Re: [JSch-users] How to use JSch for the following scenario

[B. S. S. <sc...@sm...>]

Yes.

    JSch jsch = *new* JSch();
    Session session1 = jsch.getSession(username, "firewall", 22);
    session1.setUserInfo(*new* MyUserInfo(password1));
    session1.connect();
    session1.setPortForwardingL(8822, "machine", 22);
    Session session2 = jsch.getSession(username, "localhost", 8822);
    session2.setUserInfo(*new* MyUserInfo(password2));
    session2.connect();
    // Now execute all commands by creating channel on session2
