VPS upgrade

TransIP already announced the upgrade of their virtual private servers about a month ago. Today my VPS – the one this website runs on and more – was upgraded. From 1 GiB memory to 4GiB, from 100 GB disk to 150 GB, and from 2000 GB traffic per month to 5000 GB per month. And all that still for € 20 per month. Not a bad deal at all!

We will setup SSH access in two phases:

  1. Setup basic SSH with the normal login credentials
  2. Secure access further with a key

Create a virtual private server

It is almost the end of February, so it is the perfect time for some new year’s resolutions: I am going to document a number of tasks that I have performed to my personal server that is connected to the world wide web.

The first task is arranging a platform to play with. In my case I ordered a Blade VPS L from the Dutch company TransIP. My VPS is about to be upgraded to a Blade VPS X4. With 4MB RAM instead of the current 1MB that is a lot better. TransIP also manage my domain names. So far I would recommend them without reservation.

The end-result of this exercise is a running VPS with a fully up-to-date, but bare, Ubuntu Server installation.
