Gamemastering book finally complete

Five years, untold drafts, and 330 pages later I finally pressed the publish button on Amazon today for Gamemastering. I was an inch away from publishing it in 2009 but decided to spend more time polishing it.

I’ve got the website for the book all built out and I’m just waiting on the Amazon page to go live before I release the PDF to Creative Commons. From here on out all my blogging for the book will be kept on the official book site.

I have to say this really puts the cherry on top of a great 2010 for me.

Fix the “Using fallback suid method” error message on Busybox (NSLU2)

When you ssh into a fresh SlugOSBE install on an NSLU2 device (or maybe anything running Busybox), an annoying error keeps popping up: “Using fallback suid method”

The simple fix to this is, as root:
touch /etc/busybox.conf

That’s it.

How to configure WordPress for automatic ftps updates using vsftp in Ubuntu

This is a complete guide for setting up WordPress to do secure ftps updates under Ubuntu, tested under Ubuntu 10.10. I assume you have a working WordPress installation and sudo access on the server. If you have any ideas for improving the security of this, please let me know and I’ll update the guide.

Install the vsftp server software:
sudo apt-get install vsftpd

Edit the configuration file for vsftpd to enable ftps:
sudo vi /etc/vsftpd.conf
The following is my entire vsftp.conf file; I shut down anonymous access and even changed the port that vsftpd listens on to throw off low-level script attacks. I stripped out all the nice comments in the file to make this howto a bit more readable. If you paste this in be sure to delete everything else or make sure there aren’t any duplications:

Now start the vsftp server:
sudo start vsftpd

Add a bit of code to the wp-config file to enable uploads:
sudo vi /var/www/wp-config.php
Add the following code to the end:
if(is_admin()) {
add_filter('filesystem_method', create_function('$a', 'return "direct";' ));
define( 'FS_CHMOD_DIR', 0751 );

Now create the ftps user, making their default directory our web directory:
sudo adduser ftps --home /var/www
NOTE: Don’t worry about the warning about the home directory and give the ftps user a good, solid password. Use nonsense words, spaces, and characters like %,$,#. Store the password somewhere safe as you’ll be using this user and password to update WordPress.

Add the ftps user to the www-data group:
sudo vi /etc/group
In that file look for this line:
and add the ftps user to the group by adding ‘ftps’ to the end of that line:

Change the www directory and all files in it to be owned by the www-data group
sudo chgrp -R www-data /var/www

Make the www directory writable by the www-data group
sudo chmod -R g+w /var/www

You can now do updates automatically. Host is the name of your website, plus the following “:2112” – so if your website was, you’d do this:
Username is “ftps” and the password is what you chose earlier. Be sure to select “ftps” as the option. Enjoy!
