Verifing: CentOS 5 cannot resize a *live* root filesystem
by Robert Heller 18 May '16

18 May '16

Just want to verify: CentOS 5's FS utilities are too old to safely resize a *live* (mounted, etc.) root file system (and the CentOS 5 installer/rescue system does not include either resize2fs or fsadm utilities). I am presuming I will need a full-fledged Live CD/DVD to resize the root file system. This is for an old 32-bit laptop that presently has CentOS 5.11 on it -- I want to shrink the root file system (it is LVM) and make a separate /home file system, then upgrade it to something newer (not C6, since it is not PAE -- I'm *hoping* Ubuntu's 32-bit installer can deal with a non-PAE 32-bit system). -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller(a)deepsoft.com -- Webhosting Services

Has AuthEnv.pm been superseded? Should I be using Env.pm, instead? mark

Little update on my private server
by Andreas Benzler 18 May '16

18 May '16

Hello Nux, in the mean while I update straight forward my repo for tests in case of multimedia. - ffmpeg 2.8.7 (I know ffmpeg 3 is there, but can break multimedia everywhere - must take a look). - x264-debuginfo-0.148-1.20160118git5c65704 - libdvdnav 5.0.3 - libdvdread 5.0.3 - libdvdcss 1.4 rebuilt my vlc, mplayer & gstreamer-plugins-ugly against this libraries. Everything works well. Got in mind upgrade x264 can effect handbrake and xine in your repo. http://centos.cms4all.org/centos/7/gstreamer/SRPM/ Everything can be found here. I don't know if your are interested, but you can find makemkv 1.9.10 with a little new structur: makemkv-common (libraries in /usr/bin/lib64) makemkv-bin (need for vlc or xmbc /kodi) to play crypted blu ray) makemkv-oss the qt application vlc 2.2.3 can be compile straight forward. xmbc & kodi if you like (take a look at the specs): xmbc 13.2 , old but worked here good kodi 16.1 more depends both versions work with xbmc.plugin.makemkvbluray.zip blu ray - 0.9.2 libaacs 0.8.1 (not needed by me, because i use makemkv - the only one wiche works for me) Everthing can be found at http://centos.cms4all.org/centos/7/media/SRPM/ Wine-dev 1.9.10 compiled but not tested. http://centos.cms4all.org/centos/7/wine/x86_64/ beside i compiled gimp 2.8.16 (needs elrepo) because i integrate help-browser. http://centos.cms4all.org/centos/7/other/SRPMS/ Netbeans 8.1 (full package - Oracle-Jdk1.8-92-1), because netbeans works best with oracle java. http://centos.cms4all.org/centos/java/SRPMS/ I'm not crazy, I work on my machine with long term security fixes :-) What I'm doing: Watch Video private develop java, php, with databases.

Xwindow: unable to connect to display in CR 6.8
by Gilbert Sebenste 17 May '16

17 May '16

Hello everyone, I just installed the CentOS 6.8 updates from the CR repository, and then I rebooted the server. I run some software to make weather images on a website, and I have run into a problem. When I do it, the software, as it tries to plot the image, says: Xwindow: unable to connect to display It just stopped working when I did the updates. Has anyone else seen this, or have an idea on what to look for to get this fixed? To plot it, I use syntax's of machine:0 machine:1 machine:2 Which lets me plot it using virtual frame buffers (Xvfb). When I do xhost + servername , it says it has been added to the control list...but it still doesn't fix the issue. Does anyone know what I may be doing wrong?

Rsyslog on C7
by Adrian P. van Bloois 17 May '16

Hi, I have problems with rsyslog on C7. In /etc/rsyslog.d/iptables.conf I have: # Log all iptables stuff separately :msg, contains, "iptables: " { action(type="omfile" file="/var/log/iptraf/info") stop } THis works fine. In /etc/rsyslog.d/mail.conf I have: # Log all the mail messages in one place. if ($syslogfacility-text == 'mail') then { action(type="omfile" file="/var/log/mail/info") stop } This does not work, neither does a line like: mail.* /var/log/mail/info if I put that in /etc/rsyslog.conf. What am I doing wrong??? Here is my /etc/rsyslog.conf: # rsyslog configuration file # For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html # If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html #### MODULES #### # The imjournal module bellow is now used as a message source instead of imuxsock. $ModLoad imuxsock # provides support for local system logging (e.g. via logger command) $OmitLocalLogging off $ModLoad imjournal # provides access to the systemd journal $ModLoad imklog # reads kernel messages (the same are read from journald) $ModLoad immark # provides --MARK-- message capability # Provides RELP syslog reception $ModLoad imrelp $InputRELPServerRun 2514 # provides RELP syslog transmission $ModLoad omrelp #### GLOBAL DIRECTIVES #### # Where to place auxiliary files $WorkDirectory /var/lib/rsyslog # Use default timestamp format $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat # File syncing capability is disabled by default.

ipmitool and CentOS 7
by m.roth＠5-cent.us 17 May '16

17 May '16

On Dells running CentOS 6, we could use this command ipmitool delloem lcd set mode userdefined "$(uname -n | sed -e 's/\..*//' )" to set the little LCD screen to display the system name, In the latest sevens, it fails, and gives me usage for the command... which displays exactly that syntax. Anyone have a clue? mark

devtoolset-4
by Jarosław Bober 17 May '16

17 May '16

Hello, my name is Jarek I am new here. I need some clarifications on how to distribute an app developed with devtoolset-4 enabled. I am developing a distributed app in c++ I wanted to upgrade toolchain to use new standard. Is it true that when I compile on centos 6.x with devtoolset enabled then I will be able to run this app on centos 7.x as well? Do I have to install devtoolset on all my machines that I want to run this app? Or would it use built-in libstdc++ library, linking statically only the missing parts? This confuses me a bit. Regards, -Jarek

C7 Desktop background
by Rob Kampen 17 May '16

17 May '16

Hi Just stumbled into a problem with my recent new build C7 work station. Fully updated, gnome desktop, all was working well until I had a play with Tweak Tool, I wanted to try some other themes for window layouts as the default seems to not show check boxes correctly in all situations. I haven't yet determined what is causing this but suspected another theme may work better, as not being able to see the correct status of a check box is somewhat frustrating. So I made and tried numerous changes with this Tweak Tool, but only used the items that were installed as default installed select options, no special import of any other themes or extensions. At one point I lost the Desktop background - cannot recall which change triggered this, however as I have tried all the other options on just about every tab, I still have a gray desktop. If I move the cursor to the top left corner and it shows all the open windows, the desktop wallpaper / background shows just fine, but when I select any window/app, my desktop reverts to gray. I have tried resetting the desktop background but it does not remove this aberration. Any gnome gurus out there that can point me to the gnome foo required to get my desktop looking 21st century and not like my old monochrome Windows386 circa late 1980's. Thanks Rob

Black screen after install / Centos 7.2
by Oliver Zemann 17 May '16

17 May '16

Hi, i just installed CentOS 7.2 on my little "server" but i get a black screen during boot. It is a Asrock Am1h-itx mainboard with an AMD 5350 CPU (onboard graphic). I created a raid 6 but i dont think thats the problem, as the boot process goes pretty far. I would even say its going until X should start, but it is a server install, so i guess there is no X. Can someone tell me what could i do to get more information? Is there some kind of nomodeset param available for the grub cmd line param which i could try? Thanks
