The Bad Guys Will Cut Off Your Fingers - page 3
Thinkpad Fingerprint Reader on LinuxNow you need to edit your PAM (Pluggable Authentication Modules) configuration so you can log in to your computer with either your usual password, or with your fingerprint:
# mkdir /etc/pam_thinkfinger # tf-tool --add-user carla ThinkFinger 0.3 (http://thinkfinger.sourceforge.net/) Copyright (C) 2006, 2007 Timo HoenigConfiguring PAM is always a heap o' fun. On Debian, the Buntu family, and most Linuxes, add these lines to /etc/pam.d/common_auth before any other pam_unix lines:
Initializing... done. Please swipe your finger (successful swipes 3/3, failed swipes: 6)... done. Storing data (/etc/pam_thinkfinger/carla.bir)... done.
auth sufficient pam_thinkfinger.so auth required pam_unix.so try_first_passFor Fedora, PCLinuxOS, and the rest of the Red Hat extended family, add them to /etc/pam.d/system-auth. SUSE goes its own way entirely. Add uinput to /etc/modules, or whatever your system needs to load modules at boot, and reboot.
Now what happens? My T61 runs PCLinuxOS, and the graphical login manager has absolutely no clue about fingerprint readers. kdesu doesn't know what to do with it, either. So I can't login to a graphical session with my fingerprint. However, at the console prompt I got this:
PCLinuxOS release 2007 for i586 Kernel 220.127.116.11.tex1 on a Dual-processor i686 /tty4 ripley login: carla Password or swipe finger:
Hurrah! And it worked. It's still a baby and has lot of growing up to do, so please visit Resources for more help and updates. ThinkFinger needs more PAM modules to make it work with different types of authentication and applications, so if you're looking for a FOSS project to support that would be a good one.
