Enabling finger print login in ubuntu Linux

lionlix — Mon, 12 Oct 2009 13:00:15 +0000

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/

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/.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

it works for me

VirtualBox USB solution on ubuntu linux

lionlix — Sun, 11 Oct 2009 11:26:15 +0000

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

NOTE: 123 is the group id you can get that id by this command “grep vboxusers /etc/group”

it works for me
ubuntu 9.10
virtualbox 3.0.8
