    Domain Name System Security Extensions – DNSSEC

    Dear users,

    Regardins DNSSEC: https://en.wikipedia.org/wiki/Domain_Name_System_Security_Extensions

    Since version 2018.11.2.0 we’ve added a DNS option tab to the SFTP Source and Destination Setup. This option let’s you override the system DNS. Reason that we’ve added this is security (suppose your system got hacked). This option let’s you firmly control the DNS requests. We’ve also added an option to use DNSSEC (“Use Security”). This is all new for us so feedback is more than welcome.

    SSL Error Codes


    Copyright www.secureblackbox.com Value Possible reason and steps to take
    ERROR_SSL_TIMEOUT 73730 (0x12002)
    1. Connection is made to/from a service that doesn’t talk proper SSL (e.g. a plain HTTP connection is made to an HTTPS port). Re-check that both client and server services are talking SSL.
    2. Unsupported version of the protocol. Try to play with Versions property of the SSL component and check if any of the combination helps.
    ERROR_SSL_BAD_RECORD_MAC 75778 (0x12802) The peers failed to negotiate a shared key material. Try connecting with different cipher suites one-by-one and check if any of them helps. If neither does, try to use a different protocol version.
    ERROR_SSL_DECODE_ERROR 75792 (0x12810)
    ERROR_SSL_DECRYPT_ERROR 75793 (0x12811)
    ERROR_SSL_RECORD_OVERFLOW 75780 (0x12804) Packet size too large. Try to decrease the maximal size of the packet by adjusting the MaxFragmentLength extension.
    ERROR_SSL_DECOMPRESSION_FAILURE 75781 (0x12805) Compression or decompression failure. Switch off compression (CompressionAlgorithms property).
    ERROR_SSL_HANDSHAKE_FAILURE 75782 (0x12806) Incompatible versions or cipher suite lists. Try to play with version and cipher suite sets. Check that the server certificate is provided and has an associated private key.
    ERROR_SSL_NO_CERTIFICATE 75783 (0x12807) The certificate provided by the peer is not valid.
    ERROR_SSL_BAD_CERTIFICATE 75784 (0x12808)
    ERROR_SSL_UNKNOWN_CA 75790 (0x1280E)
    ERROR_SSL_ACCESS_DENIED 75791 (0x1280F) The requested application-layer resource cannot be accessed by the requestor. Check with the administrator of the remote resource.
    ERROR_SSL_EXPORT_RESTRICTION 75794 (0x12812) The peer is only configured to use exportable cipher suites. Switch on support for “EXPORT” cipher suites.
    ERROR_SSL_PROTOCOL_VERSION 75795 (0x12813) The peers have not been able to negotiate a version to use (no shared protocol versions).
    ERROR_SSL_INSUFFICIENT_SECURITY 75796 (0x12814) The cipher suites mutually supported by the peers are too weak and do not provide an adequate level of security.
    ERROR_SSL_INTERNAL_ERROR 75797 (0x12815) Contact the vendor.
    ERROR_SSL_USER_CANCELED 75798 (0x12816) Application layer has shut down the connection.
    ERROR_SSL_NO_RENEGOTIATION 75799 (0x12817) One of the peers requested a renegotiation, which was refused by the other. Note that you will get this error (as a warning) if you return Allow = false from the OnRenegotiationStart event handler.
    ERROR_SSL_CLOSE_NOTIFY 75800 (0x12818) Does not indicate an error condition. The SSL connection was closed gracefully and can be restored or cloned in future.

    FTP Error Codes


    Copyright www.secureblackbox.com Value Description
    SB_FTPS_ERROR_CONTROL_CHANNEL_HANGUP 114689 (0x1C001) Some servers hang up control channels if no information is sent or received within rather short time. Hence, on large file transfers, the code which reports successful operation completion (226/250) is not sent by the server. FTPS client returns SB_FTPS_ERROR_CONTROL_CHANNEL_HANGUP error code when the command channel hangs up, but when the session was gracefully closed by the server (i.e., file transfer was finished successfully).
    SB_FTPS_ERROR_CONTROL_CHANNEL_NO_DATA 114690 (0x1C002) No data is being transferred via control channel.
    SB_FTPS_ERROR_UNACCEPTED_REPLY_CODE 115713 (0x1C401) Unaccepted reply code. Such codes may be sent by servers when data connection closure was initiated on the client side.
    SB_FTPS_ERROR_INVALID_REPLY 115714 (0x1C402) Invalid reply.
    SB_FTPS_ERROR_LOCAL_SOURCE_NOT_FILE 116737 (0x1C801) Local source is not a file.
    SB_FTPS_ERROR_LOCAL_TARGET_NOT_FILE 116738 (0x1C802) Local target is not a file.
    SB_FTPS_ERROR_RESUME_OFFSET_TOO_LARGE 116739 (0x1C803) This error is fired when the it is impossible to resume data transfer (because resume offset is too large).
    SB_FTPS_ERROR_OPERATION_CRITERIA_NOT_MET 116740 (0x1C804) The criteria for the requested operation is not met.
    SB_FTPS_ERROR_TIMES_NOT_SET 116741 (0x1C805) The criteria for the requested operation is not met.
