Not sure what that last bit meant? Here is how to get a copy of your OTP.
Fast way
========
* Open a terminal
* Press yubikey button
It will output an OTP into the shell:
------
$ cccccccgklgcvnkcvnnegrnhgrjkhlkfhdkclfncvlgj
bash: cccccccgklgcvnkcvnnegrnhgrjkhlkfhdkclfncvlgj: command not found
------
This can be pasted into the Modhex_Calculator page.
Harder way
==========
This requires you to have the pam module enabled with 'debug' turned on. When
prompted for the yubikey press the button. The pam module will print out debug
information including the OTP and ID of your token to the shell - copy the ID
into your config file and you should be up and going.
