CentOS 7 User Manager Tool
by Igal ＠ getRailo.org 11 Oct '14

11 Oct '14

I have CentOS 7 installed with GUI (Gnome 3.8.4) and I'm trying to follow the guide at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/ht… it speaks of "System > Administration" from the GUI or "system-config-users" from the command line, but I can't find either? I don't have a "System" top menu, only "Applications" and "Places", and when I try the command line option I get "command not found". any ideas? TIA! -- Igal Sapir Railo Core Developer http://getRailo.org/

Linux on an ancient Macintosh G5?
by dan stoicheff 11 Oct '14

11 Oct '14

Has anyone experienced the conversion of the aluminum chassis Mac G5 to a Linux box? Curious in Pennsylvania. I need to obtain the power cable somewhere to try it. It is a 64-bit monster, so seems like it is worth trying if I can find the weird cable it needs. No luck to date regarding the cable. Thanks. The Bears will never win until number six leaves.

答复: CentOS 7 docs, tutorials, etc...
by 沈焕标 11 Oct '14

Perhaps RHEL/CentOS 7 are something different, however, they just change a little, their base used are similar. On a gnome desktop, if you want to add a shortcut to the desktop, you can reference xxx.desktop in /usr/share/application/ , than write some similar xxx. desktop which you prefer and cp to the desktop directory ， it's really useful.. ------------------------ Best wishes ----------- ---------------Bill Shen ------------------------ ________________________________ 发件人: Igal @ getRailo.org<mailto:igal@getrailo.org> 发送时间: ‎2014/‎10/‎11 2:52 收件人: CentOS mailing list<mailto:centos@centos.org> 主题: Re: [CentOS] CentOS 7 docs, tutorials, etc...

I installed CentOS 7 with GUI so I have Gnome 3.8.4 which I expected, but how come I have KDE stuff there as well? and... I still haven't figured out how to add shortcuts to the desktop and/or task bar which should really be a context menu option so I'm not sure why Gnome is so un-intuitive in that case.

Centos 7 and ntp
by Frank Cox 11 Oct '14

11 Oct '14

I've curious about where and how Centos 7 gets its ntp configuration from. When I installed the operating system, I went through this page and told it to use "network time", as shown: http://media.if-not-true-then-false.com/2014/07/06-centos-7-date-and-time-7… I just discovered that i don't actually have ntp installed on this computer, though the rpm does exist when I search for it with yum. I do have ntpdate installed, but can't find any configuration files that specify the timeservers that it's supposed to be using. I don't have a /etc/ntp.conf file, and a grep of /var/log/messages doesn't yield any lines containing the string ntp either. My computer's clock is not inaccurate, so I guess that ntp is working somewhere behind the scenes here, but it sure is well hidden. Where is ntp and its configuration hiding? Why isn't it logging what it's doing? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

The magic is more about ConsoleKit and PolicyKit than specifically systemd but the underlying dbus gunk seems to be merging together. -- Les Mikesell lesmikesell(a)gmail.com

Wrong file permissions in CentOS 7
by Alan Stern 10 Oct '14

10 Oct '14

Sorry if this question has been asked many times before. On a new CentOS 7 system, when I create files they end up with strange permissions. For example, as root: [root@server ~]# umask 0000 [root@server ~]# touch a [root@server ~]# ls -l a -r--r----- 1 root root 0 Oct 10 11:45 a As a regular user: [stern@server ~]$ umask 0000 [stern@server ~]$ touch b [stern@server ~]$ ls -l b -rw------- 1 stern stern 0 Oct 10 11:47 b In both cases the permsissions should have been -rw-rw-rw-. What on earth is going on, and how can I fix it? Thanks, Alan Stern

redhat-lsb
by Les Mikesell 10 Oct '14

10 Oct '14

I've noticed that some systems don't have redhat-lsb or even redhat-lsb-core installed and as a side effect, the ocsinventory agent reports them as 'linux' instead of Centos with the release version. Also, where it is installed and ocsinventory does pick up the name, it doesn't include Centos (pre-7.x) in the 'all Linux' grouping because the name is just CentOS and unlike 'Red Hat Enterprise Linux, or 'SUSE Linux Enterprise Server' which include Linux in the name. Anyway, a few questions: Is there some reason to omit redhat-lsb-core from any of the install groups? Why is there such a big list of dependencies? (glibc-devel, gdbm-devel, perl-CGI, etc., seem odd as 'standard requirements'). Even more so for the full redhat-lsb package? Why are things like qt and ghostscript pulled in by dependencies? -- Les Mikesell lesmikesell(a)gmail.com

CentOS 7 docs, tutorials, etc...
by Igal ＠ getRailo.org 10 Oct '14

10 Oct '14

hi all, after many years of working almost exclusively with Windows servers I am trying to switch to CentOS. I have a couple of books which were written for CentOS 5, but many (basic) things do not apply to CentOS 7 anymore, which is very confusing. Internet resources suffer from the same problem. for example, one of the books shows a Services configuration tool, which should be accessible from System > Administration > Server > Services, but I don't even have a System top menu anymore. the closest thing I have is Applications > System Tools but there is no Services applet there. also, I am trying to set some shortcuts to the Desktop, and preferably pin them to the Taskbar if such an option exists, but in vain. using Gnome 3.8.4 BTW. any ideas? advice? TIA!
