[Thinkfinger-devel] Updates, request for testing (again) and USB debugging support

[Timo Hoenig]

Hello everyone,

I've just committed quite a few radical lines to SVN. They should
change the compatibility of ThinkFinger to the better.

If you did *not* get ThinkFinger working reliably in the past it is now
time to give it a try. For your convenience, I have created a tar ball
of the current SVN revision [1].

If ThinkFinger still doesn't work for you, please make use of the new
USB debug option.

Just run './configure' as before and add the switch
'--enable-usb-debug' . When using 'tf-tool' or the PAM module you'll
get flooded by detailed USB logs which are of interest when analyzing
why things do not work as they were supposed to.

Everyone else who was a satisfied ThinkFinger customer in the past,
please check whether the recent changes did not break anything for
you :-) I never imagined how much pain such a little USB device as this
one can cause...

Thanks for the attention and have a nice day,

Timo

Current svn is tested and working on my R52 running Ubuntu edgy.

Thanks!

Hi Chris,

Thanks for the information, Chris. So far I could test T60, X60, T43p
and the external IBM/Lenovo USB keyboard with fingerprint reader.

[1] ThinkFinger SVN Revision 102

Works fine on my T42, Bus 003 Device 002: ID 0483:2016 SGS Thomson
Microelectronics Fingerprint Reader.

The only small problem I've found with --verify-user parameter:

#tf-tool --verify-user user --verbose

ThinkFinger 0.2.3 (http://thinkfinger.sourceforge.net/)
Copyright (C) 2006, 2007 Timo Hoenig <***@suse.de>

Running in verbose mode.

* Mode: verify
* Biometric identification record file: '/etc/pam_thinkfinger/user.bir'

Initializing... done.
tf-tool: TF_STATE_COMM_FAILED (254)
Could not acquire fingerprint (communication with fingerprint reader failed).

Regards,
Anton

Does this happen on a regular basis? Would you mind to compile with USB
debug support and send the log?

Thanks,

Are you sure that /etc/pam_thinkfinger/user.bir is a valid bir file?
What's its size?

you are right! It's 0 size and I also have user.bir.old.
I have regenerated that user and it stared to work again.
I have no idea why that happened.

So, now I have the follow files:
-rw------- 1 root root 170 2007-03-30 19:22 user.bir
-rw------- 1 root root 178 2007-02-17 10:16 user.bir.old
-rw------- 1 root root 174 2007-02-19 04:07 root.bir

As you can see it all has different size. Is it ok?..

Yes, that's perfectly fine.

However, I'll add some sanity checks for bir files which don't look
sane.

Thanks,

This is so true. kcheckpass (KDE) didn't work with previous version.
I even opened the bug:
https://bugs.kde.org/show_bug.cgi?id=142136

However it seems it was a bug of thinkfinger. I guess it was related
problem with heat (deinit?).
It's started to work fine with version 0.3.

So, you can try to unlock your KDE session. Press Enter first (it will
stop responding) and swap a finger. Now, there is another problem with
KDM. It will just crash if you try to login.
But this a story not for this mailing list ;) I'll try to find there
is the problem.
