Setting Time

[wifiwizard]

Hello,

First time Netonix switch user here and having some issue setting the NTP server so I can have accurate time on the log. I've enabled NTP and set a know good NTP server and set the timezone. As you can see below:



In the log it just shows it trying to connect to the NTP server over and over. What am I doing wrong? Thanks.

Can the switch resolve the DNS name and/or reach the default gateway?

[wifiwizard]

I can ping the default gateway from the switch. How should I check to see if it can resolve the DNS name?

Code: Select all

ws12# cmdline

BusyBox v1.19.4 (2017-03-07 13:42:37 EST) built-in shell (ash)
Enter 'help' for a list of built-in commands.
admin@ws12:/www# nslookup google.com
Server: 208.67.222.222
Address 1: 208.67.222.222 resolver1.opendns.com
Name: google.com
Address 1: 2607:f8b0:4002:808::200e
Address 2: 172.217.2.46 atl14s78-in-f14.1e100.net
admin@ws12:/www#


You must set the DNS server(s) in the Device -> Configuration tab

Ping works too.

So I can ping out from the Netonix just fine. I've changed the NTP server to a new server just in case (time.google.com). Still no time on the switch. Any other ideas?

Also the switch is in DHCP mode so I cannot set DNS manually. So I guess somehow the switch isn't getting DNS so it cannot resolve the hostname? Is there a way to manually set the DNS servers?

So why put in time.google.com simply put in the known IP address which will tell you if it is a DNS issue

time.google.com = 216.239.35.0

ALSO PLEASE UPLOAD IMAGES USING THE INSTRUCTIONS IN MY FOOTER

Yes, adjust your dhcpd.conf on your DNS server.
However I cannot think of a good reason to let a switch, router, etc use a DHCP acquired address. Bad practice IMHO as it could change...

I was not suggesting pinging by IP. In my example, I was pinging the DNS A record name to see if DNS resolves it.

As for jakematic not trusting to allow the switch internet access, the solution then is to host your own NTP server internally.

Apologies - I meant DHCP and have corrected my reply.

He states he is unable to set DNS manually because his switch is DHCP -vs- static IP
