"com.jcraft.jsch.JSchException: Auth fail" with working passwords

Tracing the root cause, i finally found that the public key of type dsa is not added to the authorized keys on remote server. Appending the same worked for me.

The ssh was working with rsa key, causing me to look back in my code.

thanks everyone.

I have also face the Auth Fail issue, the problem with my code is that I have

channelSftp.cd("");

It changed it to

channelSftp.cd(".");

Then it works.

Try to add auth method explicitly as below, because sometimes it is required:

session.setConfig("PreferredAuthentications", "password");
