Configuring Boot2Docker to use NFS on an OSX based machine

To improve the speed of Boot2Docker drastically, you will want to set it up to use NFS.
You will need to do the following once on your host machine:
- Add this to /etc/exports on your mac
```
# BOOT2-DOCKER-BEGIN
/Users 192.168.59.103 -alldirs -mapall=501:20
# BOOT2-DOCKER-END
```

Docker Registry API V1 walkthrough

This document summarizes the interactions between the Docker client and the Docker Hub during push and pull commands through version 1 of the registry API. It was compiled to aid in writing a compatible registry server implementation after the existing API documentation proved occasionally incomplete or inaccurate.

Behavior and code links were as of Docker v1.2.0.

docker {push|pull} H:P/R[:T]
Host, Port, Repository ([namespace/]image), Tag

Quick 'n dirty testing regexes for Windows volumes

See docker issue moby/moby#16140

This regex captures Windows paths nicely;

^[a-zA-Z]:(\\[^\:\\]+)*\\?$

And long paths (e.g. \\?\C:\Program files (x86)\notepad.exe):

Simple Two-Factor SSH Authentication

Posted on September 23 2011 by Richard Taylor (@moomerman)

In a two-part post I'm going to show you some tricks you can do with SSH logins. This post covers setting up two-factor SSH authentication with the Google Authenticator app.

I was recently getting some servers in shape so I can pass the Payment Card Industry standards questionnaire and one requirement was two-factor authentication access to the server. I queried whether SSH key + passphrase was acceptable but didn't get a clear answer so I figured I'd explore setting up another authentication factor myself, plus it piqued my interest.

After a bit of research I found it was possible using a PAM module but it doesn't work along with SSH key authentication (only password authentication) and I only use SSH key logins for my servers.

The magic

the grand idea

I like public key auth. I feel safer using them instead of a username and password login. But, I might not have my private key with me at a time where I need access.

I started using yubikey with LastPass and since I have it always on my keychain, I decided to find more ways to make use of it.

I wasn't originally aware, but if you pass a private key to ssh and sshd is configured to accept a key, it appears pam isn't used. Your authorized keys are checked and you are logged in. If you don't pass a private key, ssh falls back to the more standard un*x style login found in /etc/pam.d/sshd. This is where we'll add the yubikey pam. I am currently unaware of a way to use both public key auth and yubikey for login.

These steps worked for me on debian squeeze/wheezy.
