ianw1974 Posted April 4, 2008 Report Share Posted April 4, 2008 I wondered if any of you have a fingerprint scanner on your laptop, and if you've attempted to use it under Linux? I tried it once under Windows, and it let me scan a few times, obviously to get an average scan so that it would always allow you to sign in no matter what position your finger was on the fingerprint scanner. Then yesterday, I decided to install pam_fprint so that I could authenticate with Linux. Once enabled in /etc/pam.d/system-auth, it does work and allow you to sign in from console window as well as under gdm as well. The problem is you can only scan the finger once, and after that it's very hit-and-miss to whether you can authenticate with it or not. Luckily I didn't set it to use just fingerprint, so if it failed to scan properly, I could just give my password. I have since disabled it, since I was scanning all the time, and never getting a clean scan and so could never sign in with it. I always ended up giving the password. Anyone else got any experience with this, or just never thought about trying it? Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted April 4, 2008 Author Report Share Posted April 4, 2008 OK, did a bit of slower scanning and now I think it's working a bit better.

aphelion Posted April 4, 2008 Report Share Posted April 4, 2008 I wondered if any of you have a fingerprint scanner on your laptop Are these laptop exclusive, I guess they wouldn't be, but you use laptop, just curious. How much would one of these cost approx? Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted April 4, 2008 Author Report Share Posted April 4, 2008 I have a HP Business Notebook 6710b, and it wasn't overly expensive. I would say about 500 GBP in the UK. I bought it in Poland, and it was about 3000zl or so back in October 2007. I've seen quite a few HP laptops with these and I expect they will come more popular soon. I seem to have it working fine now, but I've not logged out to try in gdm yet, but it does prompt you for it when I was testing last night. How to on my website: Howto: Fingerprint Authentication nice and simple :) Quote Link to comment Share on other sites More sharing options...
Guest icepick Posted April 11, 2008 Report Share Posted April 11, 2008 HP/Compaq nc8430 AuthenTec AES2501 Mandriva 2008 Spring I was trying, but I kept having problems with the driver: Found device claimed by AuthenTec AES2501 driver aes2501:error [dev_init] could not claim interface 0 fp:error [fp_dev_open] device initialisation failed, driver=aes2501 Could not open device. A google search made me thing this had something to do with usb permissoins, but I was unable to resolve them. In other Linux variants, usbfs is still mounted through fstab that doesn't appear to be the case with Mandriva. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted April 12, 2008 Author Report Share Posted April 12, 2008 I don't have usbfs mounted on my system through fstab. I haven't tried Mandriva, but might give it a go from the Mandriva One CD if it's possible. Quote Link to comment Share on other sites More sharing options...

ianw1974 Posted April 30, 2008 Author Report Share Posted April 30, 2008 The problem is your scan was done too fast, which is why it asked for your password - it didn't recognise your fingerprint. I have it working fine once I did the scan slower originally when I created the fingerprint image. Quote Link to comment Share on other sites More sharing options...

No, too many failed scans look like this: $ su Scan left index finger on AuthenTec AES1610 Scan didn't quite work. Please try again.

Password: and in kdm I first have to my password and then have to succesfully scan my finger to login Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted May 1, 2008 Author Report Share Posted May 1, 2008 Hmmm strange, with gdm it only asks for fingerprint and only password if it fails reading it. Quote Link to comment Share on other sites More sharing options...
scarecrow Posted May 1, 2008 Report Share Posted May 1, 2008 A google search made me thing this had something to do with usbpermissoins, but I was unable to resolve them. In other Linux variants, usbfs is still mounted through fstab that doesn't appear to be the case with Mandriva. Try adding to your /etc/fstab something like none /proc/bus/usb usbfs devgid=XXX,devmode=664 0 0 The devgid number could be the one of your main user's primary group, while the devmode one can be changed to 666 (accepting a slight security risk), if 664 does not work as it should.
