similar to: startup process that rebuilds aliases.db?

HI, All our unix boxes under puppet are configured with the ''mailalias'' resource type as in : mailalias { "root": recipient => "linuxroot@fqdn", ensure => present } The majority of those boxes however don''t have /etc/aliases served out by puppet, rather, they simply have the installed default /etc/aliases locally.

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

AFAIK the only thing needed to make your host an NTP server using chrony is to set the allow line to the network address in CIDR format of the network you want to be served, and uncomment it. The restart chronyd. You also need to ensure that port 123 (NTP) is open to your internal network on your filrewall. I have a CentOS 6 box that is an NTP server for my network. CentOS 7 works the same

Hi, As Centos 7 and Fedora defaults to chronyd [2] , should I use ntpd for some reason [3] ? I based my configurations on [1] which use ntpd ... but I thinking change for chronyd , change ntp deamons could outage the samba service and client computers ? Thanks [1] https://negativo17.org/samba-4-active-directory-with-bind-dlz-zones-dynamic-dns-updates-windows-static-rpc-2/ [2]

Hi All, Just noticed a funny time jump on a testing CentOS 7 VM. Specifically the system time jumps around by a few hours during system boot. The below is a selection from /var/log/messages during boot: Jan 19 12:49:57 arr-data-dev chronyd[716]: Frequency -0.829 +/- 0.007 ppm read from /var/lib/chrony/drift Jan 19 12:49:57 arr-data-dev polkitd[720]: Started polkitd version 0.112 Jan 19

So I have learned that Postfix should delay until Chronyd has moved the system time from 0 to current. What other services need to be delayed? Apache? Bind? Of course if this is a nameserver, Chronyd will probably not be able to resolve the NTP server addresses until Bind is running! thanks

I have read: http://thegeekdiary.com/centos-rhel-7-chrony-vs-ntp-differences-between-ntpd-and-chronyd/ My server is up all the time and will serve time to internal systems (via DHCP options). Caveat is that my server is an armv7 (Cubieboard2) which does not have an RTC (no battery). So whenever the system boots, the time is ZERO (Dec 31, 1969 or some such). Chrony fixes this really fast;

Hi, the instructions for "Time Synchronisation - SELinux Labeling and Policy" on https://wiki.samba.org/index.php/Time_Synchronisation_-_SELinux_Labeling_and_Policy don't seem to work on CentOS 8. Using chrony I tried to adapt them (with very limited SELinux knowledge) like this: chcon -u system_u -t chronyd_exec_t /var/lib/samba/ntp_signd semanage fcontext -a -t chronyd_exec_t

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-ntpd-and-chronyd/ Essentially, chrony is more for laptops with intermittant network connections, and ntpd is better suited to

I just happened to notice this morning in /var/log/messages: chronyd[1299]: Selected source 207.244.103.95 host 207.244.103.95 95.103.244.207.in-addr.arpa domain name pointer dns-e.wdc-us.hosts.301-moved.de. Just curious why my machine in Indiana (USA) is asking for time in Germany. Wouldn't it use something closer ? Thanks, jerry
