mysql
by Steve Clark 05 Jun '12

05 Jun '12

Hello List, I see that installing mysql in Centos 6.x creates a mysql user with a login shell of /bin/bash. Is a default password also installed? I certainly hope not, but it makes me nervous. -- Stephen Clark *NetWolves* Director of Technology Phone: 813-579-3200 Fax: 813-882-0209 Email: steve.clark(a)netwolves.com http://www.netwolves.com

rsyslog.conf - why the "-" in this entry? mail.* -/var/log/maillog
by James B. Byrne 05 Jun '12

05 Jun '12

In dealing with an unrelated issue I came across this in rsyslog.conf. # The authpriv file has restricted access. authpriv.* /var/log/secure # Log all the mail messages in one place. mail.* -/var/log/maillog # Log cron stuff cron.* /var/log/cron Why is there a "-" before /var/log/maillog? This character is not present before any of the other log files specified in /etc/rsyslog.conf. I have looked in the documents to discover the purpose of the leading "-" character in the mail log file specification but either I missed the reference or it is not there to be found. -- *** E-Mail is NOT a SECURE channel *** James B.

custom kernel build
by Jerry Geis 05 Jun '12

05 Jun '12

Hi all, I have donwloaded 2.6.32.59 from kernel.org, extracted the source, did make menuconfig to select/deselect items then did make bzImage, make modules, make modules_install, make install and rebooted. first message I got was that ext4 was not supported. So I verified that ext4 was selected and it was. So I looked at the size of the /boot/initramfs* items. My custom one is really small compared to the normal one. My question is - what controls the items that get put in there (the initramfs stuff) when you do a "make install" for a custom kernel? Clearly it is not picking up the "normal" centos items that are in the other initramfs files. Thanks, Jerry

gnome / gdm mess
by Philippe Naudin 05 Jun '12

05 Jun '12

Hello, My first attempt to install Gnome is not a bright success. If I boot in runlevel 5, using gdm, I get the login screen, but after login I get sometimes only the root window (no icons, no toolbar, no menu, nothing but keyboard shortcuts), sometimes the icons are here but not the toolbars... If I use startx from runlevel 3, everything is fine. As I don't know Gnome, I have very probably messed something during install (CentOS-6, x86_64, using uptodate netinstall iso, starting from Minimal Desktop). But I have no clue about where to look, or how to debug it. Can someone point me to some useful doc ? P.S. I'm surprised to see gdm and X running on tty1 (in runlevel 5, not 3). Is it correct ? Thanks for your help, -- Philippe Naudin

R packaging question
by Weiner, Michael 05 Jun '12

05 Jun '12

I have been working on packaging (for internal use only) multiple versions of R (eg 2.14.1, 2.14.2, 2.15.0) such that I can install these RPMs and provide the different versions of R (especially 2.14.x and 2.15.x) to the biostatisticians that require them. I have been messing around with the R.spec file but I have been unable to get the package to provide R in the location I would like: /usr/lib64/R-2.14.1/ /usr/lib64/R-2.15.0/ Now I know this can be done but I am just having some difficulty in getting it to work correctly. I have tried multiple variations in the spec playing with adding -%{version} to the paths within the spec file, as well as even using -libdir=/usr/lib64/R-%{version} which works to a point, but basically provides: /usr/lib64/R-2.14.1/R/ /usr/lib64/R-2.15.0/R/ I have attached the spec file I have been modifying and would appreciate any insights into getting this packaging correct.

