Sudo #includedir function ignored CentOS 6
I am unable to get the #includedir function to work with sudo. This works just fine on all my CentOS 5.6 servers, but on 6 it is being ignored. I have this line in the file /etc/sudoers.d/zabbix-puppet zabbix ALL=NOPASSWD: /var/lib/zabbix/bin/start_puppet However sudo still requires a password. If I put that same line into /etc/sudoers file , there is

Running Apache sites as separate users
I had a recent request to improve security on my web servers by having each website use a different user to run the hosting service. So example1.comhas it's own Apache instance running as apache1 and then has its own instance of Apache as apache2. Is this even possible or realistic? I understand the idea of how that would be secure, much like creating a virtual machine to

SELinux triggered during Libvirt snapshots
I recently began getting periodic emails from SEalert that SELinux is preventing /usr/libexec/qemu-kvm "getattr" access from the directory I store all my virtual machines for KVM. All VMs are stored under /vmstore , which is it's own mount point, and every file and folder under /vmstore currently has the correct context that was set by doing the following:

SELinux and SETroubleshootd woes in CR
I'm setting up a dedicated database server, and since this will be a central service to my various web servers I wanted it to be as secure as I am leaving SELinux enabled. However I'm having trouble getting Apache to use mod_auth_pam. I also now can't get setroubleshootd working to send me notifications of the denials and provide tips to solve the problem. The Apache

Using Samba to share Apache web root, securely
I'm setting up a shared web server running Apache. Each web root will belong to a department, which has a corresponding Active Directory group to give access. So far I've got samba working and such, but am having some trouble wrapping my head around the necessary permissions to make all this work, especially securely. So far I've found that both the POSIX and the ACL permissions

CentOS 6 x86_64 DVD doesn't boot
Hi Everyone, I downloaded the CentOS 6 x86_64 DVD ISOs and burned the first image to a rewritable DVD. When I tried to boot my new home server off it, it didn't, and then this was printed to the screen: ETCDisolinux: Found something at drive = EF No DEFAULT or UI configuration directive found! boot: The same disc works fine in my 4 year old HP laptop, and when installing CentOS 6 as a KVM.

Official puppetlabs position on cron vs puppet as a service?
Over the years many shops have come to start running puppet via cron to address memory leaks in earlier versions of Ruby, but the official position was that puppet was meant to be run as a continually running service. I am wondering if the official position has changed. On one hand many if not all of the early Ruby issues have been fixed, on the other, the addition of mcollective into the mix as

Excluding RAW disk from snapshot
I have an oVirt engine node that currently runs the system on a qcow2 based virtual disk, and an NFS export volume on RAW. I'd like to take a snapshot before a somewhat risky upgrade of oVirt and can't with the raw image attached. Looking at the documentation for the snapshot XML, I created this XML file for the snapshot <domainsnapshot> <name>20120802</name>

CentOS 6 DVD install "Unable to read group information from repositories"
Tried my first CentOS 6 install on a system currently running 5.6. My attempt was not an upgrade, but a full re-format. I have verified the checksums of the ISO and did the pre-install disk verify and everything checked out. However after the screen for setting up the bootloader I get the following error "Unable to read group information from repositories. This is a problem with the

Catalog compile times > 40s - Puppet 2.7.18
I am finding that the puppetlabs-apache module is somehow adding 30-60 seconds onto a host''s catalog compile time when the puppetmaster has no other hosts contacting or generating catalogs. The Puppetmaster is setup to use Puppet-2.7.18 - Apache & Passenger. RIght now only 2 hosts are even configured to use this new PM, the PM itself and a Foreman host. With neither hosts

Libvirt daemon usage question
I could use some help with clarification on the use of the libvirtd daemon with regards to managing remote KVM instances. Right now I have a CentOS 6 KVM server (libvirt-0.8.1), but would like to use some management applications that require higher version (0.8.8). First, is it possible to run the libvirtd daemon from within a VM, or does it require active kvm kernel module? Secondly, could a

Lookup another node's hiera data - fqdn hierarchy
I''ve begun using Hiera in combination with Foreman, primarily storing data that is best left in Array/Hash form. I''d like to be able to have a module, in this case BackupPC, query all the Hiera data for each node where the backup directories/databases are stored. Then use all that information on the BackupPC server to generate proper configuration files for each

Upgrade from CentOS 5.x to 6.0
Great news about CentOS 6.0 being available, and I figured I'd ask the most obvious question, what can I expect when upgrading from CentOS 5.6 to 6.0? I have not had to go from one major version of CentOS to another so this is new territory for me. Is the processes just like an install except there's an "Upgrade" option? Does an upgrade do a "yum update" of

Using back-ported create_resources in 2.6.x
Does anyone have some examples of using this create_resources function,, ? Based on the README example I can''t figure out exactly how to change from using defines to using this function. Maybe I misunderstand the purpose of it to replace defines, or is it to allow ENCs (for example) to use a
