[esb-issues] [JBoss JIRA] Created: (JBESB-2875) Support sftp (ssh) keyboard-interactive auth
Support sftp (ssh) keyboard-interactive auth
--------------------------------------------
Key: JBESB-2875
URL: https://jira.jboss.org/jira/browse/JBESB-2875
Project: JBoss ESB
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: Adapters
Reporter: Tom Eicher
Priority: Minor
JSch, as it is currently used in SecureFtpOverSSH, does only allow "password"
authentication.
However, this requires that the target system has ssh configured for
"PasswordAuthentication yes" in sshd_conf, which is by default "no"
nowadays...
Connections will fail with
{code}
org.jboss.soa.esb.util.RemoteFileSystemException: com.jcraft.jsch.JSchException: Auth
fail
{code}
To allow connections to servers configured like this, we need to support
"keyboard-interactive" additionally:
1. SecureFtpImpl:
change session.setConfig("PreferredAuthentications", "password");
to session.setConfig("PreferredAuthentications",
"password,keyboard-interactive");
2. SecureFtpUserInfo:
additionally implement JSch interface UIKeyboardInteractive:
{code}
public String[] promptKeyboardInteractive(
String destination,
String name,
String instruction,
String[] prompt,
boolean[] echo){
if(prompt.length!=1 || echo[0]!=false || this.password==null){
return null;
}
String[] response=new String[1];
response[0]=this.password;
return response;
}
{code}