Dual NVidia cards, dual monitors
by Steven Chall 04 Jun '12

04 Jun '12

I've just installed CentOS 6.2 on an HP xw8600 with two NVidia GeForce 8800 GT video cards in it. I have two Dell monitors than ran configured as a single contiguous desktop when this was a Windows 7 machine. I've only been able to access one of the two monitors under CentOS, although the system demonstrates some awareness of the second GPU/monitor, because the second monitor shows the standard CentOS 6 image while the machine is running. In addition, when it's starting up or shutting down a large wait cursor is displayed in that second monitor, and also shows the message "shutting down..." when that's going on. However, the Display applet in the System | Preferences panel menu shows only the one monitor, and hitting the Detect Monitors button doesn't help. Just to test the obvious, I switched the DVI cables coming out of the two video cards and as you'd expect what shows in the two monitors is also switched. When I do an lspci at the command line I see at the bottom of the listing: 60:00.0 VGA compatible controller: nVidia Corporation G92 [GeForce 8800 GT] (rev a2) 80:00.0 VGA compatible controller: nVidia Corporation G92 [GeForce 8800 GT] (rev a2) And the output from xrandr is: Screen 0: minimum 320 x 200, current 2560 x 1600, maximum 8192 x 8192 DVI-I-3 connected 2560x1600+0+0 (normal left inverted right x axis y axis) 646mm x 406mm 2560x1600 59.9* 1280x800 59.9 DVI-I-4 disconnected (normal left inverted right x axis y axis) I've done some considerable googling, and haven't found any discussions that offer a solution for my situation (dual video cards). I did see the following from almost two years ago saying X Windows just doesn't support it: >From http://permalink.gmane.org/gmane.comp.freedesktop.libdlo/448, Bernie Thompson says (on October 13, 2010): <begin quote> On Wed, Oct 13, 2010 at 1:44 AM, Christoph Rissner <c.r@...<http://gmane.org/get-address.php?address=c.r%2dxV8MHogwf5Dk7%2b2FdBfRIA%40p…>> wrote: > I think I've read somewhere that even XRandR 1.3 isn't up to multi GPU > environments, so I guess Xinerama is the only option here. Yes, unfortunately that's the fundamental problem. http://superuser.com/questions/139818/ubuntu-10-04-not-detecting-multiple-m… I really only understand the low-level stuff (framebuffer driver), but here's my understanding ... The plumbing isn't there in X to support multiple graphics cards the way Windows has since Win 98. The main low-level features xorg needs are in the area of things like "GPU object" and "shatter" support to allow screens to be split across GPUs/framebuffers. Right now, with RandR hand-config, you can get multiple X screens [can't drag windows between them], one per-GPU, each of which can have multiple monitors connected if that particular GPU reports multiple outputs. With GPU object support, rendering could span GPUs and several GPUs could be merged into one X screen similar to the classical Xinerama setup. <end quote> So is this [still] the case? Is Xinerama a viable alternative? I'd also appreciate some help with the "RandR hand-config" that Bernie mentions. Thanks for any info you may be able to provide. -Steve Chall Senior Research Software Developer Renaissance Computing Institute (RENCI) Phone: 919-681-9639 Email: stevec(a)renci.org<mailto:stevec@renci.org>

Using UTF8 under mysql in Centos6
by C. L. Martinez 04 Jun '12

04 Jun '12

Hi all, I am trying to configure utf8 in mysql under centos6 to display special characters, like accents. I use this mysql instance to store plain syslog logs. I have configured this under my.cnf: [mysqld] init_connect = 'SET collation_connection = utf8_general_ci' init_connect = 'SET NAMES utf8' character-set-server = utf8 collation-server = utf8_general_ci [client] default-character-set = utf8 but it doesn't seems to work ... Any idea?? Thanks.

nodejs based website
by Tim Dunphy 04 Jun '12

04 Jun '12

Hello, I am trying to setup a node.js based website called 'hummingbird'. It's a monitoring package that you can read about here: http://projects.nuttnet.net/hummingbird/ My question is when I hit the site all I see is a directory listing http://107.21.183.42/hummingbird/ Similar to what would happen if you went to a php site without php being configured in apache with the lines LoadModule php5_module modules/libphp5.so AddHandler php5-script .php I've never actually setup a node.js based site before and I was wondering if there might be something I was missing. I'd appreciate any advice you might have. Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B
