Asterisk kick start file for CentOS 5.5

Working with Asterisk a lot recently at work, I made this kickstart file for CentOS 5.5 32-bit to automatically install the OS, install Asterisk, update the OS, and reboot. Upon first boot you’ll have a fully up to date server with Asterisk already up and running with sample config files and a small selection of music on hold files installed. You’ll still need to add rules to  IPTables for sip ports 5060 and 5061. Get the kickstart file from Pastie here.

AFP – List of connected users & IPs

I was recently asked at work to write a small script that would restart AFP once a week. My boss wanted to get an e-mail with a list of the currently logged in users to AFP along with their respective IP addresses. This is a messy one liner to get most of the information, but it gets the job done:

sudo serveradmin command afp:command = getConnectedUsers | egrep '(ipAddress)|(name)' | sed '$!N;s/\n/ /' | cut -d '"' -f 2,4 | tr '"' '\t'

Here’s the full script: (more…)

Apple – iPhone 4 Press Conference Fri

Engadget and others are reporting Apple will be holding a press conference on their corporate campus this Friday, July 16, at 10 AM pacific time to discuss iPhone 4.  No other details were given.

This should be interesting.

Consumer Reports on iPhone 4

It’s official. Consumer Reports’ engineers have just completed testing the iPhone 4, and have confirmed that there is a problem with its reception. When your finger or hand touches a spot on the phone’s lower left side—an easy thing, especially for lefties—the signal can significantly degrade enough to cause you to lose your connection altogether if you’re in an area with a weak signal. Due to this problem, we can’t recommend the iPhone 4.

Thoughts on iPhone 4

I’d like to preface my post with a small description of what I do for a living, alongside being a full-time student at Robert Morris University (RMU) in Pittsburgh, PA.  Freshman year through senior year of high school at Fox Chapel Area High School, I worked as a student employee alongside the network and systems administrator and help desk staff to provide end-user support and training to teachers, administrators, faculty, and staff.  I continue to work there today providing the same services as before, but I also am now more involved in assisting the network and systems administrator with more complex projects.  Fox Chapel has over 40 Xserves and 5,000 Macs in the district.  I also work at Robert Morris University as an IT Student Associate Systems Administrator supporting Mac OS X and Mac OS X Server.  I manage most of the Macs on campus, most of the Xserves, and OS X deployments and the associated network services that go along with the authentication and collaboration of the Mac users.  In a nutshell: I know Macs and Mac OS X pretty darned well, Mac OS X Server decently well, and I absolutely love Apple and its products.  Why did I mention all of that?  I’m not usually one to complain about Apple.  I’m not just the normal flamer who’s overreacting about the issues with the iPhone 4.  And, when issues arise, I’ve always trusted and will continue to trust Apple to make those issues right for its customers.  That all having been said, here’s my thoughts on iPhone 4.

WWDC 2010 Keynote Predictions

Tomorrow at 10 AM Pacific Time, 1 PM Eastern Time, Apple CEO Steve Jobs will take the stage at the Moscone West conference center in San Francisco CA to kick off Apple’s Worldwide Developers Conference 2010 (WWDC 2010).  The keynote isn’t a general media event just to launch new products.  The entire conference is for developers to interact with one another and Apple engineers to learn more about developing for the Mac and iPhone OS platforms.  There’s workshops, lectures, and a whole host of other things going on at the week long conference.  However, one of my best friends, Kyle Van Essen, is attending and is representing his company Vibealicious along with his coworker and friend, Joel Levin.

Even though the keynote isn’t mainly focused on releasing new products, Apple generally uses WWDC to announce a few things.  Here’s what I think we’ll see tomorrow: (more…)

Twitter Announces Ad Platform… Or Not

Today at SXSW, Twitter co-founder Ev Williams was rumored to finally be announcing an ad platform and/or future business model for Twitter.  Instead, he threw the audience for a loop and announced a new platform called @Anywhere.  @Anywhere will allow website administrators to add better Twitter integration into their sites.  Essentially, anywhere there is a Twitter username, if a user hovers his mouse over it, he’ll see a mini “hovercard” containing the user’s Twitter information, including the most recent tweet.  Publishers will be able to integrate their own Twitter profiles in a more effective manner, making it easier for their readers to follow them.  Implementation will only take a few lines of javascript, and on launch Twitter already has partners such as the Huffington Post, New York Times, Meebo, Amazon, Yahoo, eBay, and Bing.

You can read more about it on the Twitter blog.

So when will Twitter be announcing a future business model and/or advertising platform?  For now, according to Mashable, “Williams says Twitter is still mainly focused on creating the best experience for users and businesses.”

Guide: Using Mac OS X Server as a PDC

Mac OS X Server can act as an NT-Style Primary Domain Controller through the use of Samba (SMB).  The Mac OS X Server can provide file and print services as well as host user profiles and home folders and provide authentication services for the domain.  Even complex user and group policies can be implemented through the use of a logon script.  Again, all of this is accomplished through OS X Server’s implementation of the open-source Samba package which is a free software re-implementation of the SMB networking protocol.  Please note this guide focuses on Mac OS X Server 10.6 and Windows XP Pro SP3 clients.  Vista clients (Edit: Windows 7 clients are not supported. See this article.) should work equally as well with a few tweaks (outlined later). (more…)
