Advanced Internetting: Password Managers

Image via datenform.de

Did you know that your LinkedIn password is on display in a German Museum? Is your password “123456?” How’d I guess?  Well, it’s the most common password in use today. Scary isn’t it? Here’s something truly terrifying: for 20 years, the US secret nuclear launch code was “00000000.” Even if you aren’t launching nukes, your passwords are important. Why are they important? Unless you want someone you don’t know to have access to your Facebook, Gmail, and Twitter accounts, you need to care about your passwords.

Advanced Internetting: Two Factor Authentication

Earlier this week, I discovered that GitHub supports two factor authentication, and I emailed all my coworkers, explaining what it is, why it is important, and how it works. Since I’ve already done the leg-work, I figured I should post it here, too.

Raspberry Pi Mail Server: Final Touches

Updates: It turns out the relayhost setting below didn’t work for me. Here’s what I did instead.

If you’ve read any of my prvious posts about this (previous posts listed here), you’ll know they pretty much all included a “Next Steps” section. I have finally finished everything on the lists, so unless I discover I’ve done something wrong, or I think of something else this needs, I should be done with this project. Here’s what was left, which I’ll cover in this post:

Building a Raspberry Pi Mail Server: Why

Updates: @seanbonner has a great post on privacy vs security, which really gets at the heart of what I was trying to say at the end of this post, but in a much more easy to understand way. You should really check it out.

I also blogged about the technical details of how I build the mail server. That post is here.

My Rasberry Pi Mail Server

For a long time, I’ve used Google for mail, calendar, and contact storing and syncing. I also used it for RSS. When Google announced they were shutting down Google Reader, I sort of panicked and started moving all of my various web stuffs off of free services. I moved my Tumblr and Blogger blogs to Hostgator WordPress instances, tried multiple new RSS readers, and tried replacing Dropbox, Google Calendar, and Google Contacts with Owncloud. Most importantly, I moved 6 years of email off of Gmail and into Hostgator’s mail servers.

Building a Raspberry Pi Mail Server: How

My Raspberry Pi Mail Server - Pre-assembly

My Raspberry Pi Mail Server – Pre-assembly

Now that I’ve ranted about why I decided to build my own mail server, it’s time to explain how.

In order to build my own mail server, I decided to use Postfix and Dovecot on a Raspberry Pi. I chose these three very specifically. Postfix and Dovecot are the go-to for building a mail server, and Raspberry Pis have been the home server of choice ever since they were announced. By selecting these, I was certain I would be able to get the most community support, and I would be able to find the most comprehensive guides on how to set everything up.
