how to unrar
by Michael Hennebry 25 Oct '15

25 Oct '15

I'm looking for a means to unrar some files. Google keeps giving references to rmpforge which I'm told I ought not use. Any other ideas? I'm running centos 6. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

Re: PHP version not enough for developers

I believe that there is a perceived convergence of "needs" between (call it...) more-mobile personal linux and _virtualised_ server linux. If we can create a linux VM in under 5 minutes, "we" expect that it will boot-up without the sys admin's intervention. Then "we" expect that we can migrate it to newer hardware without manual reconfiguration. But returning to PHP: If apps are developed without real separation between user interface and back-end, then the back-end will be victimised by the relative and inherent instability of the front-end. The web servers then really become part of the front-end and must be handled as such. I would argue that this lack of separation between front-end and web server is a feature of the WWW and its protocols, we cannot escape it. So no surprise that most data centers leave the web servers outside or mostly-outside the network perimeter.

OpenSSL and OpenSSH on CentOS (FIPS enabled)
by Ning Liu (niliu2) 24 Oct '15

24 Oct '15

Hi experts, Current I am doing FIPS gap analysis for our product, can someone help to have a look my questions? Our product is server running under CentOS 6.x, and according to the upstream (RedHat) document, CentOS can be configured to FIPS mode: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/ht… And according to the CentOS forum, if we enabled FIPS mode on CentOS, then OpenSSL will also be in FIPS mode https://www.centos.org/forums/viewtopic.php?t=9078 Questions: (1) Is that true for OpenSSL ? (2) How about OpenSSH, since we are using SSH for administration, but there is not too much document mentioning OpenSSH Vs. FIPS. But looks like REDHAT already takes care of OpenSSH: https://www.redhat.com/en/about/press-releases/red-hat-completes-fips-1402-… Can I assume that OpenSSH is in FIPS mode when CentOS is in FIPS mode ? Regards, Ning Liu

EFI netboot to kickstart install
by Grant Street 23 Oct '15

23 Oct '15

Hello All Up until now we have been using standard PXE boot to do kick start installs of centos boxes. With recent machines however they come by default as EFI boot. We can set them to legacy but I would like to solve this before this option goes away. Just wondering if anyone has any experience setting up a net boot server that can be used to kickstart EFI machines? Thanks Grant

OpenStack Liberty is the 12th release of the open source software collaboratively built by a large number of contributors around the OpenStack.org project space. The RDO community project ( https://www.rdoproject.org/ ) curates, packages, builds, tests and maintains a complete OpenStack component set for RHEL and CentOS Linux and is a founding member of the CentOS Cloud Infrastructure SIG ( https://wiki.centos.org/SpecialInterestGroup/Cloud ). The Cloud Infrastructure SIG focus on delivering a great user experience for CentOS Linux users looking to build and maintain their own onpremise, public or hybrid clouds. In addition to the comprehensive OpenStack services, libraries and clients, this release also provides Packstack, a simple installer for proof-of-concept installations, as small as a single all-in-one box and RDO Manager ( https://www.rdoproject.org/RDO-Manager ) , an OpenStack deployment and management tool for production environments based on the OpenStack TripleO project. ------- QuickStart: Ensure you have a fully updated CentOS Linux 7/x86_64 machine, and run : sudo yum install centos-release-openstack-liberty sudo yum install openstack-packstack packstack --allinone For a more detailed quickstart please refer to the RDO Project hosted guide at https://www.rdoproject.org/QuickStart For RDO Manger consult https://www.rdoproject.org/RDO-Manager page. RDO project is closely tracking upstream OpenStack projects using the Delorean tool[1] which is producing RPM packages from upstream development branches. Since the previous OpenStack Kilo release, RDO is participating in the Cloud SIG and using CentOS provided infrastructure. Towards the end of developement cycle packages are imported into CentOS Cloud SIG buildsystem[2] and get eventually published in Cloud SIG repositories[3]. [1] http://trunk.rdoproject.org/ [2] http://wiki.centos.org/HowTos/CommunityBuildSystem [3] http://mirror.centos.org/centos/7/cloud/x86_64/ -------- Getting Help: The RDO Project provides a Q&A service at ask.openstack.org, for more developer oriented content we recommend joining the mailing list at https://www.redhat.com/mailman/listinfo/rdo-list. Remember to post a brief introduction about yourself and your RDO story. You can also find extensive documentation at https://www.rdoproject.org/Docs. We also welcome comments and requests on the CentOS Mailing lists ( https://lists.centos.org/ ) and the CentOS IRC Channels ( #centos on irc.freenode.net ), however we have a more focused audience in the RDO venues. To get involved in the OpenStack RPM packaging effort, see https://www.rdoproject.org/Get_involved and https://wiki.centos.org/SpecialInterestGroup/Cloud Join us in #rdo on the Freenode IRC network, and follow us at @RDOCommunity on Twitter. And, if you're going to be in Tokyo for the OpenStack Summit next week, join us on Wednesday at lunch for the RDO community meetup ( http://sched.co/4MYy ).

Centos 7, ATI/AMD video, fonts
by m.roth＠5-cent.us 22 Oct '15

22 Oct '15

A newly built CentOS 7.1 system, with an ATI/AMD video card. I installed the proprietary driver (this is a Dell, and they had their own rpm), and after I ran aticonfig --initial, init 3, then init 5, and we have a working video. Excerpt the fonts are atrocious. All the letters seem to be missing pixels, so it's as though there's no across, almost. He's running gnome. There has to be a quick fix - a link would be great. Thanks in advance. mark

PHP version not enough for developers
by Andrew Holway 22 Oct '15

22 Oct '15

Hi, So, it seems that the current version of PHP in Centos 7 is PHP 5.4.16 however this version of PHP stopped getting security support from the PHP people one month ago [1]. Now, our developers want to use the new and shiny PHP because they want to use the latest version of Zend. They are proposing using this package [2] but I never heard of this repo. Other than building the packages ourselves is there a more acceptable way to run a later version of PHP? Thoughts? Experiences? Ramblings? Ta, Andrew [1] - http://php.net/supported-versions.php [2] - https://webtatic.com/packages/php56/

CentOS7 - Serial Console and Flow Control
by Mike - st257 22 Oct '15

22 Oct '15

Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial redirection for the kernel do not appear to work. I've made the following changes to GRUB2's /etc/grub/default config file: -- removed rhgb -- added the console= settings to GRUB_CMDLINE_LINUX -- added the last two lines related to serial as detailed here [0]. * Is there an option to enable hardware flow control? I recall having to turn on flow control (agetty -h) to make it behave. No mention of flow control at [1] or [2]. Nor does RHEL7 doc [3] mention it. I've already tweaked the systemd service I generated for ttyS1 (I'm using COM2 for SoL) and added the agetty "-h" option (for hardware flow control). Despite modifying the baud rate to reflect the BMC's settings, I only get symbols (so the console settings are amiss). Would anyone be so kind as to share their experience? What has worked for your BMC/SoL configurations?
