Opportunistic TLS

We had to upgrade our mail gateway/anti-spam software on Sunday because one of our vendors requires us to use encryption when exchanging emails with them.  The easiest solution is to use opportunistic TLS, where the server will always try to connect to the other server using the TLS protocol.  If the other server supports TLS, then traffic is encrypted.  If not, then the email is sent using just regular SMTP without encryption.

This is actually the first time I’ve even heard of opportunistic TLS, I’m used to seeing S/MIME and PGP when reading about email encryption.  What I like about this is encryption/decryption is done on the server side so the users don’t have to do anything different when sending emails and we don’t have to issue a certificate to each user and manage the keys.

If you’re using Exchange Server 2007, opportunistic TLS is already enabled by default.  You can check this by entering Get-SendConnector “Send Connector Name” | Format-List in the Exchange Management Shell.  Look for the IgnoreStartTLS parameter, if it’s set to false then opportunistic TLS is enabled.

To check whether a server supports TLS, telnet to the server on port 25 and check if the server supports the STARTTLS command, for example:

telnet mail.global.frontbridge.com 25

This server supports TLS

Here’s an example of the header of an email that was delivered with TLS enabled (I modified the IP addresses and names for privacy reasons):

Received: from mailgateway01 (1.2.3.4) by mailserver01.domain.com (1.2.3.5)
with Microsoft SMTP Server (TLS) id 8.1.263.0; Mon, 16 Mar 2009 18:05:18
-0400
Received: from mail.global.frontbridge.com ([65.55.88.22]) by mail.somedomain.com

TLSv1/SSLv3,128bits,AES128-SHA) id 06456c96000057da for <jdoe@microsoft.com>;

RSA SecurID 3.0.2 for BlackBerry

My colleague informed me earlier that RSA just released this new version of their SecurID software for BlackBerry sometime last month.  I installed it right away on my BlackBerry 8330 with OS v4.5.0.131 and it finally worked!!!  I’ve been trying to get their software to work on my BlackBerry since last year but my OS wasn’t supported.

This new version also now supports RIM OS version 4.7, so if you have a BlackBerry Storm this should work.

You can download the software from here: http://www.rsa.com/node.aspx?id=1165

How to automate Microsoft Office 2007 installation

I was just updating some documentation on our wiki and found some old notes on automating Office 2007 installation.  We upgraded our Microsoft Office software early last year from Office 2003 (and a few Office XP) to Office 2007 and this simple installation script saved us a lot of time. Here are the steps:

Step 1.  Copy the contents of the Office 2007 installation CD (or package) to a network share (eg. \\server\Office12).

Step 2.  Run the Office Customization Tool and create a setup customization file (I got these instructions from a BDD 2007 document on Microsoft’s website).

Desktop, Network, and Windows skills in demand?

Desktop support ranked as the most wanted skill sets for 76% of CIOs, with network and Windows administration taking the second and third slots with 65% and 64%, respectively. Database management is considered hot for 55% of respondents, and telecommunications support and wireless network management was selected by 47% and 46% of CIOs polled, respectively. Rounding out those skills seen as in demand are Web development/Web site design (39%), virtualization (35%) and business intelligence (31%).

Full Article

The study is based on data gathered from about 300 clients with $200 million or more in revenue, according to Network World.

I’m actually a bit surprised with the findings.  I didn’t expect desktop support to be the most wanted skill, I was expecting virtualization to be at the top because of all the cost/time savings virtualization can provide.

100,000 Miles!

100,000 Miles!

I was driving to work this morning and noticed my car just reached 100,000 miles!  I pulled out my BlackBerry and took a quick picture at the next stop light.  The picture is really blurry though.

Hoping to get another 100,000 miles from this car!

Tweet from your BlackBerry

Tiny Twitter

If you’re looking for a Twitter application for your BlackBerry, I recommend that you give Tiny Twitter a try.  It has a nice user interface, plenty of options, and supports keyboard shortcuts.

This is the first mobile Twitter application that I’ve tried and I’m not really planning on trying the other ones out there because I’m happy with this one already.  It does pretty much all the Twitter-related functions that I need, but I’m still pretty new to Twitter so I’m not sure if this is good enough for the heavy Twitter users.

Here are some of the options that are available: Update, Tweet, Access Links, Reply, Direct, Retweet, User Timeline, Unfollow, Delete, Inbox, Nearby Twitter Peeps, What’s Hot, Search, Hide Friends.

Happy Tweeting!

Twitter

I just created a Twitter account.  I’ve been seeing a lot of articles about it lately so I decided to finally give it a try.  I’m still not sure whether I’m gonna keep using it, but so far I’m liking it a lot.  Very simple and easy to use and it looks like it will be a good complement to my blog.

The first thing that actually came to mind when I signed up for an account was how to integrate it with my blog.  I found a WordPress plugin called “Twitter Tools” and installed it right away.  It seems to work pretty well, you can also use it to post a “tweet” directly from your WordPress blog and you can even set it to notify Twitter every time you write a new post.

You can view my latest tweets on the sidebar on the right.

Score with Virtualization

We just got back from the Citrix virtualization seminar in Washington D.C.  The seminar was very informative with live demos of their products.  They pretty much covered all their virtualization products and how they work together: XenApp (application virtualization), XenDesktop (desktop virtualization), and XenServer (server virtualization).  They also had three of their customers come in to share their experiences with Citrix virtualization technologies.

Now for the free stuff.  Attendees received a small bag (man purse?), a notepad, a pen, and a 1GB flash drive.  Citrix XenServer is also now free with XenMotion (live migration) and XenCenter (let’s see how VMware responds to this ).  Picture of the free stuff below.

Occasional Teleworkers On the Rise

Working from home is an increasingly popular option for U.S. employees - at least occasionally.

The number of U.S. employees, contractors and business owners who worked remotely at least one day per month increased 17% in the past two years, from approximately 28.7 million in 2006 to 33.7 million in 2008, according to global HR association WorldatWork. In the five-year period since 2003, the total number of once-a-month telecommuters in the U.S. has risen 43%.
