Colin's Journal

Some of yesterday had to be spent doing website and system maintenance. The first change to my website is that double spaces after a full-stop are now preserved using non-breaking space characters. Currently this only applies to those pages that I created in a text editor, but I hope to implement this for OpenOffice pages in the future.

A small number of people have recently started using my images in their websites and using my webserver to serve them. While I can’t do much to stop people copying the images, I can at least use Apache’s mod-rewrite to block my webserver from being used to host them. There are two downsides to this: direct links to my images from other sites will no longer work, and image search sites such as Yahoo and Google will not display my images correctly in their search results page. To link to one of my images from a website the link must now go to the HTML page that contains the image rather than the image directly.

On my home computer I’ve added a white-list of users that are allowed to SSH in. This means that I can give guests weak, easy to remember, passwords on my computer without it being vulnerable to a dictionary attack on the network. For the technically curious this was done by using the PAM listfile module in /etc/pam.d/sshd.
