Creating a Web-based BBS, Part 2

Mr. Lerner continues to look at the bulletin board system, examining the code that works with individual messages.

The basic BBS software is now finished. It can create threads, add a message to a thread and view the messages within a thread. If nothing else, this project shows how powerful a set of database tables can be when paired with some CGI programs.

Perhaps this system is too basic; it is lacking some functions that any good bulletin board (or any good web application) should handle. For instance, it would be nice to include the ability to search through the posted messages for a text string or regular expression to find messages relevant to a particular topic.

It would also be useful to provide some administrative functions, unavailable to the public at large, for handling things at a relatively high level. For example, we might want to reserve the ability to delete messages that are offensive or unrelated to the topic. We might even want to give this ability to certain other users, giving them “deputy moderator” status.

Next month, we will see how to provide these functions by adding just one or two new CGI programs. Meanwhile, you can see these programs in action at, where the “At the Forge” BBS is already in use.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
