HOWTO: Fingerprint reading in Ubuntu with fprint

[speedisso]

the program is working great for me, the bad thing is that i can my fingerprint and after that i want to verify it...and guess what ? doesn´t recognized it

[camofish]

Trying to use the versions in the Intrepid repo of both fprint and thinkfinger results in hardware not found, even using sudo, on my Vaio VGN-TZ130N. Any ideas?

Everything else works splendidly with minimal effort which says a lot about the impact of this thread!

Hey thanks chase809

I was looking long time for the causes about that problem

A real help that appear like a surprise and in a place looking for other subject..

I was having the same problem until I realized that I can insert the

auth sufficient pam_fprint.so

into any pam.d file. So instead of entering this into the common-auth which is pulled by most files/auth methods I insert this line into the functions I wish to have my finger reader. For example if I want my finger reader to unlock my screensaver I inserted it into the gnome-screensaver (above the include common-auth section). The final product looks like this.

auth sufficient pam_fprint.so
@include common-auth
auth optional pam_gnome_keyring.so

Now my finger reader works for just my gnome-screensaver and doesn't cause my policy kit to lock up. I have a feeling the pam_fprint.so has not been developed for the new policy kit in 8.04. Hope this helps, you can explore with different pam.d files and turn the finger reader on or off.

I have an ASUS F6A with this fingerprint reader :

Bus 002 Device 002: ID 04f2:b029 Chicony Electronics Co., Ltd

The first time I have used the reader, it worked well :

campo@enterprise:/usr/src/fprint_demo-0.4$ sudo pam_fprint_enroll
This program will enroll your finger, unconditionally overwriting any selected print that was enrolled previously. If you want to continue, press enter, otherwise hit Ctrl+C

Found device claimed by AuthenTec AES1610 driver
Opened device. It's now time to enroll your finger.

You will need to successfully scan your Right Index Finger 1 times to complete the process.

Scan your finger now.
Enroll complete!
Enrollment completed!

but the second time it didn't work :

campo@enterprise:/usr/src/fprint_demo-0.4$ sudo pam_fprint_enroll
This program will enroll your finger, unconditionally overwriting any selected print that was enrolled previously. If you want to continue, press enter, otherwise hit Ctrl+C

Found device claimed by AuthenTec AES1610 driver
aeslib:error [do_write_regv] bulk write error -2
fp:error [fp_dev_open] device initialisation failed, driver=aes1610
Could not open device.

Someone can help me ? Thanks in advice for the answer and sorry for my english.

P.S. I have a Kubuntu 8.04 with custom kernel ( 2.6.28 )
P.P.S. I think that the reader remains locked so fprint_demo couldn't open device.

i did that, first i couldnt log on, and then the X server failed on me!

Nicely done... seems to (almost) work. I have a AES1610, supposedly support. I use sudo to execute both pam_fprint_enroll and/or fprint_demo:

$ sudo pam_fprint_enroll
This program will enroll your finger, unconditionally overwriting any selected print that was enrolled previously. If you want to continue, press enter, otherwise hit Ctrl+C

Found device claimed by AuthenTec AES1610 driver

Scan your finger now.
Segmentation fault

The segmentation fault occurs in both the gui and with pam when I swipe my finger. Any ideas?

I can't run aes2501 on my HP nc8430, ubuntu 8.10 amd64.
Here are the details:

$ lsusb
Bus 003 Device 002: ID 08ff:2580 AuthenTec, Inc. AES2501 Fingerprint Sensor

$ sudo apt-get install aes2501-wy
$ sudo apt-get install libfprint0 libpam-fprint fprint-demo

All went fine.

$ sudo aes2501
argc=1 Initializing, please standby...
No device found

$ sudo fprint_demo
aeslib:error [do_write_regv] bulk write error -2
fp:error [fp_dev_open] device initialisation failed, driver=aes2501

It shows the device with a status message "Could not open the device".
Any idea? Thanks!

same problem here with AES1610 on Intrepid 64 bit

I didn't read all the posts here and don't know if anyone already has mentioned it. I think that in point 5 of the Howto it should be

auth sufficient pam_fprint.so
auth requisite pam_unix.so nullok_secure

instead of auth required in the second line.
When there is auth required, my computer asks me always to enroll my finger AND to insert a password. When I change it to auth requisite, it only asks me my password if the fingerprint authentication failes.
