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

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

Send Slack Message

Simple Ruby script that sends a slack message. Like Slackcat or others, but I needed more options. Uses slack-notifier gem.

YMMV.

Overview

This is a quick nagios plugin / script to query an ESXi server and grab the "overall status" parameter. This is a parameter each host should respond to and will reflect if any alarms are active on the system. See the official documentation for more info.

This should give notice in the event of a power supply failure, memory errors, loss of connectivity to datastore, etc.

The script only requires a Hostname, but allows for the providing of both a hostname and IP address. The hostname is required to make sure that the status being returned is for the correct host (I don't trust CIM to always return the hosts inside the "hostFolder" in the same order). It is actually used to query the API for the provided string, so it must be accurate and reflect what the system thinks its hostname is. Our environment and conditions mandated this. YMMV.
