Every now and then I need a DOS bootdisk to flash a BIOS or similar, and I only have linux with which to create it. I can never remember the quickest way to do this, so I'm documenting it here:

Anyone who uses Putty a lot will inevitably accidentally paste something into their putty window due to Putty's right-click to paste default behaviour, often resulting in pasting relatively embarassing content like SQL that should never be seen in daylight, or at least a customer's root password.
However, I found this putty ...

At NSP we've go a fibre connection into the building, and a 10MBit feed from our ISP, and over that we're allowed 10MBit of national and 3 Mbit PIR of international traffic. Note that this adds up to more than 10Mbit in total! This can cause annoying problems, like ...

One of my evening projects has been setting up OpenNMS to monitor a network primarily comprised of VENDORNAME switches. OpenNMS is being put in to replace a bundle of Nagios, Cacti, Smokeping, and Groundwork Fruity for Nagios configuration management.

I just got a pingback on my earlier post, which was from a blog that indexes posts and articles with a particular word - acceptance - in it. Kind of an odd premise for a blog.

It seems that the original subject of my post yesterday caught the eyes of much of the virtualisation community, including Simon Crosby, formerly from Xensource, and now working for Citrix.
