NeverSSL – helping you get online

Posted by jpluimers on 2019/11/22

most websites are now using https by default.

And that’s great, but it also means that if you’re relying on poorly-behaved wifi networks, it can be hard to get online. Secure browsers and websites using https make it impossible for those wifi networks to send you to a login or payment page. Basically, those networks can’t tap into your connection just like attackers can’t.

So to get your brain-dead hotel, airport or other WiFi connection to work:

Ubiquity UniFi SDN – Server status “UniFi Controller is starting up… Please wait a moment”

Posted by jpluimers on 2019/02/22

When your UniFi Cloud Key web interface shows this [Archive.is] after upgrading:

UniFi Controller is starting up…

Please wait a moment

Then you just ran into a bug which seems to occur most with 5.9.29 of the UniFi software: [Archive.is] “UniFi Controller is starting up…” “Please wait a moment” “5.9.29” – Google Search

The easiest way is to restore from a backup: this usually works.

For that you need ssh access, which usually is with the ubnt user. But you could have made life more complicated when you followed these:

Steps from [WayBack] UniFi Controller is starting up… Please Wait A Moment – Ubiquiti Networks Community (thanks [Archive.is] About mrfoxdk – Ubiquiti Networks Community!):

SSH to the Unifi CloudKey

dpkg -P unifi

Open a browser and browse the URL of CloudKey

Login

Press “Install” under UniFi

Wait for the process to complete, and then wait a bit for the service to be brought online.

Recover the configuration backup from the latest backup

Removing and reinstalling the UniFi software, then restore from backup

Step 2 above will purge the unifi software of the cloud key as per dpkg --help:

Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection (and a whole bunch of Unifi/Ubiquiti/Ubtn links).

Posted by jpluimers on 2019/01/21

Seems my interest in Ubiquiti needs more research: [WayBack] Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection.

Hopefully by now I’ve time to re-design the WiFi coverage in the house and invest in a few of those access points.

[WayBack 1/2/3] Vincent Parrett commented: I have two of these (along with a cloudkey and edgemax switch) in my house, perfect wifi coverage over the whole house. I’m also using ubnt routers and switches for our servers in the US. Less impressed with the edgerouter pro, has overheating issues due to poor thermal design, but still easy to use and configure etc.

- [WayBack] Use a third party POE switch – Ubiquiti Networks Community
  - Apart from alternatives, this observation “FWIW my experience with the TP-Link SF and SG series switches is poor. I have had more than average hardware failures with these, and some versions silently drop packets (most notably BDPUs if using STP).”
- [WayBack] Solved: UAP-AC-Lite with TP-Link TL-SG1008PE – Ubiquiti Networks Community
- Powering the UAP-AC-Lite with a Mikrotik RB960PGS (also known as hEX PoE) over PoE works fine
Tweakers.net:
PoE from other vendors:
- RB260GSP (does passive PoE only) – [WayBack] POE – UAP-AC-LR with Mikrotik RB260GSP? – Ubiquiti Networks Community
- RB960PGS also known as hEX PoE (does 802.3af, see below)
- Mikrotik needs to make up their mind, as they ship a 24V power supply which cannot power any 802.3af/802.3at devices. The 48POW power supply enables 802.3af for the RB960PGS hEX PoE: [WayBack] hEX PoE (RB960PGS) – Need 48V Power Supply – MikroTik

- 48v PoE should work too, but it is better to assume date code 1646 (officially this is 1641, but not all ones function correctly):
Controller
- The easiest way to configure, is to have a Unifi Controller running in your network.
- The controller can be a [WayBack] Ubiquiti Networks – UniFi® Cloud Key, but does not have to be: a VM, Docker Container, Raspberry Pi, or other solution can work just as well.
- Unifi Controller Versions are released at irregular times, usually at least once a month; I used these places to track them:
  - [WayBack] UniFi Updates Blog – Ubiquiti Networks Community (a bit awkward because the overview has message summaries in addition to the topic)
  - [WayBack] UniFi Updates Blog | UniFi Forum NL (easier to track as the message overview is a simple table that has a message topic column)
  - [WayBack] Chocolatey Gallery | Ubiquiti UniFI Controller 5.8.28
- When using a CloudKey, please avoid sudden power loss: it can brick the database
  - There are various ways to safely power it down:
    - The button on the side is a power down button (see image on the right I got the documentation at [WayBack] https://dl.ubnt.com/guides/UniFi/UniFi_Cloud_Key_UC-CK_QSG.pdf)
    - On the CloudKey interfaces themselves: [WayBack] Solved: Re: Correct way to remove Cloud Key – Ubiquiti Networks Community:
      - There is the “Shutdown” button, in the Unifi Controller UI (https://a.b.c.d.e:8443/manage): Settings -> Maintenance -> Cloud Key Operations -> Shutdown Cloud Key
        
