I just checked the forum and noone had a similar topic, so I decided to open one. I have a RB411U which I upgraded from 5.17 i think to 5.21. Then I noticed that there is no NTP client and installed one by downloading it from mikrotik’s site and placing the package in the files folder. After the reboot in system there is NTP client and server and I see the NTP package in system->packages as enabled, but it is not part of the routeos-misbe branch (I guess this is normal, as it was added manually later).
I enabled debugging on NTP using:
/system logging add topics=ntp,debug
However in the Log file there is no actity of the NTP client. I also tried at least 10 different NTP servers without any success.
The only difference is that after restart the sysdate of the router is Jan/01/2002 and before it was ../../1970.
I don’t think the ISP blocks NTP traffic having in mind that my log is empty and I don’t see any NTP client activity.
As I understand it, the NTP package is an NTP server. The NTP client is still under “/ system ntp” in the console, or “System > SNTP Client” in winbox.
NTP package is NTP client and NTP server. without that package (integrated into system) is SNTP client (simple ntp) that is not that precise as NTP client in ntp package. When you install ntp package there is no reason to keep SNMP client active as it will not be able to set time precise enough for NTP server to run. (there are strict stratum requirements for NTP server to run)
I have a situation where my network (Network 1) is made up of 3 RouterOS (Router A, B, C - all with NTP Package) and various Windows servers and clients. Router C is connected to a vendor network (Network 2) with what I was told is an NTP server (ExtTimeServer). It seems that Router C will connect to the ExtTimeServer server but will not synchronize.
It never changes from status: reached to status: syncrhonized.
I also ran packet sniffer and it shows NTP Version 4 from Router C (192.168.17.101) and NTP Version 3 from ExtTimeServer (192.168.17.1)
I then configured Router C (10.0.3.102) to look at Router B (10.0.3.251) for NTP. Router C immediately synchronized.
From what I have read NTP Version 3 and 4 should be compatible? Is it possible the ExtTimeServer uses SNTP?
If so, am I correct in assuming you cannot use an SNTP time server to set RouterOS time that has NTP package installed?
