The right way to deal with in-house development
by m.roth＠5-cent.us 16 May '18

16 May '18

Ok, what's the "correct" way to deal with systems developed in-house, that have their own sets up subdirectories. And why, for that matter, does running sealert give me the full path to the executable, like openjdk... but *not* the full path to the file it's trying to operate on, and I'm left going "ok, where was the file it deleted? (we're running in permissive mode - overwhelmingly, developers and subject matter experts no less than nothing about selinux). mark

CentOS 7.5 (1804) and NetworkManager
by Nicolas Kovacs 16 May '18

16 May '18

Hi, I'm running CentOS on all kinds of setups: servers, workstations, desktops and laptops. Up until now, I'm only using NetworkManager on laptops, since it makes sense to use it there. On servers and desktop clients, I usually remove it and configure the network "traditionally" by simply editing /etc/sysconfig/network-scripts/ifcfg-whatever, /etc/resolv.conf, /etc/hosts, /etc/hostname and /etc/sysconfig/network. Running NetworkManager on anything else than a laptop has never made any sense to me, since it's basically an extra layer of abstraction. With the latest update, the removal of NetworkManager on a desktop client isn't possible anymore, since 'yum remove NetworkManager' also tries to remove 'gdm', and disabling it on startup spews back all sorts of errors. If you folks at Red Hat are reading this, I have one question: WHY ?

Re: [CentOS] CentOS 7.5 (1804) and NetworkManager
by Michael Lampe 16 May '18

Gnome's control-center now requires NetworkManager-wifi. But it's only a soft requirement, no shared libs involved. To keep your workstation NM-free, you want to install a dummy package that provides NetworkManager-wifi but actually contains nothing, ideally before updating to 7.5. Here's a script to create such a dummy: https://github.com/larsks/fakeprovide If you do this, control-center shows a sad face and some text (Oops, blah, blah, ...) in the WiFi tab. Just the same you always got in the network tab without NM. That's all. -M.

OT Hardware Forum
by Mark LaPierre 15 May '18

15 May '18

Hey Y'all, Is there a forum where I can discuss hardware and CentOS 7? I'm considering building a new desktop system specifically designed for CentOS 7 and the Folding At Home project. This mail list seams to be oriented toward CentOS software issues not hardware discussions. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Issue with private mirror
by Eric Germann 15 May '18

15 May '18

Hello all, long time lurker, first time poster. I have a situation that has been confounding me for the better part of a week. I run an internal mirror of a Centos mirror, mainly because I have lots of hosts and low bandwidth. For my 7.x hosts, since 7.5.1804 was released, when I do a “yum update”, I get the following errors on a number of files. "Package does not match intended download. Suggestion: run yum --enablerepo=base clean metadata” I’ve done that. I’ve done “yum clean all”. I’ve done “yum clean all && rm -rf /var/cacheyum” I’ve blown away the 7.5.1804 tree in my mirror and resync’d it and it still does it. If I change the 7 -> 7.5.1804 symlink to 7.4, yum update runs fine. I’m confounded. How can I check the repo data files on my copy against the tree to see where or if it’s blowing up. Oddly, if I point the host I’m updating at the SAME server I’m mirroring from and do a yum update, it works fine. Using rsync to update. Out of Ideas, EKG

CentOS 7.5 and GPU memory
by Jerry Geis 15 May '18

15 May '18

Is there a way to "control" how much GPU memory the OS uses ? Back on CentOS 7.4 it "seemed" to use less. I want / need to tell 7.5 to use less.\ or no GPU memory. I have a video application that needs more of the GPU memory and not so much the OS taking that memory. How do I do that? Thanks, Jerry

Squid and log files
by Nicolas Kovacs 15 May '18

15 May '18

Hi, I have Squid running on several CentOS proxy servers. Here's what the Squid log file directory looks like on my own server: access.log access.log-20180311.gz access.log-20180319.gz access.log-20180429.gz access.log-20180506.gz access.log-20180514.gz cache.log cache.log-20180416.gz cache.log-20180422.gz cache.log-20180430.gz cache.log-20180506.gz cache.log-20180514.gz squidGuard.log I don't know if the compressed and archived *.gz log files are supposed to be erased some time. Anyway, I'd like to make sure they are kept at least for one full year. Where is this defined ?

Save the date: CERN Dojo, October 19th, 2018
by Rich Bowen 14 May '18

14 May '18

On October 19th, 2018, we will once again be hosting a CentOS Dojo at CERN, in Meyrin, Switzerland[1]. This will be a full day of CentOS presentations, drawn both from CERN and from the broader CentOS community. The call for papers is now open[2]. We're looking for talks about anything CentOS related, but we're particularly interested in: * OpenStack, and other cloud platforms * Ceph, and other software defined storage solutions * Configuration management tools * HPC, and other aspects of research computing CERN[3] is one of the best-known research facilities on the planet, and the home of the Large Hadron Collider. CentOS Dojos[4] are the best place to meet other members of the CentOS community, and the various communities - such as OpenStack and Ceph - that have a large overlap with CentOS.