        Similar in the cloud environment as that is a kind of wrapper around the local controller: Settings -> Maintenance -> Cloud Key Operations -> Shutdown Cloud Key
      - There is a “Power Off” button in the Unifi Cloud Key UI (https://a.b.c.d.e:8443/manage/main): Maintenance -> Power Off
  - Resurrecting can be needed, and is relatively easy if you can still SSH into it as root:

  - Sometimes it will not shutdown, so you have to force it, with the risk of having to restore a database backed-up on SD card: [WayBack] Solved: Re: Cloud Key won’t shutdown – Ubiquiti Networks Community
  - More recent CloudKey use a USB C plug, not Micro USB plug [WayBack] Solved: PoE injector for Cloud Key – Ubiquiti Networks Community
  - Powering was a bit tricky:
    - Powering a CloudKey with a TP-Link TL-SG1008PE works fine
    - Powering a CloudKey with a [WayBack] MikroTik Routers and Wireless – Products: hEX PoE (RB960PGS)
      - over PoE fails (it does not come up at all, the Mikrotik PoE led flashes red once when inserting the network cable).
      - over USB fails as well (the CloudKey gets in a reboot loop: white led flashes in the same pattern like for good PoE boot, but goes dark after ~20 seconds, then after a few seconds rinse repeat. This despite the USB 1A power delivery of the Mikrotik: [WayBack] Cloud Key USB-C power adapter recommendation – Ubiquiti Networks Community. CloudKey boot cycle starts a few seconds after the PoE light on the Mikrotik becomes red (meaning PoE is active).
    - Others have better luck on USB: [WayBack] Cloud Key micro-USB power supply electrical requirements (ripple/noise/voltage min/max)? – Ubiquiti Networks Community
    - I have tested the RBS960PGS with firmwares 6.39.2 and 6.42.7 after reading the [WayBack] Manual:PoE-Out – MikroTik Wiki.
    - Passive 48V PoE is also a possible solution: [WayBack] UniFi – Cloud Key Troubleshooting Guide – Ubiquiti Networks Support and Help Center: Powering the UniFi Cloud Key
Configuration:
- Online configuration Portal: https://unifi.ubnt.com/
  - This works way better at device discovery than the Chrome plugin “Ubiquiti Device Discovery Tool” below
  - You can perma-link to your local device; it looks like https://unifi.ubnt.com/5.8.24.0/unifi/site/default/dashboard?d=############000000000#######000000000#######00000000######## where # are digits, 0 are usually zero digits and 5.8.24.0 is .0 prepended by the first 3 parts of your Unifi Controller Version (mine had Version 5.8.24-11016 at that time).

UniFi information:

Splitting 5Ghz and 2.4Ghz SSIDs: two ways (I think the second is cleaner)

Either have one WLAN group with a set of SSIDs, then in each access point disable the 2.4Ghz SSID on the 5GHz radio, and disable the 5Ghz SSID on the 2.4Ghz radio
Have different WLAN groups with an SSID (or set of SSIDs) for each frequency, then in each access point select the appropriate group for each radio

For both the first and second one, you need to configure under “Config” -> “WLANs”.

For the second one, you can clone from the first, then change the SSID names.

Strange MAC addresses starting FA:8F:CA without OUI in your network? They are Locally Administered Addresses and likely from Google.

Posted by jpluimers on 2019/01/07

A while ago, I write about Locally Administered Addresses: a few series of MAC addresses you can use on your local network: MAC address ranges safe for testing purposes (Locally Administered Address).

A while ago, I found ones in my network and ones in my WiFi SSID survey starting with FA:8F:CA. They did not show up in the Wireshark · OUI Lookup Tool nor their manufacturer database.

But with bit 7 turned off they start with F8:8F:CA which does show up as “F8:8F:CA Google, Inc.”

They appear to be Google devices, in my case Google ChromeCast ones, though they can also be Google Home ones.

Google does “magic” with networks, just look at a few of the links here:
