APAR status

  • Closed as program error.

Error description

  • Some SFTP servers can obfuscate file permissions for security
    reasons.  If this occurs, an error can occur which prevents IIB
    from reading the file.  The error is seen in a service trace:
    RemoteService.parseUnixString 'Error parsing unix string from
    remote SFTP server'
    The permissions are read as part of IIB filtering the files
    based on the file name pattern property and sorting by oldest
    first.
    

Local fix

  • Disable obfuscated permissions on the SFT server
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of IBM Integration Bus version 10 or App Connect
    Enterprise version 11 using the FileInput or FileRead Nodes to
    connect to a remote SFTP server.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    <span style="background-color:rgb(255, 255, 255)">Some SFTP
    servers can obfuscate file permissions for security reasons. If
    this occurs, an error can occur which prevents the File Node
    from parsing the directory listing returned by the remote SFTP
    server. This prevents the transmission of any files in this
    directory.
    
    The following error is seen in a service trace:
    
    RemoveService.parseUnixString 'Error parsing unix string from
    remote SFTP server'</span>
    

Problem conclusion

  • The File Nodes will now correctly parse a directory listing
    containing obfusticated file access permissions.
