I wanted to write this post for two reasons:

1. to remind everybody that we (the Dokeos company) continue to vaguely support this mode because we understand it is still more practical when installing it on a free/cheap hosting server
2. to help you avoid the tricky issue in the installation process when deciding which main db name to use

As the first point is pretty much complete, I'll go straight to the second point. In the Dokeos installation process, the database configuration screen asks you for a prefix and a database name.

Debian GNU/Linux is one of the main and earlier GNU/Linux distribution. You may wonder why it is our preferred distribution.

A NIDS is a Network Intrusion Detection System, a system to detect intrusions from the network and take counter-measures ranging from (temporarily) blacklisting to logging through responding with specially crafted IP packets to slow down or kill the attacking host. It extends the principle of IDS to the network.

Yes, we have our first annoying bug in Dokeos 1.8.5.

There is a common problem appearing when installing a new Chamilo portal that I have seen a lot recently, so I thought I'd share the details here.

The problem

When installing Chamilo on a cPanel-kind-of-hosting, it might happen that you complete the installation, but when you want to enter a newly-created course, an ugly error appears.

Mailman is a very flexible and powerful mailing-list manager written in Python. We use it to communicate internally, as well as with partners and customers. It's fully managable by e-mail or web interface.

Here are a few examples you'll probably find useful at some point. Counting the number of lines of a C project

$ wc -l `find -name "*.[ch]"|xargs`

Execute a command on a directory and all its subdirectories

$ find "path" -exec "command" {} ;

Deleting all the files not accessed for 1 day in the current directory and all its subdirectories

$ find .

grep is a tool to extract text lines from files (or command outputs using pipes).

SSH (the Secure SHell) is a secure replacement for many UNIX tools like telnet, ftp, rsh, rcp, rlogin, rexec, and many more, which have proven to be insecure, even if most UNIX systems still use them by default, and even Microsoft has now begun to integrate those into his operating systems. I'll talk about the most used one, and free OpenSSH, which has been created by the OpenBSD team.

Pagers are commonly used under UNIX, because many, many documents are just plain text or text output of other commands or tools. The best known is more because it's also the oldest still living out there. less or most are clones, which bring together a lot of missing features to more and can be used to completely replace it.
