Ubiquiti UniFi Account/User Credentials Cheatsheet

If your brand-new network is set up by UniFi Network iOS app. and using existing Ubiquiti account [email protected] for sync (the option Enable Local Login with UBNT Account will be enabled automatically if you login your Ubiquiti account during the setup), there’s what you will get:

Router, Security Gateway aka. USG

  • Web login:
    • User: admin or custom defined
    • Password: Random-generated during your first setup via iOS app. You need to checked “Enable SSH authentication” in order to change your USG username and password at the time of writing (UI version: 5.10.23.0). It can be found in UniFi Controller Web UI (under Settings – Site – Device Authentication, then click the eye-shaped icon to reveal the password)
  • SSH login:
    • User: admin or custom defined
    • Password: same as USG login credentials

Switch, aka. USW

  • SSH login:
    • User: admin
    • Password: same as USG login credentials

UniFi Cloud Key, aka. UCK

  • UniFi Controller Web UI:
  • UniFi Cloud Key Web UI:
  • SSH login:

UniFi Cloud Key: MongoDB Out of Memory Issue

You may find the following issue if you run a UniFi setup:

tail -f /srv/unifi/logs/server.log

...
Wed Jun 27 21:52:34.250 [initandlisten] ERROR: mmap private failed with out of memory. You are using a 32-bit build and probably need to upgrade to 64

After googling for it you may find a Ubiquiti staff post a prune script on their forum.

But you may find that script can only be executed while the MongoDB is running. However no one mentioned how to solve it when you can’t start your MongoDB. Here’s the solution, actually you don’t even need to repair your database in this situation:

Make sure unifi service is stopped:

systemctl stop unifi

Download the prune script from Ubiquity support

wget https://ubnt.zendesk.com/hc/article_attachments/115024095828/mongo_prune_js.js

Start a new SSH session, run MongoDB without --journal, all others parameters are copied from the unifi service:

mongod --dbpath /usr/lib/unifi/data/db --port 27117 --unixSocketPrefix /usr/lib/unifi/run --noprealloc --nohttpinterface --smallfiles --bind_ip 127.0.0.1

Run the prune script:

mongo --port 27117 < mongo_prune_js.js

You should get the similar output:

MongoDB shell version: 2.4.10

[dryrun] pruning 0 entries (total 0) from stat_minute... 
[dryrun] pruning 56 entries (total 56) from stat_monthly... 
bye

Then edit the prune script and rerun the prune script with dryrun=false:

MongoDB shell version: 2.4.10
connecting to: 127.0.0.1:27117/test
pruning data older than 7 days (1541582296632)...

{ "ok" : 1 }
{ "ok" : 1 }
bye

Start the unifi service

systemctl start unifi

The root cause of this issue is that Cloud Key is currently running on ARMv7, a 32-bit based custom Debian system. so MongoDB cannot handle data larger than 2 GB. I haven’t tried the Cloud Key 2 and 2 Plus I hope they’re ARMv8 based. At the moment you can limit data retention as a workaround.

UniFi Security Gateway (USG) Decrypt Error (Inform Error, aka “Adopting” Loop) for v4.4.28 Firmware

This is a known issue (bug) with USG 4.4.28.* firmware confirmed on official beta forum, the error would be like:

Sep 26 22:38:55 main-router mcad:  ace_reporter.process_inform_response(): Failed to get the decrypted data from custom alert response#012
Sep 26 22:38:55 main-router mcad:  ace_reporter.reporter_fail(): Decrypt Error (http://192.168.1.10:8080/inform)
Sep 26 22:39:10 main-router mcad:  mcagent_data.data_decrypt(): header too small. size=0, should be=40
Sep 26 22:39:10 main-router mcad:  ace_reporter.process_inform_response(): Failed to get the decrypted data from custom alert response#012
Sep 26 22:39:10 main-router mcad:  ace_reporter.reporter_fail(): Decrypt Error (http://192.168.1.10:8080/inform)
Sep 26 22:54:31 main-router mcad:  mcagent_data.data_decrypt(): header too small. size=0, should be=40
Sep 26 22:54:31 main-router mcad:  ace_reporter.process_inform_response(): Failed to get the decrypted data from custom alert response#012

Solutions (try them in the following order):

  • Disable period speed test
  • Reboot the controller
  • Force provision the USG
  • Try official unifi-util patch
  • Reset USG and readopt it
  • Upgrade/downgrade to a previously working version

Mine got everything back to work after resetting the USG.

Some tips:

You can run info to get some basic info what’s going on with your USG:

[email protected]:~$ info

Model:       UniFi-Gateway-4
Version:     4.4.29.5124212
MAC Address: 78:8a:20:7c:ba:1d
IP Address:  11.22.33.44
Hostname:    main-router
Uptime:      192 seconds

Status:      Connected (http://unifi:8080/inform)

HTTPS on UniFi Cloud Key, with Remote Access Support, the Easy Way

You can try this method if you meet one of the following situation:

Requirements

  • A public IP to the internet (to access Unifi Security Gateway remotely)
  • A server running Nginx on public internet
  • A CA issued certificate

Set port forwarding for your Cloud Key

In general, you can access your Unifi Secuiry Gateway (USG) via your public IP (USG_IP), so in my method you need to forward your UCK management dashboard (UCK_IP:8443 by default) traffic to your public IP. it’s under Settings – Routing & Firewall – Port Forwarding. Enter your Cloud Key address IP as Forward IP, use default 8443 as Port and Forward Port. You can also limit from destination to your server IP for security best practice.

Setup Nginx proxy

Use the following Nginx configuration, please note that this is a simplified version.

server {
  listen                  80;
  listen                  [::]:80;

  server_name             unifi.example.com;

  return                  301 https://$server_name$request_uri;
}

server {
  listen                  443       ssl http2;
  listen                  [::]:443  ssl http2;

  # To avoid unreachable port error when launching dashboard from unifi.ubnt.com
  listen                  8443       ssl http2;
  listen                  [::]:8443  ssl http2;

  server_name             unifi.example.com;

  # Certificate
  ssl_certificate         /etc/nginx/ssl/unifi.example.com.crt;
  ssl_certificate_key     /etc/nginx/ssl/unifi.example.com.key;

  location /wss {
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header CLIENT_IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_read_timeout 86400;
    proxy_pass https://USG_IP:8443;
  }

  location / {
    proxy_set_header Host $http_host;
    proxy_set_header CLIENT_IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_read_timeout 180;
    proxy_pass https://USG_IP:8443;
  }
}

Update DNS records

Point your unifi.example.com to your public IP, access it in your browser, everything now should works!

This article describes how to access the emergency recovery UI and recover a Cloud Key. From this UI you can reset it to factory defaults, reboot, shutoff and upgrade the firmware. To upgrade the firmware you will need a firmware binary for the UniFi Cloud Key.
