I wanted to be able to define nfs shares with puppet and have puppet take care of the exports line and exportfs. I found this page, but I didn't like that there was perl code thrown in the midst. I rewrote it to use an inline template instead.

I wanted to configure rate limiting on our exim server and needed to setup an ACL that I could include in multiple spots in the configuration. The keyword acl = acl_name is supported (referred to as nested ACL's) but the logic took a little bit of thought...

I want to ratelimit users, the acl for that is here:

warn authenticated = *

I ran into a snag when trying to update the bios on my PE R210ii, the Bios update is 8MB, too large to fit on a floppy image, so I needed to make a floppy image large enough for the file. I tried increasing the size of the Dell floppy image and that didn't work, so I had to start from scratch with a boot floppy made from windows. Funny enough the first link that came back in my google search was that of my coworker.

I've run into this enough times that I thought I'd write a little script to do the work for me.
It's just a simple one line call to python, but I wrapped it with some argument parsing.

It's a python script that takes a password and returns the salted sha512 hash by default. sha256 and md5 can be specified with switches.

We maintain multiple repositories, many of which have the same rpms repeated in different locations. In order to save space we use hardlinking extensively. The hardlink command does an ok job of finding things to link, but we are only really interested in rpms and don't want repomod.xml or comps getting linked so I wrote a little python script to hard link all the rpms based on a checksum. The script is over at my github. hardlink_rpms
