HOWTO: Gracefully Shutdown VirtualBox VMs on Reboot or Shutdown of Ubuntu

Monday, February 23rd, 2009

I always forget I have a GUI virtual machine open when I go to shutdown, usually because it is on another desktop, out of sight. This howto will show you how to avoid the same thing, and to put any VMs you have open into a saved state, ready for a quick start up next time.

Before we go any further… (more…)

Sometimes it’s better to just do one thing at a time…

Over the last couple of days, I have been trying to get the vboxtool script working in order to safely shutdown any virtual machines I leave open on secondary desktops. Seems to work fine with headless VMs but not the one opened up in the GUI form on the desktop. Anyhow, had a Vm open on second desktop. (more…)

How to Share from Linux using SSHFS on Windows with Dokan

Saturday, February 14th, 2009

Dokan, (meaning clay pipe) providing sshfs access to linux file shares (server) from Windows systems (client)

I am always looking for good ways of accessing linux file system shares from windows boxes, as I have to help my less technical windows users on my LAN gain access to everything being served up from my linux servers. If samba doesn’t float your boat, and getting nfs to work on Windows is just too hard, there is another way; dokan, which runs as an executable on Windows systems (W2K,XP, Vista) to provide mounted network style shares via ssh. Here’s how.

This howto is aimed at an internal LAN, so low security measures are followed. I am sure there are ways to lock things down as tight as you want (probably from the linux end), but this is beyond the scope of this howto, I just want to get you up and running! (more…)

***Health & Safety Warning and Disclaimer***

Before you try this, I must issue a Health and Safety warning on the electrical front, and also a disclaimer that I can accept no responsibility whatsoever if you try this and it a) borks your equipment, b) kills you or anyone else.

PLEASE NOTE THAT ALL SOLUTIONS MENTIONED HERE ONLY APPLY TO LAPTOP PLUG-INS AND NOT TO DESKTOP COMPUTERS WHICH REQUIRE 3-PRONG PLUGS.

If you bypass the grounding system of a desktop computer, you will put human lives at risk of fatal electrocution.

That said, you should bear in mind that if you have a 3 pin power plug (UK) and you go abroad to the continent or the USA, you would use an adapter to remove the earth connection, and all your power supply and laptop are double insulated for your safety. many DJs have found the need to do something along the lines listed below to get rid of interference when using laptops (more…)
