How to briefly describe the application of Fedora 8 fingerprint in Linux system, aiming at this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

We recommend Fedora 8 fingerprint recognition which is very good to use, such as let you have some understanding of Fedora 8 fingerprint recognition, and then give a comprehensive introduction to Fedora 8 fingerprint recognition. I hope it will be useful to you. I am so happy that Linux Fedora 8 fingerprint recognition has been successful for a few days!

Although in the process of groping a lot of detours, soak in a lot of foreign forums, to * found that the realization of this function is so simple, it is really a bit sad and happy! But it worked! Ha ha, have fun!

The way to install Fedora 8 is

Yum install libfprint

Yum install pamfprint

Yum install frpint_demo

And then you can use it!

1. Fedora 8 input fingerprint method:

1. Available fprint_demo

two。 Type: pam_fprint_enroll-- help at the terminal to check the help!

2. Fedora 8 fingerprint authentication:

Configure in / etc/pam.d/system-auth, the specific configuration is to add a line of authenticated configuration! The configuration is as follows:

#% PAM-1.0

# This file is auto-generated.

# User changes will be destroyed the next time authconfig is run.

# auth sufficient pam_fprint.so

# auth required pam_unix.so nullok_secure try_first_pass

Auth required pam_env.so

Auth sufficient pam_fprint.so

# auth sufficient pam_unix.so nullok try_first_pass

Auth requisite pam_succeed_if.so uid > = 500quiet

Auth required pam_deny.so

Note: pay attention to the bold part! The above bold behavior adds the Fedora 8 fingerprint identification verification module, and the following line in bold has been annotated for the system's original password verification module! If the two behaviors are not annotated, fingerprint identification and password verification will be carried out first, and the security will be enhanced. If you want to be lazy, people like me, do not want to enter the password every time so troublesome, just need to verify the following password notes, then only need fingerprint authentication!

This is the answer to the question on how to briefly describe the application of Fedora 8 fingerprints in the Linux system. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
