NTP problem on RB493

Hardware MikroTik hardware general

I can’t get NTP client to synchronise, I’ve tried the both inbuilt and the NTP package. My config is as follows:

  • ETH1 = Public IP & default route
    ETH2= 192.168.50.0/24 with Hotspot1 & usermanager
    ETH3= 10.0.0.0/8 for management (I know a /8 is excessive but thats a whole other story :smiley: )
    ETH4= 192.168.51.0/24 with Hotspot 2 talking to a Radius server

I’ve tried a public NTP server (several in fact) and if I do a “system ntp client print” I get
enabled: yes
mode: unicast
primary-ntp: 159.148.60.2
secondary-ntp: 131.203.16.6
poll-interval: 16s
active-server: 131.203.16.6
I’ve never got the clock to adjust with the result that after a reboot it goes back to the BIOS time killing usermanager users that are set to specific dates etc.
I’ve tried external i.e. public IP, NTP servers and can ping them but the NTP fails with the status always as “Started”. If I point to an internal (10.0.1.2) NTP server the status changes to “reached” and stays that way (way past the approximately 30s stated in the manual)
I’m currently running 3.19
Any ideas? Is there a firewall rule I need to enable?
Cheers

WTF??
Added NTP package again & rebooted -no diff with either internal or external NTP servers, disabled package & rebooted and now can access the internal NTP server…
Go figure, must have been cos I threatened it with a forum posting…

there are two NTP implementations in RouterOS. Simple NTP is included in RouterOS by default. the normal NTP package comes separately and requires installation, it has more features and also a server.

It looks like you had trouble with the regular NTP package, and when you disabled it, and started to use simple NTP, it worked. If yes, we need to test them both, maybe there is a problem.

I did start off with the NTP package as I was going to use it for a NTP server for our wireless network (RoamAD based) which was having issues with connecting to our NTP server but as this post shows could not get it going despite moving to the simple NTP. Basically sequence was:

  • NTP package installed with initial OS install
    Public & Private NTP server not working
    Disable NTP package
    Use Simple NTP
    Public & Private NTP server not working
    Enable NTP package
    Public & Private NTP server not working
    Disable NTP package & NTP scheduled to uninstall
    Use simple NTP
    Public NTP Server didn’t work
    Change to Private IP NTP server which worked
