Ubuntu8.10T61 enable the fingerprint Function

1. Search for thinkfinger from Ubuntu8.10 and find three software packages. Some people on the sudoapt-getinstallthinkfinger-toolslibpam-thinkfingerlibthinkfinger0 network said that their own compilation and installation, I feel so bitter. 2. enable the fingerprint function sudo/usr/lib/pam-thinkfinger-enable online

1. Search for thinkfinger from Ubuntu 8.10 and install the three software packages.
Sudo apt-get install thinkfinger-tools libpam-thinkfinger libthinkfinger0
Some people on the Internet say that they have compiled and installed their own files. What do I think.

2. Enable the fingerprint Function
Sudo/usr/lib/pam-thinkfinger-enable
Some articles on the Internet said that some configuration files need to be manually modified. After I opened the configuration file, I found that the configuration file has already been modified without manual intervention.

3. restart the system
Otherwise, the following three errors may be reported during subsequent steps:
Undefined error occured (0xff ).
Or
Warning: usb_bulk_read expected to read 0x40 (read 0x10 bytes ).
Or
Cocould not acquire fingerprint (communication with fingerprint reader failed)
Countless people have reported the above three errors, and I have encountered them one by one. However, it was easy to restart this step.

4. Recording fingerprint
Sudo tf-tool -- acquire
There is an article on the internet saying that sudo is not added here, but if I do not add sudo, it will always fail. So we had to log on to sudo first, and then change the owner of the generated fingerprint file from root to the current user. For example, if my username is sanhe, enter the following:
Sudo chown sanhe: sanhe ~ /. Thinkfinger. bir

5. fingerprint check
Tf-tool -- verify
Sudo is not added here because the fingerprint file has been changed to the current user. If you are prompted to pass the verification, all settings are complete.

I have to use tf-tool -- add-user to add users. However, my tf-tool only has parameters such as -- acquire and -- verify, there is no -- add-user parameter. I don't know why. After completing these five steps and then restarting, the fingerprint will be available.
This is recorded to show others.
