[esb-issues] [JBoss JIRA] Updated: (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 Affects Versions: 4.6 Reporter: Tom Eicher Priority: Minor Fix For: 4.7 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 org.jboss.soa.esb.util.RemoteFileSystemException: com.jcraft.jsch.JSchException: Auth fail 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: 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; }
