Simple SSH Tunnel in Java

问题

I want to create an SSH Tunnel in Java. I noticed quite a few Java SSH libraries on another post. Before I dig into each option, maybe someone can give me some code snippets of how they did it or at least tell me which client library would work best.

I only need tunneling. I won't need stuff like file transfers, terminal emulation, etc. Is there a simple few lines of code that can forward a port on the server to work on my client's localhost adapter? Ideally both client and server would be in Java, but I'll settle for just client for now.

回答1:

Well, as pointed out in the other question, JSch is indeed a great choice and has several examples here. The PortForwardingL.java class might be a good starting point.

You can do this with several libraries. My favorite is the ssh library inside MindTerm package,

You can open a tunneled connection like this,

  SSHSocketFactory fact = new SSHSocketFactory(sshHost, sshPort, new SSHPasswordAuthenticator(sshUser, sshPassword));

  sock = fact.createSocket(host, port);
