FINGER PRINT READER

Next thing was to protect my system from unauthorized user , m1530 has a got a finger print reader .To use it in ubuntu u can there is a package called thinkfinger

Install thinkfinger-tools and libpam-thinkfinger:

sudo apt-get install thinkfinger-tools libpam-thinkfinger

now acquire the finger print with this command

sudo tf-tool –acquire

to test u r fingerprint

sudo tf-tool –verify

now how to use it daily,as everyone Linux has lots of config files now we need to edit one of those

/etc/pam.d/common-auth

modify it as
#
# /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_thinkfinger.so
auth required pam_unix.so try_first_pass nullok_secure

and don forget to acquire a fingerprint
now done with finger print reader.
