CentOS 7 samba server + mac client problems
by Noam Bernstein 03 Jan '17

03 Jan '17

We’ve just started to try to configure a new CentOS 7 disk server, and NFS seems OK so far, but I’m having problems with smb mounts to a Mac OS X client. I have the [homes] section as usual, and some additional shares restricted to specific users, but none seem to work. I know I’m authenticating OK (both from the smbd logs and because when I type the wrong password the Mac’s behavior is different), but in no case can I see any files. The Mac gets as far as creating a mount point and opening a blank Finder window, but it’s completely empty, and when I try to select the server in the Finder sidebar it says “Connection failed” and shows a “Connect As” button, which just initiates another login/mount dialog window. I don’t know what configuration bits are important, so I’m not sure what to include with this message. I do know that I have things set up very similarly to our previous CentOS 6 smb server, and that one seems to work fine. If anyone has gotten such a configuration working, or has any suggestions as to what options in the smb.conf file to focus on, I’d appreciate any clues. thanks, Noam

cron job failures with a perl script containing Astro::Time
by Gregory P. Ennis 03 Jan '17

03 Jan '17

Everyone, I am building a gateway server with a new : CentOS Linux release 7.3.1611 (Core) with 3.10.0-514.2.2.el7.x86_64 kernel. Everything was going find, but I was not able to get a particular cronjob to function properly that contained a perl script with Astro::Time as an include file. Astro::Time was installed with the use of the cpan module downloaded from the Centos repositories. The error message I get in the logs is : Can't locate Astro/Time.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/bin/s.bkup.degw3.prl line 12. BEGIN failed--compilation aborted at /usr/local/bin/s.bkup.degw3.prl line 12. Line 12 is the line in the perl scrip that contains : use Astro::Time; The script works find from the command line, but will not work at all in a cron job. After I reviewed the previous posts on this mail list about Centos 7 cron job problems I was motivated to change the PATH statements in the /etc/crontab file to include all of the PATH's in my root environment while using a terminal interface. /etc/crontab file : SHELL=/bin/bash #PATH=/sbin:/bin:/usr/sbin:/usr/bin PATH=/usr/lib64/qt- .3/bin:/root/perl5/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bi n:/root/bin QT_PLUGIN_PATH=/usr/lib64/kde4/plugins:/usr/lib/kde4/plugin MAILTO=root The original /etc/crontab file was : SHELL=/bin/bash PATH=/sbin:/bin:/usr/sbin:/usr/bin MAILTO=root Unfortuantely I am still not able to get this script to work. Has anyone else had this problem and found a solution? Greg Ennis

Noise Cancellation of Server Noise
by H 02 Jan '17

02 Jan '17

Has anyone come across a device that could cancel out the noise from servers, ie. the fan noise? I have a server rack near my office and would like to see if i can decrease the noise level. It would seem to me that the steady drone of the fans could be cancelled out to a large extent.

Raspberry PI3 - CentOS armv7hl gnome desktop
by Paul R. Ganci 02 Jan '17

02 Jan '17

Maybe there is a better place to post this message but as my question was still CentOS related thought I would start here. Please advise if there is a better forum of which to ask this question. I am playing around with making a "desktop" workstation out of a Raspberry PI3. I have had no problems installing the OS and pretty much have everything working except a Gnome desktop. I did: > yum groupinstall "GNOME Desktop" and from what I can tell everything necessary is installed. However when I try to start X up I see it try and start, the display blinks as if everything is good and then drops back down to the console. The log file shown below shows a single error ([ 2665.952] (EE) AIGLX: reverting to software rendering).

Hello All, I can't get Adobe Reader to run stable on Centos7, when trying to edit settings or trying to print, it crashes. The issue is people need to digitally sign pdf forms. When I open these forms with anything else then Adobereader, I get EM To view the full contents of this document, you need a later version of the PDF viewer. You can upgrade to the latest version of Adobe Reader from www.adobe.com/products/acrobat/readstep2.html I spent a lot of time trying to solve this with other pdf viewers, including google-chrome and Foxit, and trickery with ps2pdf and Pdfedit. Nothing works. I installed Adobereader following this: https://www.if-not-true-then-false.com/2010/install-adobe-acrobat-pdf-reade… The signing of these forms is vital to my organization, so any help would be appreciated. Greetings, J.
