run bash <filename> from cron
by Mark Haney 15 Nov '17

15 Nov '17

This might be a bit OT, but I've never had to do this before and what I've googled doesn't seem to be working. I have an ansible playbook that I'm working on that I want to run as a cronjob. One task I'm having trouble with is where I have a text file with lines like: rd.pl "blah blah" rd.pl "blah blah blah" This text file has to be 'executed' using 'bash filename.txt'. (Don't ask why, I'm working on code that isn't mine.) When I run the playbook in a console this bit works perfectly. However, when it's being run from cron, it dies with 'rd.pl: command not found'. My original thought is that cron's $PATH is missing the location to this rd.pl file (it's in /root/bin), so one suggestion from the Google was to add the path into /etc/crontab, but I'm still having the same problem. At this stage, I've no idea what to try next. Any ideas? For the record, this was the only option to handle the task I'm having issues with inside cron. -- Mark Haney Network Engineer at NeoNova 919-460-3330 option 1 mark.haney(a)neonova.net www.neonova.net

C6 and xfce
by m.roth＠5-cent.us 14 Nov '17

14 Nov '17

Hi, folks, So I installed xfce on my Netbook. While I was in Chicago, I worked out how to tell it to bring it up. It came up. As root. With no obvious way to tell it to show a login screen first. Did I miss something? mark

Strrange behavior of VirtualHosts in Apache (CentOS6)
by Walter H. 14 Nov '17

14 Nov '17

Hello, there is a short explanation about virtual hosts in Apache ... https://wiki.centos.org/TipsAndTricks/ApacheVhostDefault the `hostname` gives a different donmain name than what should be hosted ... e.g. `hostname` is host.example.org and the domain to be hosted is example.com, so I did this: <VirtualHost 1.2.3.4:80> ServerName host.example.org DocumentRoot /var/www/default </VirtualHost> # used to get let's encrypt for the mail server <VirtualHost 1.2.3.4:80> ServerName mail.example.org ServerAlias smtp.example.org DocumentRoot /var/www/mail </VirtualHost> <VirtualHost 1.2.3.4:80> ServerName www.example.com DocumentRoot /var/www/domain </VirtualHost> <VirtualHost 1.2.3.4:80> ServerAlias *.example.com DocumentRoot /var/www/catchall </VirtualHost> the DocumentRoot directories are empty, only in /var/www/default I have a PHP script: host.php <?php header( "Content-type: text/plain" ); printf( "Host: '%s'\n", $_SERVER['HTTP_HOST'] ); ?> now the strange behavior; http://mail.example.org/ <-- works http://smtp.example.org/ <-- doen't work http://smtp.example.org/host.php <-- gives the HTTP_HOST (PHP-script), but why? http://www.example.com/ <-- works http://hello.example.com/ <-- doesn't work http://hello.example.com/host.php <-- gives the HTTP_HOST (PHP-script), but why? doesn't work does mean, that access/errors are logged in logfile of wrong virtual host ... where is my mistake; Thanks, Walter

C6, lightweight window managers - opinions?
by m.roth＠5-cent.us 13 Nov '17

13 Nov '17

So, on my old Netbook, now happily running C6.9, I'm looking for opinions for a lightweight window manager. Gnome surely ain't it.... Years back, I used to like IceWM, but not sure it's been kept up. So, opinions? mark

Logitech Brio 4K Ultra HD Webcam - 960-001105
by Gregory P. Ennis 12 Nov '17

12 Nov '17

Everyone, I was hoping to be able to plug the Logitech Brio in and have it work, but it did not. I can have it connect to a Windows 10 laptop and have it function, so I know the camera works. The Centos 7.4 is recognizing it when I plug in the usb 3.0 cable. The results of dmesg demonstrated : [ 4519.922257] input: Logitech BRIO as /devices/pci0000:00/0000:00:04.0/0000:03:00.0/usb9/9-4/9- 4:1.4/input/input25 [ 4519.922402] hid-generic 0003:046D:085E.0009: input,hidraw0: USB HID v1.11 Device [Logitech BRIO] on usb-0000:03:00.0-4/input4 [ 4519.956452] usb 9-4: current rate 16000 is different from the runtime rate 48000 [ 4519.963948] usb 9-4: current rate 16000 is different from the runtime rate 48000 [ 4519.973798] usb 9-4: current rate 16000 is different from the runtime rate 48000 [ 4825.386775] usb 9-4: reset SuperSpeed USB device number 7 using xhci_hcd [ 5079.321074] usb 9-4: USB disconnect, device number 7 I am not seeing any new device driver in /dev/ Testing the programs 'cheese', 'vlc', and 'ucview' did not identify the camera. I have used Logitech C922 webcams with Centos 7.4 which work just by plugging them in. Does anyone have any ideas as to how to make this 4K camera work on 7.4? Thanks for your help!!! Greg Ennis

VMWare Workstation 14 on CentOS 7?
by wwp 12 Nov '17

12 Nov '17

Hello, did anybody succeed in installing/updating to VMWare Workstation 14.0.0-6661328 on an updated CentOS 7 (kernel 4.9.54-203.el7.centos.x86_64)? Here it fails at building vmmon/vmnet modules. I couldn't find anything about this on the Internet.. WS seems to get less popular and unfortunately reproduces the same inability to install upon kernel updates, that drives me nut for years now. Please don't suggest other VM sw, I'm stuck to VMWare WS at work.. Regards, -- wwp

slow libreoffice
by hw 12 Nov '17

12 Nov '17

Hi, so what do I need to install to prevent libreoffice from being so slow that it becomes unusable? This issue has been there with Fedora years ago, and now there´s same issue with Centos. Back then, there was a package you could install to make it work at normal speeds, but last time I checked, this package doesn´t exist anymore. This issue is particular to the Fedora/Centos versions of libreoffice and does not occur with other builds like the one you can download from the libreoffice web site. I was trying to make a chart and it became so slow that it´s unusable. I guess scrolling is only fast enough because I have a powerful graphics card.

home on nfs
by hw 12 Nov '17

12 Nov '17

Hi, I have the home directory of a user on an nfs server and mount it on a client. When the user logs in, they end up in the root directory rather than in their actual home directory and need to cd into it. The user can read and write to their home directory, so it kinda works fine --- but only kinda. When the user starts emacs, some of the settings in ~/.emacs are not applied, but the saved desktop is being loaded. Both machines are running Centos 7.4. What could be wrong with the nfs mount? -- "Didn't work" is an error.

CentOS 7 + NVidia Quadro 2000 graphic card
by Nicolas Kovacs 11 Nov '17

11 Nov '17

Hi, I'm currently trying to install CentOS 7 (desktop) on a Lenovo workstation with an NVidia Quadro 2000 graphical card. Normally I know my way around NVidia cards and how to configure them either using the ELRepo drivers or those downloaded from nvidia.com. I have written a corresponding article on my blog: https://blog.microlinux.fr/nvidia-centos/ But this time it looks like I have no luck. ELRepo's nvidia-detect utility detected the 'kmod-nvidia' driver, but installing it gave no result. No X. Then I tried a manual install, blacklisting nouveau, installing the necessary build tools, etc. The driver would build OK, but again, no luck, no X. Has anybody got this card to behave under RHEL/CentOS 7 ?
