Ubuntut43 Fingerprint device installation

1. Download Software first go to the http://thinkfinger.sourceforge.net download tf-tool3.0file name thinkfinger-0.3.tar.gz 2. Install the gcc compiling environment sudoapt-getinstalllibtoolpkg-configlibpam0g-devlibusb-devbuild-essential3. Unzip the package tar-xz

1. Download Software

Go to http://thinkfinger.sourceforge.net to download tf-tool 3.0

File Name thinkfinger-0.3.tar.gz

2. Install the gcc compiling environment

Sudo apt-get install libtool pkg-config libpam0g-dev libusb-dev build-essential

3. decompress the Software Package

Tar-xzvf thinkfinger-0.3.tar.gz

4. Go to the working directory

Cd thinkfinger-0.3

5. Run

./Configure -- with-securedir =/lib/security -- with-birdir =/etc/pam_thinkfinger

Because the default prefix is/usr/local, if this parameter is not added, the fingerprint data will be stored in/usr/local/etc/pam_thinkfinger, while

Thinkfinger needs to put the user fingerprint data under/etc/pam_thinkfinger

6. Compile and install

Make

Sudo make install

7. Common commands

Sudo tf-tool -- acquire

Test whether fingerprint data is obtained normally.

The following error may occur:

Tf-tool: error while loading shared libraries: libthinkfinger. so.0: cannot open shared object file: No such file or directory

You can execute sudo ldconfig to solve the problem.

You need to input three test fingerprints.

Sudo tf-tool -- verify

Verify that it can be correctly identified

Sudo mkdir-p/etc/pam_thinkfinger

Create the required directory

Sudo gedit/etc/pam. d/common-auth

Modify the/etc/pam. d/common-auth document

#

#

Auth sufficient pam_thinkfinger.so

Auth required pam_unix.so try_first_pass

Sudo tf-tool -- add-user YOUR_USER_NAME

After the system is restarted, add the user name you need to call the Fingerprint Authentication Module.

This completes

Enter your username to be verified when you enter the system

Password or swipe finger will be prompted

We can change it to a Chinese prompt.

Decompress the compressed package and enter the PAM folder.

Open Pam_thinkfinger.c.

Replace Password or swipe finger with (the Chinese prompt you want to display)

For example, enter a fingerprint.

Then compile and install it.

It feels great to install it. However, it is not stable.
