Power Management
I assume you have double-checked Gnome's power management preferences and they are what you'd expect, right? -- Sent from the Delta quadrant using Borg technology!

HP OfficeJet Printing
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

System Start-Up Issue Progress
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

root .bash_profile?
Ah thank you. Having forgotten this, I already had all my aliases and instructions in there. For some reason they aren?t loading. If I do this, then everything loads: source /root/.bash_profile So there?s an indication this isn?t loading upon entry into su. Is this normal? > On May 13, 2019, at 8:38 AM, Nux! <nux at li.nux.ro> wrote: > > Hi, > > The $home of root

System Time Source
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

CentOS 7 Gnome
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

Power Fail Protection Update
Many thanks to those that responded to my original posting with information about Network UPS Tools and commercial UPS products. In our planning a path forward to implement UPS-based power fail protection, we have come across what appears to be an issue with the state of the CentOS 6 machines being UPS protected.? Most of these machines are desktop/deskside machines that are likely to be idle

USB Serial Ports
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

Gulliver
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

[PATCH] p2v: Inhibit power saving during the conversion.
We do this by sending an Inhibit() message to logind and receiving a file descriptor back, which we hold open until the conversion completes (or fails). This is described here: https://www.freedesktop.org/wiki/Software/systemd/inhibit/ This adds an additional optional dependency on DBus since we use DBus to call the Inhibit() method.

Intel Flaw
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?

mplayer
We recently installed CentOS 7 from DVD.? Our install selection was the GNOME desktop option. yum update yielded about 465 megabytes of updates all of which were successful with no warnings.? The multi media option was not chosen because KDE was listed. GNOME was not apparent in the software list for the multi media workstation install. Google searches led us to instructions for installing

Shut down DN2820FYKH with power button
Hello. I've installed CentOS6.5 x86_64 on DN2820FYKH. I want to shut down with power button. But, the acpid daemon cannot work correctly. And, after I selected grub menu, the error message "ACPI: Unable to load the System Description Tables" is displayed. Does this message relate to the issue? I've checked, but the issue doesn't solve: *BIOS update ==> BIOS ver.0028 to

CentOS 7 turn off power saving by command line
In CentOS 6 gconftool-2 (command line) is used to enable/disable items. In CentOS 7 I found "settings->power-> blank screen" as something I wish to configure by the command line? How is that accomplished? I brought up gconf-editor and searched for power and blank and found nothing. How can I control this setting from the command line? Thanks Jerry

Disk Performance Issue
We have a very old Dell desk top machine that has been running CentOS 6 for the past five years.? It received a new, 1 TB disk and additional memory before the OS installation.? It has been the primary Linux machine in our smallest and most remote field office.? It has been updated at least once a week and has all current dates installed. Boot-up this morning lasted about six times as long as

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

CentOS 7 yum Issue
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
