Issue with latest update of CentOS6
by Walter H. 11 Oct '18

11 Oct '18

Hello, after I did update all my CentOS6 boxes - VMs and router; two of them (one VM and the router) are my local DNS resolvers; and I'm using the DNSSECTLSAvalidator plugin from nic.cz: https://www.dnssec-validator.cz/ before the update this plugin worked using my resolvers, after the update I get: "Failure - bogus DNSSEC reply, DNSSEC validation not possible with current settings" of course, when telling using a custom resolver (the one of nic.cz) it works, but before mine worked, too ... Thanks, Walter

I need SERIOUS help on GRUB in CentOS 7.5 1804
by Turritopsis Dohrnii Teo En Ming 11 Oct '18

11 Oct '18

Good afternoon from Singapore, I need SERIOUS help on GRUB in CentOS 7.5 1804. Please refer to my installation notes at http://lists.linuxfromscratch.org/pipermail/lfs-chat/2018-October/028964.ht… According to Petros' instructions, I need GRUB Legacy 0.97 for my Extremely Simple Linux. But GRUB Legacy 0.97 has been deprecated in CentOS 7.5. GRUB2 is installed by default on CentOS 7.5. So I defied Petros' instructions and used GRUB2 for my Extremely Simple Linux compilation, with the end result that I do not see any operating system selection menu on GRUB2. What I get is a grub prompt and I need to enter the following GRUB2 commands: grub> linux /boot/vmlinuz-4.18.12 root=/dev/sda1 ro quiet grub> boot (1) If I seriously want to use GRUB2 for my Extremely Simple Linux, I would need to modify /boot/grub/grub.cfg to suit GRUB2. Because Petros' /boot/grub/grub.cfg is meant for GRUB Legacy. Am I right? I am no expert on GRUB. (2) If I want to use GRUB Legacy for my Extremely Simple Linux, I would need to use CentOS 6 instead of CentOS 7? (3) If I insist on using CentOS 7.5, is there any way of getting rid of GRUB2 and installing GRUB Legacy instead? If you watch my short 2-min YouTube video at https://www.youtube.com/watch?v=YrJADssqaQU , I am not getting any operating system selection menu on GRUB2. I am getting a grub> prompt only. Please advise. Thank you. ===BEGIN SIGNATURE=== Turritopsis Dohrnii Teo En Ming's Academic Qualifications as at 30 Oct 2017 [1] https://tdtemcerts.wordpress.com/ [2] http://tdtemcerts.blogspot.sg/ [3] https://www.scribd.com/user/270125049/Teo-En-Ming ===END SIGNATURE===

Gutenprint - Gimp - Color pcl files
by Gregory P. Ennis 10 Oct '18

10 Oct '18

Everyone, I am trying to create a 'color' *.pcl from a pdf file with the use of gimp and the gutenprint gimp plugin. I have done this easily to create a black & white *.pcl file, but have not found a way to create a file that contains the 'color' commands for an HP laser printer. I am running Centos 7.5 with all of the latest updates. gutenprint- 5.2.9-18.el7.x86_64 is the current version in the Centos repositories While using the gutenprint plugin within gimp I am allowed to select from a list of HP color printers : HP Color LaserJet 2500 HP Color LaserJet 4500 HP Color LaserJet 4550 HP Color LaserJet 4600 HP Color LaserJet 5 HP Color LaserJet 5000 HP Color LaserJet 5500 HP Color LaserJet 8550GM But when I use any of these I am not allowed to select 'Color' on the output tab. I have tried to use other drivers like 'HP DesignJet 450C' and am able to select color options without a problem and to produce a color *.pcl file, but the file created obviously does not work on a hp color laser printer. I tried installing gutenprint 5.3.1 from https://sourceforge.net/projec ts/gimp-print/files/gutenprint-5.3/5.3.1/ , and things seem to go well, but I have little experience with the process, and after the installation and reboot there were no differences with the use of the HP Color LaserJet drivers. I would like to be able to create a color *.pcl file for an HP Laser printer; if any of you have suggestions as to how to do this with gimp or even cups I would sure appreciate your help. -- Greg Ennis

