    Mac OS X: Repairing Drop Box Issues in Leopard

    Peer-to-peer networking can be very easy with Mac OS X.  But due to an issue with ACLs it can be a little annoying in the Leopard release of Mac OS X.  Essentially, when files are copied to the drop box, they aren’t accessible by the owner of the drop box due to an ACL issue.  To repair, run this command, replacing short_name with the username that has the dropbox: chmod +a "short_name allow list,add_file,search,delete,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,writesecurity,chown,file_inherit,directory_inherit" /Users/short_username/Public/Drop Box

    Mac OS X Server: changeip no mas?

    In this article: http://docs.info.apple.com/article.html?path=ServerAdmin/10.5/en/c7sa13.html Apple states that you no longer need to use the changeip command with Mac OS X Server: You can change the IP address of a server using the Network pane of System Preferences or the networksetup tool. When a network address change is detected, no matter how the change happened, changeip is invoked. The tool changeip goes through all configuration files and places where the Server’s IP address is stored, and changes the address to conform to the new address. The server’s IP address can be changed without changeip being invoked from the command-line.

    Xsan: Adding Client Computers

    Now that you have created your volume you will want to move on to adding computers that can access your volume. This is one place where Xsan 2 is very different than Xsan 1.x. To add a computer that has access to your volume, click on Computers in your SAN Assets list. From here, click on the + sign in the lower right hand corner of your screen. This will invoke a list of computers that have the Xsan software installed (as can be seen below). You can add clients of 1.4.2 or 2.x to your SAN. You can also add clients running 10.5.0 through 10.5.2; however, you will receive…

    Exchange 2007: Change Default Domain with PowerShell

    Your users sick of typing in their domain name in the OWA auth screen?  Well, here’s the PowerShell command to make it where they don’t have to any more: Set-OWAVirtualDirectory -Identity “owa (default web site)” -LogonFormat username -DefaultDomain krypted.com  Since you’re not using https://krypted.com/ as your mail domain swap that out with your domain name of course.  And if you want to use it for the other virtual directories of OWA, such as Exadmin then run it again swapping out the owa with the VD you’re using.  Oh, you can do it through the Exchange Management Console too, but the GUI isn’t as much fun.  But if you do decide…

    LOPSA + SAGE + USENIX = l@m3

    I got the following email from LOPSA (of which I am a member).  I’m at a loss for words and am now unsure as to why I am a member of either organization.  The whole affair seems completely in contradiction to my opinions of all things *nix… Dear Charles,  As you may be aware, LOPSA was sued as a third-party defendant by the  USENIX Association in April 2008, as part of a lawsuit brought by  Association Headquarters, Inc., against USENIX to recover for services  AH provided to LOPSA for which USENIX is allegedly responsible.  LOPSA  secured legal counsel at the time and has been involved in the pre-trial  phase of…

    Georgia Drops Tennessee

    The Bulldogs today keep their hunt for a National Title birth alive by knocking off the Tennessee Volunteers.  A win over the Vols, who beat Georgia last year, blocking them for the National Title will likely propel the Dawgs up in the rankings after a little more movement in the top 10.  Next up, Georgia has to run the gauntlet against Vandy, LSU and then Florida, all in the top 25.  If Georgia can successfully navigate this maelstrom then they should be sitting pretty moving into the last 3 games of their schedule, which includes Auburn, #20 in the nation.  The Georgia schedule is noted as the hardest in the…

    Xsan: Installation

    Install Xsan software and Reboot. This will install a bin, config, debug, examples, man and ras folder into your /Library/FileSystems/Xsan folder.

Once you setup the SAN it will fill in with more information. Next you will want to place the Xsan Admin application in your dock and open it for the first time. Once open, you will be faced with the Introduction screen. Xsan 2.0 Introduction Screen Here you will click Continue. In…

    Windows Server 2008: Expanding a Volume

    You may find that a disk in Windows Server simply isn’t big enough for your greedy applications.  But never fear, the good folks at Microsoft have given us the ability to expand that volume on the fly, as needed by adding other pools of storage or single disks to it.  However, it’s important to keep in mind that if you have a highly available volume (let’s just say a RAID6) and you add a single disk to it then you have just effectively lost the high availability for the data stored on the extended portion of the volume.  So make sure that the new storage you are adding matches up…

    MacWorld Talk Posted

    Leopard represents a massive leap forward in security features included with Mac OS X. As the needs of users of OS X have matured so has the ability for systems administrators, developers and end users to secure their systems. One of new security features is Sandbox. Since it’s inception, Mac OS X has had permissions that can be applied to files allowing the ability to block access to specific applications. But Sandbox gives you the awesome new ability to apply permissions to what specific applications can have access to. In this session we will review what an application can access and how to harness Sandbox to restrict access to networking,…
