Instale un server ntp con Centos 5 y tengo las
siguientes dudas.
Primero esta es mi
configuracion.
# Permit time synchronization
with our time source, but do not
# permit the source to query or modify
the service on this system.
restrict default kod nomodify notrap nopeer
noquery
restrict -6 default kod nomodify notrap nopeer noquery
# Permit all access over the loopback interface. This could
# be
tightened as well, but to do so would effect some of
# the administrative
functions.
restrict 127.0.0.1
restrict -6 ::1
# Hosts on
local network are less restricted.
#restrict 192.168.1.0 mask

1ero: No puedo acceder desde mi red
(172.19.194.0/24) a este servidor ntp me da acceso denegado y no tengo
filtraje en este servidor. El servicio ntpd esta trabajando osea que no se
por que no me deja entrar.
2do: Actualizo bien
con los servidores ntp que les tengo declarado pero siempre con una hora de
diferencia ya sea con America/Havana o con Cuba provando le puse
America/Jamaica y me dio bien. Como puedo conseguir una definicion actual de
la zona Cuba o como podria cambiarla para que refleje un horario actual de
nosotros.
En espera de sus respuestas.
