Tóm lược:
Rõ ràng tôi không thể kết nối với VPN với Cisco IPSec vì Bí mật chung không được lưu sau khi nhập (nó luôn trống).
Giải thích chi tiết:
Tôi đã tạo kết nối VPN với Cisco IPSec và kết nối thành công. Đột nhiên (một vài giờ sau) tôi bị ngắt kết nối và gặp lỗi sau khi cố gắng kết nối lại:
"Máy chủ VPN không phản hồi. Xác minh địa chỉ máy chủ và thử kết nối lại."
Địa chỉ là ok, vì vậy tôi đã kiểm tra các bản ghi và tìm thấy:
Feb 22 17:59:35 gerry racoon[4401]: couldn't find the pskey by address 204.232.144.166.
Tôi đã kiểm tra bí mật được chia sẻ và nó trống; Tôi gõ nó một lần nữa, nhấp vào ok và mở nó ngay lập tức và nhận lại một bí mật được chia sẻ trống. Tôi đã gõ bí mật được chia sẻ một lần nữa và cố gắng kết nối và nhận được các bản ghi sau:

Tôi đã tìm kiếm thông tin liên quan đến nhật ký này nhưng không thể biết liệu chúng có liên quan đến vấn đề này không.
Tôi đã thử xóa kết nối VPN và tạo một kết nối mới (nhân tiện, tôi không thể sử dụng cùng tên) và nó cũng không hoạt động, vì vậy, một lần nữa, tôi xem lại nhật ký:
Feb 22 18:16:26 gerry nesessionmanager[951]: Failed to load configuration with ID <__NSConcreteUUID 0x7fedfa504910> A7892601-20D6-4D80-88B7-8D2AA22CF4E1

Thật không may, tôi không thể tạo bất cứ thứ gì mà không có các bản ghi đó (cùng một bản ghi lặp lại khoảng 20 lần và dừng lại), vì vậy tôi đã xóa tất cả các kết nối VPN của mình (một lần nữa), tạo một bản ghi mới (lần này tôi có thể chọn cùng một tên ) và có một mục nhật ký khác nhau:
Feb 22 18:31:49 gerry nehelper[217]: 3C44D371-6954-4001-A2D7-0100446EDA8A.XAUTH: SecKeychainItemCreateFromContent failed: User interaction is not allowed.

Cuối cùng tôi đã tìm kiếm mục nhập móc khóa (trong truy cập móc khóa) cho kết nối VPN của tôi nhưng không tìm thấy. Tôi đoán đây có thể là vấn đề.
Bất kỳ ý tưởng những gì có thể là vấn đề? Tôi đã cố gắng kết nối trong một máy Mac khác (cùng hệ điều hành, El Capitan) và không gặp vấn đề gì, nhưng không thể khiến VPN hoạt động trên máy Mac của tôi.
Cảm ơn bạn!
