Nux VLC gives CLI only on CentOS-6.x
by Scott Robbins 18 Sep '15

18 Sep '15

I thought this was just because of various unwise repo mixing that I'd done on my main home server-cum-workstation, but I've been able to duplicate it on a fresh VirtualBox installation. I install the nux repo vlc-core and vlc-extras. I then try to start it from a command line. I get +++++++ main interface error: no suitable interface module [0x1ae5108] main libvlc error: interface "globalhotkeys,none" initialization failed [0x1ae5108] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. [0x1bac2b8] [cli] lua interface: Listening on host "*console". VLC media player 2.0.8 Twoflower Command Line Interface initialized. Type `help' for help. +++++++ I can open any media file with it, but I can't get the usual GUI interface. I tend to use mplayer and smplayer more often, but I've not been able to find the reason for this not working. Googling has brought me some Ubuntu issues that were resolved with reinstalling, but the only thing I've seen with CentOS-6.x and this is a few years old. Does anyone else have this issue? I use openbox or dwm on the machines, I'm not sure if that's part of the issue. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6

Does anyone know of a source of edac labels? The one that gets installed is tiny, and doesn't for example, have anything for Dell. mark

Re: [CentOS] Is ATRPMs dead?

Thanks to Earl for the NUX repo recommendation. Good VLC and ffmpeg versions (for CentOS) here. From what i can tell, atrpms died a death earlier this year or the end of last cheers - cal sawyer Earl A Ramirez <earlaramirez(a)gmail.com> wrote: To: CentOS mailing list <centos(a)centos.org> Subject: Re: [CentOS] Is ATRPMs dead?

Re: [CentOS] Centos 7 using cups with cups-lpd loaded getting print jobs from an Sco Unix lpd system
by Shawn Parks - CMAC 17 Sep '15

17 Sep '15

Centos users, I new to Centos 7 and my problem is the following: I am using my Centos 7 system as a print server in a warehouse. Using cups for the print queue's. Which I can print to the printers find from the Centos 7 machine. The hosting system is Sco Unix using lpd printing. This machine is in Illinois and the warehouse / Centos 7 machine is in Arizona. I have loaded "cups-lpd" using yum and it seems fine. I have also setup "/etc/xinetd.d/cups-lpd" Following is a "netstat -tanp |grep -i listen" tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1090/sshd tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN 1096/cupsd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1671/master tcp6 0 0 :::515 :::* LISTEN 1095/xinetd tcp6 0 0 :::22 :::* LISTEN 1090/sshd tcp6 0 0 :::631 :::* LISTEN 1096/cupsd tcp6 0 0 ::1:25 :::* LISTEN 1671/master I notice that "port 515" is only listening on tcp6 not tcp. Question: could this be my problem? and how can I get "port 515" to be listened to on tcp? my Sco Unix print queue "status" file says "waiting for gate to come up". I have had the local hardware person verify that the router is "port forwarding" port 515 to my Centos 7 system. Help in this matter would be greatly appreciated. Thanks, Shawn

Secure boot
by Gordon Messmer 17 Sep '15

17 Sep '15

After updates to grub2 and kernel in CentOS 7, today, systems will no longer boot in Secure Boot mode. I'm not positive, but I think grub2 is the culprit. Is anyone else seeing the same problem?

gpg decryption error from only 1 user
by Dustin Kempter 17 Sep '15

17 Sep '15

Hi all, I am having an issue. We have a vm that has encrypted data with gpg. The vm is centos 6.5 and it has multiple users. user1=bob user2=kevin user3= postgres user4=root. Only postgres has access to the file in which we keep the encrypted data. I as root will su - postgres, cd that data dir, and use this command "gpg -d (file_name)" and it works just fine. However the user1 "bob" will sudo su - postgres (have an entry in sudoers file to allow) and become postgres, cd to the dir with the data, run this same command "gpg -d (file_name) however it gives this error gpg: CAST5 encrypted data can't connect to `/home/postgres/.gnupg/S.gpg-agent': No such file or directory gpg-agent[6153]: command get_passphrase failed: Operation cancelled gpg: cancelled by user gpg: encrypted with 1 passphrase gpg: decryption failed: No secret key I really do not understand whats going on here. I have tried deleting the user bob, and re creating it in case of some sort of corruption but still the same issue. We also see an issue where I installed screen. as any user but bob I can create or join. But as bob I get this error "Cannot open your terminal '/dev/pts/2' - please check."Also I, as superuser did this su - bob sudo su - postgres cd data dir gpg -d (file_name) works with no issues, please help me debug this I am out of ideas. thanks in advance

