NTP server busted in 5.5 ?

Sun Mar 24, 2013 1:46 am

Hi All,

I'm trying to get the ntp server running under 5.5. It is installed and
running but will not respond to queries. The router has 3 LAN and one WAN
interface; no luck on any of them. The standard ntp client on the router is
configured and synced with an "outside" server. Tried the src-nat "trick" mentioned elsewhere
on the forum; didn't make any difference at all. Has anyone been able to sucessfully
run an ntp server on RouterOS 5.5?


TIA,
Reiney

that version is pretty old, try something newer, at least for me NTP-client and in turn NTP-server is working fine on 5.24 and 6.0rc12

I just set up a test system with my spare router and installed 5.24 along with the ntp package.
Still no luck; it is exhibiting the same behaviour as the other system. Is there additional
documentation for the ntp server? On a system with multiple interfaces, (and say a linux-based
ntp), there are usually configuration options to set which interfaces the server listens/responds to.

Is there anything like that for RouterOS ntp?


TIA,

Still looking for a fix for this. Appears that the MikroTik's ntp response packet is
somehow not valid:
XM.v5.5.6# ntpclient -d -h 172.16.2.3
Configuration:
-c probe_count 0
-d (debug) 1
-g goodness 0
-h hostname 172.16.2.3
-i interval 600
-l live 0
-p local_port 0
-q min_delay 800.000000
-s set_clock 0
-x cross_check 1
-n noexit 0
