My thanks to all that responded to my posting about our virtual machine CentOS 6 system start-up issue.? I found the alternative boot options to be the most helpful.? Interrupting the boot-up process with Alt-d or Escape allowed me to see what appears to be a quite normal string of start, install and mount activity. However, this process ends with the system hanging at the point below: Starting

I installed CentOS 7 from the DVD iso file: CentOS-7-x86_64-DVD-1503-01.iso Yum update was used (with no update issues) to install and update many packages. The installer is significantly different from CentOS 6 where one can basicallychoose to "install everything" if one has the patience to check all productsand all software options within those categories.? During the CentOS 7

Recent power management discussions plugged into one of our current frustrations, namely the interaction of the screen lock and power-save features on Intel/CentOS 6 platforms. We certainly would not have guessed that locking the screen would inhibit going into the power-save mode, but it sure seems to do exactly that on some of our test platforms. If one leaves the desktop idle for the timeout

There has been a bit of grumbling recently about HP printer capability in one of our smallest prototyping Labs.? We have a single GigE switch connecting a Windows 7 machine and a Dell/CentOS-6 machine.? The CentOS machine also has connectivity via another network.? Currently, only the Windows 7 machine has been setup for printing on our HP OfficeJet 8615. Our Samba effort on the CentOS system has

We have several CentOS 6 systems that are used in various configurations of test equipment.? One of the primary functions of these systems is the connectivity to serial ports of some operational systems that have serial port control requirements.? Lack of interface bus slots led us to the use of USB connected serial ports on these CentOS 6 systems. We first used these USB connected serial ports

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services.? This begged a question about why every computer would not have a radio module to receive time.? Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned

We have been fortunate to hang onto one of our summer interns for part time work on weekends during the current school year. One of the intern's jobs is to load documents and data which are then processed.? The documents are .txt, .docx, and .pdf files. The data files are raw sensor outputs usually captured using ADCs mostly with eight bit precision.? All files are loaded or moved from one

How does the latest Intel flaw relate to CentOS 6.x systems that run under VirtualBox hosted on Windows 7 computers? Given the virtual machine degree of separation from the hardware, can this issue actually be detected and exploited in the operating systems that run virtually?? If there is a slow down associated with the fix, how much might it impact the virtual systems?

We have been following the email list discussion regarding recent problems with yum and the upgrade to the most current CentOS 7. We have also tried some of the remedies suggested or recommended. None of these measures has yielded success, and it is not totally clear whether or not our most recent yum issues have the same root cause as those experienced by others. Fortunately, our yum execution

We have recently been asked to evaluate some computing machinery for a new project. This particular end user has very limited experience with the stated security requirements in a lights-out environment. Their primary work (as well as mine) in the past has been with very small, simple networks of desktop machines and a few servers with extremely limited access.? For the most part, their admins
