Property Description
broadcast ( yes | no ; default: no ) - whether NTP broadcast message is sent to 255.255.255.255
every 64s
enabled ( yes | no ; default: no ) - whether the NTP server is enabled
manycast ( yes | no ; default: yes ) - whether NTP server listens for multicast messages sent to
239.192.1.1 and responds to them
multicast ( yes | no ; default: no ) - whether NTP multicast message is sent to 224.0.1.1 every 64s
Notes
NTP server activities only when local NTP client is in synchronized or using-local-clock mode.
If NTP server is disabled, all NTP requests are ignored.
If NTP server is enabled, all individual time requests are answered.
CAUTION! Using broadcast, multicast and manycast modes is dangerous! Intruder (or simple
user) can set up his own NTP server. If this new server will be chosen as time source for your
server, it will be possible for this user to change time on your server at his will.
Example
To enable NTP server to answer unicast requests only:
[admin@MikroTik] system ntp server> set manycast=no enabled=yes
[admin@MikroTik] system ntp server> print
enabled: yes
broadcast: no
multicast: no
manycast: no
[admin@MikroTik] system ntp server>
Time Zone
Home menu level: /system clock
Notes
NTP changes local clock to UTC (GMT) time by default.
Example
Time zone is specified as a difference between local time and GMT time. For example, if GMT
time is 10:24:40, but correct local time is 12:24:40, then time-zone has to be set to +2 hour:
[admin@MikroTik] system clock> print
time: dec/24/2003 10:24:40
time-zone: +00:00
[admin@MikroTik] system clock> set time-zone=+02:00
[admin@MikroTik] system clock> print
time: dec/24/2003 12:24:42
time-zone: +02:00
[admin@MikroTik] system clock>
