Oleg Zhurakousky created NIFI-1956: -------------------------------------- Summary: Add "keyboard-interactive" option to SFTPTransfer Key: NIFI-1956 URL: https://issues.apache.org/jira/browse/NIFI-1956 Project: Apache NiFi Issue Type: Improvement Affects Versions: 1.0.0, 0.7.0 Reporter: Oleg Zhurakousky Assignee: Oleg Zhurakousky
With RFC-4256 some SSH servers may no longer support or enable "password" as a valid authentication option in favor of "keyboard-interactive". This results in {code} Exception in thread "main" com.jcraft.jsch.JSchException: Auth fail {code} And even though the spec discusses the authentication mechanism where user will be prompted for a password, JSch provides an authentication provider which handles such prompt behind the scenes as long as user sets password in a session. Belo code shows how to reproduce the issue (at least in osx): {code} public static void main(String[] args) throws Exception { JSch jsch = new JSch(); Session session = jsch.getSession("<user>", "localhost", 22); session.setPassword("<password>"); Properties properties = new Properties(); properties.setProperty("StrictHostKeyChecking", "no"); //properties.setProperty("PreferredAuthentications", "publickey,password,keyboard-interactive"); properties.setProperty("PreferredAuthentications", "publickey,password"); session.setConfig(properties); session.connect(); System.out.println("connected"); } -- This message was sent by Atlassian JIRA (v6.3.4#6332)
