Di mana kunci tautan bluetooth disimpan di Ubuntu 14.10?

Saya mencoba untuk mengatur kunci tautan bluetooth khusus untuk perangkat di Ubuntu 14.10 tetapi saya tidak dapat menemukan di mana mereka disimpan.
Tujuannya adalah agar mouse bluetooth berfungsi di Ubuntu dan Windows tanpa harus memasangkannya kembali setelah berpindah sistem operasi.
Semua jawaban yang saya temukan di AskUbuntu menyatakan bahwa kunci disimpan /var/lib/bluetooth/<mac_address>/linkkeysdan ini digunakan setidaknya sampai pukul 13.10, tetapi pada 14.10 file ini hilang dari instalasi desktop yang bersih dan membuatnya secara manual tidak memiliki efek, diabaikan oleh bluetoothd.

EDIT: Tampaknya mouse tidak mengeluarkan permintaan pemasangan dan kunci tautan tidak disimpan dalam kasus ini. Namun, menghubungkan mouse di Windows dan kemudian reboot di Ubuntu menyebabkan koneksi bluetooth gagal (dan mouse perlu dihapus dan ditambahkan kembali ke daftar perangkat bluetooth), jadi pasti ada beberapa pertukaran kunci / otentikasi yang terjadi yang mencegah mouse agar tidak dibagikan di kedua OS. Pertanyaannya tetap, bagaimana saya bisa memaksa bluetoothd untuk menyimpan dan menggunakan tombol tautan yang disimpan saat menghubungkan mouse ini?

Detail perangkat keras:

• Microsoft Bluetooth Notebook Mouse 5000
• 413c: 8161 Dell Computer Corp. Wireless 365 Bluetooth (Broadcom BCM2046B1)

Dua log di bawah ini menunjukkan bahwa untuk perangkat yang dapat dipasangkan (ponsel) kunci disimpan dalam file tautan; ini bukan kasus untuk mouse. Saya tahu bahwa versi bluetoothd yang lebih lama digunakan untuk menyimpan kunci tautan untuk tikus juga, karena ada banyak jawaban / tutorial di sini tentang askubuntu dan ubuntuforums tentang menyalin tautan kunci dari Windows ke Ubuntu untuk tujuan khusus berbagi mouse antara dua OS.

Berikut ini adalah log bluetoothd untuk penemuan mouse dan pengaturan koneksi:

Setelah beberapa saat, saya akhirnya menyelesaikan masalah yang saya hadapi. Saya masih belum menemukan jawaban untuk pertanyaan awal (saya tidak bisa menentukan di mana tombol tautan disimpan untuk kombinasi bluez / adaptor / periferal khusus ini) tetapi saya mengetahui bahwa bluez akan membaca file tautan, jika ada, dan akan menggunakan kunci dalam file.

Jadi, meskipun kunci tautan mungkin tidak ditulis ke file setelah dipasangkan, dimungkinkan untuk mengganti kunci-kunci itu dengan menambahkannya secara manual ke file tautan kunci.

Penting bahwa jenis kunci diatur dengan benar, jika tidak maka kunci tersebut akan diabaikan.

Untuk referensi, jenis kunci yang berfungsi dalam kasus saya ditampilkan di sini: /ubuntu//a/246791/352576

Ubuntu 13.10 menggunakan bluez 4.98, 14.04 dan 14.10 menggunakan 4.101

Kedua versi dikompilasi dengan opsi yang sama (--localstatedir = / var)

Saya menggunakan 14,04 dan file ada di sana dan jika saya menghapus atau menambahkan perangkat file / var / lib / bluetooth / (myadapteraddress) / linkkeys diperbarui sesuai.

Saya membuat tes pada sistem 14.10, saya menambahkan perangkat BT dan file / var / lib / bluetooth / (adapteraddress) / linkkeys dibuat

Mungkin Anda menggunakan versi bluez yang lebih baru.

Skema untuk versi baru bluez (5 dan seterusnya saya pikir):

/var/lib/bluetooth/<adapter address>/<remote device address>/info

Dalam dokumentasi penyimpanan pengaturan untuk versi bluez baru, saya menemukan ini:

http://git.kernel.org/cgit/bluetooth/bluez.git/tree/doc/settings-storage.txt

...

Storage directory structure

There is one directory per adapter, named by its Bluetooth address, which
contains:
 - a settings file for the local adapter
 - an attributes file containing attributes of supported LE services
 - a cache directory containing:
    - one file per device, named by remote device address, which contains device name
 - one directory per remote device, named by remote device address, which contains:
    - an info file
- an attributes file containing attributes of remote LE services
- a ccc file containing persistent Client Characteristic Configuration
  (CCC) descriptor information for GATT characteristics

So the directory structure is:

/var/lib/bluetooth/<adapter address>/

    ./settings
    ./attributes
    ./cache/
        ./<remote device address>
        ./<remote device address>
        ...
    ./<remote device address>/
        ./info
        ./attributes
        ./ccc
    ./<remote device address>/
        ./info
        ./attributes
    ...

...

Info file format

...

[LinkKey] group contains:

  Key           String      Key in hexadecimal format

  Type          Integer     Type of link key

  PINLength     Integer     Length of PIN

...

Bagaimanapun bluez harus menyimpan file di / var / lib / bluetooth

Jika Anda menggunakan perintah ini

bluetoothd --version

Anda mendapatkan 4,101?

/ var / lib / bluetooth / {bluetoothaddr} / tautankunci

Di mana {bluetoothaddr} adalah antarmuka bluetooth Anda (Anda seharusnya hanya memiliki satu, itu terlihat seperti alamat mac)

Format file adalah {remoteaddr} {128 bit key key} {type}.

20:12:03:22:EE:0E C21D3A69DEA0A8C629F1BB5D12AEEA79 4 0
00:18:94:68:3E:90 EC02519ED656DB87B7F152E899F8A810 0 4
00:21:3F:3E:2E:6C 948A0EF91FA8E9EB9032CE775BF8E0B0 0 4

Di Debian Jessie & saya menganggap Ubuntu juga Anda dapat secara manual mengatur PIN untuk digunakan.

1. Lakukan apa yang dijelaskan oleh pos ini /ubuntu//a/246791/352576 untuk mendapatkan kunci windows Anda.
2. Anda /var/lib/bluetooth/XX:XX:XX:XX:XX:AA(di mana XX: ... :AAmac dari adaptor BT PC Anda) harus berisi direktori dengan mac dari mouse / keyboard BT Anda (saya akan menyatakannya sebagai XX: ... :BF, dan file config, & pengaturan.

3. di dalamnya XX: ... BFada file yang infodimiliki oleh root, dengan izin rw untuk root. Tidak ada izin lain .-- konten harus:

   [LinkKey] 
   Key=A7XXXXXXXXXXXXXXXXXXXXXXXXXXXX89 
   Type=4
   PINLength=0
   
   [General]
   Name=yourMouseName
   Class=0x002580
   SupportedTechnologies=BR/EDR;
   Trusted=true
   Blocked=false
   Services=00001000-0000-1000-8000-00805f9b34fb;00001124-0000-1000-8000-00805f9b34fb;00001200-0000-1000-8000-00805f9b34fb;
   
   [DeviceID]
   Source=2
   Vendor=1133
   Product=45069
   Version=1792
   

   Perhatikan panjang kuncinya adalah 16 byte.

menempelkan file tautan di direktori ini tidak membantu saya - meskipun saya membiarkannya dalam ukuran yang baik.
