Unigroup's March 2013 meeting will continue on our Post-SuperStorm Sandy theme, and will be on Remote Access / Remote Desktop.

At past meetings, we have discussed VNC / Virtual Network Computing and its use for Remote KVM (Keyboard/Video/Mouse) / Remote Desktop. NX is another alternative, which makes use of the existing X11 stack found on most Unix/Linux/BSD graphical systems.

We are also planning a future talk on Failover+Multipath Network Routing, which should happen given speaker availability.

We are also working on a Field-Trip meeting on Data Centers, to hopefully include a Data Center Tour. We are currently working with a local Datacenter Vendor, to hopefully hold this meeting in the upcoming months. This meeting may happen on a non-3rd Thursday too, so keep an eye out for it.


   Most Unigroup meetings are open to the public!

   To REGISTER for this event, please RSVP by using the
       Unigroup Registration Page.

   This will allow us to automate the registration process.
   (Registration will also add you to our mailing list.)
   Please avoid emailed RSVPs.

   Please continue to check the Unigroup web site and THIS page,
   for any last minute updates concerning this meeting.  If you
   registered for this meeting, please check your email for any last
   minute announcements as the meeting approaches.  Also make sure
   any anti-spam white-lists are updated to _ALLOW_ Unigroup traffic!
   If you block Unigroup Emails, your address will be dropped from
   our mailing list.

   Also, if you have an interest in Unigroup, be sure to receive
   Unigroup information DIRECTLY from Unigroup, via direct receipt
   of Emails and by visiting the Unigroup Web Site.  NO OTHER SOURCE
   provides timely, accurate and complete Unigroup information.

   Please RSVP as soon as possible, preferably at least 2-3 days
   prior to the meeting date, so we can plan the food order.
   RSVP deadline is usually the night before the meeting day.

   Note: RSVP is requested for this location to make sure the guard
         will let you into the building.  RSVP also helps us to
         properly plan the meeting (food, drinks, handouts,
         seating, etc.) and speed up your sign-in at the meeting.
         If you forget to RSVP prior to the meeting day, you may
         still be able to show up and attend our meeting, however,
         we cannot guarantee what building security will do if
         you are "not on the list".

Topic: Linux Remote Desktop Access using NoMachine NX

Introduction & Description of Talk:

NX provides Remote Desktop access for Linux with the same performance as Windows Remote Desktop Client. All of the encryption used with NX may be provided with OpenSSH. NX compression reduces X11 latency and traffic, and adapts bandwith usage depending on network conditions.

Robin Polak (http://robinpolak.com)

Robin Polak began his career in the academic field for 10 years, entering into IT as a Network Technician where he maintained the cabling plant for Manhattan College. From there he progressed into overseeing the network operations for two campuses as Manhattan College and the College of Mount Saint Vincent joined forces. Upon the dissolution of the joint department at which point the colleges became once again separate entities he took on the role of Network Manager at the College of Mount Saint Vincent. Since then, he has entered the world of High Frequency Trading with his current employer Lime Brokerage. Here he is part of a well oiled team which supports the day to day data center operations as well as supporting the staff at the NYC-based business office. Through this journey in IT, he has grown as a capable Linux Administrator and honed his skills in managing complex network environments. His preference lies in Linux Administration. He really enjoys working with free and open source software to craft enterprise class solutions to business needs. In addition to working with the software, he also enjoys taking part in the community through attending and contributing to user groups such as Unigroup, NYCBUG, and NYLUG to name a few. Like many IT workers, he also has had the pleasure of becoming intimately familiar with Microsoft Corporation's product offerings as well, including MS-Exchange, MS-Office, as well as their wide variety of Windows flavors. Robin is a Unigroup member, and also serves on Unigroup's Board of Directors.




Addison-Wesley Professional/Prentice Hall PTR, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.

Unigroup would like to thank both companies for the support provided by their User Group programs.

As always, all of the books will be available for review at the start of the meeting.


Unigroup is a Professional Technical Organization and User Group, and its members pay a yearly membership fee. For Unigroup members, there is usually no additional charges (ie. no meeting fees) during their membership year. Non-members who wish to attend Unigroup meetings are usually required to pay a "Single Meeting Fee".

         Yearly Membership (includes all meetings):      $ 50.00
         Student Yearly Membership (with current! ID):   $ 25.00
         Non-Member Single Meeting:                      $ 20.00
         Non-Member Student Single Meeting (with! ID):   $  5.00

       * Payment Methods: Cash, Check, American Express.

       ! Students: We are looking for proof that you are
         currently enrolled in classes (rather than working
         full-time), and as such, your Student ID should show
         a CURRENT date.  We have been presented Student IDs
         containing NO dates whatsoever, and in the
         current environment, perpetual/non-expiring access
         to university facilities just does not feel right.
         If your ID contains no date, please bring
         additional proof of current enrollment.  Thanks.

NOTE: Simply receiving Unigroup Email Announcements does NOT indicate membership in Unigroup.

Members: Remember to bring your membership card with you to the meeting, to confirm your yearly renewal date!


Complimentary Food and Refreshments will be served. This includes "wraps" such as turkey, roast beef, chicken, tuna and grilled vegetables as well as assorted salads (potato, tossed, pasta, etc), cookies, brownies, bottled water and assorted beverages.

However, our long-time cateror is no longer in business so the food service will be changing! We may have Pizza and Soft-Drinks at this meeting instead of the catered food.

Please join us for this meeting, you won't want to miss it!
