[JSch-users] port 22 forwarding

[Jean-Philippe P. <jp...@gm...>]

Hello,

I am trying to  to forward the port 22 of host B to the port 51501 on host
A. I got no error but if I try to connect to host A on port 51501 I get a
connection refused :

 ssh -p 51501
ssh: connect to host prod port 51501: Connection refused


here is my code

String host="A";
        String user="user";;
        int port=22;

        int tunnelLocalPort=51501;
        String tunnelRemoteHost="B";
        int tunnelRemotePort=22;

        JSch jsch=new JSch();
        session=jsch.getSession(user, host, port);
        MyUser lui=new MyUser();
        session.setUserInfo(lui);
        session.connect();

//session.setPortForwardingL(tunnelLocalPort,tunnelRemoteHost,tunnelRemotePort);

session.setPortForwardingL("0.0.0.0",tunnelLocalPort,tunnelRemoteHost,tunnelRemotePort);
        System.out.println("Connected");



If I try to set up manualy :

I connect to host A and then execute :

ssh -Ng -L 50123:localhost:22 user@B


then if I try to connect to host A on port 50123 it works

running netstats on host A :

netstat -an | grep 50123
tcp        0      0 0.0.0.0:50123           0.0.0.0:*               LISTEN


When using jsch I have no error/ exception, but if I run "netstat -an | grep
51501 " it is empty...


What am I doing wrong ? The example look simple but I can't achieve to make
it works....


Thanks for help !
