My little mail server

What a pile of poo! I have access to four smtp servers and they all have limits on the distribution list size! (They are all about the same size of 100). Google will allow 2000 per list but only if you use one of their clients. Let’s try and bring up an SMTP server, connect it to DNS, and then send them myself. Sounds like a job for AWS.

Ruggedising the Internet

Mike Masnick writes a little article forecasting the engineers re-writing the single points of failure out of the internet. He entitles his article, Building A More Decentralized Internet: It’s Happening Faster Than People Realize. He cross references to two articles written by himself back in 2010, Operation Payback And Wikileaks Show The Battle Lines Are About Distributed & Open vs. Centralized & Closed and The Revolution Will Be Distributed: Wikileaks, Anonymous And How Little The Old Guard Realizes What’s Going On in which he, more accurately, recognises the current and future power of distributed and private networks.

While researching this I came across a page on alternate roots at Wikipedia.


ddclient is a program for Linux that negotiates with to allow systems with dynamic tcp/ip addresses to have static DNS names. This was originally written in 2011, and revisited in 2013. dyndns abandoned their free product some time ago, possibly as a result of being bought by Oracle. I marked the page is ‘deprecated’ on 4th Feb 2019. The rest of this article comprise my notes on how to install ddclient on an AMI.  Continue reading “ddclient”
