Hi,
I have used JSCH library to use SFTP as a batch process. Hence I am not
using the interactive keyboard "userinfo" that was available as part of the
example, but I am getting the userinfo populated from UI available in my
application.
I have used the following piece of code:
JSch jsch=new JSch();
String userName=userInfo.getUserName();
String hostName=userInfo.getHostName();
int port=22;
session=jsch.getSession(userName, hostName, port);
String password=userInfo.getPassword();
session.setPassword(password.getBytes());
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
The code worked perfectly for many of the servers. But it was showing an
error "Auth Cancel" for a specific server. So after reading the article
above I added the following line of code:
session.setConfig("PreferredAuthentications","password");
Now the error coming is "Auth fail". Please let me know how to proceed. I
would also like to add that the specific server that was failing had PAM
authentication(not sure if this is the reason that its failing).
