SRLinux Rancid Module

Summary

Allows using RANCID to extract platform and configuration from the Nokia IXR 7250, IXR 7220, and SXR 7350 series devices.

Currently the attached module and configuration will fetch the following:

show version - Retrieve basic metrics about the system
show platform fan-tray - Retrieve fan tray info

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

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.
