Amin's Note

小弟的NB灌Linux好歹也一年多了，只是都很懶的去搞指紋辨識，所以拖到現在才處理 :p

環境： Ubuntu Lucid (10.04) x86
硬體：HP dv2756tx (dv2000) 
         AuthenTec, Inc. AES2501 Fingerprint Sensor

1.檢查是否是 AES2501

$ lsusb

將會看到類似的東西

AuthenTec, Inc. AES2501 Fingerprint Sensor

如果沒有出現，就請不要繼續下去了 :P

2.安裝所需的套件

$sudo apt-get install aes2501-wy

$sudo apt-get install libfprint0 libpam-fprint fprint-demo

3.測試指紋辨識是否正常

$sudo aes2501 -r

將會看到類似的畫面
argc=1 Initializing, please standby...
aesSetup()...
aesStartScan()...
READY (touch the sensor to stop)
Scanning...
Assembling...

以及一個指紋圖片

如果以上正常，那就恭喜你，你的指紋辨識成功安裝了！

接下來就是將sudo/su 結合指紋辨識功能

4.紀錄指紋到系統中

#pam_fprint_enroll --enroll-finger 7

正常應該是會出現類似以下的訊息

This program will enroll your finger, unconditionally overwriting any selected print that was enrolled previously. If you want to continue, press enter, otherwise hit Ctrl+C

Found device claimed by AuthenTec AES2501 driver
Opened device. It's now time to enroll your finger.

You will need to successfully scan your Right Index Finger 1 times to complete the process.

Scan your finger now.
Enroll complete!
Enrollment completed!

完成動作後，指紋紀錄就完成了

接著要將指紋辨識加入登入驗證中

5.加入指紋驗證到pam驗證中

#sudo vi /etc/pam.d/common-auth

將

auth sufficient pam_fprint.so

放在

auth    [success=2 default=ignore]  pam_unix.so nullok_secure

之前

接著存檔離開

6.測試是否加入驗證成功

開啟一個新的終端機，並執行

$sudo -s

是否會出現

Scan right index finger on AuthenTec AES2501

如果出現以後，請刷下您的指紋，如果正常登入，那應該是一切正常。
