Talk:Integrated Fingerprint Reader

I was just wondering what was happening with this, it would be really great for this to work.

Slashdot posted about linuxbiometrics.com, and I found this forum post there.

There is a possibility that a beta program will be occuring around August or Sept. this year '05. Keep your eyes (or news aggregator) on linuxbiometrics.com for the latest announcements.

Fingerprint reader hiccups

any body else notice that the fingerprint reader doesn't work very well or doesn't work at all if you have been using the notebook for sometime?

I'm thinking because of the heat generated from the hdd

HowTo :)

Disclaimer: This is how I got the fingerprint reader on my T43 to work. It can _NOT_ yet be used to log me into the system. Working on that,

This is on ubuntu breezy.

get all required devel libs and tools (gcc, g++, pam-dev, etc.) I could not compile bioapi with the graphical Qt tools

• wget http://www.qrivy.net/~michael/blua/bioapi/bioapi-1.2.2.tar.bz2
• tar xjf bioapi-1.2.2.tar.bz2
• cd bioapi-1.2.2
• ./configure --with-Qt-dr=no
• make

then as root

• make install

beware that checkinstall will not work! go to http://www.qrivy.net/~michael/blua/upek-bsp.html and download TFMESS_BSP_LIN_1.0beta2.zip unzip it into a seperate folder, as it will not create one as root

• sh install.sh
• chmod 777 -R /usr/local/var/bioapi/

actually this depends on where you installed, if you did as i wrote, it should work otherwise you probably know what you're doing anyways :)

• touch /var/log/BSP.log && chmod 666 /var/log/BSP.log
• chmod 666 /proc/bus/usb/`lsusb | grep "0483:2016" | sed -e "s/Bus\ \(.*\)\ Device\ \(.*\):\ .*/\1\/\2/"`

now go to the folder where you extracted TFMESS_BSP_LIN_1.0beta2.zip

• cd NonGUI_Sample
• ./Sample

Now i hope it works, otherwise mail me: t43fingerprint@badcode.de

Another thing i got to work: gdm login with pam_bioapi *freu*

what i did:

• wget http://www.qrivy.net/~michael/blua/pam_bioapi/pam_bioapi-0.2.1.tar.bz2
• tar xjf pam_bioapi-0.2.1.tar.bz2
• ./configure && make

as root

• make install

now use the sample tool from the fingerprint reader to create <username>.bir <username> _must_ be the username you want to login with, gdm broke for me for any login name that had no .bir file

try:

• BioAPITest | grep -A2 Fingerprint | tail -n1 | cut -b 12-

it should print something like "{5550454b2054464d2f45535320425350}" if it does:

• mkdir /etc/bioapi1.10/pam`BioAPITest | grep -A2 Fingerprint | tail -n1 | cut -b 12-`
• cp <username>.bir /etc/bioapi1.10/pam`BioAPITest | grep -A2 Fingerprint | tail -n1 | cut -b 12-`

now comes a distribution specific part. on ubuntu i can modify /etc/pam.d/common-auth to look like this:

#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.).  The default is to use the
# traditional Unix authentication mechanisms.
#
auth    sufficient      pam_bioapi.so {5550454b-2054-464d-2f45-535320425350} /etc/bioapi1.10/pam
auth    required        pam_unix.so nullok_secure

and pam immediatelly starts to use the fingerprint reader to do local authorization (e.g. sudo/gdm use the fingerprint reader) I found this out by try and success, if this is plain wrong, wikorrect me :) Now my gdm pops up a (ugly) image to swipe my finger and... magic I can login without a password

I'd be glad to help out if you have questions.
