If you ever need to move binary RRD files between architectures, you need to dump them to XML on the old host and restore them as binary on the new host. The following bash loops do this quickly and simply. Converting binary RRD files to ASCII XML: for x in `ls *.rrd`; do NAME=”$(echo “${x}” […]

I needed a TFTP server for Windows that didn’t completely infuriate me, so after many candidates, I settled on SolarWinds TFTP Server. Just sharing.

I’ve received a lot of comments on my MacOS X Login with 802.1x post, so it’s time for an update! I have no idea what the real XML structure for loginwindow is. What I have is some trial and error, fragments from searches, and adding the items using ‘defaults write’. Some (most?) of it can […]
