Adding tailscale to an EdgeRouter (and surviving system upgrades)

I suggest you run sudo bash on all of these so you're the root user.

Installing

1. Download tailscale and put the files in /config/. Find the latest stable or unstable version for your EdgeRouter's processor (ex. ER4 is mips and ERX is mipself)

sudo bash    # if you havent already

berkant

## template: jinja
#cloud-config

{% if v1.distro_release == 'focal' %}

users:
    - name: berkant
      shell: /usr/bin/bash
      ssh_import_id: gh:berkant
      sudo: ALL=(ALL:ALL) NOPASSWD:ALL

How to use this script?

Why, that's simple! Copy this script to your USG, run chmod +x on it and then, as a user with sudo permission, execute it.

Shamelessly borrowed from Brittanic on the Ubiquiti Unifi forums

How to use it?

Simply run the following command (note, if you are at all security concious-don't run it and instead review the script, then copy it to your USG to execute).

In order to complete the Minimum Viable Sensu workshop on your own computer, please install the following:

• VirtualBox
• Vagrant
• Vagrantfile provided in this gist
• Centos 7.3 Vagrant box -- should be downloaded automatically

With these applications installed, and the Vagrantfile copied an otherwise empty directory, run vagrant up to download the required Vagrant box and start the VM.

Once the box file is downloaded and the VM is running, use vagrant ssh to log in to the VM via ssh.

I recently switched over to neovim (see my screenshots at the bottom). Below is my updated config file.

It's currently synchronized with my .vimrc config except for a block of neovim-specific terminal key mappings.

This is still a work in progress (everyone's own config is always a labor of love), but I'm already extremely pleased with how well this is working for me with neovim. While terminal mode isn't enough to make me stop using tmux, it is quite good and I like having it since it simplifies my documentation workflow for yanking terminal output to paste in a markdown buffer.

These days I primarily develop in Go. I'm super thrilled and grateful for fatih/vim-go,

To limit a CPU to a certain C-state, you can pass the processor.max_cstate=X option in the kernel line of /boot/grub/grub.conf.

Here we limit the system to only C-State 1:

    kernel /vmlinuz-2.6.18-371.1.2.el5 ... processor.max_cstate=1

On some systems, the kernel can override the BIOS setting, and the parameter intel_idle.max_cstate=0 may be required to ensure sleep states are not entered:
