A Treasure Trove of Technology Tidbits
I was recently installing the latest version of Red hat Linux in my virtual environment. When I ran through the installation, I noted that the installer did not automatically find the network adapter. Well, I thought to myself, that will get quickly resolved as soon as I install VMware tools. Since I had no network […]
Everyone knows they should be using ssh instead of telnet, and sftp instead of ftp. I regularly drop to the command line and use these utilities. By default, these run on port 22. But, sometimes you need to connect to a custom port number because the server is bound to something other than port 22. […]
Sometimes I need to get back to the basics to diagnose a problem. Although the telnet client is not a secure protocol, and you should be using secure shell (SSH) whenever possible, telnet is still useful when debugging SMTP issues. But, it’s missing from the default Windows 2008R2 installation. How do you install it? Do […]
I bounce between different operating systems and different network appliances all the time. As it happens, I sometimes type a Windows command into linux, or a redhat command into Cisco IOS, or even a Cisco command into Microsoft Windows (note: those are bad days). So, I created a little quick reference for the two things […]
We all need to communicate with each other. We coordinate schedules, we get in touch with relatives, we call stores before driving across town, and we check to see if folks needs anything from the store we happen to be standing in. One day I looked at my communications costs, including cellular and landline calls, […]
Sometimes webpages fail when they load. Sometimes the failure is minimal, like the new Delta Airlines website does not appreciate being asked to use larger font sizes. Sometimes its catastrophic. But, in any case, I find myself looking at the source code to figure out if it’s me, if it’s the browser, or if something […]
Normally, installing a virtual machine appliance is easy. Just download, deploy, answer a few basic questions, and the VMA is running. But, not today. Today, I went to install the newest SolarWinds VMA for Virtualization Management and promptly received the error “Cannot initialize property. ‘vamp.DNS0.SolarWindows_Virtualization_Manager’, since network has no associated IP pool configuration.” The first […]
I am in an out of customer sites all the time. I work in server rooms, in conference rooms, in offices, in cubes, and sometimes with my laptop propped on my knees. Mostly, I pack my Apple Air around with me, because closing its screen puts it immediately to sleep and it becomes portable. But, […]
Today, I installed another VMware vCenter server. This was not an unusual occurrence for me, as more and more companies are implementing server virtualization. But, today was unusual—the installation failed with the obscure error message of “Installation of VMware vCenter Server failed. Install VMware vCenter Server separately by using individual installer rather than WMware vCenter […]
So, VMware 5.0 has a new Consolidate menu item located in Inventory | Virtual Machine | Snapshot menu. What does it do? Before I get to that, let’s review what the other menu items do, because Consolidate only makes sense after you understand what can go wrong with snapshots. First, snapshots are a terrific feature.
