Need help with NTP Servers

nwats005 · Dec 2, 2015

Hello I am very inexperienced with freeNAS, I am using it in a small business environment with the 9.3 Stable build. It acts as a file server primarily for us (only 4 clients). I have noticed whenever we save files or create folders directly on the server it is the incorrect time. I did some research and figured it was probably an issue with NTP and the server not being able to access the 3 default NTP servers. I think our freeNAS box can't access the internet in order to sync with the NTP servers. I would like to know what the issue is and would like to even eventually, safely access the server outside of our network to be able to work from home or off site.

Thanks,
Nathan

msk0? really?

So anyways you have a default route. Can you ping things externally?

Presumably you have some sort of NAT gateway at 192.168.1.1. Perhaps it is blocking NTP.

nwats005 · Dec 2, 2015

Not sure what msk0 is. I cant ping anything externally. No I do not have any sort of NAT gateway on the router. Should I? I am not sure how to go about setting that up if I do.

jgreco · Dec 2, 2015

What kind of router is it?

nwats005 · Dec 3, 2015

It is a Verizon MI424WR-GEN3I

Uh. That's a NAT device, just like 99.999% of all home routers....

Do you actually have a name server set up in freenas config?

Correct. That's a """"router"""" (i.e. a NAT gateway), not a router (i.e. a real router, like a Cisco 7609).

So you're saying if you type "ping 8.8.8.8" at a CLI prompt you get nothing?

No I don't have any nameservers set up.

Please explain to us what the benefit of pinging from your client machine is.

You need to ping FROM the freenas box

Then how do you expect the freenas to resolve whatever.com to a valid IP address?

nwats005 · Dec 3, 2015

I don't know, I'm a total noob. I am trying to learn

pirateghost · Dec 3, 2015

So set some valid name servers?

8.8.8.8 and 8.8.4.4 belong to Google

You can likely use your router IP address as its probably listening for DNS requests to forward to your ISP DNS servers

nwats005 · Dec 3, 2015

I set 8.8.8.8 for nameserver 1 and 8.8.4.4 for nameserver 2. When I go to the shell and ping 8.8.8.8 freeNAS keeps pinging and won't stop. What should I check for now that I have those two nameservers established?

Ctrl+C will stop the ping.

Ping Google.com and see if it responds.

OK. DNS is working. NTP should be fine now

nwats005 · Dec 3, 2015

FreeNAS seems to now be connecting to the NTP servers, just created a new file on the server and has the correct time.

Thanks for the help guys.

If I were to go about connecting to the server from home, would a vpn be the best solution? How would you guys go about that?
