    Mac OS X Leopard: What About that ZFS Thingie?

    I originally posted this at http://www.318.com/TechJournal ZFS was released by a team at Sun in November of 2004. The name stands for “Zettabyte File System”. ZFS is a 128-bit file system, so it can store 18 billion billion (18.4 × 1018) times more data than current 64-bit systems. We’re not going to sit here and do the math for that but you are more than welcome to figure out what the theoretical size is at that point – all we can say is that it’s friggin’ huge. Traditional file systems reside on single devices and require a volume manager to use more than one device to generate a logical or…

    Mac OS X Server: Mailbfr update

    I originally posted this at http://www.318.com/TechJournal Mailbfr, spamtrainer and amavis-stats are great packages that fit into Mac OS X Server. The guys from topicdesk have been kind enough to post an overview on how their products work under Leopard and how the changes in Leopard impact their utilization.

    Football: Georgia vs. Troy

    44-34.  The Troy Trojans gave us fits compared to some of the other opponents we’ve had.  They’re not half bad.  We still won, but I would have expected the score to be a bit more lopsided…

    Citrix and XenSource

    I originally posted this at http://www.318.com/TechJournal It seems like everyone wants to dabble in the Open Source market these days. First came the RedHat, VA Linux and other public companies using Open Source technologies to ramp up. Then IT giants such as Novell, Sun and Apple started to come to markets with products faster due to their newfound Open Source roots. Now a lot of other companies are jumping on the bandwagon and introducing products based on Open Source technologies or purchasing other companies to help them do so quickly. Citrix has purchased XenSource, a company that provided virtualization products based on the Xen Open Source virtualization platform. XenSource is…

    Mac OS X Server 10.5: Sharing Files the New Way

    I originally posted this at http://www.318.com/TechJournal We’ve gotten a few questions from people asking how you’re supposed to setup share points for Leopard Server. It’s relatively simple but will require a little getting used to for those who are used to configuring sharing options in Workgroup Manager. To view the shared folders on a system, open Server Admin and click on the name of the server in the SERVERS list. From here, click on the File Sharing button in the Server Admin toolbar and you will see a list of the logical volumes that your server can see along with a handy Disk Space image showing how full the various…

    BarCamp in LA

    I originally posted this at http://www.318.com/TechJournal There’s an open source conference of sorts coming up in LA on November 3rd. It’s called BarCamp. Check it out at: http://barcampla.org/ We start by gathering together in one space and going around the room to introduce ourselves with three tags to describe what we’re passionate about (or want to talk about). There will also be some announcements. After this, people who intend to lead a session will add their session info to an empty schedule grid (may be moved around early on). If you see a session you’re interested in, go to it. After a couple of sessions, you will have a significant…

    Mac OS X Server 10.5: Introduction to RADIUS

    I originally posted this at http://www.318.com/TechJournal Remote Authentication Dial In User Service (RADIUS) can help to take the security of your wireless network to the next level beyond standard WPA authentication. Prior to Leopard RADIUS communications could be obtained using Elektron or OpenRADIUS running on OS X – but in Leopard no 3rd party software is required beyond Leopard Server. So how difficult is it to setup RADIUS on Leopard? You be the judge after reading this quick walkthrough. For the purpose of this walkthrough we are going to assume that you are using the Advanced Mac OS X Server style. Before you begin this walkthrough, make sure that the…

    Mac OS X: New Trojan Discovered

    I originally posted this at http://www.318.com/TechJournal Monday, October 29th, 2007 – Intego issued a security alert about a new Trojan Horse called OSX.RSPlug.A targeting the Mac. OSX.RSPlug.A changes the DNS (Domain Name Server) address that infected systems use to access web sites and installs a new task on infected systems to change the DNS server again if the end user changes it back to what it was before. This is similar to many attacks against the Windows Hosts files. However, if anyone is going to get this worm they have to authenticate as an administrative user for their system to get infected. OSX.RSPlug.A has been found on some pornographic Web…

    Football: Georgia-Florida

    Ah, the memories.  Nights in Jacksonville, getting ready for the “Worlds Largest Cocktail Party” – heading out to the game, usually too early to be up – but rallying to go – and then loosing our shirts to a team in the title race. It never got any easier.  But today, we went out there, with all their hype and put up a 12 point win on the University of Florida.  Ya’ll can have your Heisman – we’ll take one sweet victory at a time. Till next year…

    Mac OS X Server 10.5: Self Updating Directory Entries

    I originally posted this at http://www.318.com/TechJournal If you’re migrating to Leopard and Leopard Server then you’ve likely noticed the welcome addition of a new program in /Applications/Utilities called Directory. Directory allows users bound into an Open Directory environment to update LDAP records provided they have access to do so. Using LDAP ACLs it’s possible to give users access to update their own directory information using an LDAP directory browser such as Directory. When you open Directory you should see a listing of all of the directory information that has been created. From here you can create Shared Contacts, Groups, Locations and Resources. Each of these can be connected to a…
