EDIT: this works but causes sendmail to pause for ~1 minute when it can't find its own FQDN; this slows boot (if sendmail is started at boot and not backgrounded) and would be un-workable on a busy mail server.

Here's how to configure sendmail to send mails when the computer is configured with a hostname but no domain name. It may be of use, for example, if you want to mail system exception reports and do not want to configure the computer as being part of a...

Don't turn off security features, customise them!

I’ve noticed a worrying trend recently. People seem to be hell bent on ‘turning off’ prompts for the root password to perform various admin level tasks because it’s ‘annoying’. In a similar way, one of the main criticisms of Vista has been User Access Control and much has been written about turning that off. Indeed, Microsoft seem to have taken this criticism on board and allows users to easily turn UAC off! Great! Just because users are lazy and impatient, turn security off!

I just read this article and it struck me that, in the last few paragraphs, there's an ever so subtle hint that there may be alternatives to suffering the constant barrage of malware and the resultant rounds of critical updates. It's not often you see that!

A quick review of Slackware 13 and KDE 4.3.1 on my old laptop...

I posted this as a thread, but it makes a good blog entry:

This past weekend I installed Slackware 13_x86 on my IBM A22m laptop. The laptop is a Pentium III 1 GHz with 512 MB of RAM.

I was running Slackware 12.1 on this computer, so before I started I backed up my /etc, /home, and /root directories onto my desktop computer and then reformatted the hard drive. This gave me a clean slate for the new installation.

For the installation, I selected all of...
