File Distribution Using rsnyc
The following script is used to distribute account files to different computers using rsync over ssh. Of course, it is important to note that the computer that runs this script as a cron job is the only computer that account files should be edited on. This includes hiding or aliasing the "passwd" command from users on the other machines. Also, if you want the ssh login to work automagically, you'll have to setup ssh keys.
However, maybe somebody with a little more drive can write up a script to run on all machines and merge changed files.
