Upgrade path from CentOS 7 to future versions
by Venkateswara Rao Dokku 11 May '16

11 May '16

Hi, I would like to know whether the valid upgrade path will be present from CentOS 7 to future versions like we get for Ubuntu or some other operating systems. Right now, I am sure that we do not have proper update path in CentOS to move from one version to another. -- Thanks & Regards, Venkateswara Rao Dokku.

OT: Linksys router misbehaviour
by Timothy Murphy 11 May '16

11 May '16

I'm running a Linksys WRT54GL router from my CentOS-7 home server. Every now and then (maybe once every 2 days) the router's WiFi cuts out, and I've found no way to solve this except to disconnect the power from the router, wait 10 seconds and then re-connect. This always works. The router is running under dd-wrt. My question is - which makes it a tiny bit CentOS-related - does anyone with such a router know of a way to wake the router up in such a case through the computer? I wouldn't have dared to ask this question here or anywhere until recently, as I assumed my ancient Linksys routers were obsolete. But I've been reading posts recently saying that there hasn't really been a Linux router to replace the WRT54GL, and in particular Linksys's recent 11n replacement is not as good as the old model in many ways. Anyway, if anyone has an answer to my query I would be very grateful. I have a couple of IP cameras working by WiFi on the computer, which I can look at remotely. I've connected one by TP-Link through the router, and this doesn't cut out, but it is not wholly satisfactory. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Cannot figure out what this segfault message means. Please help!
by Sean Son 11 May '16

Hello all I installed MySQL 5.7 using the Mysql community YUM repository and I also installed Tomcat 8 from tomcat.apache.org. The installations went fine but ive been noticing that the VM,which is running CentOS 7.2, has been freezing periodically. This morning when I checked the VM i saw the following segfault message: kernel:systemd[1]: segfault at ffffffffffffffff ip ffffffffffffffff sp 00007ffde89aa040 error 15 and kernel:systemd[1]: segfault at fffffffffffffe0f ip 00007f96bdd021ad sp 00007ffde89a8370 error 5 in systemd[7f96bdc2a000+146000] how do I interpret these error messages and are there any bug fixes out there for these errors? I am using kernel: 3.10.0-327.13.1.el7.x86_64. The VM is running on Hyper-V 2012. Thank you for all of your help!

Re: [CentOS] Badlock bad luck

I'm seeing the exact same behavior in my environment (NT4 PDC, not AD). I had to downgrade samba get systems working again. The full error message is: "The trust relationship between this workstation and the primary domain failed". Did you have any luck finding a solution?

Re: [CentOS] test builds on mesa

Correct my self: libdrm version is 2.6.8 mesa 11.2 needs libdrm < 2.6.6, can be compile with the centos private-llvm 3.6.1 mesa 11.1 libdrm < 2.6.1 mesa 10.6.9 can build without external upgrades. Rebuild mesa, only needs cms4all-drivers. If you are use wine, you need it twice x86_64 and i686 Sincerely Andy

Unexpected behavior of 'yum group list' and 'yum group install'
by Nicolas Kovacs 11 May '16

11 May '16

Hi, I'm currently experimenting with Yum on a fresh CentOS 7 minimal install, and I'm getting some puzzling results. Here's what I did. 1. Install CentOS 7 from the Minimal CD. 2. Install 'deltarpm' and update all packages. 3. Install the "Core" package group: 'yum group install "Core"' 4. Install the "Base" package group: 'yum group install "Base"' 5. As expected, 'yum group list hidden | less' shows this: ... Installed Groups: Base Core ... 6. Now I remove manually all packages that were not present in the initial installation. I'm doing this using a script, which is supposed to get the system back to its pristine state. Various tests with 'rpm -qa --queryformat '%{NAME}\n' | sort > packagelist.txt' show me that this worked. 7. For mysterious reasons, 'yum group list hidden | less' still shows: ... Installed Groups: Base Core ... 8. When I try to reinstall the "Core" and/or the "Base" groups using 'yum group install "<Group>", I get the following result: # yum group install "Core" Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp.pasteur.fr * extras: mir01.syntis.net * updates: ftp.pasteur.fr Maybe run: yum groups mark install (see man yum) No packages in any requested group available to install or update 9. As you can guess, the expected behavior was for Yum to *not* display the "Core" and "Base" groups as "Installed Groups" as soon as there was some stuff (if not downright all packages from the group) missing. Any suggestions on this? Cheers from the rainy South of France, Niki PS: you may wonder why I'm doing this. I may have to manage a situation where I have to deal with CentOS 7 installations that would first have to be pruned down without reinstalling everything. -- Microlinux - Solutions informatiques durables 7, place de l'église - 30730 Montpezat Web : http://www.microlinux.fr Mail : info(a)microlinux.fr Tél. : 04 66 63 10 32

These files are included in both my /etc/named.conf and /usr/share/doc/bind-x.x.x/named.conf.default which I probably used as a template years ago. I'm no dns expert but you'd probably need these files when accessing root servers directly without use of forwarders. I'm also using ddns and have my zone files in /var/named/chroot/var/named/dynamic. Selinux is enabled and I don't see any additional bind-related rules in my local policy or /etc/selinux/targeted/contexts/files/file_contexts.local.
