Restore access to a unifi controller

When you are unable to login to the unifi controller or forgot admin password, you can restore access using SSH and manipulating mongodb directly.

Warning

Do not uninstall unifi controller - most of the data is not stored in mongodb. In case you thought a mongodb backup would be sufficient, you may have fucked up already, just like me. However I managed to write this "tutorial" for anyone to not run into the same trap.

Steps

peelman

Overview

Running Veeam and snmptrapd / snmptt? Want Slack notifications from Veeam for jobs? This script does the following:

• For Jobs: Posts Success, Warning, or Failure messages to the configured Slack Channel
• For VMs: Posts Warning or Failure messages to the configured Slack Channel
• For any unknown messages or weird events, it'll post a generic message containing the pertinent info from the trap.

Traps

peelman

Borrows liberally from the Netmask codebase, but structured to be used more readily in a browser context.

Example:

Subnet.isIP('10.0.0.0')          // true
Subnet.isIP('10.0.0.257')        // false

var subnet = new Subnet('10.0.0.0',12);
subnet.base;                     // 10.0.0.0

subnet.mask; // 255.240.0.0
