Hello, looking for an answer of the following misbehaviour:
Server entries are only valid and accepted if I use ip-address and not if I
user fqdn of the timeserver1/2!
Resolving of Timeserver-fqdn is successful!
Do anybody have an explanation of this unexpected behavior?
the ntp.conf looks quite like that:
##########
restrict 0.0.0.0 mask 0.0.0.0 nomodify nopeer
##########
# driftfile ist sehr empfehlenswert wg. Reboot-Situationen

Hi
I don't really understand your ntp.conf
Ntp works with ip addresses because fqdn can sometimes map to
more than one ip address.
ntp.conf from one of my systems:

I lost ipv6 in 2012 for various reasons (network/pcs meltdown)
and not yet got it back.
