|
Friday, 01 June 2007 |
|
Since it’s been a while since I last posted, I thought I’d bring you
all up to date with the new Mandriva release. Spring beautiful spring!
For the last month (and a bit) I’ve been running Mandriva 2007.1
Spring PowerPack on my Toshiba Satellite 2410. To avoid people having
to skip to the conclusion, I’m sticking with Mandriva Linux Spring on
my laptop permanently!

Howto install a content filtering and virus checking proxy (Part II) |
|
Friday, 11 May 2007 |
|
Commercial filters are often expensive, especially when used on a large number of computers, as would be the case in a school computer lab or in small or medium companies with computer networks. In contrast, open source filters are generally freely available for download. In addition, since commercial filters are proprietary, in many cases the system administrator does not have the opportunity to modify or even view the lists of blocked sites.

Howto install a content filtering and virus checking proxy (Part I) |
|
Wednesday, 11 April 2007 |
All Internet content carries a risk. Content Filtering helps companies and home users to stop unwanted data. It is used as part of Internet Firewalls or Proxy Servers to screen the content of all incoming Internet traffic. Content filtering usually works by specifying character strings that, if matched, indicate undesirable content that is to be screened out. Content is typically screened for pornographic content and sometimes also for violence- or hate-oriented content.
To be effective you need a database or list of domains and URLs that should be blocked. Building and maintaining your own blacklist would require a huge investment in time. In the first part (Part I) of the workshop we will use a downloaded list which you can later update on the regular bases.
Part II of the workshop will explain how to add a virus scan engine to the existing configuration using ClamAV.

Open source at CeBIT 2007 |
|
Friday, 23 March 2007 |
|
Traditionally, most companies that work with open source software
cluster at the Linux Park in Hall 5, and this year was no exception.
Nor was there any exception to another CeBIT tradition, namely the
release of a new version of Knoppix, which is now at version 5.2.
However, this time Klaus Knopper -- Mr. Knoppix himself -- wasn't
handing out free disks and answering visitors' questions. Instead,
German publisher Heise was selling copies of its C't magazine
containing the latest version of Knoppix.
