Hello, I ran today update of my CentOS 6.9 running on Dell T105 (AMD OPTERON) and httpd failed to start. Any idea what could cause that? I never had a problem after CentOS 6.x update. Web server runs since March 2017. I do updates usually once in a week. Thank you Mikhail Utin

Hi folks. I?m looking for an email server. I have a C7 box already with nginx, PostgreSQL, Sinatra and Ruby. So I don?t want to install PHP, Apache, MySQL, etc. Are there any ways/tutorials to set up a mail server under those restrictions? It would serve multiple domains. Cheers, Bee

Hi, I installed CentOS 7.4 on a modern Lenovo ThinkSystem SR630 server which uses UEFI.

Hi, This question is not exactly CentOS-related strictly speaking, but here goes. I'm running a few newsletter servers for myself and a handful of clients on public CentOS servers with PHPList. For the last twenty years or so I've followed the basic rule that mails should have no formatting whatsoever, only simple text. And now I wonder if that basic rule of netiquette also applies to

...7% in most cases) of current CPU utilization. For instance, 100% utilization means 99.3% user software and 0.7% the hypervisor. You can use your system for years but will never notice that a hypervisor runs below your OS. It can come from anywhere and even from your motherboard firmware.

...d. I think it is pure marketing thing. people dump other stuff to remind you who they are and for a sort of entertaining us. The same story is in OS desktop GUI including Linux. I use CentOS 6 and 7 and still do not like 7. Not to mention in the morning Win 10 with all its crap included.

...our hypervisor identification software (HyperCatcher if you are interested) which is bootable image. However, I was unable to boot it until I disabled UEFI. As I understand it, it will block anything from booting excepting original OS. Your Xen and our HyperCatcher are outsiders for UEFI.

I'm having issues with a quad video card on CentOS. We have several systems on CentOS 6.8 and CentOS 6.9. The installed hardware is: Video card - Nvidia NVS quadro 440 PC - Dell OptiPlex 9020 Whenever you update the kernel, it kills the graphical interface.
