The presentation this month will hopefully satisfy some curiosity and be a little bit of fun for everyone. It's one of those things you do because it looks interesting, but may not be of any real value to most members.

For fun, we'll be seeing how easy or difficult it is to set up an Internet broadcast stream using one of the several live Internet streaming services. In this case we anticipate we will be using the FREE streaming services of Ustream.TV. Another comparable alternative is

Initially, Peter was on the hook as the main presenter, but due to some technical shortcomings, John D will take the lead and possibly John M may become a supporting presenter.

Hopefully, with this presentation we will also get those of you with a broadband connection thinking about ways that you might want to use Internet TV for presentations to family, business, or the world. Know that every Internet TV broadcast by default can be seen by the world while "it is on the air", but knowing when & where to find it lends some very limited level of privacy to your broadcast.

Main Meeting Q&A: We began last month?s meeting with our normal round of questions and announcements. Among the questions and announcements:

Ed C -

John D -Rich T -John M -Layton F -Pat S -Don W -Peter W -Tom J -

Main Meeting Program: John D led the main presentation this month. The presentation focused on Windows File Sharing (WFS) on Vista and Windows 7 computers. Vista brought many GUI changes including additional security features over the old Windows XP OS. Some of these changes & features were tweaked and enhanced in Windows 7. So, we thought it was a long over due review of WFS on these newer OS's.

A rough collection of "show" notes can be found on the club's website at:

Apparently from some responses to the meeting there were a few new things learned and not all of them directly related to WFS.

Among some of the comments: * Learned how to put basic Windows Computer & Network & other icons on the desktop * Learned about the Windows Mobility Center for portable versions of Vista and Win7 and how to disabled the Wi-Fi radio completely. NOTE: The Wi-Fi radio interface can also be turned off thru Windows Device Manager, but this typically requires a re-boot, but is the only way to do it on desktop versions of the OS. * Learned about the Private (Home & Work) vs Public network security settings. NOTE: This was the primary impetus for this presentation. * Came away with an appreciation for the network reporting within the Belarc Advisor software.


This section contains web links & other info related to some of the subjects we discussed during our round table discussions and main presentation.

Lightworks - a nonlinear BETA software video editing system FREE for Windows. At the annual convention of the National Association of Broadcasters, NAB Show, on 11 April 2010, EditShare announced that they plan to transform Lightworks into Lightworks Open Source. It was presented at IBC in Amsterdam September 2010. On November 9th 2010, EditShare announced that Lightworks would be downloadable on November 29th of the same year, at first exclusively for the users who had registered during the initial announcement, but subsequently publishing the software as "public beta". Release of an Open Source version is planned in the middle of 2011, after code review has been finished. Money is to be made from proprietary plugins offered in an associated online shop, especially ones needed for access to video file formats used by professional cameras. Download: Info src:

Port Numbers - work like telephone extensions. Just as a business telephone switchboard can use a main phone number and assign each employee an extension number (like x100, x101, etc.), so a computer has a main address and a set of port numbers to handle incoming and outgoing connections.

WFS uses 2 basic ports, ports 139 & 445.

NetStat - is one of a number of command-line tools available to check the functioning of a network. It provides a way to check if various aspects (including PORTS) of TCP/IP are working and what connections are present. In Windows XP SP2, a new switch "-B" was added that allows the actual executable file that has opened a connection to be displayed. This newer capability provides a chance to catch malware that may be phoning home or using your computer in unwanted ways on the Internet.

TCPview - is a GUI frontend to the NetStat command and is from Microsoft's SysInternals group. TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, and XP, TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.

Belarc Advisor - (repeat from last month's newsletter) this FREE Windows software builds a detailed profile of your installed software and hardware, network inventory, missing Microsoft hotfixes, anti-virus status, security benchmarks, and displays the results in your Web browser.


Email Etiquette! REMINDER - We've covered this before. But, I think it needs to be repeated. When sending email, whether you're the originator, replier, or forwarder, ALMOST ALWAYS remove email addresses from the body of the email AND ALMOST ALWAYS use the BCC: field rather than the TO: or CC: fields for the recipients of the email when sending to multiple recipients, especially if the multiple recipients are strangers to each other.

Typical EXCEPTIONS to this rule might be when emailing within a business environment or emails originated by and sent among family members. ONLY leave email addresses within the body of the email if it is pertinent & of use to the context of the email.

WHY? To mitigate & minimize the potential for SPAM email OR WORSE, a potential break of personal security information by malware on a recipient's computer.
