Useful Commands for OSX Administration

Over the years I have stored a file that has many of the day to day commands that I use to administer the computers at my workplace. After 4 years of saving these commands I am giving back and creating the ultimate post to aid all new sys admins out there. The Adaptive Firewall The most basic task you can do with the firewall is to disable all of the existing rules. To do so, simply run afctl (all afctl options require sudo) with a -d option: afctl -d When...

Export OSX Wiki Server to CSV

Recently our Organization has grown to immense size and we are starting to outgrow the 10.6 Wiki server that we use primarily for our intranet. I have been looking at the 10.7 wiki server however it is not much better, our intranet has been plagued with bouts of corruption and plist issues that have caused slow load times, and extreme data loss. Its pretty clear that we need to move to a more stable information storage media. We have looked at WordPress and Drupal for this functionality however the biggest...

10.7 Server throttle high CPU usage script

For the last two years, I have noticed a trend.

10.7 Server Web Administration: Missing Manual

I just started using 10.7 Lion Server at my organization and I have to admit it is nice in some ways and infuriating in others. Apple has certainly fixed and introduced quite a few new features such as Profile Manager but have removed features like Mobile Access. The hardest hit service in my opinion when it comes to 10.7 server administration is the Web service. Apple has stripped this service completely out of the Server Admin app and has added a dumbed down version of the service to the Server...

Stay off of blacklists: Limit postfix recipients

I have heard this story it seems over and over again, I also have been the topic of many email horror stories. They usually go like this “I just setup a new server and within days we were on a corporate email blacklist, I contacted the company in question and asked why are we on your blacklist, why won’t you deliver our email. They shared with me an email log of thousands of emails being sent from my mail server through several legitimate email accounts. I ensured that my server...
