That's chronyc translating the IP addresses to names and DNS not responding quickly enough. Use "chronyc -n" to avoid DNS lookups. > >Delaying start of chronyd until network is probably a better idea. > > Any ideas on exactly how to do this?

I'm not sure what's the best way to do this on Debian, it will depend on the networking service/manager. With dhclient, it should be possible to (re)start chronyd from a hook script, see the dhclient-script(8) man page. > >You could also try cleaning /etc/resolv.conf before chronyd is > >started, so it would keep trying resolving until the DHCP client > >starts and rewrites the file. > > Again, how exactly would I "clean" /etc/resolv.conf ?

That would possibly change the resolver's failure from permanent to temporary and chronyd would try again. -- Miroslav Lichvar -- To unsubscribe email chrony-users-requ...@chrony.tuxfamily.org with "unsubscribe" in the subject.
