PiHole DNS not Responding, disk full

The Internet seemed unreachable at my house. After checking with the provider I determined it was due to my pihole being down.

Logging into the dashboard of my pihole showed "Lost Connection to API". This indicated an issue with the pihole-FTL service.

After logging in the Unify CloudKey where I installed pihole I used df -h to determined that the disk was full

root@UniFi-CloudKey:~# df -h Filesystem Size Used Avail Use% Mounted on aufs-root 2.9G 2.9G 0 100% / udev 10M 0 10M 0% /dev

It was due to 3 things:

apt cache at "/var/cache/apt/archives"

CloudKey backups at "/data/autobackup"

pihole-FTL database at "/etc/pihole/pihole-FTL.db"

You can cleanup the first using "apt-get autoclean". For the second, you can manually delete some of the old backups but perhaps you should set a better backup policy in your CloudKey.

The third one accumulates all the queries ever done against your pihole (18M in the past 2 years for me) unless you set something like MAXDBDAYS=90 in /etc/pihole/pihole-FTL.conf. Mine was 1.4GB.

You can stop the pihole-FTL with "service pihole-FTL stop", delete the file, and restart it, if you want. Or perform a more surgical cleaning directly deleting old entries from the database before restarting it.

A follow up to Proxmox, PiHole and IPv6

So, per that post, I "needed" the IPv6 ULA addresses for PiHole.

Learning is growing, and growing is learning, and it turns out, you just flat out didn't need the IPv6 ULA addresses - I sussed this out as part of the great USG to UCG migration. These ULA addresses were done in config.gateway.json, which does not exist with the UCG line.

So back to these two jobs:

Tell PiHole where to send forwarded requests (in this case, the UCG)

Configure the network to use PiHole

Nice and easy!

Copy the UCG's Link-Local IPv6 Address and paste it in as an IPv6 forwarder

Copy the Link-Local IPv6 Address of the PiHole, and paste it in as the "DNS Servers" heading under the IPv6 DHCP settings. Ensure that the DNS "Auto" settings are not enabled to allow the DNS servers to be modified.

That's it! Easy! Done!

Restart Unifi CloudKey Gen 2 PoE from switch SSH command line

I have a Cloud Key Gen 2 that has been replaced twice and is now acting up a third time. Anyway, I needed to reboot it remotely as the drive is a 2 hour trip to this particular Cloud Key. If you have SSH enabled, log in to your switch and, with proper documentation, find the port number that you need to reboot and run this command: swctrl poe restart id [port number] Example: swctrl poe restart…

I know I'm a week late but I do think people are misunderstanding the point of the Anthony Bourdain quote about Kissinger

The point was never "Anthony Bourdain has good politics and is an unproblematic fave," the point is that even someone with mainstream liberalish politics who goes to Cambodia for a food tour - a, let's be honest, very bougie type of trip to be part of your job - and has a basic understanding of history and a bare minimum of human decency can come away from that bougie food tour wanting to murder Henry Kissinger with their bare hands. The point is that Henry Kissinger fucked up this country so bad the only reason he wasn't lynched decades ago is because it's on the opposite side of the world and the people who were in proximity to him never really saw what it was. The point is that if we could see firsthand what our First World politics do to the Third World we would understand that monsters walk among us and it's a cultural failing that we let them die at home at 100 years old surrounded by their friends and family.

The not-so-great USG to UCG Migration

This post is about the big old move from Ubiquiti's EdgeOS based USG line to their new UnifiOS range at two sites. There were a few reasons for me doing this to myself;

Old/Legacy devices - the USG line was recently made "Legacy" by Ubiquiti - this has the obvious implications of it in the future no longer receiving security and feature updates

Complex to do anything not in the controller - I refer of course to "config.gateway.json". I'm sure some people love it, but frankly I hated it, and especially with one of my sites being remote, I dreaded making a change in that space because it may bring things down and throw me into a provisioning loop

Site Magic - Site Magic is the "new" way to do Auto IPSec VTI, and is instead done with WireGuard. It also means you don't have to do as many changes when a new site's added, and subnets can be added/removed from the "SD-WAN" as needed

Downsizing - I'm trying to downsize the presence of any on-prem equipment at one of the sites, and if it means I'm running a few less VMs and containers for VPN and a Unifi Controller, then it's a win in my book.

