nmap strangeness on OSX

Posted on August 19, 2011 by

So I had a need to scan some hosts with nmap — in particular because ARD was too slow and tended to crash a lot scanning large networks, but also because I wanted to automate the process. nmap seemed like it would would fit the bill pretty easily. A basic ping scan as tested from […]

10.6 Server upgrades

Posted on September 14, 2009 by

This weekend I upgraded some of my home servers to 10.6(.1) server, using the developer keys. I wouldn’t say that it went ‘without a hitch’ or even smoothly, but overall it wasn’t bad. The first machine to get 10.6 was the one with the most complex setup. It was an OD master, mail server, and […]

WWDC 2009

Posted on June 21, 2009 by

Another Apple WorldWideDevelopersConference has come and gone. Yet again it was sold out, with well over 5000 attendees. That makes for some crowded sessions, and even more crowded mens rooms. This is a relatively expensive conference to attend, but it’s really more like training than a ‘conference’, in that the sessions are fairly technical in […]

Leopard bug: cannot click on anything

Posted on May 14, 2009 by

Several times now I’ve had one desktop get into a mode where you cannot click on anything. You can use the keyboard to navigate between apps and everything seems to work normally, except mouse clicks. At first I suspected my wireless mouse, but after trying a few alternative mice, I ruled that out. The first […]

mushroom cloud computing

Posted on March 29, 2009 by

Wow, this cloud computing is really going to solve all the It problems. This great magic black box has more power than Virtualization, it’s stronger than any soap/caml/etc. middleware, able to leap thin clients in a single bound, outbattles SAN anything, laughs at client-server computing, scoffs at the mere mention of object-orientation. It’s daBomb. As […]

MSI Wind PC (7418)

Posted on March 3, 2009 by

In my current quest to modernize my home server farm, I picked up one of the new intel ATOM based machines. I chose the MSI WIND PC mostly because of price. The ASUS eee desktop looks much slicker and comes mostly complete, but I was aiming at replacing my dns/firewall machines, so I didn’t need […]

XSAN2.1 + 10.5.4 == SLOW

Posted on September 3, 2008 by

As detailed in my previous entry from May, Academic Technology at UK preformed a very agreessive large-scale infrastructure update this summer. Or at least we tried…. The ‘Cylinder of Destiny’ worked just fine, took plenty of hard work to arrive at the correct client settings, get all the clients bound to AD, etc. But after […]

Leopard & AD @UK

Posted on May 11, 2008 by

During the summer of 08, we’re replacing most of the OSX servers and upgrading the rest to 10.5. As part of the overall set of summer updates, we are also going to utilize AD for authentication where ever possible. Currently we run two 10.4 servers bound to AD (only, no local OD or MT) which […]
