i have a simple client that opens a reverse port forward to a server. i've
included Jsch into my android project. it works fine for android 2.3
devices, but fails on android 2.2 and android 2.1. the error is "auth
failed". i'm using key auth as you can see below. any idea what is going
on?
here's my code,
JSch.setLogger(new AndroidLogger());
JSch jsch = new JSch();
String user = config.getUser();
Log.d("xxx", "user: " + user);
File pvtFile = new Keys(context).getPvtKeyFile();
Log.d("xxx", "using private key file: " + pvtFile);
jsch.addIdentity(pvtFile.toString());
session = jsch.getSession(user, this.reservation.getHost(), 22);
int rport = this.reservation.getPort();
String lhost = "localhost";
int lport = this.localPort;
UserInfo ui = new MyUserInfo();
session.setUserInfo(ui);
session.setServerAliveInterval(2000);
session.connect();
channel = session.openChannel("session");
channel.connect();
session.setPortForwardingR(rport, lhost, lport);
and here's the log,
