Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

cinsk

#!/bin/bash

PATH=/bin:/usr/bin:/usr/local/bin

check-nfs () {
    local TMPFILE=/tmp/checknfs.$$ RET=0 ORPHAN SUBSHELLPID

    if [ "$#" -eq 0 ]; then
        cat<<EOF
usage: check-nfs NFS-DIRECTORY...

HOLY GAWD PEOPLE..

• Don't write all your new code on the production machine!
• Use a VCS!
• Document your functions using DocBlocks!
• Document your API (at least LIST the endpoints)... I have to decipher the meaning from your code, and that isn't really clear
• Use a single identifier as the primary ID in the API for a resource (ie don't return a list of group ids for listing groups and then expect the group name as the identifying parameter for modifying a group)
• Use a consistent model for representing the same data model in different endpoints!
• Don't concatenate fields in the API results unless there is a good reason to (e.g first name and last name)
• Don't expose the underlying database logic. This is leaky abstraction, especially when you do it inconsistently!!

Let's Encrypt on Ubuntu 14.04, nginx with webroot auth

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.

As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:

git config --global alias.lola "log --graph --decorate --pretty=oneline --abbrev-commit --all"

1. if you’re on (most modern distributions of) linux, forget that route(1) even exists (and throw ifconfig out in the same go) because it’s just absolutely frustrating. for probably 98% of what you need, ip(1) is the cool you care about

generally speaking, these will cover you: ip route, ip address, ip link

2. when dealing with routing problems (​even if just two hosts next to each other​), mtr > traceroute > ping is an order that’s useful for a lot of what you need

mtr is nice because you can just let it keep running. press d in its display to get a running history breakdown of packets. fantastic for intermittent issues!

traceroute is generally known already, but depending on the complexity of your networks in question you may want traceroute-nanog or similar other ones. some of these are ASN-aware, which is useful.
