Been busy with sysadmin-like stuff at home. First I got the amanda backup system working.. not a big deal in itself, it's just a bit of rtfm and grokking it. Then I took on a bigger challenge, getting a one-time-password login working. I found OPIE and pam_opie but both weren't that well-documented and showed 'test software' and 'not very well maintained lately'. Being stubborn I still managed to configure and build it all and make it run as planned. I am writing down how I did that so other people can share the solution.
