Tiny Deathstars of Foulness

I am almost embarrassed how long this took me to figure out. FaceTime was missing on my iPhone 4. Apparently, if you upgrade from 3 to 4 it doesn’t automatically show up. Instead you need to go to Settings and then tap on the Phone settings. Right there, staring back at you is a screen that says FaceTime and it gives you the ability to turn it ON or OFF. Tap ON and it should reappear in your apps (required me to reboot to show up).

Microsoft has published a number of scripts used to backup TPM (Trusted Platform Module) and BitLocker information for Windows clients. Windows Server 2008 and 2008R2 have support for the attributes required to centrally manage Microsoft’s BitLocker and TPM. Windows Server 2003 has the ability to run these (they require some searchFlags be set to confidential, so pre-2003 Active Directory cannot support these attributes). To extend the schema is pretty easy. To do so, use an administrative account for the forest (the administrator account for the first domain in the forest is a common one to use). Then log into the server running the schema operations FSMO role for the forest and download Microsoft’s ldif file with these attribute definitions from Microsoft. Once downloaded, use the ldifde command to import into your domain: ldifde -i -v -f BitLockerTPMSchemaExtension.ldf -c "DC=X" "DC=ad,dc=krypted,dc=com" -k -j . Once downloaded, check out the vb scripts that Microsoft has provided for key escrowing and other tasks here.

Microsoft has a great feature called autotuning. Autotuning though can be problematic when it comes to network connections with Microsoft Outlook, Internet Explorer 7, RDC and even some file sharing protocols over the WAN. This is mostly because not all firewalls support TCP Window Scaling for non-HTTP-based protocols. If you’re running into problems where these applications give you errors like “Outlook is trying to retrieve data from the Microsoft Exchange Server Exchange_Server_FQDN” then you can try disabling autotuning to see if that is your problem (usually this involves wan connections, btw). To disable autotuning, use netsh to set tcp for autotuninglevel to disabled: netsh interface tcp set global autotuninglevel=disabled To turn autotuning back on, just set the autotuninglevel to normal: netsh interface tcp set global autotuninglevel=normal

Tags: , , , , , in Lion is a pretty good app for most tasks. But I find myself frequently doing things that I don’t think developers intended me to do. One such item is setting up and tearing down Open Directory to test various iterations of enabling a master. I frequently use slapconfig to destroyldapserver: slapconfig -destroyldapserver Doing so almost immediately allows me to demote an Open Directory master to a stand-alone server and then repromote the server to a master or replica for testing purposes. If you do this, then Open Directory  cannot be set back up using The fix is to use Server Admin to repromote your server back to an Open Directory master and then use Server Admin to more graciously demote the server back to stand-alone. Until you do this, the will error out on Open Directory promotions that the server is already an Open Directory master. A change I’ve made to my workflow when nukin’ and pavin’ OD is to just use Server Admin for the paving part. If you demote with Server Admin you won’t have these issues. Hope this helps someone who finds similar wonkiness.

I’ve done a few articles over the years on customizing the team server in OS X Server. This is one of those places where Lion really changes things. Once upon a time you could just swap out the graphics and have a fairly custom-looking wiki or implementation. In Lion, Apple has really simplified and stripped down the Lion elements in the interface for the server. There is less Apple branding and more functionality than ever. Gone is the time Apple spent building templates, but in the place of all those templates is a much more integrated and functional collaboration server. Added are features dedicated to navigation (e.g. the ribbon was borrowed from MobileMe) document management and writing personal wiki articles. Added is a more seamless integration with podcasts and better ways to find content that is pertinent to you. Also added is a sidebar that allows you to insert blocks, similar to widgets in WordPress, but far less useable (for now). You can still customize the graphics. They are now stored in /usr/share/collabd/coreclient/public/stylesheets/cc/img. You can also add your own banner or edit the look and feel in the css files stored in the /usr/share/collabd/coreclient/public/stylesheets/cc. For example, editing the core.css file to change the color (not background-color) setting in the body section will change the color of the text (use my color chart to pick a new color if you’d like). Also in the core.css file is the background color for the unused space, located in the background-color setting of the main section. The blue title bar for wikis can also be customized to include a background image or just change the color. For example, use the banner.css file to add the background-color field into the banner section with #FFFFFF to set that to white. As usual, be careful when customizing Apple’s services. Personally, I find that whenever I customize their settings, I end up making them look worse. Apple is known for design. If you’re looking at my web site, you’ve likely noticed that I am not. If you decide to walk down this path though, I have a good tip. Use a browser plugin for Firefox to help you. You can make changes on the fly, see what works and what doesn’t and gradually change settings until you find a look and feel you can live with. I like Edit CSS, but as with many of these kinds of things, it’s just preference – search for CSS in the Firefox add-ons for one that you find that you like better.

Awhile back I did a little article on Bluetooth. I also did an article on disabling menu items such as Bluetooth, using Managed Preferences. But I hadn’t looked at granular controls of Bluetooth settings. Luckily, a user submission on the topic just came in and Ted Kidd from Michigan (thanks, Ted!). Ted has provided a script for disabling Bluetooth’s Discoverable mode. His submission:
I’ve found that more than a fair share of preferences are stored for each specific user on a computer. I’ve also found that some preferences are stored in a “ByHost” folder in /Users//Library/Preferences. Anything stored in the ByHost folder has the hardware UUID in the plist file name. /usr/sbin/system_profiler SPHardwareDataType | grep "Hardware UUID" | cut -c20-57 This line will pull the hardware UUID number so that it can be used in a defaults read/write script or something like that. You probably already know this, but it seems like a good tip to include on a website. I needed to do this to turn off “Discoverable” mode for bluetooth. defaults write /Users/<user>/Library/Preferences/ByHost/`/usr/sbin/system_profiler SPHardwareDataType | grep "Hardware UUID" | cut -c22-57` DiscoverableState -bool no launchctl unload /System/Library/LaunchDaemons/ launchctl load /System/Library/LaunchDaemons/ If using in a login script (via managed prefs), it would look like this: uuid=`/usr/sbin/system_profiler SPHardwareDataType | grep "Hardware UUID" | cut -c22-57` /usr/bin/defaults write /Users/$@/Library/Preferences/ByHost/$uuid DiscoverableState -bool no /usr/sbin/chown $@ /Users/$@/Library/Preferences/ByHost/$uuid.plist This script will turn discoverablestate to “off” and relaunch the bluetooth service.

