My machine has a static IP, with dhcp and IPv6 disabled. Every time I reboot, some process rewrites /etc/resolv.conf, including a comment about dhcpclient. The only package I have installed that shows up in "rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in there is named dhcpclient. I'd like to figure out what software is rewriting this file and why. man 5

Hai Viktor, I've seen some answers already and all are correct. What i would do different here, when running in a container.. apt-get remove --purge ntpd ;-) The hosts that are running AD DC containers these need all up to use the same time source. And you dont install ntpd, you still have the same time in you AD. NTPD is not obligated to setup AD DC's. Its obligated to have

Hi On 5.3 i have a situation where some boxes have been 3 or 4 seconds out and restarting ntpd has fixed the issue. What i dont understand is why the clocks did not drift to the correct time when the config seems correct in that restarting ntp did correct the time. Is there something 'special' i need to do in order for the drift to work? $ cat /etc/ntp.conf restrict default

Hi Louis, In general, this sounds like the solution I was looking for. But I’m still a bit unclear about the practical implementation. So, the DC can be setup without ntpd as it will work based on the system clock which, in turn, is actually being updated by the container host using NTP. Which means we’ve got the DC itself covered. But if ntpd is not installed, then how can the DC serve time

Hello, I recently compiled Samba 4.0.6 (as an AD DC) and am running it on Ubuntu 12.04. I followed the instructions on the Samba wiki (https://wiki.samba.org/index.php/Configure_NTP) for how to configure ntp, however the domain clients are rejecting the DCs as being acceptable time sources. Below is my ntp.conf: server 127.127.1.0 fudge 127.127.1.0 stratum 10 server 0.pool.ntp.org iburst

Hello all, After reboot, one of my servers running CentOS5 no longer keeps its clock synced automatically. ntpd is running and I don't see anything weird being logged. If I kick off ntpd with 'ntpd -q', it will sync the clock. However, if I just rely on ntpd started with 'service ntpd start', syncing does not happen. I previously had: # Undisciplined Local Clock. This

What Marco and Robert already did say.   This is what i mean ( and Robert ). Marco's option to disable though kernel is also an option.   Maybe a bit cryptic but like this.   HOST              - CONTAINER - SambaDC- samba-AD distibuting time to PC's. ||                         ||| HOST_its_NTP_Service  => get Internet time  |||| OTHERHOSTS NTP Client - COINTAINER - SambaMember  -

I’m currently trying to install a new (primary) AD DC in a Linux container. It seems to me that being in a container, the DC is easier to maintain and backup than on bare metal, and I prefer a container over a VM for performance reasons. If the container setup will prove to be too much of hassle, I’ll switch to a VM, though. The first issue I’m facing is time synchronization. An container cannot

Hello, I have a question regarding signed NTP support for Samba4 on Ubuntu 12.04. I have followed most of the steps outlined here: https://wiki.samba.org/index.php/Configure_NTP These steps I did differently are: * I did not install from source because the latest Ubuntu package for ntp available on Ubuntu 12.04 includes ntp-signd support already * I did not install Samba4 to /usr/local/samba, so

It seems that the prominent North American Enterprise Linux vendor has decided that dhclient.conf should be ignored, i.e. ifup-eth causes dhclient to be called with "-cf /etc/dhclient-$(DEVICE).conf", and then ifup-eth/ifdown-eth wipes the file out each time. Through the use of "DHCP_HOSTNAME" in ifcfg-eth0 you can specify a host name, but because of the above behavior of
