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!

As a computer person of nearly 50 years experience (wish I was 20 again), I have long recognised the essential fact .... * That if one gets it Right the first time, one inevitably saves an awful lot of time and an awful lot of effort subsequently trying to get it Right or even to "improve" the less than perfect item. A little critical and constructive effort into the architecture and functionality of systemd would have brought considerable benefit. Perhaps the Fedora and RedHat persons might remember this advice when the next "wonder" is proposed. No reason not to want *genuine* perfection for all. -- Regards, Paul. England, EU.

named log entries - Are any of these a problem?
by Bill Gee 10 Oct '14

10 Oct '14

Hello everyone - I run bind version 9.8.2 on CentOS 6.5. The daily logwatch run sends me the following items. Are any of these a real problem? ============ checkhints: extra NS 'A.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'B.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'C.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'D.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'E.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'F.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'G.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'H.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'I.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'J.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'K.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'L.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: extra NS 'M.ROOT-SERVERS.NET' in hints: 170 Time(s) checkhints: unable to find root NS 'ns1.dnslibre.info' in hints: 147 Time(s) checkhints: unable to find root NS 'ns1.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns10.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns2.dnslibre.info' in hints: 147 Time(s) checkhints: unable to find root NS 'ns2.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns3.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns4.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns5.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns6.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns7.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns8.opennic.glue' in hints: 170 Time(s) checkhints: unable to find root NS 'ns9.opennic.glue' in hints: 147 Time(s) clients-per-query decreased to 10: 2 Time(s) (repeated many time with various numbers) =================== The hints file DOES contain two entries for each of the ROOT-SERVERS. One is the ipv4 address and the other is the ipv6 address. I use the hints file downloaded from http://www.internic.net/domain/named.root . The hints file does NOT contain any entries for the opennic.glue or dnslibre.info servers. However, when I run "rndc -all", the output shows that bind has entries for those servers. The names will resolve and answer ping. I searched all over trying to find information on the clients-per-query setting. My named.conf file does not contain an entry for clients-per-query. Is there some detailed documentation on this setting? What does it really do? Three more notes: 1) I see no problems in daily operation. All web browsing works as does resolution for local machines. 2) This bind server does not get queries from outside my local network. 3) I use OpenNIC as the "forwarders" servers. I used to use OpenDNS until they stopped handling Yahoo email correctly. Thanks - Bill Gee

file system replication
by Jason T. Slack-Moehrle 10 Oct '14

10 Oct '14

Hi Everyone, I need to keep 2 systems identical. Mostly e-mail directories, web directories, mysql, etc. The goal here is to have a 2nd system ready to go it the first one starts to exhibit hardware issues. What are options to have this happen? I'm going out on a limb and thinking rsync but I haven't used it past just simple use cases. Can anyone provide some insight for me? CentOS 6.5. Jason

Instead of just taking the wiki instance down during that maintenance, we've decided to relocate it to a temporary host, proceed to maintenance, and then migrate it back to the previous node. Migration is scheduled for Friday October 10th, 11:00 am UTC time. You can convert to local time with $(date -d '2014-10-10 11:00 UTC') Migration will happen in several steps: 1 - we "freeze" the wiki on the actual node, transfer data, update the A record, restore the service on the temporary node (disruption ~ 30min) 2 - we proceed to the needed maintenance on first node (no disruption in service, but no estimated time) 3 - depending on time needed for step [2], and assuming we have no hardware issue, we proceed like step [1], but in reverse (so disruption ~30 minutes again) Thanks for your comprehending and patience. on behalf of the Infra team, - -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iEYEARECAAYFAlQ2g0kACgkQnVkHo1a+xU4flACfc1IjPeHelBntwt4eNTd6SBvM wXAAnAqtOg4Ko4nqd0QVUfX7ZcQevD5K =v15z -----END PGP SIGNATURE----- ------------------------------ _______________________________________________ CentOS-announce mailing list CentOS-announce(a)centos.org http://lists.centos.org/mailman/listinfo/centos-announce End of CentOS-announce Digest, Vol 116, Issue 6 ***********************************************