Power savings - The USG-Pro-4 has a max power consumption of 65W! Crazy! The UCG Ultra has a max of 6.2W, so much friendlier!

Beefier CPUs - The USG-Pro-4 didn't seem to be as much of a problem as the USG 3 here, but both were beginning to show their age a bit

Mostly feature parity - the things I used config.gateway.json for were more or less null/void after many years of updates to the UnifiOS platform. For example, Conditional DNS is now a thing in UnifiOS. I also didn't really have a need for virtual interfaces any more.

So the USG-Pro-4 is being replaced with the UCG-Ultra, and the USG-3 is being replaced with the UCG-Max

On with the fun!

First was the UCG Ultra.

And my gripes with this start with the fact that, there's no real clear documented process on moving from a USG on a self-hosted container - for all intents and purposes, it's just "backup and restore", which did not bear much fruit for me.

My trouble starts as below:

Take Settings Only backup and a Site Export and restore those to the UCG -No good - the Controller just rotates the loading symbol and doesn't export the Settings Only backup. The Site Export works a treat, but the UCG won't import it

Try and SSH into the controller and get a copy of the generated Settings Only backup file -No good - the UCG does not accept it

Use an older backup file which can be downloaded from the controller -No good - when restored to the UCG, it restores as you would expect. But because in Unifi-land, you can only have one gateway per site, the UCG just doesn't work and essentially ignores the settings etc. in the backup file. The devices show, but the UCG itself does not act as if it's connected/part of the network, instead referencing a "Third-Party Gateway". Very confusing and the lack of doco on this was just bonkers

A power outage mid-restore -Definitely no good. This happened mid-restore and didn't help as I'd left that site in an absolute state and had to talk someone through getting things back up and running with the USG-Pro-4

So I left this, and given the power was due to be back at 7pm the next day, I went to the other site, and attempted that. I more or less encountered exactly the same, with the exception of, there was no power outage there. Bummer.

However, I did have some time, once things were up and running from Point 4, to investigate the issue with the Settings Only backup. Turns out, there was an older config.gateway.json file that was using incompatible characters in the file name. Once that was taken care of, the Settings Only backups started.

The next afternoon, I attempt to get this going again.

Armed with a working controller, I follow the below steps:

Take a Settings Only backup from the controller

Forget the USG-Pro-4 from the Controller and unplug it from power

Take another Settings Only backup from the controller

Ensure the UCG is connected from its WAN port into the modem, and connect the power. Leave the LAN connected to the device that's being used to connect

Set up the UCG as you see fit

Open the Unifi Network application on the UCG and restore the 2nd backup (from Step 3). As I was running Multi-Site, I was prompted to pick which site I wanted to restore from and confirm.

Give it 5 or so minutes, and restart the UCG

It should fire up using the original network details/IP addresses/range etc. as the original USG - confirm this is the case

Any additional Unifi Devices (Switches, APs, etc.) will show as offline - this is expected as they're still associated with the old controller.

Unplug the device you're working on from the UCG and back into the "old" network. Set a static IP and navigate back to the controller

In the settings, set "override set-inform host" to be the IP address of the UCG. The devices will show as Offline in the old controller.

Plug the device you're working on into the UCG, and plug the UCG into the LAN also. Devices should appear and show as adopting/provisioning.

That should be it - for me, things were cooking and working as expected, so I was glad that was it after that. Any changes etc. can be made and will be applied. I recommend taking a backup at this point also

So that's the UCG Ultra done. Sweet!

That night, I go to tackle the UCG Max. See below:

Navigate to the self-hosted controller and forget the USG 3. I didn't power mine down, but I did unplug the LAN/WAN

Take yet another Settings Only backup

Refer to the above steps for the UCG setup (4-9)

I note now that I have devices that aren't associated, but this time, not to any controller - strange. I SSH into the devices and set their set-inform to the Dynamic DNS host I have for the site where the self-hosted controller lies. No change, and they still don't show up in either controller

I re-SSH into the devices noting that of course, override set-inform was still set and overriding what I set in ssh... Hmm.

Navigate back to the controller, disable override set-inform

SSH into the devices, set the new set-inform URL

The UCG now showed the switches and APs, and all was fine and well with the world. I took a backup and now I can rest.

How tiring...
