Enter your Ubuntu credentials

This is an update of a previous post, found here. I’ve added a section to the bottom which explains how you can connect to the same session each time.

If you need to connect to a Linux machine, and in the scope of this guide, Ubuntu 14.04 (I’m sure this guide should be fine for earlier versions as well), then your options include:

  • Pure and simple SSH – The admin’s super tool! (just install openssh-server – works every time!)
  • VNC – I don’t like this method because you need to install software on your client AND server
  • XRDP – This still involves VNC to some degree but you can use the normal Windows Remote Desktop Client

The latter is the one I’ll guide you through here. Continue reading

RAID Config Screen

In this day and age, you need your machines to be up and running 100% of the time, or as close to that as possible. This means that rebooting a server just to get some detail about your RAID configuration is completely out of the question.

Luckily, some RAID cards have the ability to be configured even from a running system. In the case of this article, we’re looking at LSI or PERC (As the Dell guys call them) cards.

Raspberry Pi Logo

If you want to run a slide show or something similar on your Pi, you don’t want to constantly go into ‘screensaver mode’ or ‘energy star’ mode.

This guide is based on Raspbian, fully updated as at 4 Aug 2014.

If your Pi runs X by default, you can disable the screensaver or power saving mode as follows:

# Edit the /etc/X11/xinit/xinitrc file and add the following three lines at the bottom of the file
xset s off         # don't activate screensaver
xset -dpms         # disable DPMS (Energy Star) features.
xset s noblank     # don't blank the video device

If you run the console by default, but still want to prevent the screen from going blank, you can do it with the following single command:

sudo sh -c "TERM=linux setterm -blank 0 >/dev/tty0"
