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 29 Dec '16

29 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 28 Dec '16

28 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 m.roth＠5-cent.us 27 Dec '16

27 Dec '16

Hi, folks, I know there was some talk on the list about this, but a) I'm at work, and that thread is pop-3 on my system at home, and b) what attention I paid didn't suggest *this*: Transaction Summary ================================================================================ Install 3 Packages (+10 Dependent packages) Upgrade 537 Packages Skipped (dependency problems) 278 Packages Total download size: 700 M Is this ok [y/d/N]: n One-third of the entire upgrade failed for dependencies or conflicts? I've just checked, and CR is not enabled, either. Was there a resolution for this? mark

Also, many free software developers are actually paid for their software development work. Maybe not as much as one might be paid for commercial software. Great example is postfix (free open source software), architectured, written and developed under the hood of IBM (thank you, great guys!) by brilliant person Vietse Venema Wietse Venema (I don't know where to hide in shame) Valeri (thank you, Vietse!!). > > Valeri > >> >> both are 'given' "in a world with out fences". >> >> >> -- >> >> The important thing is not to stop questioning. >> - Albert Einstein >> >> >> CentOS GNU/Linux 6.8 >> KDE 4.3.4 >> >> peace out. >> >> tc,hago. >> >> g >> . >> >> =+= >> Tired of having your microsoft os hacked? >> Change to Linux os, used by microsoft hackers. >> =+= >> If Bill Gates got a dime for every time Windows crashes... >> ...oh, wait.
