Any alternatives for the horrible reposync
by Dennis Jacobfeuerborn 28 Feb '18

28 Feb '18

Hi, I'm currently trying to mirror a couple of yum repositories and the only tool that seems to be available for this is reposync. Unfortunately reposync for some inexplicable reason seems to use the yum config of the local system as a basis for its work which makes no sense and creates all kinds of problems where cache directories and metadata gets mixed up. Are there any alternatives? Some repos support rsync but not all of them so I'm looking for something that works for all repos. Regards, Dennis

Everyone, Have any of you installed ubiguiti wireless routers on your network? It looks like the setup requires the use of software; they have some packages that are ready made for Ubuntu and Debian, but not RedHat https://www.ubnt.com/download/unifi/unifi-ap-ac-pro Have any of you tried or succeeded in installation this on Centos 7.4?

Cloud image_index: is 1801-01 a release?
by Nicholas Timkovich 26 Feb '18

26 Feb '18

I load CentOS cloud images into our infrastructure for our users to use, and I have a script that looks at https://cloud.centos.org/centos/7/images/image-index, picking what has the highest revision, to find the new hotness. Up until the most recent image, they've all appeared in there; is this changing going forward? How can I automatically find the newest one and its revision tag? The untagged "latest" ones (linked to by the https://wiki.centos.org/Download page) don't appear in the sha256sums file, so I couldn't even compare sums. Can I petition for keeping the cloud image-index up-to-date? -- Nick Timkovich | Software Engineer | Computation Institute, University of Chicago | npt(a)uchicago.edu

Re-enable grub boot in UEFI (Windows took over it)
by wwp 26 Feb '18

26 Feb '18

Hello there, Dell XPS-15-9560 laptop (SSD drive, UEFI, secure boot off).. Windows 10 pre-installed, CentOS7 installed in a separate partition and running for months w/o issue. Don't know what happened but at reboot yesterday (not even booted in Windows, just rebooted), grub has disappeared, booted in Windows by default, which apparently has taken over the UEFI boot. By booting from a USB drive w/ CentOS7 LiveGnome, I could use its grub command prompt to inspect the UEFI of the local SSD drive, see that the centos/ sub-directory and files are still there. /boot/efi/EFI/centos/: BOOT.CSV BOOTX64.CSV fonts grub.cfg grub.cfg.1501243846.rpmsave grub.cfg.1505469290.rpmsave grubenv grubx64.efi mmx64.efi shim.efi shimx64-centos.efi shimx64.efi maybe /boot/efi/EFI/Boot/ contents has been altered? /boot/efi/EFI/Boot/: bootx64.efi fbx64.efi I had a backup of the full efi partition (`dd`) but it's outdated and I feel it's a bad idea to restore the partition from it. Still from this "external" grub prompt, I could boot into my CentOS7 using: configfile (hd0,gpt1)/EFI/centos/grub.cfg At least I know how to get back to it :-). But now, how could I give the UEFI control back to grub? Is there a grub2 or grubby command I can run to make grub the default? I've read a lot and still cannot figure out exactly what to do or don't dare running commands that could make things worse. And I have the feeling the at next Windows boot, I may need to do it again.. Regards, -- wwp

Set LANG on CentOS 6 server
by Nicolas Kovacs 24 Feb '18

24 Feb '18

Hi, I'm having a weird problem on a CentOS 6 server. I installed the machine in french, so I have LANG=fr_FR.UTF8 defined. I'd like to define en_US.UTF8, because some output is better readable in english, like chkconfig --list. I replaced fr_FR.UTF8 in /etc/sysconfig/i18n and /boot/grub/grub.conf. Unfortunately, when I reboot the system, I still get this: # echo $LANG fr_FR.UTF-8 Any suggestions?
