Thanks! Up on kernel 3.10.0-229.7.2.el7.centos. Page http://wiki.centos.org/HowTos/Custom_Kernel specifically states using rpm and not yum for the new kernel install, so perhaps needs that slight revision for 7......Nick G On Thu, Jul 9, 2015 at 5:05 PM, Nicholas Geovanis <nickgeovanis at gmail.com> wrote: > Hi all - > First the boilerplate: > On centos-release.x86_64 7-0.1406.el7.centos.2.3 > [root at localhost x86_64]# uname -a > Linux localhost.localdomain 3.10.0-123.el7.x86_64 #1 SMP Mon Jun 30 > 12:09:22 UTC 2014 x86_64 x86_64 x86_64 G...

hostname service?
On CentOS 7, I find in /var/log/messages several times daily messages "localhost systemd: Started Hostname Service.". However I can't seem to find such a service using the systemctl command. What is the "Hostname Service", what does it do and why is it being restarted frequently? Many thanks....Nick

nsswitch.conf question
I find the passwd, shadow and group lines in my CentOS 7 /etc/nsswitch.conf file specify "files sss". I'm not familiar with the "sss" source, would someone please give me an idea what that is? Many thanks....Nick

Need firewalld clue
I don't really understand the intent behind firewalld. The RHEL7 Security Guide states "A graphical configuration tool, *firewall-config*, is used to configure firewalld, which in turn uses *iptables tool* to communicate with *Netfilter* in the kernel which implements packet filtering". So is the goal for firewalld to implement a GUI for iptables? What is the "value added"

packagekit yumBackend question, perhaps
Periodically I find the yumBackend python script of packagekit really slows down my CentOS 7 system. I don't invoke anything myself which starts it and I find nothing in crontab which does either, except perhaps /etc/cron.hourly/0yum-hourly.cron. But I can't be sure that is the culprit. I don't find anything at http://www.freedesktop.org/software/PackageKit which helps me to debug

ifenslave vs. /etc/sysconfig/network-scripts
How does the ifenslave command relate to "normal" network slave configuration in /etc/sysconfig/network-scripts? Does config-file-based setup use ifenslave or is it more complicated than that? Thanks....Nick

Thank-you to Samba developers
Here's a short quote from a work-related email I sent earlier today, announcing AD authentication from a linux VM. It expresses my awe at the folks who write and maintain Samba, and it's long overdue from me: It?s been 3 or 4 years since I configured Samba; it?s always a challenge for me, mainly due to my poor understanding of MSoft networking. Then when it works, I offer a silent prayer

Centos 6.6, apparent xfs corruption
Hi all - After several months of worry-free operation, we received the following kernel messages about an xfs filesystem running under CentOS 6.6. The proximate causes appear to be "Internal error xfs_trans_cancel" and "Corruption of in-memory data detected. Shutting down filesystem". The filesystem is back up, mounted, appears to be working OK underlying a Splunk datastore.