Are these instructions meant to be executed on CentOS 1804?
by Turritopsis Dohrnii Teo En Ming 08 Oct '18

08 Oct '18

Good afternoon from Singapore, I came across this Linux Journal article titled "DIY: Build a Custom Minimal Linux Distribution from Source", written by Petros Koutoupis. Link: <https://www.linuxjournal.com/content/diy-build-custom-minimal-linux-distrib…> https://www.linuxjournal.com/content/diy-build-custom-minimal-linux-distrib… Are the instructions in this article meant to be executed with ease on CentOS 1804 or perhaps easier on other Linux distros? Please advise. Thank you. ===BEGIN SIGNATURE=== Blogs: Turritopsis Dohrnii Teo En Ming's Academic Qualifications as at 30 Oct 2017 [1] https://tdtemcerts.wordpress.com/ <https://tdtemcerts.wordpress.com/>[2] http://tdtemcerts.blogspot.sg/ <http://tdtemcerts.blogspot.sg/>[3] https://www.scribd.com/user/270125049/Teo-En-Ming <https://www.scribd.com/user/270125049/Teo-En-Ming>===END SIGNATURE===

Upcoming changes to downloading AltArch .iso images
by Anssi Johansson 08 Oct '18

08 Oct '18

Hi, this notice is for those who employ some sort of an automation to download AltArch (ie. aarch64, armhfp, i386, power9, ppc64, ppc64le) CentOS 7 .iso/.raw.xz images from mirror.centos.org. Those using a regular browser to download these images are not particularly affected, and you can continue to the next message. Previously, only main architecture .iso image downloads from mirror.centos.org were redirected to isoredirect.centos.org, which then displayed the user a list of nearby external mirrors. We will shortly extend this configuration to cover AltArch image downloads as well, ie. direct AltArch image downloads from mirror.centos.org will no longer be possible. mirror.centos.org will still serve .rpm downloads for all architectures as before. There are two reasons for the change. First, to save bandwidth from mirror.centos.org nodes directly managed by the CentOS Project. Most of these mirror.centos.org hosts are also used for seeding the 600+ external mirrors we have. By directing some of that .iso download traffic to external mirrors we can offer faster sync speeds for those external mirrors, and for people downloading individual rpms from mirror.centos.org. Second, most of those external mirrors offer faster download speeds to end users than what could be achieved by downloading from mirror.centos.org, so the users will benefit from this change as well. The above change will be implemented some time between the releases of RHEL 7.6 and CentOS 7.6.18xx, so that external mirrors syncing CentOS 7.6.18xx content would not need to fight for bandwidth between AltArch .iso downloaders. The other change, which has already been implemented, is related to how isoredirect.centos.org behaves when accessed with curl or wget. If you now do a "wget http://isoredirect.centos.org/altarch/7/isos/i386/CentOS-7-i386-Everything-…", isoredirect will notice that you are trying to download the file and will redirect the request to the nearest external mirror. If you access the same URL with a regular browser, you will see a list of nearby mirrors from which you can pick your favourite mirror. wget will follow redirects by default, but curl needs a --location switch to follow redirects. If a filename is not specified, you will get a list of mirrors regardless of the browser used. So, combining the effects of the above two changes: If you currently use some sort of a script that downloads AltArch .iso images from mirror.centos.org, those requests will soon be served by external mirrors instead of mirror.centos.org. In the case of wget you will only see one additional request and you probably don't need to change anything, but if you use curl, you must add the --location switch to curl to follow the redirect issued by isoredirect.centos.org. If you want to eliminate one redirect, you can change mirror.centos.org to isoredirect.centos.org in your script. The rest of the URL is the same, ie. /altarch/<release>/isos/<arch>/<filename.iso or .raw.xz> As an aside, even though mirror.centos.org nodes are managed by the CentOS Project, those servers and their hosting are donations from various organizations. If you think your organization could donate an additional server to share the load and to give us better geographical coverage, please see https://wiki.centos.org/Donate If you have questions regarding this change, please let me know. Thanks!