Centos 7, systemd, and nvidia drivers
by m.roth＠5-cent.us 17 Sep '15

17 Sep '15

Or, another rant against systemd. Moderators, put up with it - this is an issue. I tried systemctl start multi-user.target. I tried systemctl stop graphical.target. I finally had to set the multi-user.target as the default, and reboot, to get rid of the nouveau drivers. Note that I tried to modprobe -r, and rmmod with all the modules using nouveau, and couldn't - I kept getting "in use" - it seemed like a circular reference. As I said, I rebooted. Then I ran the proprietary build, ran fine. I try starting the graphical target, no joy. I changed the default target back to graphical, and rebooted. Still no xorg. Googling (yahooing?), I added rdblacklist=nouveau in grub.conf, *then* had to rebuild the grub2 (grub2 must *die*). Still wouldn't see the nvidia drivers on reboot. Finally, I rebuild the initramfs, which got the now-built and installed nvidia drivers (and I'd yum uninstalled nouveau), and finally, it came up. Oh, and for some reason, without the reboot, the Xorg.0.log wasn't renewed, as though it hadn't actually restarted X. Plus, it appears that <ctrl-alt-bkspc> is disabled.... Then all I had to do was fight and hand-edit the xorg.conf, which *MUST* be in /etc/X11/sorg.conf.d to be even seen.... But what I had to do is beyond this - my user's got three monitors, on two cards, and two are for 3D, and so nothing to do with my issues with trying to get systemd to load and xorg to use the nvidia drivers. mark, incredibly frustrated

(?) Mailman VERY slow with IPv6 (with work-around)
by Jay Leafey 17 Sep '15

17 Sep '15

I recently stood up an EL7 box with Mailman for a few lists I run for some friends. My old install, on an EL6 system, ran with no issues for several years but I was induced to upgrade by a "hardware casualty" on the old system. I was going to have to rebuild anyway, so why not take it as an opportunity to try EL7? The build went fine and I was able to migrate the lists over with no issues, but once I got there just about everything to do with Mailman operations were painfully slow. For example, "list_lists" took 5 seconds of "real" time. I was used to it taking _much_ less as I only have about 6 lists. This affected both the command-line Mailman tools and the web interface. My first inclination was to blame Python, but other code executed just fine with it. While testing I tried an strace of list_lists and found that it was timing out on a read operation to a socket to the Avahi daemon (/var/run/avahi-daemon/socket) while trying to resolve the link-local IPv6 address. Having flashbacks to Sendmail stalling on DNS issues I decided to try fixing resolution first. As a test I put the link-local address into my /etc/hosts file with a localized name. Running list_lists then took about 0.19 seconds "real" time! The web interface also changed from painfully slow to it's previous behaviour on EL6. I imagine just turning off IPv6 would work as well, but I have an actual use case that is a lot easier with it turned on. I don't know if anybody else has seen this, but thought it might be handy for someone else. -- Jay Leafey - Memphis, TN jay.leafey(a)mindless.com

CentOS-6 - LogWatch Cyrus-IMAPD script was CentOS-6 - LogWatch

Given I know little or nothing of Perl beyond the bare fact of its existence no doubt there are better ways to get the results I obtained. But this is tested on CentOS-6 with cyrus-imapd.2.3.16-13.el6_6, It only handles IMAP logins so anyone using POP3 or Sieve needs to add there own code for those.

Periodic speed test
by Timothy Murphy 17 Sep '15

17 Sep '15

I run the speedtest from <https://pypi.python.org/pypi/speedtest-cli/> quite often, and find it very reliable. I'm wondering if anyone has developed a version to run the speed test at regular intervals, say every 6 hours, and record the results in a simple database or just a file? I imagine it would be a fairly easy task to modify the Python code to do this, but it would be even easier if someone has already done it! -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin
