine using the command line ssh client, you would type … Read more
