Login using USB key

[spartanx86]

I'm running Ubuntu 8.04.2, is there a method of logging into the OS using a USB drive?

Basically I want the USB drive to act as a key to login instead of a username and password.

sudo apt-get install libpam-usb
zcat /usr/share/doc/libpam-usb/QUICKSTART.gz|less

sudo apt-get install libpam-usb
zcat /usr/share/doc/libpam-usb/QUICKSTART.gz|less


what does that code do really

[cdenley]

It installs the PAM module for USB authentication, then it displays a compressed text file installed from the package containing instructions for how to configure and use the module.

Very interesting, thank you for that information.

Great! Just what I was looking for ... :D

EDIT:

Everything is working fine ... but note the following.
Tested on Ubuntu 8.10

PAM Module *IMPORTANT*
According to the site above:
Locate the following line on /etc/pam.d/common-auth or /etc/pam.d/system-auth:

auth required pam_unix.so nullok_secure

And change it to look something like that:

auth sufficient pam_usb.so
auth required pam_unix.so nullok_secure


For Ubuntu 8.10, the above would cause strange behaviour, instead change it to the following:


auth sufficient pam_usb.so
auth [success=1 default=ignore] pam_unix.so nullok_secure

I too wanted answer to this problem. Now I cleared of it. Thanks

Great tip indeed, I did not know of a libpam-usb package.
I'll look into it tonight, thanks :)
