AFAIK : he doesn't use the Forwarding mode. He's resolving.
What have you set here :
?
And the main Resolver setting :
right ?
edit :
@RickyBaker Let's forget the GUI, you (we) are dealing with lots of info here, and the GUI is nice, but not fast enough.
Go console or SSH that's the access you need. (and this isn't an over statement).
Get in.
Console menu option 8.
Type
cd /var/log/
ls -al resol*.*and now you see the main reslver.log file, and the x rolled over log files.
tail -f resolver.logand now your looking at the resolver log file, in real time.
This will 'stop' or 'hang' after moments, as the file '"resolver.log" already reached its maximum size, so it gets rotated by the 'syslog' daemon into (for example resolver.log will get rename din resolver.log.0 and resolver.log.0 will get renamed in resolver.log.1 etc etc. And a new empty resolver.log will get created ....but our tail command is tailing a file ... that doesn't exist anymore.
Hence the need of comfortable huge log files .... but keep in mind the disk space left, right ;)I don't see any "query:" or "reply:" lines ... ?!

I'm losing my mind:
My wife is going to kill me, she can't use her computer. She asked if we should call our ISP shudder but i don't think it's an issue with the ISP, right? Once again I go back to how sudden this problem came about without changes and how prevalent it has become....
Is there any indication the pfsense hardware is failing? Anything?

My MyQ wifi garage door opener is offline now too, i'm rolling back those changes i guess...

removed those Custom options, and restarted the resolver and the internet came back for my wife. Maybe i should've attempted to just restart the resolver first?

Sorry for the slightly off topic q, but i, as @johnpoz suggested, feel that updating to 2.7.2 is my next logical step (but I can't do it from the gui or console). So I made a bootable usb stick with 2.7.2 and started the process....but then i forgot the options I selected when I first installed pfsense years ago. Is there a way to check on the gui or console which option i selected for ZFS or UFs? Or which drive I installed it to? I thought my Dell r210 II only had one drive in it but I was presented with 2 during the installation (maybe a partition) and I didn't remember which I did. I just want to make sure my installation is exactly the same as the original to avoid issues.
edit: safe to assume this means zfs on a single drive?
Also I read online there would be an upgrade option when I loaded up a flashable usb with psfense already installed on the target media but this was not a presented option....I also read online that this means the installation media can't read the pfsense install....how much should I be reading into this?
-
@RickyBaker ZFS was released with 2.6.0 so when did you install yours? Or check the dashboard Disk widget. In general you’d want ZFS.
Re upgrading, one can’t do that like you’re describing I think. However this is a thing: https://docs.netgate.com/pfsense/en/latest/backup/restore-during-install.html#recover-config-xml-from-existing-installation. Or just restore after.
The installer may show the usb stick? Can you tell by size?

As you can see, "just download pfSense" isn't an option anymore. It's gone. From now on, you load an installer, never used myself that one before.
This must be it : the online installer.I also upvote the upgrade to 2.7.2.
You'll be using a far newer unbound version, probably "1.19.3."About the install media : forget about CD, DVD etc.
Use : Prepare a USB Memstick.
If the stick isn't broken, it works. Tried this method several times on Netgate devices an bare bone stuff like your device.@RickyBaker said in DNS_PROBE_FINISHED_NXDOMAIN sporadically for anywhere from 30secs to 10min. works flawlessly at all other times:

Ah, ok, you have a 2.7.2 on USB ready.
When installing on a device, known, or not, try to know what de 'FreeBSD' name of the hard disk is. There can be one or more drives. I say drive name, not the partition names on that drive as they will will be lost.
If you can chose, go for the best file system : ZFS.
Enumerate also your NIC names : you can see them in the Interfaces >Interface Assignments menu.
And thats all there is to do.
Go for a manual default bare bone 192.168.1.1/24 LAN and DHCP WAN setup, if you can.
Make a backup of your current config first.
When installing, I never 'recover' the config (if found). I test the system first with the 'everything to default' settings. When that works out : LAN and WAN (and unbound ^^) ok, then you can import your backed up config later on using the GUI.
If any issues come back at that moment : you know it's your config ;) -

I test the system first with the 'everything to default' settings.
because of the sporadicness of the issue, it's going to be very difficult to test the default settings. Any suggestions? i don't want to set up all the downstream devices to deal with the new ip address et al.
and slightly off topic/dumb q: is there a way for me to view any and all drives pfsense sees in the GUI or the command line?
-
cat /etc/fstab -
@Gertjan anyway to see the sizes of these? I tried a bunch of ls commands that were all not included in pfsense (and apt wasn't either)
I found camcontrol devlist:
I dunno waht that middle ahci is or the sized of the hard drives but it really would appear i have 2 500gb hdd's in there (the 2 wdc above)...
geom disk list got me sizes:
I genuinely can't remember instaling a second harddrive in there but here we are. would you guys agree that's what it looks like?
-
I have no idea what's happening. I booted from the installer USB drive and the installation seemed a little different. It didn't request ZFS or UFS (or the other 3 options this time) and I got through the selection of interfaces and right to the installation selection an got this error when attempting to access the Netgate servers:
When I switched back to booting off the included hard drive (my old configuration, everything came up alright, but I had no internet. and the homepage of pfsense read that it was unable to check for updates:
Is this a crazy coincidence of my ISP going down the exact minute I tried to install the new pfsense or could I possibly have done something to the internet connection while powering down the modem and trying to install the newer version? Soooo frustrating either way!
Edit: I needed to tether to the hotspot of my mobile to write this post, as this post loaded but said there were issues connecting to the negate servers. But I was able load other pages on my phone and laptop. It's almost like negate was alone blocked on my ISP, so weird!
Edit2: There seems to be no issue with internet or connecting to the netgate forum now. Maybe it was the worlds world coincidence

since the homepage was again displaying that I was "up to date" even though I was on 2.7.0 I decided to reattempt all the suggestions in this thread: https://forum.netgate.com/topic/184670/issue-with-going-from-2-7-0-to-2-7-2/15
And it worked! no scary full reinstall. I'm on 2.7.2 and I will report back. Though after the weird issue with Netgate Servers being unable to be contacted I restarted my AT&T FIber ONT and haven't noticed an outage since (thought it was only a day).....In any event i'll be back here to report any developments

@SteveITS said in DNS_PROBE_FINISHED_NXDOMAIN sporadically for anywhere from 30secs to 10min. works flawlessly at all other times:
update: https://forum.netgate.com/topic/187506/kea-dhcp-feature-roadmap/6
So is it safe to switch over?

@RickyBaker if you need just basic dhcp and not the missing features it should be fine. Or just wait until it’s not a preview.
You can also switch back.
