SSH Port Forwarding Through a Proxy Server |
| Post date: April 17, 2005, 22:04 Category: Network Views: 700 Comments: 0 |
| Tutorial quote: A common use of SSH is port forwarding (tunneling). This use causes traffic directed to a particular port to be sent to a specified port on another computer.

| Tutorial quote: In paper I have present several features of DNS to make the reader familiar with the basics of the Domain Name System. I have also covered several well known and wide spread attacks that are used to exploit DNS. These attacks are by no means theoretical. In truth they grow more and more common as attackers become more sophisticated. The suggested defense methods outlined at the end of each section cover only the basic recommendations that can be used to thwart attackers. |

SpamAssassin, ClamAV and Procmail Howto |
| Post date: April 15, 2005, 19:04 Category: Network Views: 1130 Comments: 0 |
Tutorial quote: This document describes how to install SpamAssassin (for filtering SPAM) and ClamAV (for filtering viruses, trojans, worms, etc.) and how to invoke them by using procmail recipes. It is suitable for scenarios where Sendmail or Postfix deliver emails to local users. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems. I tested it on Debian Woody so far.
In the end you will have a system where Sendmail or Postfix deliver emails to a local user; the emails are passed to procmail which invokes SpamAssassin and ClamAV in order to filter the emails before they arrive in the user's inbox. However, the installation of Sendmail and Postfix are not covered in this document.
This howto is meant as a practical guide. |
