chronyd configuration as a local ntp server
by Phil Amy 30 Dec '16

30 Dec '16

Robert, If your NTP server will be on 7/24, I would uninstall chrony and install ntpd which is still included in CentOS 7. Configure as usual. For the differences between chrony and ntpd reference: http://thegeekdiary.com/centos-rhel-7-chrony-vs-ntp-differences-between-ntp… Essentially, chrony is more for laptops with intermittant network connections, and ntpd is better suited to always-on servers

php-fpm user other than webserver user?
by Matthias Leopold 29 Dec '16

29 Dec '16

Hi, I don't really know where to post this, i'll try here since i use both CentOS and RHEL... I'd like to know how others handle the setup of Apache httpd and PHP-FPM when the PHP-FPM user is different from the webserver user. This is the case in the default configuration of IUS PHP-FPM packages (not in stock CentOS/RHEL). So I have httpd running as 'apache' and PHP running as 'php-fpm'. I'm aware of special use cases where a configurable PHP user is a nice feature, but how do i handle filesystem setup for this default configuration in a pretty and secure way? Do people use it like that or do they change PHP-FPM user back to 'apache' (like in RH packages)? All of the setups i tried (eg. using ACLs) don't really look "pretty" and "robust", something I'd like to have when using "default" configurations. I hope I'm not thinking too complicated... Thanks for feedback matthias

C7 Mate - files suddenly moved back onto desktop
by Frank Cox 29 Dec '16

29 Dec '16

My wife sometimes puts files on her desktop to work with them, then cut-and-pastes the file to put it into a folder when she's done. This morning she has seven files on her desktop that she has worked on over the course of the past week. They have suddenly, overnight, moved out of the folders that she had put them into and moved onto her desktop! They are no longer in the folders that she put them into. I told her to log out and log back in since I'm guessing that the Caja file manager may be somehow at fault. Does anyone have any ideas about what else it could be? Some kind of cross-linking on her hard drive? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

Centos7.3-Mate
by johan.vermeulen7＠telenet.be 29 Dec '16

29 Dec '16

Hello All, I have this problem starting Centos7.3 - the official name escapes me at the moment. I often install Centos7 Minimal, then X Window System, then Mate desktop. This last step gives me trouble, and I have to run # yum groupinstall mate --skip-broken output: skipped packages: NetworkManager-I2tp ldns libreswan unbound-libs xl2tpd I realise this is probably an issue for EPEL or Mate. Happy hollidays J.

CentOS 7 and systemd: SysV initscript: how detect boot vs. interactive use?
by whitivery 28 Dec '16

28 Dec '16

Moving from CentOS 5 to CentOS 7, discovered that a test in a SysV initscript for whether it is running interactively, instead of at boot time, no longer works. Under CentOS 7 / systemd, is there some way for the initscript to know this?

GRE based attack?
by Robert Moskowitz 28 Dec '16

28 Dec '16

My new Centso7 server that I am testing out is connected with a public address on my dmz. I am connected to the console port. Overnight the following message was logged to the console: [44133.679108] conntrack: generic helper won't handle protocol 47. Please consider loading the specific helper module. Protocol 47 is GRE. So was this 'just' an a ping by an attacker? No one, but I have any business on this server. Well other than the files I put up for people. thanks

Can anyone confirm that the above 4-port card is supported at its full resolution and capabilities under CentOS 6 and/or 7? The card has four DisplayPort 1.2 connectors, each capable of driving a 4K monitor. Thank you.

chronyd configuration as a local ntp server
by Robert Moskowitz 27 Dec '16

27 Dec '16

This is for centos 7 that has chronyd 2.1.1 I am looking into how to use chronyd as my local ntp server. On my old servers with ntpd I had local access control lines like: restrict 192.168.128.0 mask 255.255.255.0 nomodify notrap But in looking for documentation on chronyd I did not find anything on this at: https://chrony.tuxfamily.org/doc/2.1/manual.html In the actual /etc/chronyd.conf there is the sample line: # Allow NTP client access from local network. #allow 192.168/16 Does this allow only allow queries? Does chronyd support the 'restrict' option? thank you

GUI black screen on login, startx works???
by Dave Burns 27 Dec '16

27 Dec '16

Hello, I'm using a recent install of centos 7, no GUI customizations that I recall. When I log in using the GUI it accepts my password and the mouse appears on a black screen, like it is preparing the desktop, but the desktop never appears. If I hit control-alt-f4 and log in using the command line, and then execute startx, Everything seems to work perfectly. What sort of troubleshooting should I do to figure out what is stalling? I'm not at all familiar with this aspect of things. thanks, Dave

by lejeczek 27 Dec '16

27 Dec '16

hi everyone just a quickie to devel maybe. I'm looking at some bits: devtoolset-4-elfutils-libelf-0.163-2.el7.x86_64 VS elfutils-0.166-2.el7.x86_64 isn't devtool ageing? Could this be the case with more packages? regards, L.