Lion Server moves a few things around. Not only in regards to a little window dressing in the GUI apps, but also under the hood. One such example is the /ical extension often used to direct users to iCal’s little section of the web portal in OS X Server, no longer around in Lion. One could just redirect requests for /ical to /webcal as was done previously. But what if you wanted to actually redirect the CalDAV traffic to look at a directory other than /calendars on the web server (e.g. maybe your site already uses /calendars). To do so, check out /etc/apache2/servermgr_web_apache2_config.plist. About half way down are the proxies for Each of the directories has a path. I like to change both the name of the key and the string for the path. However, don’t change the urls key or the site will stop outputting dynamic data. Save the changes and then restart the service: serveradmin stop web; serveradmin start web /webcal is also defined here. So if you would prefer to use /ical then it can be changed, albeit likely breaking many of the internal links for the portal. One may be tempted to add /ical by adding an “Alias /ical /usr/share/webcal.html” line in the httpd.conf file in /etc/apache2, but that simply results in an error. So doing a redirect, as I showed previously seems to be the only way to get the response of the actual /webcal page (401 redirects do not seem to work). Another issue that I’ve run into is getting virtual hosts to work in the first place, in order to define non-page centric forwards. This was fixed by uncommenting the following line in the httpd.conf (removing the # in front of the line): Include /private/etc/apache2/extra/httpd-vhosts.conf Then, you can add vhosts as usual in /etc/apache2/extra/httpd-vhosts.conf. Having said that, the only redirect I’ve gotten to work so far have been per page. I’ll likely figure out more on these subtle changes as time goes on, but more important than these specifically, hopefully this will point others to where some of these settings are stored (e.g. for webmail and other services in OS X Server). For example, let’s say you wanted to disable the web calendar and webmail altogether (for whatever reason). In that case, look for these two lines in /etc/apache2/httpd.conf (respectively): Alias /webmail /usr/share/web/webmail.html Alias /webcal /usr/share/web/webcal.html Put a # in front of each to comment them out and then restarting the web service. It’s not pretty and webmail should be disabled in the Web service, but web calendars aren’t exposed in the GUI at this time and I wanted to show both. Anyway, this article is rambling on a bit like a Douglas Adams book. So, so long, and thanks for the phishing attacks!

LaunchPad is the OS X Lion version of the old Launcher, or the iOS home screen, according to how you look at these things. A few notes on issues I’ve seen with LaunchPad. First, I’ve had to nuke LaunchPad and have it rebuild. To do so, delete the database. rm ~/Library/Application Support/Dock/*.db You might also need to kill the dock: killall Dock In a deployment scenario, I’ve started doing both as post flight tasks. Getting to the point where you’re granularly adding and removing items is done by editing the .db file in ~/Library/Application Support/Dock. In here is a generatedID followed by .db that makes up a SQLite database. This database can be managed using a number of SQLite management tools, such as Base or SQLite Inspector. The management of databases from within these tools is pretty straight forward. You browse the apps, locate the offending rule and delete it. Then killall on the Dock (shown earlier) to actually have it disappear. You can also use the sqlite3 command line (where the string that begins with BF is the generated ID of the database): sqlite3 ~/Library/Application Support/Dock/BF222CEA-E6B2-4804-BAA2-DED0428E6C90.db "select * from apps" Assuming you see a row in the output that you’d just love to get rid of, you can look at the bundleID and then get rid of it using a command like this: sqlite3 ~/Library/Application Support/Dock/BF222CEA-E6B2-4804-BAA2-DED0428E6C90.db "DELETE from apps WHERE bundleid LIKE 'org.videolan.vlc'" Don’t forget to kill the Dock afterwards. That’s basically it. If you install an app and then want to toss items from Launchpad as a post flight use the bundleID, run sqlite3 and then a second query to verify that the item is gone. As you don’t know the generatedID for the database name, you can also replace it with * in scripts: sqlite3 ~/Library/Application Support/Dock/*.db "DELETE from apps WHERE bundleid LIKE ''" Oh, and the easy way to clean up LaunchPad is to use something like Launchpad Cleaner

When Lion was new, I put up a post about clearing out information on saved applications states. Saved application states are a new feature in Lion that remembers the screens that were open and where each was when you quit applications. The reason for that post was that those states were causing a few minor issues with applications. There are a few applications that the saving of application states is really awesome for. I think it will mostly be different for each persons workflow. Personally I like saving the state of Terminal, Safari and a few others. However, the state of some others can be a bit annoying for me. For example, Word. Luckily, you can control which applications have saved states and which do not. To do so, first find the application in ~/Library/Saved Application State. These usually are the bundleid of the application followed by .savedState. Using the bundleid (or whatever is listed if not the bundleid), you’ll then send a NSQuitAlwaysKeepWindows key to the defaults domain for that id with a boolean setting of true or false. For example, to disable the saved state for Microsoft Word: defaults write NSQuitAlwaysKeepsWindows -bool false To re-enable it, just send a true value into the same key: defaults write NSQuitAlwaysKeepsWindows -bool true
