Monitors and displays

| No Comments

If anyone has an elegant solution to extending gnome panels over multiple monitors, please let me know!

I other news, if you have two monitors and stack them with the panel on the top of the bottommost monitor, you'll discover how gnome handles hiding panels. Set the panel to auto-hide and it'll just slide up to the bottom of the top monitor! That's not hiding my panel anymore, that's just making it really hard to control the screen layout.

More and more I find myself just using a whole pile of screen sessions and putting jobs in the background...this makes for quite a mess when I need to reboot.

Also, if you have one of those convenient USB hubs on your monitor, make sure that you know which one your keyboard and mouse are plugged into before you go shutting off monitors!

Drupal and Shibboleth

| No Comments

With the imminent switch to Shibboleth, I've decided to try out hooking up a Drupal instance...to...Shibboleth. Exactly as the title implies.

I'm using Ubuntu Server 10.04 for my server and rather then authentication against a real IdP, I'm using the public TestShib Two service as an IdP and configuring the SP myself.

Here's how I did it:

0) Register with OpenIdP and get a machine ready for testing.

1) Install the necessary packages:
apache mpm-prefork
php5
libapache2-mod-shib2
mysql (for drupal)!
...and all their friends.

2) Get drupal and install that properly. There are plenty of tutorials out there on how to do this.

3) Configure your apache server so that it looks something like this:



ServerAdmin webmaster@localhost
ServerName x-128-101-79-21.pop.umn.edu
UseCanonicalName On

DocumentRoot /var/www

Options FollowSymLinks
AllowOverride None

Alias /secure /var/www/drupal

Options Indexes FollowSymLinks Multiviews

Order allow,deny
Allow from all

AuthType Shibboleth
ShibRequireSession On
require shibboleth


...and a whole bunch more as needed. You can actually base it off the default-ssl site (...like I did.)

4. Somewhere in your shibboleth2.xml (probably in /etc/shibboleth), you have something that looks like this:









This is the really important part. It's telling you exactly which paths on the server are going to be secured by
