Hi folks,
Is able SAMBA on CentOS 7 to work as Active Directory Domain Controller? If
it's not, what is the recommended way of doing? Compiling from sources?
Install packages from SerNet?
Thanks in advance!

Everyone,
I am looking for a utility that I can use to do a mail merge of data to
a pdf image file. The image file does not have any active fields, but
will be just an image file. I would like to overlay names addresses
etc.
We currently do this with a pcl file by just overlaying the data with
pcl print positions. However, in order to get the pcl file from an
original pdf file we have to use gimp to convert the pdf to pcl file,
and we always lose a little resolution. I was wondering if …
[View More]anyone knows
of a utility to perform this function without first converting the image
to a pcl file.
Thanks,

Dear List,
We have noticed a variety of reproducible conditions working with sparse files on multiple servers under load with CentOS 6.4.
The short story is that processes that read / write sparse files with large "holes" can generate an IO storm. Oddly, this only happens with holes and not with the sections of the files that contain data.
We have seen extremely high IO load for example copying a 40 or 80gb sparse file that only has a few gigs of data in it. Attempts to lower the io …
[View More]priority and cpu priority of these processes do not make any measurable difference. (ionice, nice) This has been observed with processes such as:
cp
rsync
sha1sum
The server does have to be under some load to reproduce the necessary conditions. The cases we have seen involve servers running 10-30 guests under kvm. Load is in acceptable norms when the processes are run, such as load avg 5-15 on a 24 core (12 core with HT enabled) server. We also verify before starting such a process that the spindle with the file we're working on is not being unduly hammered by another process.
These servers have one hardware raid controller each (Dell H700 controller with write cache enabled) and multiple raid arrays (separate sets of physical spindles). Interestingly, the IO storm is not limited to the array / spindles where the sparse file resides but affects all IO on that server.
We have looked extensively and not found any account of a similar issue. We have seen this on configurations that are 'plain vanilla' enough to think that this is not something specific to our environment.
Wondering if anyone else has seen this and if any suggestions on gathering more data / troubleshooting. We wonder if we've found either a raid controller driver issue, an OS issue or some other such thing. What seems to point in this direction is that even with ionice -c3 which should prevent the process from using IO unless the storage is idle, an io storm which appears to saturate the entire raid bus on a given server can occur.
Thanks in advance.

Hello!
I'm trying to install Centos 6.4 64 bit on this Xserve:
http://www.everymac.com/systems/apple/xserve/specs/xserve-intel-xeon-2.8-ei…
I got a bootloader from:
http://blog.christophersmart.com/2009/07/23/linux-on-an-apple-xserve-efi-on…
as none of the official Centos releases (full, minimal, network 64 bit) boot on this machine.
They all crash when loading the bootx64.conf.
I have built a USB stick with a working bootx64.efi, grub.cfg, together with an initrd and a vmlinuz

These seem to get me into booting a kernel until something called IPMI is starting to throw

I found this bug fix report
http://lwn.net/Articles/616130/
I thought we were not able to get Chromium for C6. Apparently it looks like
the work has been already done.
Is it possible we (hi Johnny) can get this package into C6? This would be a
wonderful addition to CentOS 6. Please and thank you.
Hey All,
Has anyone had trouble with Firefox/Thunderbird?
When I log on if I start Thunderbird first then I can't start Firefox.
Clicking on a link in an email fails to start Firefox.
If I start Firefox before Thunderbird then hyperlinks in emails open a
page in the existing Firefox instance.
Other users on this same machine are having the same problems.
This has been happening for that last several days.

Hi All,
I am switching from Fedora20 to CentOS7 since I now run all my Linux
development in a VM and I get a more robust feature set (i.e. shared
folders with the host that "just work", etc)
The only issue I have thus far is VPN connections. Looking at what's
installed on my old Fedora install I suspect I need these packages:
kde-plasma-nm-vpnc
kde-plasma-nm-openvpn
NetworkManager-openvpn
NetworkManager-vpnc
However none of these are available in CentOS7, Note I have the centos
extras …
[View More]and the EPEL repos enabled. I suspect that I need rpmfusion but
I don't see that rpmfusion has a repo for CentOS7...
Anyone have any thoughts? Can I simply install the centos6 rpmfusion repo?
Thanks in advance

Hi guys,
I'm yet to use 10 Gbps with CentOS, hence my question. I'm looking for a cheap (doh) adapter that won't cause me problems with CentOS. Any recommendations?
Cheers

Everyone,
I have installed Centos 7.0 on my homework machine in order to take a
test drive with it, and am low on the learning curve with it at this
point. I have a small Gateway SX2855-UB12P.
I have a critical hurdle in that when I try a reboot or when I do a
'shutdown now -r' command the system will start a reboot process but
hangs right after the os choices are presented.
My install process started with the server version, and I added the
gnome desktop latter. I also changed the boot …
[View More]level to 5.
Has anyone else had this problem, or any suggestions as to a remedy.
Thanks,
Greg Ennis
