Replacing kernel-headers with custom compiled version (from kernel.org) - safe?
by Bagas Sanjaya 27 Jun '19

27 Jun '19

Hello CentOS users, Currently I have compiled kernel version 4.19.37, which the source is from kernel.org. I compiled the kernel by following steps: - get the kernel tarball and unpack it - install prerequisties as described in https://wiki.centos.org/HowTos/Custom_Kernel (in addition bc and openssl-devel) - copy the kernel configuration: $ cp /boot/config-3.10.0-957.21.3.el7.x86_64 ~/linux-4.19.37/.config - create configuration: $ cd ~/linux-4.19.37 $ make olddefconfig $ make nconfig - compile and create RPM package: $ make vmlinux $ make modules $ make rpm-pkg - install kernel RPM: # yum install ~/rpmbuild/RPMS/x86_64/kernel-*.rpm However, in the last step (installing kernel RPM), I got following notice: ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: kernel x86_64 4.19.37_sentinel_custom-1 /kernel-4.19.37_sentinel_custom-1.x86_64 209 M kernel-devel x86_64 4.19.37_sentinel_custom-1 /kernel-devel-4.19.37_sentinel_custom-1.x86_64 817 M kernel-headers x86_64 4.19.37_sentinel_custom-1 /kernel-headers-4.19.37_sentinel_custom-1.x86_64 4.6 M replacing kernel-headers.x86_64 3.10.0-957.21.3.el7 Transaction Summary ================================================================================ Install 3 Packages There, the compiled kernel-headers package (4.19.37_sentinel_custom-1) is about to replace stock version (3.10.0-957.21.3.el7). Is it safe to continue installing from compiled RPM package above, or install kernel manually? Regards, Bagas

Alternitives to Firefox...
by Robert Heller 27 Jun '19

27 Jun '19

OK, I recently ugraded to the current ESR release of Firefox for CentOS 6. And I am having problems with the user interface (basically it has become hard [for me] to use). What alternitives are there? (Chrome and Chromium are not possible with CentOS, and Chrome and Chromium are actually worse). -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller(a)deepsoft.com -- Webhosting Services

About PCYNLITX project and its innovations ( for C+++ multi-threading )
by Erkam Murat Bozkurt 27 Jun '19

27 Jun '19

Previously, I have presented my project to you. The current name of my project is PCYNLITX. PCYNLITX platform offers completely new programming technology which can be named as Programmable Meta-Programming System and PCYNLITX platform is just a particular application of this new programming methodology. Basically, PCYNLITX is an intelligent integrated development environment ( IDE ) which can produce an application-specific multi-threading library based on your needs and assists you in multi-thread software development process. PCYNLITX is not a multi-threading library. Instead, it is a multi-threading library generator. You can find out very comprehensive documentation about pcynlitx project from both project web site and source code repository. The addresses of the project web page and source code repository are given in below links. www.pcynlitx.tech https://sourceforge.net/projects/pcynlitx The outcome of the PCYNLITX platform acts as an autonomous thread management system provides deterministic scheduling of the threads. You can control the thread with the numbers given by you and determine the relation of the threads. In other words, different from the other multi-threading tools, you can directly schedule the threads independently from the operating system. The scientific journal of the project is under review on IEEE Transactions on Software Engineering. Currently, the PCYNLITX platform only works on Linux based operating systems and the other versions ( Windows and McOSx ) are under development. The License of the PCYNLITX platform is GNU GPLv3 Free Software License. You can find out many other documents including scientific introduction of the project (“Technical Introduction” ), code examples and GUI tutorial form the project web sites. You can also find out a documents introducing std::thread programming, pthread programming and OpenMP programming on the web sites. I am always waiting your valuable comments and contributions. Thanks and best regards. Erkam Murat Bozkurt M.Sc in Control Systems

Strange Network Bug Locks Up CentOS 7 Laptop
by Virgo, Paul E. (GSFC-610.2)[ADNET SYSTEMS INC] 25 Jun '19

25 Jun '19

All, I have a user who has a Dell Precision 7520 laptop, and we're running CentOS 7, latest kernel. This morning he had two lockup incidents. Nothing in /var/log/messages stands out so far, but did get this information when running 'abrt-cli list --since 1560891312': id c48278a875c27dd4369d971bcfc7db4267766c6d reason: WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:356 dev_watchdog+0x248/0x260 time: Thu 23 May 2019 07:12:57 PM EDT cmdline: BOOT_IMAGE=/vmlinuz-3.10.0-957.12.1.el7.x86_64 root=/dev/mapper/SysVG00-ROOT ro crashkernel=auto rd.lvm.lv=SysVG00/ROOT rd.luks.uuid=luks-29590e52-c08e-4c11-a784-cf2f3ffd98b2 rd.lvm.lv=SysVG00/SWAP rhgb quiet LANG=en_US.UTF-8 package: kernel uid: 0 (root) count: 4 Directory: /var/spool/abrt/oops-2019-05-23-19:12:57-28561-0 Reported: cannot be reported Has anyone seen this behavior before or this message?

