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! -- -- Sergio Belkin http://www.sergiobelkin.com LPIC-2 Certified - http://www.lpi.org

How to setup own i686 buildenv for CentOS7
by Robin Lee 07 Sep '15

07 Sep '15

Hi, all! How to setup own i686 mock for CentOS7? Or, is there any public i686 repo for CentOS7? I found i686 repo available in internal CentOS building environment, from a root.log from a mock build result[1]. [1] http://buildlogs.centos.org/c7-updates/glibc/20141218212615/2.17-55.el7_0.3… Cheers, -robin

Mail Merge data to a pdf file by overlaying the data on the image
by Gregory P. Ennis 07 Jun '15

07 Jun '15

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 anyone knows of a utility to perform this function without first converting the image to a pcl file. Thanks, -- Greg Ennis

heavy IO load when working with sparse files (centos 6.4)
by Ron E 31 Mar '15

31 Mar '15

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 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.

Centos 6.4 on Xserve, IPMI error
by Arno B 31 Mar '15

31 Mar '15

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 from the isolinux folder.

CentOS 6.6: Webcam problem

Last month we discussed the problems with webcams in CentOS 6 and I raised Bugzilla #1158988 with Red Hat. This bug has now been declared a duplicate of 1145805. Unfortunately I'm unable to access that report so although I know Red Hat are looking into the matter I don't know what they're doing. Ron

What's up with Firefox/Thundrebird

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.

When will CentOS Publish Errata?
by Somers-Harris, David | David | OPS 14 Jan '15

14 Jan '15

Hello, Currently The CentOS project publishes errata on its CentOS Announce mailing list. In order to import this into a package management system (like Katello on The Foreman), one needs to parse the mailing list and convert it into XML before importing it. This is done to some extent on http://cefs.steve-meier.de/ but some more legwork needs to be done before The Foreman can understand the errata like it does natively for RHN. I have heard rumour that The CentOS project is planning to publish Errata in the same way that Red Hat does, but I haven't been able to find anything on the Internet about this. Does anybody know if The CentOS Project has indeed declared such intention, and when they plan to do this? Side Note: Interestingly enough, I've noticed that EPEL has started to add errata data to their repositories. Thanks, David

Well, despite the hype from Wall St., Bay St. and The City, a large number of organisations in the world run on software that is decades old and cannot be economically replaced. In many instances in government and business seven years is a typical time-frame in which to get a major software system built and installed. And I have witnessed longer. So, seven, even ten, years of stability is really nothing at all. And as Linux seeks to enter into more and more profoundly valuable employment the type of changes that we witnessed from v6 to v7 are simply not going to be tolerated. In fact, it my considered belief that RH in Version EL7 has done themselves a serious injury with respect to corporate adoption for core systems. Perhaps they seek a different market? Think about it. What enterprise can afford to rewrite all of its software every ten years? What enterprise can afford to retrain all of its personnel to use different tools to accomplish the exact same tasks every seven years? The desktop software churn that the PC has inured in people simply does not scale to the enterprise. If you wish to see what change for change's sake produces in terms of market share consider what Mozilla has done with Firefox. There is absolutely no interface that is as easy to use as the one you have been working on for the past ten years. And that salient fact seems to be completely ignored by many people in the FOSS community. -- *** E-Mail is NOT a SECURE channel *** James B.

Radeon graphics problems with CentOS 6.6
by Darby Vicker 06 Jan '15

Hello, I saw in the CentOS 6.6 release notes that the Xorg ABI has changed but that "This should not concern anyone who uses the default drivers shipped with CentOS." I'm using the ATI drivers in Base but X still fails when I boot a CentOS 6.6 kernel. I was hoping this is a known problem that would get fixed with a kernel update but I'm still having problems with the 2.6.32-504.1.3.el6.x86_64 kernel. Relevant info below. Any ideas?

