--------------------------------------
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");
}
