Check NTP port opened

[khalil]

Hello
How to check the NTP port open or not in the LM?

[admin]

Use this test script:

Code:

12

res = io.readproc('ntpd -dnq -p 0.europe.pool.ntp.org 2>&1') log(res)

NTP uses UDP port 123, check that it's not blocked on the firewall/router.

Thanks admin
if Port opened I should get something like this:

Code:

12345

* string: ntpd: '0.europe.pool.ntp.org' is 194.58.200.20 ntpd: sending query to 194.58.200.20 ntpd: reply from 194.58.200.20: offset:-0.009966 delay:0.108452 status:0x24 strat:1 refid:0x00535050 rootdelay:0.000000 reach:0x01 ntpd: sending query to 194.58.200.20 ntpd: reply from 194.58.200.20: offset:-0.009715 delay:0.107909 status:0x24 strat:1 refid:0x00535050 rootdelay:0.000000 reach:0x03

Yes, this is a correct response when NTP server can be reached.