Fetchmail multiple instances increasing load average
by Anshul Chauhan 04 Jan '15

04 Jan '15

Hi, I’m running centos 5.7 with sendmail-8.13.8-8.1.el5_7, fetchmail-6.3.6-4.el5 and procmail-3.22-17.1.el5.centos. My server is having around 2000 mailboxes and this server used to fetch mails for all these users using fetchmail from the other MX server. I’ve configured the below cron job using webmin for downloading these mail 5,10,15,20,25,30,35,40,45,50,55 * * * * /etc/webmin/fetchmail/check.pl --file /var/log/fetchmaillog. But the load average for the server goes high automatically after every 4 to 5 hours due to multiple fetchmail instances and after that I’ve to either kill all the fetchmail jobs or restart the server for making the system up again. Kindly suggest how can i reduce this load average issue or any other way out for downloading the mails from the parent server running on sendmail again. Warm Regards, Anshul Chauhan

Secret incantations for virt-viewer?
by Bill Gee 02 Jan '15

02 Jan '15

Hello everyone - I am trying to use virt-viewer to connect to KVM virtual machines running on a CentOS7 host. It works great when running directly on the host, but I have not been able to figure out the magic connection string to make it work from another computer. On the host, I set selinux to "permissive" and stopped the firewalld service. No change, so it is not related to them. Almost every command I try gives an immediate dialog box that says "Unable to connect to libvirt with URI ...". The only command line that gets me anything different is this: virt-viewer --connect xen+ssh://root@practice7.billgee.local/ dd2a2ba7-707d-42b5-8c83-94b11ce6e269 This will ask me for the root password on the host machine and then gives me the same "Unable to connect" message. I tried it with a regular user account instead of root and got the same result. I have tried it with and without the "root@" string. I tried using both the UUID and the domain name of the guest. I tried all of the following protocols: ssh:// qemu:// qemu:/// xen:// xen+ssh:// qemu_ssh:// qemu+ssh:// If I open a regular ssh shell using the +X parameter and then launch virt- viewer, it works. The connection string in that case is --connect=qemu:///system Any suggestions? Thanks - Bill Gee

That’s all possible to work around. Home servers: SAN design points the way. Backup servers: Ditto if you mean home directory mirrors. If you mean hot failover nodes in a cluster, I already pointed out that clusters let you upgrade via temporary partitioning.

The weird thing is that I have another server with the same config/CentOS version/Net-Snmp version and I have no issues with the snmp process on that server. I could raise the open file limit but that just seems unnecessary since I don't think that snmp is supposed to work that way. Anything else I could try to troubleshoot the issue? Thanks!

There is no man page for qemu.conf, so all I can go by is the comments in the file. There are NAT routers in front of all of this. Bill Gee

The idea of incremental feature enhancement that you introduced is at once orthogonal to my original point and yet forms an ironic counterpoint that highlights the problem. The issue of data integrity is a separate matter entirely. I raised the issues of needless incompatibility and the avoidable costs of retraining and re-implementation of existing, satisfactory, solutions. You reply with a comment extolling incremental featurism. I am all in favour of incrementalism in software development. The problem being that RedHat does not do that. Instead RedHat freezes the product two years before release and then sets about creating a new, equivalent, but significantly different, replacement that you are forced to accept every seven years. In fact, the freeze, release, support and deprecate schedule that RedHat embraces as a corporate policy bears more than a passing similarity to the 'waterfall' process you, evidently prematurely, consigned to the grave. If RedHat actually adopted incremental rollout of new features to their distribution I would be most happy because, incremental rollouts are NOT SUPPOSED TO BREAK ANYTHING ALREADY IN PRODUCTION. And that condition is most certainly not met in every case of RHELx+1 I have dealt with. -- *** E-Mail is NOT a SECURE channel *** James B.

I understand that that's a "RHEL thing" but does anyone here have any insight to what this will mean. Will applications have to rebuilt? Or what other implications are there? Thanks, Dave

can't enable selinux CentOS 6.5
by Tim Dunphy 30 Dec '14

30 Dec '14

Hey guys, For some reason I can't seem to enable SELinux on this one host. Here's my SELinux config file: [root@beta-new:~] #cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=enforcing # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted And when I check if it's enabled this is what I get: [root@beta-new:~] #getenforce Disabled But when I go to set SELinux to enabled, even with the config file set as you see it above, I get this result: [root@beta-new:~] #setenforce 1 setenforce: SELinux is disabled And nothing I can do enables it on this host. So how, can I solve this problem? I would definitely appreciate any advice you may have. Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Does anyone know if you can connect an iphone 5 with ios 8.1.2 to either Centos 6 or 7? I've installed libimobiledevice but there's nothing happening. Thanks Patrick
