Find and set your optimal MTU setting to improve your connectivity

MTU Ping Test

Want to determine the optimal MTU for your ISP connection?

  1. Go to Search or Run (Windows 7 vs. XP)
  2. Type in cmd. Hit the enter. A Command prompt window will open.
  3. Type ping -f -l 1500 and hit Enter (or a website of your choice).

  1. Look at your results.  Does the packet need to be fragmented?  Try lowering the size of the packet in increments of 8 to 10) until you have a packet size that does not fragment.

  1. Once the packets are not fragmented, begin increasing the packet size from the number you find in small increments until you find the largest size that does not fragment.  You will need to add 28 to that number  for IP/ICMP headers to get the optimal MTU setting.
  2. If you get 1410 as the largest packet size, add 28 to that number and 1438 would be your optimal MTU setting.
  3. To change the number, use TCP Optimizer.

Remember to change all computers on the network including the router’s MTU setting.

NTCore has an excellent little program that will patch .exe files of applications letting them use 4gb of RAM. Typically these applications will use far less than the 4gb of RAM in a 32bit operating system.  This 4GB Patch file is a tiny file that modifies the executable of files and creates a backup of the file.  Once executed, you simply pick the .exe file and it will patch the file to use more memory.

The software will then ask if you have finished or if you need to patch another file.

If this does not work, simply delete the new .exe and rename the backup file back to the original name.

Innovation and leadership in IT at the Tennessee Technology Center at Shelbyville

The IT team at TTC Shelbyville  offers innovation and leadership recognized nationally in magazines1 and in education.    Under Ivan Jones, Director of the educational facility, the team consist of three personnel who teach and also maintain a complex and diverse network.

The Computer Information Technology class in Shelbyville offers more certifications than any other institution’s program in Tennessee.     Beginning as a simplex class in the mid ’90s, the program evolved from a small PC Repair class to one of the most comprehensive classes in the nation.   The CIT program offers a curriculum that exceeds state level CIT standard curriculum.

So what is unique about the Tennessee Technology Center at Shelbyville’s CIT Program?    The program not only offers 30 hours per week of hands-on along with traditional classroom training but also  offers over 2000 resources in an LMS that is available 24/7/365.

With resources that include PowerPoints, movies, study materials, software and other traditional e-learning resources, the class also offers a lab in the cloud.  Unlike any other class, the lab isn’t software simulators but it is physical switches, wireless, routers, virtualization, firewalls, hubs, servers, cameras and other hardware.

The LMS has been programmed to not only be used by standard laptops and computers but can be used on smartphones and tablets regardless of the vendor.

“Students couldn’t take home managed switches, firewalls, routers, access points and other hardware – so we put the hardware where they could use it – anywhere in the world.”, stated Mallard. 

Real hardware in the cloud has been expanded to include SCADA devices and controls in the cloud.

The recent success of the learning management system was recognized by Computerworld and Techtarget.  TTC’s LMS also offers live video broadcast that has been used to deliver video conferencing and educational classes to other states.  With more than 100,000 logins last year, the institution’s Computer Information Technology LMS server will be upgraded the last quarter of 2012.

While a traditional student may receive a little over 500 hours in the classroom along with labs in college or universities in their area of study, the CIT program’s students receive 2196 hours of instruction, hands-on in labs and now at TTC Shelbyville students receive real world hands-on working with local non-profits and government entities.

Because of technological advancements,  students have to learn more information and technology at an accelerated pace.   Waiting four years to enter a career, technology will leave skills and technology learned behind for traditional students.

Working with national certification entities such as CompTIA, CWNP, ECCouncil and Microsoft, a CIT student’s work is measured by hands-on, academic achievement, industry certifications and other performance metrics.   Students are encouraged to start their careers immediately, continue advanced certifications and to enroll in college in order to complete a well rounded career path.
