DNS server not responding

@yodar44 said in DNS server not responding:

how do i set what DNS i am pointing to?

Via your dhcp.. Or directly on your client... What your pointing to there is a IPv6 address for Xfiniity dns..

And that should resolve to
cdns01.comcast.net.

this is my ipconfig/all
Ethernet adapter Ethernet:

the only difference between the LAN and OPT is the .1 on OPT vs .10 on LAN

is that significant?

johnpoz

Well your client there has an IPv6 address... So yeah it perfers IPv6... Which in your setup is pretty hosed since now your asking comcast dns vs your own local dns..

I would suggest you disable IPv6 until such time that you can even get IPv4 working.

@johnpoz
how do i disable ipv6?

johnpoz

The easy way on windows, from an elevated cmd prompt

reg add hklm\system\currentcontrolset\services\tcpip6\parameters /v DisabledComponents /t REG_DWORD /d 255

Reboot

To put it back exactly how it was before

reg delete hklm\system\currentcontrolset\services\tcpip6\parameters\ /v DisabledComponents /f

reboot.

ok, now ipconfig/all says

but nslookup still says
C:\WINDOWS\system32>nslookup
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown
Address: 10.100.1.1

so it seems that something in the pfsense settings is causing the problem. ??

johnpoz

There is nothing in the settings you showed that is odd.. Is it running?

Do you even have connectivity to pfsense? Why is your dhcp lease so short? And such an time?

Up the logging level in the unbound/advanced to atleast 3... And enable logging of queries..

In your options box at the bottom of unbound

server:
log-queries: yes
log-replies: yes

And then we can see what is going on... I don't even think your talking to the pfsense Because your getting timeouts.. So unbound is not running, or you can not talk to it... You have no rules in the floating tab?

is what running?

i can login to 10.100.1.1, if that is what you mean.

i looked in Status/System Logs/Settings, and i don't see these options.
where should i be looking?

johnpoz

That is not where I said to look... I am really starting to think you are just trolling us..

I clearly stated unbound / advanced..

Which you see

Are you not seeing the options box?

yodar44

@johnpoz
ok, i didn't understand where to look.

but now i have new problem. the sg-1100 seems to have failed. i t seems to be completely dead. the pwr light comes on but none of the ports do anything. i tried connecting to the console via putty, no response. also it doesn't get warm any more.
i emailed support to see what to do.
