I had a problem to fix a few months back where by something like 1000 users had totally bricked their home folder permissions. Trying to propagate permissions from Workgroup Manager (it was a 10.4.11 server) kept hanging and would only fix home folders up to the letter “d.” It was at this point I was called in to write a script so a colleague could repair the permissions without running the risk of annihilating the home folders from the command line.

A while back I was asked by a colleague if I could automate starting a number of SSH connections based on the current selection in ARD. This may seem pointless given that you can run UNIX commands in ARD but it is not. With SSH you get an interactive shell; quite different from just being able to send commands and receive a sample of the response! MORE »
OS X features a software firewall for typical users but also includes ipfw, a fully featured firewall capable of facilitating all the traffic routing needs of clients and servers alike.

If you’ve ever worked with an OS X server you will have come across the Directory Administrator. The Directory Administrator is essentially the all-powerful user in an Open Directory (OD). This user is created when promoting a Mac server from a standalone machine, with only a dslocal directory, to an Open Directory Master (ODM.) MORE »
Apple Remote Desktop is an invaluable tool in the Mac sysadmin world providing functionality above and beyond the likes of VNC. There are however, a few things that we can’t do. For a lot of really geeky work we need an interactive shell via SSH. The problem is ARD only provides a simple Send UNIX command utility that pales in comparison to a fully functional SSH connection.
I made an applescript for a colleague of mine who wanted to be able to SSH a selection of machines in ARD. It’s not too smart as it doesn’t pull usernames or passwords from anywhere but it does speed up opening a connection to a target machine. MORE »
There are lots of ways of generating passwords. We can use dashboard widgets, desktop applications or even websites. I’ve recommended GRC’s password generator in the past (https://www.grc.com/passwords.htm) as it’s quick and easy.
