These suggestions are essentially insane because they're ignoring the basic fact that the freebsd installer creates a non-working system. If unbound requires DNSSEC, and DNSSEC requires good time, and good time requires hostname resolution, then that circular dependency is a problem that the freebsd project needs to fix, not something to be hacked around by each individual sysadmin. It is a bit disturbing to me that the project members who created this situation have been silent in the face of *months* of reporting of it by several different users. -- Ian > > On 7 June 2016 at 12:09, krad <kra...@gmail.com> wrote: > > > something as simple as this thrown in /etc/periodic/daily/ would > > probably > > do it. > > > > #!/bin/sh > > ip=`dig pool.ntp.org +short | head -1' > > cp /etc/hosts /etc/hosts.old && > > sed -e "s/.*ntp-server/$ip ntp-server/" /etc/hosts.old > > > /etc/hosts > > > > > > with these lines in rc.conf > > ntpdate_enable=yes > > ntpdate_servers="ntp-server" > > > > > > > > > > > > On 7 June 2016 at 11:43, Slawa Olhovchenkov <s...@zxy.spb.ru> wrote: > > > > > On Tue, Jun 07, 2016 at 11:35:59AM +0100, krad wrote: > > > > > > > Like i said you could configure ntpdate as well as ntpd, but > > > > give it a > > > > known good ip.
