The below article is the first in a series of articles to help get you more familiar with the BigIP BigPipe commands used to manage an LTM VE or Local Traffic Manager Virtual Edition installed in VMWare Player as noted in this article. After following the steps in this article you will have created two VLAN’s (Virtual Local Area Networks) and added an IP address to each VLAN which will be the foundation of the series of articles that will help you setup and configure your LTM VE to do basic load balancing followed by other articles that build on that foundation. The future articles will become more in depth by first taking you through basic troubleshooting steps using and overtime using more advanced techniques for troubleshooting issues on a BigIP Local Traffic Manager.
Earlier tonight while working on a Windows 7 Ultimate server I needed to reboot the computer to complete some changes made on the server but the Restart/Shutdown capabilities are removed from the start menu for security reasons. Luckily you can still easily reboot Windows 7 remotely when connected via Remote Desktop using the instructions below.
A couple days ago I was working on the network at the computer shop and ran into an issue configuring the Cisco Catalyst 2950 switch we have on part of the network. The goal was to set up three VLAN’s to segregate traffic on three segments of the network that each have their own purpose. One of the VLAN’s is used by the employees, one VLAN used for the public, and the third VLAN used to host servers that provide various services. I was in a rush to minimize downtime when I was configuring the access to the 2950 switch itself and attempted to assign an IP address to two of the VLAN’s. Below I explain the details of the issue that caused as well as an explanation of why this won’t work.
I was troubleshooting a Windows XP computer that had been brought in to my friends computer shop this afternoon and noticed something odd going on with the Windows Task Manager. The computer had multiple issues including various viruses, Norton Internet Security installed, hadn’t been upgraded or patched for over a year, and numerous other items going wrong. I will say that Norton Internet Security is probably the worst antivirus software I have ever come across because not only does it take over every aspect of your computer but on top of that it doesn’t even save your computer from getting infected by viruses. After getting the computer in working shape by removing Norton Internet Security and beginning the installation of Windows XP patches I launched Windows Task Manager to view something and when I did the list of running applications displayed but I could not click other tabs that normally appear at the top of the Task Manager. Below I display an image of what the Windows Task Manager looked like and how I easily resolved the issue.
I recently installed Windows Virtual PC on my Windows 7 laptop and so far really like using it for virtual machines. One thing that I needed to change after the initial installation was to assign more available memory to the virtual machine which I initially thought I could do from within the XP Mode virtual machine as displayed in the below image.
