pyFreeDnsUpdate is a command line python script that updates the FreeDNS record for a given domain to the current public facing IP address detected by the local host.
It requires a one time edit to configure a list of domain|api_key pairs, and after that it can be run as a chron job to perform a sync check and update push if needed.
Activity is logged on a local text file, and DEBUG level can be enabled in case of troubles.
MergeSafBookmarks (recently shortened to merge bookmarks) can be used to push bookmarks into Safari. Brought to you by 318 Inc., this tool allows you to mass deploy bookmarks to a large number of systems quickly and efficiently.