Being as how we're looking at putting my SO on Linux (she's *so* fed up with Windoze), big question for her: Civ 6 on CentOS? Will it run on C 7? Wait for C 8 (which I was sort of thinking of doing, anyway)? mark

mplayer
by Chris Olson 25 Jun '19

25 Jun '19

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 mplayer. The repo update appears to be successful as indicated below. Dependency resolution at the time of mplayer installation yielded twelve errors. Are there other packages that could be installed prior to another attempt at mplayer installation that might provide the missing items? Might these errors have been avoided by choosing the multi media workstation install?

Disk Performance Issue
by Chris Olson 25 Jun '19

25 Jun '19

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 usual. Disk access, as indicated by the disk activity light, is almost continuous and for extended periods of time when ever something is done that requires the disk. Everything observed happens whether or not the machine is connected to our network. All of our files appear to be accessible if one is patient. One theory put forward is that some application is running that uses up CPU and disk bandwidth. Another theory is that thereare disk errors, mostly corrected by EDCS features. We do not see any rogue applications and error logs show no disk issues. This is a mysterious issue that we hope to circumvent by putting a new disk and installing CentOS 7 from DVD. Our hope is that the current disk can be mounted externally on the new CentOS system using a USB to SATA adapter and that data can be moved off of the old disk. Advice regarding this issue and any possible diagnostic methods will be greatly appreciated. df -k output: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_delle520-lv_root 51475068 12110896 36742732 25% / tmpfs 1928152 176 1927976 1% /dev/shm /dev/sda1 487652 211073 250979 46% /boot /dev/mapper/vg_delle520-lv_home 905124888 246856176 612284356 29% /home +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Issue with dvd/cdrom drive
by doug schmidt 24 Jun '19

24 Jun '19

Hi, I'm having an issue with my Thinkpad P70 laptop/workstation. This system is a dual boot, windows 10 pro and centos 7. I have not needed to use the cdrom until now, however the system does not see it in /dev. I know the cdrom works as I can use it in windows 10 and when initially installing centos 7, I installed from dvd media. I'm not sure what to check. I do not see anything related in dmesg. I have previous copies of kernel on the system and tried booting with 3.10.0-957.el7.x86_64 but I'm seeing the same. ---------- # uname -r 3.10.0-957.21.3.el7.x86_64 # lspci 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Host Bridge/DRAM Registers (rev 07) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor PCIe Controller (x16) (rev 07) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics P530 (rev 06) 00:14.0 USB controller: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller (rev 31) 00:14.2 Signal processing controller: Intel Corporation 100 Series/C230 Series Chipset Family Thermal Subsystem (rev 31) 00:16.0 Communication controller: Intel Corporation 100 Series/C230 Series Chipset Family MEI Controller #1 (rev 31) 00:16.3 Serial controller: Intel Corporation 100 Series/C230 Series Chipset Family KT Redirection (rev 31) 00:17.0 RAID bus controller: Intel Corporation SATA Controller [RAID mode] (rev 31) 00:1c.0 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #1 (rev f1) 00:1c.2 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #3 (rev f1) 00:1c.4 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #5 (rev f1) 00:1d.0 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #13 (rev f1) 00:1f.0 ISA bridge: Intel Corporation CM236 Chipset LPC/eSPI Controller (rev 31) 00:1f.2 Memory controller: Intel Corporation 100 Series/C230 Series Chipset Family Power Management Controller (rev 31) 00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31) 00:1f.4 SMBus: Intel Corporation 100 Series/C230 Series Chipset Family SMBus (rev 31) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-LM (rev 31) 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M600M] (rev a2) 04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) 05:00.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:00.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:01.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:02.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:04.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 07:00.0 System peripheral: Intel Corporation DSL6540 Thunderbolt 3 NHI [Alpine Ridge 4C 2015] (rev ff) 3b:00.0 USB controller: Intel Corporation DSL6540 USB 3.1 Controller [Alpine Ridge] 70:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.
