Enabling finger print login in ubuntu Linux

if you have a finger print in your laptop and you want to use it for finger authentication follow these steps :

1- use the hard way and compile the thinkfinger software from http://thinkfinger.sourceforge.net/

or

install it from repository apt-get install libpam-thinkfinger  libthinkfinger0 thinkfinger-tools

2- run this command tf-tool –acquire to create a finger print .bir file

3- move the .bir  to the pam thinkfinger folder mv .thinkfinger.bir /etc/pam_thinkfinger/<user id>.bir

4- run this command sudo /usr/lib/pam-thinkfinger/pam-thinkfinger-enable

5- Modify the file /etc/pam.d/common-auth so it looks like :
#
# /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

VirtualBox USB solution on ubuntu linux

when you install VirtualBox you wont be able to enable the usb devices on the guest os, the solution for this is to do the following:

1- add yourself to the vboxusers groupe in /etc/group
2- add this line “none /proc/bus/usb usbfs devgid=123,devmode=664 0 0″ to the /etc/fstab at the end

it works for me
