Protected Node Installation

The basics of the Protected Node installation are easy:

  1. Get one of the tarball from
  2. Extract the files under sites/all/modules or some other modules folder
  3. Go to Administer » Site building » Modules and install the module (package Access)
  4. As the administrator (UID = 1) you are done.

Once you have installed the module, you probably want to change the permissions. Permissions allow your users to access the Protected Node functionality based on their roles. Please, see the point about Permissions for more information about those.

Now, you're ready ...

Protected Node (The Drupal module —)

The Protected Node module is used on websites where some pages need to be password protected. This is different from asking someone to create an account and often seen as much more user friendly, although in terms of protection it is quite similar.

If you've seen photo websites where you can go to an album but have to enter a password to see the photos, that's one example how this module can be used.

The module adds a field set in the node form to let authors enter a password.

The module has many options that are rather tricky to use so this documentation tries to explain what you can do

To Do Tokens

The To Do module supports tokens that can be retrieved using the Token module.

The available tokens will generally appear in the list of tokens as found under a text area.

The raw tokens are no representing any security risk. They simply return the raw value instead of a more human representation of the value. For example, when the priority is "High", the raw value is 2.

IPv4 exhausted!

That's it! It's official, the IPv4 address space is now exhausted. This happened this year on February 3, 2011. Now what?

Well, first of all the exhaustion was at the level of the IANA, not for each single Internet provider. This means many more IPs are still available.

However, it is important now for everyone to think of writing any new Internet based software so that it works with IPv61

  • 1. Remember that if you support IPv6, then your system is capable of accessing all IPv4 addresses since the IPv6 address range includes the IPv4. Now let's hope that the IPv6 is not going to be ...

Drupal Aggregator

The default Aggregator Drupal module does not work very well. There are several problems with the Drupal Core module, one of which we have not fixed in our version (i.e. the flatness of the item table.)

There is a list of the known issues and our comments and whether we fixed the problem:

Problem Solution in m2osw's version of Aggregator

Spurious data Some RSS feeds add spurious data ...

jsMath Security Issue

Security Issue

A security issue was found in all versions of jsMath before 2.x-dev for Drupal 6.x of Jul 29, 2010.

You may still securely use older versions of jsMath on private websites and websites were you are the only user (as in, the only one who can log in.)

The Drupal Security Advisory issue is here:

Other Problem

There is another problem: jsMath offers a JavaScript function that parses entire web pages (although there are ways to circumvent that problem, the module does not currently make use of those.) The jsMath Drupal module uses the ...

jsMath Installation


In order to use the jsMath for displaying mathematics with TeX Drupal 6.x module you need:

Upgrade from Table of Contents 2.x to 3.x

Make a Backup


That way you can come back to your previous version if anything goes wrong. So far, no one told me that they had a problem upgrading. Although version 2.x did not have any schema, the new module may modify nodes and generate incompatible tags.

Show stopper

Version 3.x has a new theme() scheme. It is much more powerful has it allows you to create your own header numbering, etc. However, if you already had a theme() overload in your theme, it will stop working until fixed.

Please, in this case, make sure to upgrade on

Table of Contents Settings

Filter Configuration

At this point, most of the Table of Contents configuration is done in the Table of Contents filter.

This means multiple Input formats allow you to make use of several different configurations.
