Here's a link to a comprehensive server script for Linux servers by Relliktsohg, et al. Performs Start, Stop, Backup, Cartography, Update, and more. Can easily be called as a cron job for nightly jobs. Has a lot of users, many recent updates, and a lot of support in that thread.
I would like to see someone create a topic, a poll, of what the best admin software is. The first post in this thread hasn't been updated since august. The information it provides is pretty useless at this point IMO. I would really like to see some updated information of all the available admin software in one place.
I would create the poll myself, but I don't know the names of "all" the currently available administrative software programs.
